Thus, the first information supplied from the individual residence  100  can be supplied, through the Internet  400 , as the second information to the shop  200 , the automatic vending machine  300 , and the like. 
     The management device  900 K is capable of deriving risk information based on the usage information of the cartridge battery  120  and the unique information of the battery  122 .

     In the charging method, for example, the amount of the electric power  23  supplied from the charging control circuit  151  to the battery  122 , the time of charging, and the like, are designated. For example, the charging control circuit  151  controls the cartridge battery charging power supply  23  according to the instruction of the operating terminal  153  to thereby charge the battery  122 . In the present embodiment, the power supply converter  152  converts the solar-generated electric power  21  generated by the solar power generator  170  into the cartridge battery charging power supply  22  of a power supply method and a voltage suitable for charging the battery  122 . Moreover, the power supply converter  160  converts the household power supply  18  into the cartridge battery charging power supply  19  of a power supply method and a voltage suitable for charging the battery  122 .

     On the other hand, the management device  900 K, when outputting a non-permitting signal, outputs, along with the non-permitting signal, a command signal for executing recovery of the cartridge battery  120 . The operating terminal  153  displays, on the display device  6 , an indication of instructing execution of recovery. Thereby, the cartridge battery  120  with the performance thereof having been deteriorated is excluded from circulation and, for example, sent to the maker of the battery  122  for maintenance or reuse. By recovering the cartridge battery, resource recovery is possible. 
     In the present embodiment, the management device  900 K is capable of selecting a power generation method to be used for charging the battery  122 , based on a signal input received from the input device  7  through the Internet  400 .

     Next, there is described in detail an operation of the entire battery system  1  according to the present embodiment, with reference to  FIG. 1  to  FIG. 7 . 
     First, there is described, with reference to the flow chart in  FIG. 7 , an operation in a case of charging the cartridge battery  120  of the home battery  110  at the individual residence  100 . 
     The operating terminal  153  of the cartridge battery charger  150  reads the ID  10  from the cartridge battery ID  121  of the cartridge battery  120  (STEP  1 ). 
     The ID  10  is a unique number or the like assigned to an individual cartridge battery  120 . 
     Next, the operating terminal  153  converts the read ID  10  into the Internet data  11 , and transmits it as the Internet data  12  via the Internet  400  to the management server  910  at the battery management center  900 . 
     The management server  910  checks the ID  10  from the received Internet data  12  against the battery management data  13  on the database  920  (STEP  2 ), and reads information related to the battery  122  of the cartridge battery  120  indicated by the ID  10  (STEP  3 ). 
     In the present embodiment, the information related to the battery  122  includes information related to charging (discharging) history of the battery  122  (number of cycles), and unique information related to the battery  122  (name of maker, name of product, type of product, battery rank, number of allowed charging/discharging cycles, and the like). 
     The management server  910  transmits the read information related to the battery  122  as the Internet data  12  through the Internet  400  to be received on the operating terminal  153  as the Internet data  11 . 
     The operating terminal  153  reads information related to the battery  122  from the received Internet data  11 , adds “1 cycle” for the current charging/discharging cycle to the number of charging/discharging cycles, and then compares it with the number of allowed charging/discharging cycles (STEP  4 ). 
     If “the number of charging/discharging cycles is less than or equal to the number of allowed charging/discharging cycles”, the charging will be commenced and the operating terminal  153  will instruct, with a screen display on the display device  6 , to select a power generating method (STEP  5 Y). 
     On the other hand, based on the received information related to the battery  122 , the operating terminal  153  outputs, to the charging control circuit  151 , charging control information  14  that instructs an optimal charging method according to the battery  122  related information (name of maker, name of product, type of product, battery rank, number of allowed charging/discharging cycles, and the like) of the battery  122  to be charged and the current number of charging/discharging cycles. 
     If “the number of charging/discharging cycles is greater than the number of allowed charging/discharging cycles”, charging will be impossible and the operating terminal  153  will onscreen-display on the display device  6  that charging is impossible, and will display a screen to instruct recovery of the battery (STEP  5 N). 
     In a case where recovery of the battery is instructed, the cartridge battery is returned to a recovery agent or battery maker to get the resource recovered, and is reused for a new cartridge battery. 
     In the selection of a power generating method, a power generating method is selected between nuclear power generation, oil-fired power generation, coal-fired power generation, hydraulic power generation, wind power generation, solar power generation, and the like, and use of nighttime use of electric power or the like is selected. For example, in a case where the nuclear power generation and nighttime electric power are selected, then within a period of time in which nighttime electric power is applied, the nuclear-generated electric power  15  generated by the power generator  951  at the nuclear power generating station  950  is converted into the cartridge battery charging power supply  19  by the power supply converter  160 , with use of the electric power supplied as the household power supply  18  to the individual residence  100  via the power transmission/distribution network  980 , and output to the charging control circuit  151 . 
     Moreover, in a case where the solar power generation is selected as the power generating method, charging is performed with use of the solar-generated electric power  21  generated with the solar light  20  irradiated on the solar power generator  170  disposed at the individual residence  100 . The solar-generated electric power  21  is input to the power supply converter  152  of the cartridge battery charger  150 , and converted into the cartridge battery charging power supply  22 . 
     The cartridge battery charging power supply  22  is output from the power supply converter  152 , and input to the charging control circuit  151 . The charging control circuit  151  charges the battery  122  of the cartridge battery  120  with an optimal charging method according to the charging control information  14  input from the operating terminal  153  (STEP  6  and STEP  7 ). 
     Having completed charging, the operating terminal  153  outputs the charge completion and the power generating method as the Internet data  11 , via the Internet  400 , to be received on the management server  910  at the battery management center  900  as the Internet data  12 . 
     The management server  910  adds 1 cycle of the current charging to the charging/discharging history (number of cycles) of the information related to the battery  122  of the cartridge battery  120  indicated by the ID  10  on the database  920 , and updates it along with the power generating method. 
     The management server  910 , according to the updated information related to the battery  122  (charging/discharging history of the battery (number of cycles), name of maker, name of product, type of product, battery rank, number of allowed charging/discharging cycles, and the like) and the database  920 , calculates the amount of accumulated electricity in the battery and the risk thereof. 
     The database  920  has a charging/discharging characteristics database based on battery maker, battery product type, number of charging/discharging cycles, and charging method, and it is possible, if updated information related to the battery  122  (charging/discharging history of the battery (number of cycles), name of maker, name of product, type of product, battery rank, number of allowed charging/discharging cycles, and the like) is given, to calculate the amount of accumulated electricity when fully charged (for example, AH (ampere hour)) and the risk thereof (for example, %). 
     The battery management server  910  transmits the calculated amount of accumulated electricity in the battery and the risk thereof as the Internet data  12 , via the Internet  400 , to be received on the operating terminal  153  as the Internet data  11 . 
     The operating terminal  153  reads the amount of accumulated electricity in the battery and the risk thereof from the received Internet data  11 , and displays it (STEP  9 ). 
     In the above description, there has been described the operation of charging the cartridge battery  120  of the home battery  110  at the individual residence  100 . 
     Next, there is described, with reference to the flow chart in  FIG. 7 , an operation in a case of using the cartridge battery  120  of the home battery  110  at the individual residence  100  that has been charged. 
     First, on the operating terminal  153 , there is input usage information of the battery  122  to be used (purpose of use (electric motorcar, electric motorcycle, or electric bicycle) and the information thereof (name of maker, type of vehicle, name of product, year of make, and the like)). 
     The operating terminal  153 , as with the case of charging, reads the ID  10  from the cartridge battery ID  121  of the cartridge battery  120 . 
     Next, the operating terminal  153  converts the input usage information of the battery  122  and the read ID  10  into the Internet data  11 , and transmits it as the Internet data  12  via the Internet  400  to the management server  910  at the battery management center  900 . 
     The management server  910  checks the usage information of the battery  122  and the ID  10  from the received Internet data  12  against the battery management data  13  on the database  920 , and reads information related to the battery  122  of the cartridge battery  120  indicated by the ID  10 , the amount of accumulated electricity therein, and the risk thereof. 
     The management server  910 , based on the usage information of the battery  122  (purpose of use (electric motorcar, electric motorcycle, or electric bicycle) and the information thereof (name of maker, type of vehicle, name of product, year of make, and the like)), the information related to the battery  122 , the amount of accumulated electricity therein, and the risk thereof, calculates a possible travelling distance based on the usage information of the battery  122  and the risk thereof. 
     The management server  910  transmits the calculated possible travelling distance, the risk thereof, the information related to the battery  122 , the amount of accumulated electricity therein, and the risk thereof, as the Internet data  12  through the Internet  400  to be received on the operating terminal  153  as the Internet data  11 . 
     The operating terminal  153 , reads from the received Internet data  11 , the possible traveling distance, the risk thereof, the battery information, the amount of accumulated electricity therein, and the risk thereof, and displays them on the display device  6 . 
     Moreover, the operating terminal  153  calculates a charging cost (yen), carbon tax (yen), and CO 2  emission amount (kg) based on the amount of accumulated electricity, the risk thereof, and the power generating method, and displays them on the display device  6  (STEP  10 ). 
     In the above description, there has been described the operation in a case of using the cartridge battery  120  of the home battery  110  at the individual residence  100  that has been charged. 
     The charging operation and use operation after charging at the shop  200  such as a convenience store, home center, and charging station, are also similar to the operation performed at the individual residence  100 . 
     At the shop  200 , a number of charged cartridge batteries are available, and a purchaser can freely select and purchase a battery by comparing, on the operating terminal  223 , the battery information, possible traveling distance and the risk thereof, cost, carbon tax, and CO 2  emission amount, of each cartridge battery. 
     When purchasing a cartridge battery at the shop  200 , a purchase cannot be made unless a used cartridge battery is recovered in exchange. 
     On the other hand, the charging operation and use operation after charging in the case of the cartridge battery automatic vending machine  300 , are also similar to the operation performed at the individual residence  100 . 
     In the automatic vending machine  300 , as with the shop  200 , a number of charged cartridge batteries are available although the availability thereof is not as high as that at the shop  200 , and a purchaser can freely select and purchase a battery by comparing, on the operating terminal  323 , the battery information, possible traveling distance and the risk thereof, cost, carbon tax, and CO 2  emission amount, of each cartridge battery. 
     When purchasing a cartridge battery from the automatic vending machine  300 , a new charged cartridge battery cannot be purchased unless a used cartridge battery is inserted. 
     Moreover, it is possible to automatically charge the recovered used cartridge batteries with use of the solar power generator  340  to thereby repeatedly sell them. 
     In the above description, there have been described the operation at the time of charging and the operation at the time of purchasing a charged battery, at the shop  200  such as convenience store, home center, and charging station, and at the cartridge battery automatic vending machine  300 . 
     A cartridge battery charged at the individual residence  100 , a cartridge battery purchased at the shop  200 , and a cartridge battery purchased from the cartridge battery automatic vending machine  300 , can be inserted into the electric motorcar  500 , the electric motorcycle  600 , or the electric bicycle  700 , to be thereby used for its intended purpose. 
     In a case of the electric motorcar  500 , it is possible to mount a plurality of the cartridge batteries  510 . Moreover, the electric motorcar  500  has, in addition to the battery  512  of the cartridge battery  510 , the main battery  520  mounted thereon, and when travelling normally, the main battery  520  supplies the main battery output driving power supply  51  to the electric motor  530  to thereby perform traveling, while the battery  512  of the cartridge battery  510  is used only when the main battery  520  becomes empty. 
     Also in a case of the electric motorcycle  600 , it is possible to mount a plurality of the cartridge batteries  610 . Moreover, in a case of a large electric motorcycle  600 , as with the electric motorcar  500 , a configuration is also possible where a main battery is mounted in addition to the battery  612  of the cartridge battery  610 , and when traveling normally, the main battery supplies main battery power supply to the electric motor  620  to thereby perform traveling, while the battery  612  of the cartridge battery  610  is used only when the main battery becomes empty. 
     In a case of the electric bicycle  700 , as with the case of a current electric bicycle, traveling is possible only by inserting the cartridge battery  710 . 
     At the emergency disaster shelter  800 , there are a plurality of the cartridge batteries  820 ,  830 , and  840 , and the emergency battery  810 , into which the cartridge batteries  820 ,  830 , and  840  can be inserted, and each user brings and inserts a charged battery for use. For example, the cartridge battery is transported on an electric vehicle including at least one of the electric motorcar  700 , the electric motorcycle  600 , and the electric bicycle  700 , and thereby the cartridge battery can be brought in. 
     The cartridge battery emergency power supply  55  output from the batteries  822 ,  832 , and  842  of a plurality of the cartridge batteries  820 ,  830 , and  840 , is input to the power supply converter  850  and the emergency communication device  860 . 
     The power supply converter  850  converts the input cartridge battery emergency power supply  55  into the emergency power supply  56  that can be used as household power supply, to be used as power supply at the emergency disaster shelter  800 . 
     Moreover, the cartridge battery emergency power supply  55  input to the emergency communication device  860  is directly used as power supply for the emergency communication device  860 , and the emergency communication device  860  transmits and receives emergency communication data  57 , to be thereby utilized for emergency communications. 
     The emergency communication device  860  can have a cartridge battery directly inserted therein, and can therefore be portably used. Moreover, a used cartridge battery is brought into an area not affected by the disaster to be charged, and it can be taken back to be repeatedly used. 
     As described above, according to the present embodiment, there is used the cartridge battery  2  that is detachable (exchangeable) and easy to transport and that has the same outer shape and size, and it is consequently possible to manufacture a large quantity of only a single type product for various types of applications including not only the electric motorcar  500  but also the electric motorcycle  600 , the electric bicycle  700 , the home battery  110 , and the emergency battery  810 . Furthermore, standardization is also possible. If standardization is realized, it will become possible, regardless of maker or product type, to manufacture only a single product type of the cartridge batteries  2 , thereby reducing the cost. 
     Moreover, in the present embodiment, in a case of operating an electric motorcar or large electric motorcycle that requires a large capacity and takes a large scale battery, for example, the main battery required for the electric motorcar to travel is equipped on the electric motorcar as a large scale fixed battery, and this is complemented by an exchangeable cartridge battery  2  that has a battery capable of accumulating an amount of electric energy only for minimum traveling. Thus, it is possible to reduce the size of the cartridge battery  2 . Consequently, anyone including the owner of the electric motorcar can easily replace the cartridge battery  2  without an exchange facility. 
     Moreover, a preliminarily charged cartridge battery  2  and a used cartridge battery  2  can be easily and instantly exchanged, and it is consequently possible, even in a case where the battery  2 V is empty, to eliminate need for charging time. 
     Furthermore, the cartridge battery  2  according to the present embodiment can be easily transported and can be charged anywhere, while allowing a selection of electric power of an energy source of the cartridge battery, that is, electric power of an energy source of the electric motorcar  500 , the electric motorcycle  600 , the electric bicycle  700 , the home battery, and the emergency battery  810 . Consequently, with use of carbon-free electric power or electric power with a low CO 2  emission amount, it is possible to reduce CO 2  emission and thereby reduce carbon tax. Moreover, it is possible to reduce electricity cost using electric power at midnight, and a self-owned solar power generator at an individual residence can be used. 
     Moreover, a plurality of the cartridge batteries  2  according to the present embodiment can be detached, can be easily transported, and have the same outer shape and size, and their battery charging history, the battery information, and the like are centrally managed using individually unique IDs (identifiers). Consequently, the cartridge battery  2  is such that only the accumulated electric power energy can be purchased and the main body of the cartridge battery  2  is circulated (re-used and circulated), and it is therefore possible to eliminate the need for purchasing an expensive cartridge battery every time. 
     Moreover, a plurality of the cartridge batteries  2  according to the present embodiment can be detached, can be easily transported, and have the same outer shape and size, and it is consequently possible to use the cartridge battery  2  for any one of the cartridge battery of the electric motorcar  500 , the cartridge battery of the electric motorcycle  600 , the cartridge battery of the electric bicycle  700 , the home battery  110 , and the emergency battery  810 . That is to say, the cartridge battery  2  can be transported and can be made a versatile common standard battery for multiple purposes. 
     Moreover, according to the present embodiment, the cartridge battery  2  can be detached, can be easily transported, and has the same outer shape and size, and it can be charged anywhere and does not require an exchanging facility. 
     Furthermore, the cartridge battery  2  can be charged at any one of the individual residence  100 , the shop  200  such as convenience store, home center and charging station, and the cartridge battery automatic vending machine  300 . A charged cartridge battery can be exchanged or purchased. Moreover, the cartridge battery  2  can be exchanged anywhere including a home, convenience store, automatic vending machine, home center, and road. Thus, the cartridge battery  2  does not require an exchanging facility and can be made a versatile common standard battery, and it can be detached and charged on any electric power. 
     Furthermore, the cartridge battery  2  is such that it is detachable, can be transported easily, has the same outer shape, only accumulated electric power energy is to be purchased, and the main body of the cartridge battery is circulated (re-used and circulated), and also the number of charges of all of the cartridge batteries, deterioration in performance, and the like are centrally managed at the battery management center  900 . Thereby, it is possible to stop battery-use of all cartridge batteries at an appropriate time with no omission, and to reuse them as resources. Consequently, the cartridge battery  2  enables effective use of resources. 
     Moreover, the cartridge battery  2  can be easily transported, has the same outer shape and size, can be charged anywhere, does not require an exchanging facility, and can be detached and charged on any electric power, and consequently energy transportation becomes possible with use of the cartridge battery  2 . 
     Furthermore, the cartridge battery  2  can be easily transported, does not require an exchanging facility, has the same outer shape, can be detached and charged on any electric power, and can be used anywhere, and it is consequently possible, in the event of a disaster, for individuals to bring and connect a plurality of the cartridge batteries  2  to thereby use them as a large-capacity emergency power supply device, while it is possible, in a case where the batteries are empty, to individually charge them to thereby continuously use them as a large-capacity emergency power supply device. 
     Moreover, as the cartridge battery that forms the emergency battery  810 , it is possible to use at least one of the cartridge battery  510  used for the electric motorcar  500 , the cartridge battery  610  used for the electric motorcycle  600 , and the cartridge battery  710  used for the electric bicycle  700 . 
     Furthermore, in a case of the electric motorcar  500  that requires a large capacity, there may be freely made an optimal design to achieve maximum performance while taking efficiency into consideration, in which rather than dividing the main battery required for travelling into a plurality of units, only the cartridge battery with a separate battery capable of only accumulating a sufficient amount of electric energy to enable minimum traveling is made exchangeable, and the large-scale/large-capacity main battery required for the electric motorcar  500  to travel is provided as a fixed battery. 
     In the embodiment described above, on at least one of the electric motorcar  500 , the electric motorcycle  600 , and the electric bicycle  700 , there may be equipped a charger capable of charging the battery  2 V. 
     In the embodiment described above, a fixed battery may be disposed at the individual residence  100 , the shop  200 , the automatic vending machine  300 , and the like. The cartridge battery  2 , when electric power supply from the power generating stations  950 ,  960 ,  970 , the solar power generator, or the fixed battery, to the electrically powered device  3  at the individual residence  100  and the shop  200 , and in the automatic vending machine  300  is stopped, is capable of supplying electric power to the electrically powered device  3 . 
     According to the present invention, a cartridge battery is made a versatile common standard battery that can be used for multiple purposes such as an electric bicycle battery, an electric motorcycle battery, and a home battery, and thereby it can be applied to many purposes. Particularly it is normally used as a home battery for accumulating energy for home power generation and self power consumption developed in response to CO 2  reduction; it is detached to be used as an electric motorcar battery when using an electric motorcar; it is detached to be used as an electric bicycle battery when using an electric bicycle; and it is detached to be used as an electric motorcycle battery when using an electric motorcycle. These ways of use are effective methods of utilization. Therefore, a contribution to industrial development can be made. Moreover, by gathering the cartridge batteries and connecting a number of the cartridge batteries in the event of a disaster, they can be used in conjunction for active usage as an important energy source in evacuation life.
