A management system for a power transmitter capable of wirelessly transmitting power to a power receiver of a movable object in response to a charging request, the management system comprising: a detection unit configured to detect a temperature in the power transmitter; a storage unit configured to store an identification rule indicating a relationship between the temperature in the power transmitter and a power transmission level indicating possibility of power transmission of the power transmitter, and a limit value of an allowable range of the temperature; an identification unit configured to identify the power transmission level corresponding to the temperature detected by the detection unit with reference to the storage unit; and an output unit configured to output the power transmission level identified by the identification unit before the power transmitter starts transmitting power, wherein the power transmission level is determined by a relationship between the detected temperature and a desired charging time, or power amount, of the charging request and includes at least an unavailable level indicating that power transmission is impossible, a limitation level indicating that power transmission is possible under a predetermined limitation, and a normal level indicating that power transmission is possible without limitation, wherein the identification unit is further configured to identify that the power transmission level is the limitation level if the temperature detected by the detection unit will exceed the allowable range during a requested charging, and wherein the output unit transmits the identified power transmission level of the power transmitter to a terminal of a user of the movable object together with a position of the power transmitter, whereby the terminal displays the power transmission level and the position of the power transmitter. a detection unit configured to detect a temperature in the power transmitter; a storage unit configured to store an identification rule indicating a relationship between the temperature in the power transmitter and a power transmission level indicating possibility of power transmission of the power transmitter, and a limit value of an allowable range of the temperature; an identification unit configured to identify the power transmission level corresponding to the temperature detected by the detection unit with reference to the storage unit; and an output unit configured to output the power transmission level identified by the identification unit before the power transmitter starts transmitting power, wherein the power transmission level is determined by a relationship between the detected temperature and a desired charging time, or power amount, of the charging request and includes at least an unavailable level indicating that power transmission is impossible, a limitation level indicating that power transmission is possible under a predetermined limitation, and a normal level indicating that power transmission is possible without limitation, wherein the identification unit is further configured to identify that the power transmission level is the limitation level if the temperature detected by the detection unit will exceed the allowable range during a requested charging, and wherein the output unit transmits the identified power transmission level of the power transmitter to a terminal of a user of the movable object together with a position of the power transmitter, whereby the terminal displays the power transmission level and the position of the power transmitter.
