Abstract: An auxiliary-recharging system of engine-driving type battery for automatically monitoring operation, it uses engine generator as power source of auxiliary electric energy to proceed auxiliary recharging for driving loading motor and vehicle-loading battery. The battery is detected by manual operation device or operating mode of central control unit referring to storage status measuring apparatus. According to the detecting result to do relative operation. And selectively set portion or full operating performance according to its application. The operating performance include: (1) According to the battery saturation status detection, when the battery storage amount is lower than the preset value, start the motor to drive the engine and generator to recharging the battery. (2) Compare the battery saturation status signal with operating mode of central control unit to modularize generator for input potential to motor or battery. (3) According to the battery saturation status detection to control the generator and battery for driving motor. (4) Detecting the loading current status of motor as the battery driving the motor alone, and determining the necessity of starting the engine and generator. (5) Accepting the operation from manual control apparatus to drive engine and generator for driving motor. (6) Accepting the operation from manual control apparatus to start engine and generator with fixed or controllable current & power for driving motor and recharging the battery. (7) Accepting the operation from manual control apparatus to start engine and generator with fixed or controllable current & power for driving motor by battery and generator. (8) Accepting the operation from manual control apparatus to start engine and generator for recharging the battery alone. (9) Accepting the operation from manual control apparatus to start engine and generator for recharging the battery with settable recharging current, power and time. (10) Detecting the saturation status of battery at (1)(8)(9) recharging operation for stopping engine generator. (11) Detecting the saturation status of battery at (2)(6) recharging operation for stopping recharging operation without stopping output potential to motor. (12) Detecting the saturation status of battery at (2)(6) recharging operation for stop engine generator and let battery drive the motor. (13) Detecting the saturation status of battery at (2)(6) recharging operation, and the engine generator and battery output potential to motor together. (14) Detecting the recharging current at (1)(2)(6)(8)(9) as generator recharging the battery or/and deriving motor for modularizing the generating power. (15) Monitoring the concentration of harmful gases around the environment, if it above the safe value then stop the operation. (16) Monitoring the temperature of environment, when it above preset value, then stop operation. Through above system, let the battery has better pre-load status. It is not only good for the system operation, but also prevent the battery discharge too much and longer the life of battery.
