[0013] 1. In the utility model, when the charging device is charging the battery, the pin inside the output connector will generate temperature, and the temperature is transmitted to the heat conducting plate. The temperature of the heat conducting plate is detected by the temperature sensor and the data is transmitted to the central processing unit. When the data is higher than the set threshold, the central processing unit transmits a signal to the control module, and the control module controls the circuit breaker to disconnect the output line to cut off the power, thereby preventing the battery from generating high temperature and causing danger.

[0022] The control box 10 is provided with a central processing unit inside, and the central processing unit is electrically connected to the input line 12 and the output line 14 through a step-down converter, which reduces the external 36V voltage to a 3-5V voltage available to the central processing unit;

[0023] At least three pins 19 are arranged inside the output connector 16 (one of which is a ground pin, and the remaining two are positive and negative pins respectively), and a heat conducting plate 18 is arranged on the outer surface of the pin 19. During the charging process, the heat generated by the pin 19 is transferred to the heat conducting plate 18, and the outside of the output connector 16 is connected to the temperature sensor 17, the temperature sensor 17 is connected to the heat conducting plate 18, the temperature sensor 17 is electrically connected to the central processing unit, the central processing unit is electrically connected to the control module, and the control module is electrically connected to the circuit breaker.

[0024] In this way, when the charging device is charging the battery, the pin 19 inside the output connector 16 will generate temperature, and the temperature will be transmitted to the heat conducting plate 18. The temperature of the heat conducting plate 18 will be detected by the temperature sensor 17 and the data will be transmitted to the central processing unit.
