[0046] As shown in FIG. 10, it is a circuit diagram of the high temperature protection module 9. According to the working temperature, such as (0 °C-60 °C), during the use, when the internal temperature is higher than the safe value of 60 °C, the internal controller 4 will automatically shut down, stop working, the internal temperature drops to Normal operating temperature (below 50 °C) can automatically resume work. Take the first level of protection for automatic shutdown and recovery. In the case of failure of the first-stage protection, in order to achieve safer protection, the internal temperature is protected by the second level. When the internal temperature reaches 80 °C, the operation is automatically shut down and stopped, and the internal temperature drops to the normal operating temperature ( The work can be resumed automatically. In the case of failure of the first and second levels of protection, when the internal temperature reaches 100 °C, the third level protects and automatically shuts down the device, and the entire product stops working forever. Because the battery is at 130 ° C The situation may cause an explosion, so the internal temperature of the third-level protection must be controlled within the safe range.

[0047] As shown in FIG. 11, it is a circuit diagram of the low temperature protection module 10. In the low temperature state, the method of safe automatic temperature rise is adopted to reach the normal temperature (o°c) or above, and the normal operation is automatically resumed, which not only ensures the emergency start of low temperature in winter, but also ensures the safety and reliability of the battery.

[0048] As shown in FIG. 12, it is a circuit diagram of the fire protection protection module 11. In order to avoid sparks during use, avoid danger and explosion, and personal injury, use internal control method and buffer work protection.

[0049] As shown in FIG. 13, it is a circuit diagram of the reverse connection detecting protection module 6 and the short circuit protection module 12. The short circuit and reverse connection of the positive and negative poles are protected. The internal setting automatically recognizes the control system. In the case of incorrect connection, the automatic alarm and stop work greatly protect the normal use and personal safety of the product. The internal controller 4 can be automatically activated and works normally only when the external connection is normal.

[0050] As shown in FIG. 14, which is a circuit diagram of the inflation detecting protection module 5, when it is detected that the inflation range of the battery 2 exceeds the set value, the battery 2 stops supplying power.
