[0002] The Chinese invention patent with publication number CN108001286A discloses a power lithium battery active safety protection system, including a display screen for displaying lithium battery-related data information, information collection The module is electrically connected to the lithium battery to collect relevant parameters of the lithium battery and connected to the display screen through the CAN communication module. The data comparison center is used to set and store the preset standard lithium battery parameters. The data monitoring module is electrically connected to the data comparison The center and the information collection module are used to compare and monitor the lithium battery parameters collected by the information collection module with the data of the data center. The battery pack control module is electrically connected to the data monitoring module to monitor the lithium battery The abnormal parameters are controlled and adjusted, and its protective measures are perfect and comprehensive, and try to avoid affecting the efficient power supply of the connected equipment as much as possible, but there are still big problems in its protective effect, and it is not convenient to use.

[0003] During the use of the existing battery safety protection integrated system, there is a situation where the battery is prone to overheating and the battery explodes, and the voltage of the battery when it is powered and discharged is not monitored situation, it is easy to cause accidents due to voltage instability, and the existing battery safety protection integrated system is not convenient to use. In order to solve these defects, a solution is proposed
