Embodiment

[0036] A method of using an active safety protection system for a power lithium battery is as follows:

[0037] S1. The data acquisition module in the lithium battery safety protection system collects the voltage data, current data and temperature data information of the lithium battery pack, and compares the collected voltage, current and temperature data with the data comparison module through the central processing unit;

[0038]S2. If there is a problem with the collected voltage, current or temperature data, the central processor passes through the voltage regulation module, current control module and temperature regulation module in the lithium battery pack control module respectively through the voltage regulation device, the current balance control device and the heating refrigerator Carry out corresponding adjustment and control on the lithium battery pack; among them, the central processor performs power-off protection on the lithium battery pack through the power-off...
