Embodiment 1
[0057] An embodiment of the present invention provides a method for discharging waste battery cells, the method comprising:
[0058] S1) Obtain the cell voltage, select a monitoring circuit and obtain the working voltage range of the monitoring circuit;
[0059]S2) Determine an energy-consuming circuit that matches the voltage of the cell, use the energy-consuming circuit to reduce the voltage of the cell to a preset scrapping threshold voltage, and use the voltage of the cell to obtain a voltage that belongs to the working voltage range monitoring voltage, driving the monitoring circuit into a working state through the monitoring voltage, wherein the working state is used to identify the change of the cell voltage relative to the preset scrapping threshold voltage;
[0060] Different from the voltage of the external load circuit, the cell voltage is short-term (the cell voltage is the embodiment of the energy of the cell, and it takes a certain amount of time to release the e...
