High precision capacity sorting tester for lithium battery step utilization

Function of dividing cabinet：

In the lithium-ion battery production process, there is a work station is capacity separation, in short, the battery capacity sorting. What is the capacity of the battery is involved here. The actual capacity usually depends on the time when the battery voltage is electrostatic from 4.2V to 3.0V with the current of 1c5 (5 as the superscript). C5 (5 is the superscript) responds to the nominal capacity (or rated capacity) of the battery. This capacity corresponds to the capacity registered or marked by the battery, which refers to the cell or battery at the ambient temperature of 23 ℃ ± 2 The amount of electricity obtained by a cell or battery at a rate of 5 h (0.2ita) to the cut-off voltage. Capacity division is a process of testing the actual capacity of the battery. Unlike the battery, the process with static electricity depends on the actual capacity of the battery. The electrostatic time of 1c5 (5 as superscript) a rejected in GB / t18287-2000 is no more than 51min. However, the industry usually takes 60 minutes as the lower level of rejection.

Batteries can not be used only by capacity division. In the whole production process, when the battery reaches the capacity division position, it has been basically produced and can also be used. The capacity division is only to test the actual capacity of the battery.
