The battery pack increases the output voltage by connecting cells in series. However, the voltage of each cell string may not be consistent when fully charged after using the battery pack for a period of time or a certain number of times. This would cause the battery cell to age rapidly, affecting the battery pack's storage capacity and life. Chroma’s battery module balancing system can detect the cell capacity and DCIR, and then restore the voltage consistency of each string by charging and discharging it, which could recover the battery pack storage capacity and prolong its life.

Constant current is used to load the battery cell for discharge and starts timing to calculate the availability of capacity.

It calculates the DCIR by the voltage and current of two loads.

The charge and discharge control is used to restore the voltage of each cell to the specified level. It can monitor the voltage and current of the DUT from time to time, also set the protection voltage to link with the security system in backstage.

Other customized features, such as: statistics test data for MES system.
