Energy Storage: Multi-battery Charge Equalization Circuits

A battery charge equalizer provides individual cell charging in multi-cell battery strings in order to maintain all the cells at the same charge. Keeping all the cells in a multi-cell string at the same charge state maximizes the battery's life and performance. Equalization techniques require electrical circuitry to achieve cell monitoring and balancing.
