The EVL2642-R-00A is an evaluation board designed for applications using four MP2642 active balancers that are actively balancing five Li-ion battery cells. The MP2642 is a highly integrated, bidirectional active balancer that enables high-current charge redistribution between two series cells within a battery pack, while minimizing energy loss and heat. For large battery systems, active balancers can dramatically speed up the balancing process with high efficiency and allow for capacity recovery in stacks of mismatched batteries.

Each individual MP2642 device can be controlled to move charge between two battery cells. In buck-balancing mode, the MP2642 transfers charge from the upper cell to the lower cell, and in boost-balancing mode, the MP2642 transfers charge from the lower cell to the upper cell. Each MP2642 device can support up to 1A of net balancing current.

By interleaving multiple MP2642 devices across groups of cells and controlling the mode of each device, charge can be transferred to or from a target cell to the other four battery cells.

To guarantee safe operation, the MP2642 evaluation board has cell over-voltage protection (OVP), under-voltage protection (UVP), and thermal shutdown protection.
