Stackable bi-directional multicell battery balancer |
摘要 |
<p>A battery balancing system includes at least one sub-stack, each sub-stack comprising a plurality of cells connected in series. The system also includes a balancing module for each sub-stack comprising an independent bidirectional balancer for each cell in the sub-stack. The system includes a daisy chained stackable serial port. The balancing system senses a state of charge (SOC) of each cell in each sub-stack. The average SOC of the sub-stack is determined. For a weak cell, additional charge is provided from its respective sub-stack during the discharging of the battery. For a strong cell, additional charge is removed and provided to its respective sub-stack during discharging of the battery. Any number of sub-stacks can be stacked in series while maintaining the same serial control, allowing a theoretically unlimited number of cells to be supported from a single communication port without the need for additional digital isolators.</p> |
