| Summary: | The present invention provides an energy storage system comprising at least one voltage source, and a string of series connected cells, wherein each of the cells is connected to a circuit, wherein the circuit comprises at least one voltage reference, at least one voltage divider, which sets a trip point, and at least one operational amplifier, wherein at least one operational amplifier receives a first input from voltage reference and a second input from voltage divider and shunts an output through a power dissipative device when voltage of a cell exceeds said trip point. |
