Abstract
Systems and methods of providing integrated battery protection for a plurality of series-connected batteries, in which a plurality of controllable switches are used to disconnect or otherwise isolate the respective batteries, substantially simultaneously, from an external circuit in response to certain fault or non-fault battery conditions. When the plurality of controllable switches are synchronously transitioned from a closed or 'ON' state to an opened or 'OFF' state, the voltages of the respective batteries become distributed among the controllable switches, allowing for the use of switches having a reduced voltage rating as well as a reduced cost. By connecting a balancing resistor across each of a plurality of series-connected battery/switch pairs, a more even distribution of the voltages of the respective batteries among the controllable switches can be achieved, providing the system with more predictable operation.
