Abstract:
1. A battery system comprising: a first system terminal; a second system terminal; a plurality of rechargeable batteries coupled with the first and second system terminals and configured to supply electrical energy to a load coupled with the first and second system terminals and to receive electrical energy from a charger coupled with the first and second system terminals to charge the rechargeable batteries; and control circuitry configured to monitor individual ones of the rechargeable batteries and to control an amount of electrical energy supplied to at least one of the rechargeable batteries using the monitoring; wherein the rechargeable batteries individually comprise switching circuitry coupled between at least one of the first and second system terminals and the rechargeable cells of the respective individual battery, and wherein the control circuitry is configured to control the switching circuitry of the at least one of the rechargeable batteries to control the amount of electrical energy supplied to the at least one of the rechargeable batteries; and wherein the control circuitry is further configured to control the switching circuitry of another of the rechargeable batteries to electrically isolate the another of the rechargeable batteries from at least one of the first and second system terminals while the control circuitry is configured to control the switching circuitry of the at least one of the rechargeable batteries to electrically couple the at least one of the rechargeable batteries to the first and second system terminals.
