NOVELTY - The BCM (16) includes a microprocessor (17) for controlling a number of switches, has connections across and therefore can measure the voltage across each of the batteries (10A-10D). When switches (22A-22D/24A-24D) are closed, each capacitor (18A-18D) is placed in parallel with a respective battery and when switches (26A-26D/28A-28D) are closed, the capacitors are coupled in parallel with each other.    USE - For balancing the charges of a number of batteries for e.g. in an electric vehicle.    ADVANTAGE - Substantially reduces or avoids the need to provide charge currents to fully charged batteries. Charging can be performed energy efficiently and without generating substantial heat and does not have an adverse impact on the battery charging times. Does not depend on the vehicle being 'on charge' until all the batteries are fully charged for charge balancing to be performed, and does not discharge the battery immediately before charging.    DETAILED DESCRIPTION - With the capacitors in an uncharged state, switches (22A-22D/24A-24D) are closed, with switches (26A-26D/28A-28D) open. The capacitors are thus placed across a respective battery, therefore each capacitor will charge through its respective resistor (20A-20D) to the voltage of the respective battery. After providing sufficient time (i.e. several R-C time constants) for the capacitors to charge, switches (22A-22D/24A-24D) are opened. Switches (26A-26D/28A-28D) are then closed, placing the capacitors in parallel with each other and after a sufficient time, their charges will equalize through the resistors and the switches are then open. Switches (22A-22D/24A-24D) are then closed and with the capacitors having equal voltages (average voltages of the batteries), the capacitors will tend to equalize the voltages of the batteries. The switching sequence may be repeated at a predetermined rate, or may begin and repeated only when the BCM senses a charge imbalance of a particular severity among the batteries. Also, battery charging may be performed when the batteries are being charged from an external charger, when they are discharging to provide power to a motor, and/or when the batteries are quiescent (i.e. neither charging or discharging). INDEPENDENT CLAIMS are also included for the following:    (1) a system for balancing charge and    (2) a battery balancing charging system.
