    Abstract: An apparatus is provided for charging a first storage battery and a second storage battery electrically connected together in series includes a first Kelvin connection, a second Kelvin connection and a third Kelvin connection coupled to the storage batteries. At least two of the Kelvin connections are configured to charge at least one of the first and second batteries. A charging source configured to selectively couple a charge signal to a storage battery through the Kelvin connections. A switching device selectively couples the charging source and measurement circuitry to at least two of the first, second and third Kelvin connections. A microprocessor selectively controls the switching device, charges the batteries, and measures a parameter of the batteries as a function of the charging signal applied to the batteries.

    IPC: B60L53/20

    Abstract: A maintenance device for coupling to electrical circuitry of an electric vehicle for testing the low voltage battery system of the electric vehicle includes electrical connectors to configured to couple to terminals of a low voltage battery of the low voltage battery system of the vehicle and electrically couple to a DC-to-DC convertor of the vehicle which is used to charge the low voltage battery. Measurement circuitry couples to the electrical connectors. A controller coupled to the measurement circuitry is configured to measure a parameter of the low voltage battery and a parameter of the DC-to-DC convertor and responsively determine a condition of the low voltage battery and the DC-to-DC convertor.
