An off-board battery cycler is used to condition an on-board battery system used in electric or hybrid electric vehicles. The battery cycler periodically discharges the vehicle's high voltage traction battery to eliminate battery “memory” that can prevent the battery from being fully charged. The cycler also recharges both the high voltage battery and an on-board low voltage battery used to power the vehicle's electrical system. High voltage AC power used in recharging the high voltage battery is switched using contactors physically isolated within the battery cycler, in order to protect operating personnel from coming onto contact with high voltage. Faults and malfunctions are recorded by the vehicle's on-board controller
Apparatus for controlling the charge on a battery system for a vehicle, the battery system including a first, low voltage battery for operating electrical systems on the vehicle and a second, high voltage traction battery, comprising:
A battery charge control system for vehicles, comprising:
A system for controlling the state of charge of an on-board battery system for a vehicle, wherein the battery system includes a low voltage battery for operating electrical systems on the vehicle and a high voltage traction battery, comprising:
