Abstract
A battery control system includes T contactor paths connected in parallel between a battery and a load, where T is an integer greater than one. Each of the T contactor paths includes a first contactor and a second contactor connected in series with the first contactor. Each of the T contactor paths includes at least one of a first voltage sensor configured to sense a first voltage between the first contactor and the second contactor; and a current sensor configured to sense current flowing through the first contactor and the second contactor. A second voltage sensor is configured to sense a second voltage at one end of the T contactor paths. A third voltage sensor is configured to sense a third voltage at an opposite end of the T contactor paths.
