The battery (64) includes a plurality of battery strings (72). The at least one charger contactor (106, 132, 142) includes a first gate (138, 148) and a second gate (140, 150). The at least one charger contactor (106, 132, 142) is operable to a closed position with a first control signal present at the first gate (138, 148) and a second control signal present at the second gate (140, 150). The at least one charger contactor (106, 132, 142) is operable to an open position with one or both of the first control signal absent at the first gate (138, 148) or the second control signal absent at the second gate (140, 150). The first control channel (110, 114) is operable to selectively apply the first control signal to the first gate (138, 148). The second control channel (112, 116) is operable to selectively apply the second control signal to the second gate (140, 150).",
