Methods and systems are described to control the use of electrical power when charging a traction battery. A vehicle module can drive the contactor coils with two set-points for controlling the power into the contactor coils, namely, a travel or vehicle “on” set point and a charging, vehicle “off” set point. In use, full power is initially applied to the coils to guarantee immediate closure of the contactor. During charging and after closing the contactor, the power is set at the charging, vehicle “off” set point. The travel or vehicle “on” set point is higher than the charging, vehicle “off” set point. Using the charging, vehicle “off” set point reduces electricity consumption. The vehicle “on” set point is at a higher electrical level as it must maintain closure under worst-case vibration and shock conditions considering mounting location, contactor orientation, as well as other characteristics of the vehicle and contactor.
