Abstract

An example method includes intentionally precharging a powertrain of an electric vehicle for an first time period that is different than a second precharge time period. An example electric vehicle assembly includes a precharge contactor transitionable back and forth between an open state and a closed state, a first main contactor, a second main contactor, and a controller configured to selectively close the second main contactor after the precharge contactor has been closed for a first time period that is different than a second precharge time period.
