A method of determining remaining charge time in a rechargeable energy storage system (RESS) of an electric vehicle (EV) having an auxiliary system includes determining available amount of energy in the RESS when the EV is stationary. The method also includes determining amounts of RESS energy and time required to achieve auxiliary system steady state operation and remaining RESS energy to maintain auxiliary system steady state operation after the steady state is achieved. The method additionally includes determining time left for maintaining the steady state operation based on the amount of remaining RESS energy and RESS power consumption required for maintaining the steady state operation. Furthermore, the method includes determining the remaining RESS charge time based on time to achieve and amount of time left to maintain the steady state operation and triggering a signal indicative of the remaining charge time.
