Estimation of remaining battery charge time in stationary electric vehicle

Estimation of remaining battery charge time in a stationary electric vehicle is provided. 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 an available amount of energy in the RESS when the EV is stationary. The method also includes determining an amount of RESS energy and time required to achieve the steady state operation of the auxiliary system, and an amount of remaining RESS energy to maintain the steady state operation of the auxiliary system after achieving the steady state. The method additionally includes determining a remaining time to maintain the steady-state operation based on the amount of remaining RESS energy and the RESS power consumption required to maintain the steady-state operation. Further, the method includes determining a remaining RESS charge time based on the time to implement the steady-state operation and the remaining amount of time to maintain the steady-state o
