A power management system is disclosed for an electrically driven vehicle, comprising a powertrain of at least two electric motors that can be selectively geared into the powertrain. The power management system is configured to indicate a level of mechanical power demanded from the powertrain, to estimate an electrical power demand from a respective one of the at least two electric motors as a function of the demanded mechanical power, and to activate or deactivate the respective electric motor in response to the mechanical power demand indicator. The power management system is further configured to (a) deactivate the respective electric motor when (1) the demanded mechanical power does not exceed a maximum value with the respective electric motor deactivated, and (2) the estimated electric power with the respective electric motor deactivated is lower than that with the respective electric motor activated; or otherwise (b) activate the respective electric motor.

Power management system for electrical vehicles with multiple motors

Systems and methods for managing or controlling an automatic engine restart system of a vehicle are provided herein. The method is operative to disable automatic engine restarts during specified restart inhibit periods to improve the comfort of the operator of the vehicle and others near the vehicle (e.g., during hoteling) or to satisfy regulations (e.g. silent area or green zone). During times outside of the specified restart inhibit periods, the method may control the automatic restarts to provide a determined level of charge for a rechargeable electrical energy source (e.g., battery) of the vehicle at a time just prior to the restart inhibit period so that the electrical energy source will be able to power various loads for an extended time during the restart inhibit period. The system includes a local or remote user interface that allows various parameters to be programmed. The system may also include an energy management system that optimizes the automatic restarts to achieve various goals.
