Abstract: A power management system for a vehicle having at least one motor, comprising a user interface, a global positioning system input, an energy management system input, a motor controller operatively connected to the at least one motor and a power controller operatively connected to the user interface, the global positioning system input, the energy management system input and the motor controller, the power controller being configured to estimate a maximum available power value based on information provided by the user interface, the global positioning system input and the energy management system input. The power controller limits power available to the motor though the motor controller based on the estimated maximum available power.
