1. A method of managing energy for a vehicle having a battery and a motor, the method comprising:
- generating electrical energy through the use of the motor;
determining a battery temperature, a battery charge limit and a total regenerative energy available; and
applying electrical energy from the motor to the battery to simultaneously charge and heat the battery when the total regenerative energy available is greater than the battery charge limit and the battery temperature is greater than a lower charge efficiency temperature.

Abstract
A system and method for efficient management of energy within a vehicle wherein the vehicle includes a battery and a motor. The method comprises generating electrical energy through the use of the motor and determining the battery temperature and the battery'"'"'s state of charge. The method further includes applying electrical energy from the motor to the battery to simultaneously charge and heat the battery when the battery'"'"'s state of charge is less than a predetermined battery charge limit and the battery temperature is greater than a lower charge efficiency temperature.

15. A method of managing energy for a vehicle having an energy management device that is configured to determine the battery temperature, battery charge limit and total regenerative energy available, a battery, and a motor comprising:
-
determining the battery temperature and battery state of charge;
receiving an input torque at the motor;
transforming the input torque into electrical energy through the use of the motor; and
applying electrical energy from the motor to the battery through the use of the energy management device for simultaneous charging and heating of the battery when the total regenerative energy available is greater than the battery charge limit and the battery temperature is greater than a lower charge efficiency temperature but less than an upper charge efficiency temperature. - View Dependent Claims (16, 17, 18, 19, 20)
