Abstract
A method and apparatus for controlling the temperature of a battery during discharge cycles. Battery temperature is reported to a controller that returns a shunt current indicator. Heat is generated as the battery is discharged according to the shunt current indicator. This heat is then applied to the terminal of a battery.
