摘要:
An electrical power storage device provides power to crank an internal combustion engine. Thereafter available power from the electric power storage device to crank the engine again is continually updated. Remedial measures are invoked if the available power is less than a predetermined power threshold.

摘要:
A method and article of manufacture for monitoring an electrical energy storage device adapted to supply electrical power to a selectively actuable electric motor is described. This comprises determining a state of charge and a temperature of the electrical energy storage device subsequent to a stabilization period, and measuring a minimum voltage output from the electrical energy storage device during selective actuation of the electric motor. One of a plurality of predetermined threshold voltage states is selected based upon the state of charge and the temperature. The minimum voltage is compared to the selected predetermined threshold voltage.
