International Classification:

B60L 11/18
H02J 7/00

Abstract:

A vehicle includes a thermal system for a battery; and a controller for the thermal system. The controller may be configured to, during vehicle motion, cool the battery when a temperature of the battery exceeds a lower threshold and inhibit transfer of power with the battery when the temperature exceeds an upper threshold, and while coupled with a charge station, heat the battery to a temperature between the lower threshold and the upper threshold.

Abstract:

A battery management system for a vehicle includes a controller configured to, in response to a rate of change of voltage during discharge of a battery cell exceeding a first threshold more than a predetermined number of times over a predefined duration, output an error signal, and in response to the rate of change exceeding a second threshold greater than the first, output the error signal.
