ABSTRACT:
A method and apparatus for providing a cooling liquid to the heat exchanger in a storage battery mounted on a vehicle for driving the vehicle, wherein the liquid is to be supplied to the battery at an inlet temperature which varies in a time-based relationship. The liquid to be cooled is obtained from the battery itself in a recirculative system located generally outside the vehicle. In accordance with this method and apparatus, the liquid returned from the vehicle mounted storage battery is divided into first and second portions, the first of these portions is cooled at a preselected cooling rate, thereafter, the cooled first portion and the uncooled or bypassed second portion are recombined to provide the liquid supplied to the battery heat exchanger. The ratio of the first and second portions is adjusted in accordance with a time-based relationship wherein the temperature within the battery is intentionally changed during a charging cycle.
