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.
A method of charging an electric storage battery by an actuatable, electrical supply located in or near a charging unit, said battery having a heat responsive characteristic to be controlled in accordance with a time-based temperature relationship at a given area of said battery by circulating a liquid through said battery and at said area and controlling the temperature of said liquid in accordance with said time-based relationship, said battery being mounted on an electric powered motor vehicle for driving said vehicle and having charging terminals, said method comprising the steps of:
A method of providing a cooling liquid to the cooling heat exchanger at a given area of a storage battery mounted on a vehicle for driving said vehicle, said liquid being at an inlet temperature which varies in a time-based relationship and being obtained from said battery heat exchanger at a temperature greater than said inlet temperature, said method comprising the steps of:
An apparatus for charging an electric storage battery by an actuatable, electrical power supply located in or near a charging unit, said battery having a heat responsive characteristic to be controlled in accordance with a time-based temperature relationship at a give area of said battery by circulating a liquid through said battery and at said area and controlling the temperature of said liquid in accordance with said time-based relationship, said battery being mounted on an electric powered motor vehicle for driving said vehicle and having charging terminals, said apparatus comprising the following:
An apparatus for providing a cooling liquid to the cooling heat exchanger at a given area of a storage battery mounted on a vehicle for driving said vehicle, said liquid being at an inlet temperature which varies in a time-based relationship and being obtained from said battery heat exchanger at a temperature greater than said inlet temperature, said apparatus comprising:
