Temperature maintained battery system
A chassis contains a battery charger connected to a multi-cell battery. The charger receives direct current from an external direct current power source and has means to automatically selectively charge the battery in accordance with a preselected charging program relating to temperature adjusted state of discharge of the battery. A heater device is positioned within the chassis which includes heater elements and a thermal switch which activates the heater elements to maintain the battery above a certain predetermined temperature in accordance with preselected temperature conditions occurring within the chassis. A cooling device within the chassis includes a cooler regulator, a temperature sensor, and peltier effect cooler elements. The cooler regulator activates and deactivates the peltier cooler elements in accordance with preselected temperature conditions within the chassis sensed by the temperature sensor. Various vehicle function circuitry may also be positioned within the chassis. The contents of the chassis are positioned to form a passage proximate the battery in communication with an inlet and outlet in the chassis to receive air for cooling purposes from an external source.
