System and process for managing the temperature of rechargeable vehicle batteries

A process for managing the temperature of rechargeable vehicle batteries, comprising the steps of:

• providing an alternate power unit comprised of rechargeable batteries disposed within a housing;
• passing a refrigerant from a low pressure line of an air conditioning compressor of the vehicle through an evaporator associated with the housing;
• detecting a temperature of an interior of the housing;
• passing air through the evaporator to cool the air and directing the cooled air into the housing to cool the batteries when the detected temperature is above a predetermined temperature;
• and
• heating the interior of the housing when the detected temperature is below a predetermined temperature.
