1. A cooling system for an enclosure containing a thermal mass, comprising:
- a cooling device;
a controller for controlling said cooling device;
a temperature sensor for measuring a temperature of the thermal mass, wherein said temperature sensor is connected to said controller; and
a time of day sensor connected to said controller;
wherein said controller controls said cooling device to cool the thermal mass to as desired temperature during off-peak hours in order to reduce the cost of operating said cooling system.

Abstract
A cooling system and method for an outdoor electronics enclosure includes an air conditioner controlled to operate during off-peak hours, so as to pre-cool batteries. The cooled batteries keep the enclosure cool during peak hours so that it is not necessary to run the air conditioner when electricity prices are at their peak. A clock or light sensor determines the time of day. A controller has stored data indicating the peak hours when electricity costs more.
