A temperature regulation system for use in an electric vehicle automatically provides for open-loop and closed-loop operation. In the closed-loop mode, air is forced through the electric motors of the vehicle, and is then delivered to selected components of the vehicle to keep them warm and dry. In the open-loop mode, outside air is allowed to enter the system to prevent overheating of critical components. The system is intended for use in an electric vehicle, such as a fork lift truck, which must alternate between operation in extremely cold environments and operation at normal temperatures. |
