The self-contained EPU™ operates stand-alone without any support from the simi-truck. The EPU™ deliveries hot or cold air into the sleeper cab when the truck engine is turned off. (During resting, loading and unloading periods.) When the truck engine is running, the EPU™ charges and operates from the truck's battery pack. Thus the EPU™ can assist the main AC while driving if needed.
