Air-based thermal conditioning system for a hybrid battery

Thermal conditioning system for the energy storage system of a hybrid vehicle. At least one additional air source other than a permanently open air source has a selectively operable Aktuatorklappe which connects the auxiliary air source either to the energy storage system blower or separates therefrom, whereby the air flow is selected to condition the energy storage system temperature technically optimal. The additional air source preferably comprises the HVAC ducting.
