Method for operation of lithium ion battery of motor vehicle, involves fluidically connecting inner space of battery with refrigerant circuit of battery by emergency line, and guiding refrigerant from refrigerant circuit into inner space

摘要

The method involves fluidically connecting an inner space (3) of a battery (1) with a refrigerant circuit (6) of the battery by an emergency line (4), where the inner space comprises single cells (2) for fire prevention and/or fire fighting. A refrigerant is temporarily guided from the refrigerant circuit into the inner space. The inner space is fluidically integrated into a refrigerant line system of an air conditioning circuit of a vehicle. A non-combustible liquid or gaseous fluid i.e. carbon dioxide, is selected as the refrigerant of the air conditioning circuit. An independent claim is also included for a device for operation of a fire-endangered battery within an air-conditioned vehicle i.e. motor vehicle.
