Motor vehicle with battery cooling system

摘要

A motor vehicle includes at least one battery module configured to be cooled by compressed gas. The battery module has a cooling system which has an accumulator for compressed gas that can be fed to the battery module for cooling. A control device controls supply of gas from the accumulator to the battery module in dependency of at least one output value from at least one sensor configured to measure a current output from the battery module.

1. A motor vehicle comprising:
at least one battery module configured to be cooled by compressed gas supplied at a volume flow rate of one liter per second, a cooling system comprising a pressure accumulator for the compressed gas to be supplied to the battery module, at least one sensor configured to measure a current output from the battery module, a control device configured to control supply of cooling gas from the pressure accumulator to the battery module in dependency of at least one output value from the at least one sensor commensurate with the measured current output, and a passive cooling element arranged on a supply line of the compressed gas to the pressure accumulator and on the pressure accumulator.
