Embodiment Construction

[0027] figure 1 An exemplary embodiment of a motor vehicle 1 is shown with a cooling device for a battery module 2 . In addition to cooling by means of the conventional ventilation system 3 with blower 4 , the battery modules 2 can also be cooled with compressed air. In this case, valve 7 is opened by control unit 8 and compressed air is supplied from pressure accumulator 9 to battery module 2 . A throttle 10 is also provided between the pressure accumulator 9 and the battery module 2 . This restrictor restricts gas flow. As a result, gas expansion and thus cooling takes place in the subsequent line. The gas is fed to the battery module 2 at excess pressure, flows through it and is released again into the environment at the exhaust port 6 . The pressure accumulator 9 is part of the air spring system. The pressure accumulator is connected via a valve 12 to the pneumatics 13 of the air spring system. The pneumatic device 13 of the air spring system can supply compressed ai...

Abstract

Motor vehicle comprising at least one battery module (2) with a cooling device, the cooling device having an accumulator (9) for compressed gas that can be fed to the battery module (2) for cooling.

Description

technical field [0001] The invention relates to a motor vehicle comprising at least one battery module with a cooling device. Background technique [0002] First of all, from an environmental point of view, electric vehicles are becoming more and more important. While pure electric vehicles still play a subordinate role and are mainly suitable for urban traffic, hybrid vehicles, especially mild hybrid vehicles, are becoming more and more popular. [0003] A conventional hybrid vehicle uses an internal combustion engine and an electric motor. In mild hybrid vehicles, the electric drive components play an auxiliary role, that is, they serve to boost the vehicle's power. In addition, fuel is saved especially when starting or accelerating. In this case, the battery is primarily charged by recuperated energy, for example as a result of braking. [0004] It is in the case of mild hybridization that the battery can be charged and discharged very quickly. Since each battery has...
