BMW AG says next-generation fast-charging systems for electric vehicles will require new cooling methods to tackle higher heat dissipation demand without increasing noise levels.
As a result, the carmaker is asking potential partners to submit proposals to develop alternatives to current electric refrigerant compressors. BMW is looking for a solution that has an operating noise level below 35 dB.
Fast charging creates additional heat, which needs to be quickly dissipated. But BMW says that simply boosting cooling capacities would generate “significantly higher” vibrations through fans and other moving components. This, in turn, would require sophisticated damping to offset the increased noise.
Among the cooling technologies BMW says it will consider are absorption, electrochemical, innovative compression methods, magnetocaloric, Schukey machine applications, thermoacoustic and the use of phase change (vapor) materials. The heat flux to ambient air must be part of the system.
