To reduce the concern of battery charging and a large amount of heat generated while charging electric vehicles at fast-charging stations BENTELER, climate-friendly high-pressure heat exchanger offers an innovative solution for effective and fast cooling.
The BENTELER high-pressure heat exchanger is installed, in the air conditioning circuit. Jens-Eike Jesau, the developer responsible, said: “Coupling battery cooling and air conditioning in this way increases the cooling power available during charging reducing the battery charging time.” On the one hand, the battery and car interior can be optimally cooled, while on the other hand, the battery heat can be used, to heat the passenger compartment when necessary.
The high-pressure heat exchanger from BENTELER uses CO2 as the cooling medium. The natural refrigerant with the designation R744 is liquefied before entering the cooler. There it evaporates and absorbs the waste heat from the battery charging process. The completely sealed system avoids CO2 from escaping. The cooling capacity of the climate-friendly solution from BENTELER is significantly higher compared to conventional heat exchangers. Lübbers said: “We are proud to be able to offer this new solution to our e-mobility customers. Backed up by our systems expertise as one of the leading global partners to the automotive industry.”
