The component makes EVs more suitable for everyday use and the mass market, while keeping the battery protected against excessive temperatures
Mahle has developed a new type of condenser that has been designed specifically for hybrid and electric vehicles (EV) that helps to accelerate traction battery charging. This new design offers significantly higher power density than the current one, the company noted. As part of the cooling system, the condenser is a component that ensures the battery is optimally cooled during fast charging and reliably protected against damage. The new Ozonepro condenser is also said to provide sufficient cooling capacity for comfortable temperature in the cabin without taking up additional installation space.
Since fast charging is a key factor in the acceptance of EVs, this innovation contributes toward making this form of transport more suitable for everyday use and the mass market, Mahle said. Alongside the component design, the production process has also been optimised to provide a lighter product that is less susceptible to corrosion and requires lesser refrigerant, it explained.
The most critical task of the engine cooling system has been to protect the combustion engine from overheating under high loads. However, thermal management of EVs has become much more complex including stronger interactions between cabin and powertrain thermal management and the need to maintain components like battery within tightly defined temperature limits. Mahle has responded with a large number of innovations for the thermal management of electrically-powered vehicles, thus enabling the success of new forms of mobility.
Laurent Art, Director, Advanced Engineering, Thermal Management, Mahle, said battery cooling is crucial for the performance of EVs. In developing the new condenser, Mahle was able to draw on its many years of expertise in thermal management, he added. Art noted that that the company is confident that this condenser will give a further boost to the development of EVs.
