Leading automakers, such as Porsche and Audi, are readying production of high-end all-electric cars to meet demand for emerging mobility and car sharing applications.
However, the public charging infrastructure is not ready to charge car batteries with 300 kW of capacity in a reasonable amount of time, they say. Now, two suppliers say they have developed technologies to solve the problem.
Automotive suppliers ITT Cannon and Leoni recently said in separate announcements that their components can reduce the charging time of high-capacity batteries from several hours to just a few minutes.
Leoni's charging station concept, for example, can charge a Tesla S-caliber 85 kWh battery in 15 minutes or less. Similarly, ITT Cannon says its charger is designed to deliver up to 400 kW at 400 amps.
Both solutions rely on cooling technologies to ensure that their high-speed charging systems do not overheat.
