According to a report in Nikkei Asia, Daikin Industries, Japan’s top air conditioner maker, has developed a refrigerant for electric vehicles that can extend their range by up to 50%. The company plans to commercialize the product by 2025, the report said.
Daikin’s new refrigerant supposedly has a boiling point of about minus 40 °C, 10 to 15 degrees lower than the conventional product. That reduces the power required for compression.
Daikin believes that in an EV with the air conditioner running and operating in an urban area of Japan, a car with a range of 200 km on a full charge could travel an additional 100 km with the new refrigerant, according to the report.
The company has already developed the product, and U.S. industry group SAE International will verify its performance and safety under operating conditions.
Daikin—the world’s largest air conditioner manufacturer by sales and the leading producer of refrigerant—is not currently in the automotive market. The company has decided to enter the market with its new technology, anticipating that the supply chain will change dramatically with the shift to EVs.
