Summary
Starting with the bZ4X that went in to production in November 2023, Toyota has changed the thermal management design to improve the battery's low-temperature charging performance. It has been announced that the effect is that charging time at -10°C using a 90kW fast charger has been shortened by approximately 25 minutes (when charging from SOC 10 to 80%). The concept has already been adopted in the Toyota bZ3 battery electric compact sedan, an BEV jointly developed by Toyota, BYD Auto and FAW Toyota through the BYD Toyota EV Technology (BTET) joint venture, and Toyota is now working to bring this optimal technology closer to the global market.
To review the trends in these systems, this report compares the configuration and operation of thermal management systems, including the unique configurations of Tesla, Inc. (Tesla) and Hyundai Motor Company (Hyundai).
