In 2021, BYD, Geely, Great Wall Motor, Xpeng Motors and Leapmotor among others have announced their 800V high voltage technology deployment plans Li Auto, NIO and the likes are preparing for related technologies as well. In the case of the same charging power, under the 800V fast charging architecture the high voltage wiring harness boasts smaller diameter and costs less, and the battery dissipates less heat, which makes thermal management easier and optimizes the overall cost of the battery.Īlready, most OEMs have made aggressive inroads into the 800V high voltage platform since it serves as an efficient solution to the replenishment anxiety. It is hard for a 400V platform to enable >200KW fast charge under current E/E architectures, while the upgrade to the 800V platform allows much smaller fast charging current at 200KW, making it more likely to achieve >350KW fast charge. Product Code: ZHP117 Research on 800V high voltage platform: the mass production will commence in 2022 800V high voltage platform-based models are a key deployment of OEMs.
