Introduction to Vehicle Upgrade Methods to Meet Supercharging Needs

In the recharging mode, there are also some strict requirements for the car. In terms of vehicle components, the battery voltage of the car has increased from 450V to 950V or higher, and the charging and distribution system, electric drive system, battery system and thermal management system have all undergone significant changes.
High voltage will increase the cost of compressors, PTCs and engine control microcontrollers. Compared with the more mature 2C and 400V fast charging systems, the cost of the 950V platform increases by about 6,500 yuan compared with the 450V platform. In the future, domestic and foreign automakers will give preference to the application costa rica number data of high-voltage platforms of 800V and above in mid- and high-end models to create differentiated competitiveness. In the long term, as the cost of key components such as SiC and fast charging batteries decreases, mid- and low-end models will also have demand for fast charging, and there is a long-term trend towards upgrading electrical architectures to 800V and beyond.
Compared with the 450V platform, under the same battery capacity, the 950V platform is achieved by increasing the number of battery cells in series and reducing the capacity of a single battery cell. The number of batteries in series increases.
