Changan electric vehicles if there is no fast charging function, under normal circumstances can not be directly installed fast charging.
Fast charging requires special battery management systems and power equipment support, but also requires specially designed charging interfaces and lines to withstand the high-power charging process. If the original electric vehicle only supports the slow charge function, then its battery management system and power supply equipment do not have the support ability of fast charge, and the interface and line are not enough to withstand the high-power charging process, so it can not be directly installed fast charge.
Changan new energy vehicles originally did not have fast charging function, it can not be installed later.
Because of the voltage and capacity of the battery, the later installation is very bad for the use of the car.
The first is because the voltage of the fast charge is very high, and the capacity of our vehicle power battery is so high.
The second is that the vehicle's electronic control management system does not have this function.
The third is the harness interface and the vehicle controller, the software and hardware do not have fast charge. So it's like getting a new car. It's cheap and hard to add.
