program overview

the on-board charger is built in the new energy vehicle, which is used to charge the on-board high-voltage battery from the ac grid when parking. the battery used is usually more than 400v, and is developing towards higher voltage and higher number of battery strings. in order to realize a faster and lighter vehicle charging scheme, the new trend of charging power is upgraded from 6.6kw to 11kw. generally, the current flows from the grid to the battery in one direction, but there are also two-way flow design schemes. nano chip micro provides complete solutions for isolation voltage, isolation current detection, isolation drive and isolation communication, helping customers achieve higher power density obc solutions.
