Rawsun On Board Charger is mainly used for hybrid electric vehicles, full electric vehicles, electric buses, various electric logistics vehicles and other electric vehicles. It is suitable for on-board power battery charging such as lithium battery packs. Can work in the input of 100-240vac rated grid voltage, for different customer battery pack and special design of dc voltage output. Make the charger always work in the optimized conversion efficiency working range, greatly improve the product performance and high reliability.
The module is equipped with an advanced interleave APFC active power factor correction circuit, so that the utilization rate of electric energy during charging is close to 1 and the harmonic pollution to the common grid is reduced at the same time. Part of DCDC adopts novel full-bridge phase shift LLC resonant adaptive full-soft switch power conversion technology, which has features of efficiency and precision. Module protection function is perfect, with input overvoltage, undervoltage protection; Output overcurrent protection; Output overvoltage and undervoltage protection; Output short circuit protection, over temperature protection; It has intelligent design of high temperature and low voltage input.
The charger is equipped with CAN communication interface, which CAN communicate with BMS, and the charging voltage and current CAN be set by BMS, as well as the functions of switching the charger on and off.
