Analysis of New Technology Development and Social Application of DC Charging System

Wu Hanhui，Zhang Zonghao

Abstract：With the rapid development of new energy vehicles in recent years， most OEMs have made a lot of changes in topology based on national standards. For example， the battery temperature control system will be added， the booster system will be added， and the vehicle-end charging contactor will be reduced. Taking the DC charging system as the object， the article introduces the changes brought by the new technology to the system and the charging adaptability problems derived from it， and provides a practical solution to the problems.

Key words：charging system， new technology， failure analysis， boost charging system
