CHARGING SYSTEM FOR A VEHICLE AND A METHOD FOR CONTROLLING THE CHARGING SYSTEM

A charging system for an energy storage in a vehicle comprising: a plurality of parallelly arranged charging switch units, each charging switch unit having an input terminal configured to be connected to a common charging port, and an output terminal configured to be connected to the energy storage, wherein each charging switch unit comprises a contactor configured to control a current flow from the charging port to the energy storage; at least one current meter configured to determine a current flowing through each charging switch unit; at least one temperature sensing unit configured to determine a temperature of each charging switch unit; and a charging control unit connected to each of the charging switch units and configured to: if a difference in temperature and/or current between any two of the plurality of charging switch units exceed a predetermined difference threshold value, and if a current in any of the charging switch units exceeds a predetermined current threshold value, control the charging system to reduce the temperature of the charging switch unit having the highest temperature.
