Abstract
A charging system for an energy storage in a vehicle comprising: a plurality of parallelly arranged charging switch units, each 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 flow of current from the charging port to the energy storage; for each charging switch unit, a measurement device configured to determine a parameter indicative of a resistance in a current path through the charging switch unit, and a variable resistor configured to control the resistance in the current path; and a charging control unit connected to each of the charging switch units and configured to, if an estimated difference in resistance between any two of the plurality of current paths through a charging switch unit is higher than a predetermined difference threshold value, control the variable resistor of a charging switch unit in the current path having the lowest resistance to increase the resistance of that current path.
