A battery system and a method of determining whether a battery system arranged onto a vehicle is connected to an external battery charging unit, are disclosed. The battery system includes a plurality of battery cells, first and second main terminals connected to the battery cells, and a charging interface comprising first and second contact points connected to corresponding first and second main terminals, wherein the battery system is arranged onto a vehicle and configured to be connected via the first and second contact points to an external battery charging unit for charging of the battery system, wherein the battery system includes a switch arranged between the first main terminal and the corresponding first contact point so as to allow disconnection of the first contact point from the first main terminal, wherein the battery system is provided with a voltage measurement member arranged to measure a voltage between the first contact point and a reference point having a potential substantially similar to the disconnected first main terminal, wherein the battery system includes a battery management circuitry arranged to control the switch and to receive a signal from the voltage measurement member, wherein the battery management circuitry is configured to determine, by comparing a value from the voltage measurement to a threshold value, whether the charging unit is connected to the first and second contact points of the battery system.
