Abstract
In a method of determining whether a battery system arranged onto a vehicle is connected to an external battery charging unit, the battery system includes a plurality of battery cells, first and second main terminals connected to the battery cells, and a charging interface including first and second contact points connected to corresponding first and second main terminals. The charging unit includes third and fourth contact points configured to be connected to the first and second contact points during charging of the battery system. The method includes disconnecting, by means of a switch, the first main terminal from the corresponding first contact point; measuring a voltage between the first contact point and a reference point having a potential substantially similar to the disconnected first main terminal; and determining, by comparing a value from the voltage measurement to a threshold value, whether the charging unit is connected to the battery system.
