DEVICE FOR THE FILLING AND MAINTENANCE OF A SYSTEM WITH A BATTERY

A device for filling and maintenance of a system with a battery that is cooled by a coolant is disclosed. The device includes a control arrangement that, for a first filling of the system with the coolant: checks a system path for leakages via a leakage-checking arrangement; in the absence of leakage, fills the system with coolant via a coolant reservoir; flushes the system with coolant such that the coolant circulates along the system path through the system and the device; checks a quality of the coolant via an analysis arrangement during flushing, and cleans the coolant via a cleaning arrangement; and completes the first filling when the quality lies above a predetermined value range.
