Zusammenfassung:A system including a power tool and an energy supply device, wherein the energy supply device is provided for supplying the power tool with electrical energy. The energy supply device can be releasably connected to the power tool via an interface, wherein the interface comprises at least a female contact partner and a male contact partner. The interface has a total electrical transition resistance per pole of less than 0.4 milliohm, preferably less than 0.3 milliohm and particularly preferably less than 0.2 milliohm. At least one of the contact partners has a first coating, wherein the first coating has a graphite proportion of less than 30%. In addition, the interface may comprise more than six, preferably more than eight and most preferably more than twelve individual contact points. An energy supply device for use in the system is also provided.
