Abstract: A device and a method establish an electrical connection between an electrical traction energy storage system and a high-voltage on-board electrical system for a motor vehicle. The device includes a housing, and a battery junction box assembly connected or connectable to the housing using a first detachable connection. The battery junction box assembly includes a switching device and a touch protection cover. The switching device is arranged on a carrier plate and selectively establishes or disconnects an electrical connection between a first terminal for connecting the electrical traction energy storage system and a second terminal for connecting the high-voltage on-board electrical system. The touch protection cover is configured as a cover for the switching device and is connected or may be connected to the carrier plate using a second detachable connection. The second detachable connection is arranged such that it is not accessible in an assembled state of the device.

Abstract: An apparatus is described for heating oil for an internal-combustion engine. The apparatus includes a heat-exchanger arranged within an oil sump of the internal-combustion engine, which is flowed through or capable of being flowed through by a thermal medium for the purpose of emitting heat to oil in the oil sump. The apparatus further includes a heat-source in fluidic communication with the heat-exchanger, which is designed to heat the thermal medium outside the oil sump and outside the internal-combustion engine.
