A temperature control device for temperature control of an electrical energy store for a motor vehicle includes a feed line element which is flushable by a temperature control fluid for the temperature control of the energy store, and which constitutes a first line element via which the temperature control fluid flowing in the feed line element can be admitted to the energy store, and includes a return line element which is flushable by the temperature control fluid, and which constitutes a second line element via which temperature control fluid flowing in the energy store can be evacuated from the energy store. The line elements are arranged in a housing which is common to the line elements, in which a housing bypass line element which is fluidically connected or connectable to the line elements is arranged, by way of which the energy store can be bypassed by the temperature control fluid.

An HV battery arrangement with a first HV battery unit that can be electrically coupled to a first HV onboard network part having a first drive unit of the motor vehicle, and with a second HV battery unit that can be electrically coupled to a second HV onboard network part having a second drive unit of the motor vehicle, wherein, between the first HV battery unit and the second HV battery unit, a switching device is arranged, by which the first and the second HV battery units can be connected in series and can be electrically disconnected from each other. The HV battery arrangement further has a control unit for actuating at least the switching device.

A high-voltage battery for a motor vehicle having at least one storage element for electrical energy, at least one control unit operating at a voltage lower than the high voltage. A modular unit including at least one switching mechanism and/or at least one fuse as electrical components, wherein the modular unit is attached in a pre-determined position to a housing, externally to this housing that holds the storage element and the control unit, in such a way that when the modular unit is plugged in on the housing, at least two high-voltage contacts of the modular unit, which are connected to at least one of the electrical components of the modular unit, are connected in an electrically conducting manner to assigned high-voltage contacts on the housing side, and at least one contact arrangement of the modular unit.
