摘要： A battery module for a motor vehicle includes two contact-making plates, which are arranged in parallel or approximately in parallel with one another, including a first and a second contact-making plate, and a plurality of battery cells, which are arranged next to one another and between the two contact-making plates. Each battery cell has a longitudinal axis and two axially opposite ends. The ends of each battery cell are connected to the contact-making plates, and the battery cells are arranged in such a way that i) an outer circumferential surface of each battery cell fully surrounded by adjacent battery cells touches outer circumferential surfaces of at least three adjacent battery cells, and ii) an outer circumferential surface of each battery cell not fully surrounded by adjacent battery cells touches outer circumferential surfaces of at least two adjacent battery cells.

摘要： An electrical machine arrangement for a motor vehicle includes a first electrical machine, a first energy store, which is connected to the first electrical machine for supplying power to the electrical machine, a second electrical machine, a second energy store, which is connected to the second electrical machine, for supplying power to the second electrical machine and which is connected to the first energy store by use of an intermediate circuit, and a coupling element. This coupling element is connected into the intermediate circuit and permits energy to be transmitted from the second energy store to the first energy store and can prevent energy transmission from the first energy store to the second energy store.

摘要： A charging device charges energy stores of an electrical machine arrangement for a motor vehicle. The charging device has a primary side with a first connection for connection to a power supply system and a secondary side with a second connection for connection to a second energy store. The charging device has, on the primary side, a third connection for connection to a first energy store and is provided with a control circuit for switching over the load flux such that, via the second connection, energy can be transmitted from the second energy store, via the third connection, to the first energy store.

摘要： The rechargeable battery arrangement includes a first plurality of series-connected first charge storage cells, a second plurality of series-connected second charge storage cells, and a third plurality of series-connected third charge storage cells. The arrangement further includes a first converter having a first connection pair is connected to the third plurality of series-connected third charge storage cells, and a second connection pair, connected in series with the first plurality of series-connected first charge storage cells. A series connection consisting of the first plurality of first charge storage cells and the first converter is connected in parallel to the second plurality of second charge storage cells. Moreover, the first converter is configured to convert at least one of a voltage and a current supplied by the third plurality of series-connected third charge storage cells, and to output said voltage and/or current at the second connection pair. In addition, a lowest potential of the second plurality of series-connected second charge storage cells forms a first connection of the accumulator arrangement, and a highest potential of the second plurality of series-connected second charge storage cells forms a second connection of the accumulator arrangement.
