Battery arrangement for a motor vehicle
A battery arrangement for a motor vehicle includes a first electrical energy store, a second electrical energy store, a charging connection, and a supply connection. The arrangement further includes first through seventh switches. The battery arrangement is switchable into four operating states via respective opening and closing of the first through seventh switches.
1. A battery arrangement for a motor vehicle, comprising:
a first electrical energy store;
a second electrical energy store;
a charging connection with a positive pole and a negative pole;
a supply connection with a positive pole and a negative pole;
a first switch that connects a positive pole of the first electrical energy store to the positive pole of the supply connection;
a second switch that connects a negative pole of the first electrical energy store to the negative pole of the supply connection;
a third switch that connects a positive pole of the second electrical energy store to the positive pole of the supply connection;
a fourth switch that connects a negative pole of the second electrical energy store to the negative pole of the supply connection;
a fifth switch that connects the positive pole of the first electrical energy store to the negative pole of the second electrical energy store;
a sixth switch that connects the negative pole of the first electrical energy store to the negative pole of the charging connection; and
a seventh switch that connects the positive pole of the second electrical energy store to the positive pole of the charging connection.
2. The battery arrangement according to claim 1 , wherein the battery arrangement is switchable into a first operating state when the fifth switch, the sixth switch, and the seventh switch are closed.
3. The battery arrangement according to claim 2 , wherein the battery arrangement is switchable into a second operating state when the first switch, the second switch, the third switch, and the fourth switch are closed.
4. The battery arrangement according to claim 3 , wherein the battery arrangement is switchable into a third operating state when the first switch, the second switch, the third switch, the fourth switch, the sixth switch, and the seventh switch are closed.
5. The battery arrangement according to claim 4 , wherein the battery arrangement is switchable into a fourth operating state when the first switch, the second switch, the third switch, the fourth switch, the sixth switch, the seventh switch, and/or the fifth switch are opened.
