Abstract
A battery cell having first cell connectors, a galvanic cell and a first switching unit electrically coupled to the first cell connectors and the galvanic cell for electrically coupling the galvanic cell to the first cell connectors depending on a switching state of the first switching unit. The battery cell has second cell connectors electrically separated from the first cell connectors and a second switching unit electrically coupled to the second cell connectors and the galvanic cell for electrically coupling the galvanic cell to the second cell connectors depending on a switching state of the second switching unit.
Claims15
A battery cell comprising:
- four first cell connectors configured as main terminals;
- a galvanic cell;
- and
- a first switching unit electrically coupled to the first cell connectors, wherein the galvanic cell is configured to be electrically coupled to the first cell connectors depending on a switching state of the first switching unit;
- two second cell connectors configured as secondary terminals that are electrically isolated from the four first cell connectors, wherein the second cell connectors are connected to two center taps of the first switching unit;
- and
- a second switching unit that is configured to be electrically coupled to the second cell connectors to electrically couple the galvanic cell to the second cell connectors depending on a switching state of the second switching unit.
