    摘要: A battery cell for a battery of a motor vehicle having a battery cell housing, in which a galvanic element is accommodated. The battery cell can be electrically connected to at least one other battery cell of the battery by way of two electrical connections. The battery cell has at least one switching element, which is designed for making and breaking a conductive electrical connection between an arrester of the galvanic element and at least one of the electrical connections. A driver module is disposed inside the battery cell housing to control the switching element so that the conductive electrical connection between the arrester and the electrical connections are controlled.
