Abstract: The invention relates to a housing (5; 10, 20, 30) for a plurality of battery cells (40). The housing (5; 10, 20, 30) comprises three main components (10, 20, 30). A first main component is formed by a container (10) for receiving a plurality of battery cells (40), a second main component is formed by a support (20) for electric and/or electronic components (22), and a third main component is formed by a cover (30). According to the invention, the electric and/or electronic components (22) are additionally arranged at least partly on a circuit board (24). The invention further relates to a battery cell module (50), to a motor vehicle with a battery cell module (50), and to a method for producing a battery cell module.

Abstract: A battery system, having at least one battery cell, wherein a circuit arrangement is provided in a negative current path. The circuit arrangement includes two series-connected field-effect transistors, of which the battery-cell-side field-effect transistor has a charge-current-blocking diode path and can be bridged by a precharging path with a precharging resistor, and the field-effect transistor which is remote from the battery cell has a discharge-current-blocking diode path. The system also includes a voltmeter for detecting a voltage present across the field-effect transistor directly upstream and downstream of the field-effect transistor which is remote from the battery cell; and a current sensor for detecting a current flowing through the negative current path.
