A battery case for a vehicle driven by an electric motor, said battery case comprising a tray part (1, 1.1, 1.2, 1.3) which has a base (2, 2.1, 2.2, 2.3) onto which side walls (3, 3.1, 3.2, 3.3) having a mounting flange (4) are molded, and comprising a frame structure (5, 5.1, 5.2) which surrounds the tray part (1, 1.1, 1.2, 1.3) on the outer side thereof and has a hollow chamber (11, 11.1, 11.2). The side walls (3, 3.1, 3.2, 3.3) of the tray part (1, 1.1, 1.2, 1.3) are at the same time part of the frame structure (5, 5.1, 5.2) and separate the tray interior from the hollow chamber (11, 11.1, 11.2) of the frame structure (5, 5.1, 5.2). The side walls (3, 3.1, 3.2, 3.3) with their mounting flange (4) are part of the frame structure (5, 5.1, 5.2) and the frame structure (5, 5.1, 5.2) has at least two additional frame members (6, 8, 3.1, 4.1, 13, 3.2, 4.2, 13.1) connected to the tray part (1, 1.1, 1.2, 1.3) for completing the frame structure (5, 5.1, 5.2), of which a first frame member (6, 3.1, 3.2) has a leg (3, 3.1, 3.2, 6.1) which is opposite the side wall (3, 3.1, 3.2, 3.3) of the tray part (1, 1.1, 1.2, 1.3) and an upper terminating leg (4.1, 4.2, 7) for connection to the tray part (1, 1.1, 1.2), and of which a second frame member is a closing plate (8, 13, 13.1) that connects the first frame member (6, 3.1, 3.2) to the tray part (1, 1.1, 1.2) on the undersides thereof.
