The invention relates to a cooling plate (10) for battery cells (40), wherein the cooling plate (10) is in the form of a mounting plate and has mounting elements (12) for directly mounting the cooling plate (10) into a motor vehicle. It is further necessary for the cooling plate (10) together with a housing (20), in particular a half-shell housing, to form a closed-off space (30) for accommodating battery cells (40). The invention further relates to battery cells (40), to a battery cell module and also to a motor vehicle having a battery cell module of this kind.

A battery for a motor vehicle, in particular a high-voltage battery, including battery cells and a housing. The walls of the housing at the same time define a housing space, in which the battery cells are placed in a predetermined arrangement. Between the battery cells that are arranged in the housing space is provided an intermediate space. A passage element extends through the intermediate space from a first wall of the walls of the housing to a second wall on the opposite side of the walls of the housing.

A battery module is provided for a high-voltage accumulator of an electrically drivable motor vehicle, having one electric storage cell, two plate-shaped frame components which are arranged on the end faces and between which the electric storage cell is arranged, one plate-shaped heat sink with at least one cooling channel system which is connected to the electric storage cells in a thermally conductive manner, one fluid inlet which is communicatively connected to the cooling channel system via one first fluid connection, and one fluid outlet which is communicatively connected to the cooling channel system via at least one second fluid connection. The fluid inlet and the fluid outlet are arranged adjacently to a respective plate-shaped frame component remotely from the heat sink. To reduce the assembly complexity associated with the assembly, the battery module has at least one clamping device. The fluid connection having the first connection unit has at least one second connection unit which is communicatively connected to the cooling channel system, and the two connection units can be clamped against each other by the clamping device. The second connection unit is arranged adjacently to the respective plate-shaped frame component remotely from the heat sink and is connected to the plate-shaped heat sink at the end face, and the fluid line is connected to at least one of the two connection units via at least one seal.

A battery housing part for a traction battery of an electric or hybrid vehicle. A first partial region of the battery housing part is composed of a plastic and at least one second partial region is composed of a material that is different therefrom. In this way, high degree of stiffness of the battery housing part can be achieved together with low weight. The second partial region that is composed of a material of a different type can be provided in a targeted manner where the at least one second partial region enables the greatest advantage in respect of the stiffness of the battery housing part. The use of a plastic for other partial regions of the battery housing part makes it possible to keep the weight of the battery housing part low.

A battery lid lock structure comprises: a battery lid (10), a slide switch (20), a lock (30), and a main body (40). A longitudinally extended slide slot (11) is provided on the battery lid (10); the slide switch (20) is mounted on the slide slot (11) and is slidable back and forth between a first position and a second position, and comprises a lock head (21) located in the inner side of the battery lid (10); the lock head (21) and the lock (30) are connected together to drive the lock (30) to slide synchronously; the lock (30) comprises a bolt (31) extended and disposed in the same direction as the slide slot (11); a slot (41) correspondingly matching the bolt (31) is provided on the main body (40); when the slide switch (20) is at the first position, the bolt (31) and the slot (41) are engaged, when the slide switch (20) is at the second position, the bolt (31) and the slot (41) are separated. By disposing the slidable slide switch (20) on the battery lid (10) to drive the engagement or the separation of the lock (30) and the slot (41) on the main body (40), the present invention has fewer components and a structure being convenient to mount the slide switch (20) and the lock (30) and enables enough sufficient mating surface between the bolt (31) and the slot (41), thus guaranteeing the stability of the mating and reducing cost.

There is provided a battery pack capable of supplying a stable output and of being charged stably in a low temperature environment (for instance, 0° C. or lower). A battery pack (1) includes: a battery group (11) having a first battery (10A) and a second battery (10B) disposed around the first battery (10A); and a heater (14) that is disposed on an outer peripheral side of the battery group (11), famed by the second battery (10B), and that generates heat by being energized by the first battery (10A). The first battery (10A) is allowed to be charged and discharged with a higher current than a current of the second battery (10B) in a temperature range lower than or equal to a predetermined temperature.
