A battery power supply (1) for an industrial truck (8) used in a potentially explosive area is provided, having a housing (2) having a housing body (47) and a lid (4), wherein the housing body (47) has a receiving chamber (48) for receiving a battery tray (3) that has an inner chamber (20) having a traction battery (25) arranged therein, and the lid (4) is releasably placed on the housing body (47) using securing means (53), and the battery tray (3) has a battery tray lid (49) and a base (26) having walls (17, 18) extending away from the base (26), wherein, in a region adjacent to the base (26), at least one wall (17, 18) has a recess (19) penetrating the wall (17, 18) into the inner chamber (20).

The present invention relates to a battery module including a battery cell stack comprising a plurality of battery cells, a module housing configured to receive at least one battery cell stack disposed in an overall length direction, a high voltage (HV) connector configured to electrically connect battery modules to each other, a low voltage (LV) assembly configured to sense the voltage and temperature of the plurality of battery cells, an insulating oil configured to cool the plurality of battery cells, and a cooling port configured to allow the insulating oil to be introduced and discharged therethrough, wherein the insulating oil directly cools the plurality of battery cells while flowing in the module housing, whereby cooling efficiency and energy density are improved, and a battery pack including the same.

An air-zinc battery module includes a reception part having a sealed space formed therein, a gas storage part which is located in one area in the reception part and can discharge air or oxygen therefrom, and an air-zinc battery part which is located in another area in the reception part and includes at least one air-zinc battery cell for generating electricity when air or oxygen is supplied thereto.

An electrical system with replaceable batteries comprises an electrical system and a combined switch. The electrical system comprises a plurality of battery packs (1, 2, 3); all the battery packs are independently arranged each other; and an electric-quantity display device which is used for displaying the electric-quantity information indicating signals of the battery packs and a gear switch which is used for mutually switching the battery packs are arranged on the combined switch. Each battery pack comprises a battery (A.sub.1, A.sub.2, A.sub.3), a power switches (B.sub.1, B.sub.2, B.sub.3) and a battery management system (C.sub.1, C.sub.2, C.sub.3). The battery management systems receive and combine the output signals of the combined switches with the electric-quantity information indicating signals, thereby controlling whether the power switches are closed to provide power output or not.

A system can include a first battery module. The system can include a second battery module. The second battery module can have more lithium iron phosphate (LFP) battery cells than the first battery module.

A case system for lead batteries is provided. The case system has an essentially six sided cuboid shape with two pairs of parallel sidewalls perpendicular to each other. Each pair of sidewalls defines two opposite surfaces of the essentially cuboid shape and further defines an interior volume inside the case system. The case system includes a further pair of parallel sidewalls, each of them perpendicular to the sidewalls above and each with a surface area larger than that of any one of the surface areas of the above sidewalls. One of the sidewalls is arranged as a separate cover wall for sealing the case system. At least one division plane is further included in the case system. The division plane divides the interior volume, such as to form a plurality of compartments, each for storing an electrical cell. All division planes are perpendicular to the cover wall. Further, an electrical cell, a lead battery and a lead battery layout including the above are shown.

An air battery includes: a cell frame of an insulating material having a bottomed frame shape in which an electrolytic solution and an anode are stored; a cathode that is disposed opposite the anode across the electrolytic solution stored in the cell frame; and a current collecting member that is electrically connected to the anode, wherein the anode and the current collecting member are electrically connected to each other via a plurality of electrically conducting members that penetrate a bottom of the cell frame.
