The present disclosure provides a battery pack including a housing, wherein the housing has a bottom portion, on which are disposed a first length side wall and a second length side wall that extend upward along a length direction of the bottom portion and are oppositely disposed, and a first width side wall and a second width side wall that extend upward along a width direction of the bottom portion and are oppositely disposed; the housing comprises a first step and a second step disposed at two ends of the first length side wall; the housing further comprises a first metal wiring terminal and a second metal wiring terminal, wherein the first metal wiring terminal and the second metal wiring terminal are disposed on the first step and the second step, respectively; a material for bearing the first metal wiring terminal and the second metal wiring terminal is a first plastic material, while other parts of the housing are made of a second plastic material, or most of other parts of the housing are made of the second plastic material. The two materials have different characteristics suitable for a requirement of the battery pack on the material.

Battery pack with housing made of two materials

The present disclosure provides a battery pack including a housing, wherein the housing has a bottom portion and side walls extending upward around a periphery of the bottom portion; an upper portion opening is formed at top ends of the side walls extending upward; an upper cover is mounted on the upper portion opening of the housing; and the battery pack comprises: multiple flat battery cells; and a first end plate and a second end plate, wherein when the multiple battery cells are sequentially arranged and mounted into the housing from the upper portion opening, the first end plate and the second end plate are located at two end sides of the sequentially arranged multiple battery cells to laterally fix the sequentially arranged multiple battery cells. The two end plates may absorb deformation of the battery cell while expanding.

Battery pack with two end plates

The present disclosure provides a battery pack for a hybrid vehicle. The battery pack includes: multiple battery cells, a housing, a first end plate, a second end plate, a bearing plate and an upper cover, wherein the housing is provided with a bottom portion and side walls extending from the periphery of the bottom portion and forming an upper portion opening; the housing is configured for accommodating the multiple battery cells and the two end plates, when the multiple battery cells are sequentially arranged and mounted into the housing, the first end plate and the second end plate are located at two end sides of the sequentially arranged multiple battery cells to laterally fix the multiple battery cells; the bearing plate is mounted above the top portions of the multiple battery cells; and the upper cover is mounted above the housing to cover the upper portion opening of the housing.

Battery pack

The present disclosure provides a battery pack including: multiple flat battery cells, a housing, a bearing plate and an upper cover, wherein a middle recessed portion is formed between the protruding battery cell anode and battery cell cathode disposed on the top portion of each of the multiple battery cells; a surface of the middle recessed portion is provided with at least one seal-breakable opening arranged to discharge the gas generated in the battery cell when broken; the multiple middle recessed portions at the top portions of the multiple battery cells form a battery top portion through-slot; a bottom portion of the bearing plate is provided with a bearing plate bottom portion through-slot; the bearing plate bottom portion through-slot is press-fitted with the battery top portion through-slot to form a lateral gas discharging passage wherein one end of the lateral gas discharging passage is provided with an outlet, and another end of the lateral gas discharging passage is blocked. The gas discharging passage of the present disclosure utilizes the existing structures of the battery pack without additionally designing a separate specific gas discharging passage.

Battery pack with gas discharging passage

The present invention provides a battery control system for controlling a battery pack that is formed by a plurality of battery cells. The battery control system comprises: a detecting circuit for detecting at least one operation parameter of the battery pack; an activating circuit, which receives the at least one operation parameter from the detecting circuit, for generating a first control signal when the detected at least one operation parameter exceeds or is below at least one critical-level threshold; a supervision unit, which receives the at least one operation parameter from the detecting circuit, for managing the battery pack and generating a second control signal when the at least one operational parameter exceeds or below at least one cap-level threshold; a switching circuit, which receives the first control signal from the activating circuit and/or the second control signal from the supervision unit, for connecting the battery pack to and disconnecting the battery pack from an power output in response to the first control signal and/or the second control signal.

Scalable modular design of a 48-volt li-ion battery management system

The present invention provides a battery that includes a plurality of serially connected battery cells. The battery includes an upper housing and a lower housing. The battery comprises: a wire harness assembly; a middle housing that includes a plurality of cell chambers for accommodating the top sections of the plurality of serially connected battery cells. The lower housing includes a plurality of cell chambers for accommodating the bottom sections of the plurality of serially connected battery cells; and the middle housing has a top surface for installing the wire harness assembly () and the plurality of cell chambers beneath the top surface () of the middle housing.

Modular design of a 48-volt li-ion battery for ease of assembly and disassembly

A battery module includes a rigid external casing made, for example, of a metallic sheet material. Securement features, tabs, and so forth may be formed in the material of the casing. The casing may be made by stamping and bending metallic sheet. A liner is disposed in the casing, and one or more battery cells are disposed in the liner. The liner may comprise an insulative sheet material that is cut and folded to generally conform to the casing. The structure may include a bus bar assembly, compression members, a thermal component and other structural and functional elements.
