Description

Technical Field

[0001] This utility model belongs to the field of battery technology, specifically relating to a split-type power battery pack. Background Technology

[0002] Some special-purpose vehicles have high voltage and high capacity requirements for battery packs, but due to space limitations, the battery packs cannot be manufactured as a whole. Moreover, when the battery pack needs to be repaired or replaced, the entire pack needs to be inspected and replaced, leaving the electrical equipment in a completely standby state, which is inflexible. Therefore, how to adapt the power supply to such a state is a technical problem that needs to be considered and solved. Utility Model Content

[0003] In view of the problems raised in the background art above, the purpose of this utility model is to provide a split-type power battery pack.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A split-type power battery pack includes a main box and an auxiliary box. Both the main box and the auxiliary box are equipped with battery compartments and compartment covers. Both the main box and the auxiliary box are provided with battery communication interfaces and series interfaces. The main box is provided with a battery positive output interface, and the auxiliary box is provided with a battery negative output interface.

[0006] The auxiliary box contains an auxiliary box electrical assembly, and the main box contains a main box electrical assembly. Both the auxiliary box electrical assembly and the main box electrical assembly are connected to their respective battery compartment circuits.

[0007] Furthermore, both the main box and the auxiliary box are equipped with handles, a design that facilitates the extraction and movement of the main box and the auxiliary box.

[0008] Furthermore, both the main box and the auxiliary box are equipped with explosion-proof valves. In this design, the explosion-proof valve is a core component to ensure the safety of the power battery. It can realize functions such as directional pressure relief, pressure regulation, thermal runaway response and multiple protection integration, and is a key barrier for battery thermal management and safety protection.

[0009] Furthermore, the battery compartment is equipped with reinforcing ribs on its outer side, and a battery pack is installed inside the battery compartment. The battery pack is equipped with bridging copper busbars, module transverse pressure strips, and module longitudinal pressure strips. This design allows the reinforcing ribs to improve the structural strength of the battery compartment and provide good resistance to pressure and impact, while the bridging copper busbars, module transverse pressure strips, and module longitudinal pressure strips effectively ensure the power connection and installation strength of the battery pack.

[0010] Furthermore, the main box and the auxiliary box have the same external box structure, but are marked with labels. This design facilitates manufacturing.

[0011] The beneficial effects of using this utility model are as follows:

[0012] The structural design of this utility model, with its split design, allows the other unit to switch to supply low-power electricity when one of the main unit or the auxiliary unit malfunctions, thus achieving some basic power supply.

[0013] The structural design of this utility model is suitable for use in situations where space constraints prevent the battery pack from being manufactured as a single unit. Attached Figure Description

Detailed Implementation

[0019] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1 , Figure 2 As shown, the present invention provides a split-type power battery pack, including a main box 1 and an auxiliary box 2. Both the main box 1 and the auxiliary box 2 are equipped with battery compartments 3 and compartment covers 4. Both the main box 1 and the auxiliary box 2 are provided with battery communication interfaces 5 and series interfaces 6. The main box 1 is provided with a battery positive output interface 7, and the auxiliary box 2 is provided with a battery negative output interface 8.

[0021] The auxiliary box 2 is equipped with an auxiliary box electrical assembly 9, and the main box 1 is equipped with a main box electrical assembly 10. Both the auxiliary box electrical assembly 9 and the main box electrical assembly 10 are connected to their respective battery compartments 3 via circuitry.

[0022] It is preferable that both the main box 1 and the auxiliary box 2 are equipped with handles 11. This design facilitates the lifting and moving of the main box 1 and the auxiliary box 2. In fact, the number, specifications, style and installation position of the handles 11 can also be considered according to the specific situation.

[0023] Ideally, both the main box 1 and the auxiliary box 2 are equipped with explosion-proof valves 12. In this design, the explosion-proof valve 12 is a core component to ensure the safety of the power battery. It can realize functions such as directional pressure relief, pressure regulation, thermal runaway response and multiple protection integration. It is a key barrier for battery thermal management and safety protection. In fact, the installation position and installation measures of the explosion-proof valve 12 can also be considered according to the specific situation.

[0024] The battery compartment 3 preferably has a reinforcing rib 13 installed on its outer side, and a battery pack 14 installed inside the battery compartment 3. The battery pack 14 is equipped with a bridging copper busbar 15, a module transverse pressure strip 16, and a module longitudinal pressure strip 17. With this design, the reinforcing rib 13 can improve the structural strength of the battery compartment 3 and has good pressure and impact resistance. The bridging copper busbar 15, the module transverse pressure strip 16, and the module longitudinal pressure strip 17 effectively ensure the power connection and installation strength of the battery pack 13. In fact, the number of battery packs 14 inside the battery compartment 3 and the installation and fixing structure can also be considered according to the specific situation.

[0025] It is preferable that the main box 1 and the auxiliary box 2 have the same external structure, but are marked. This design is conducive to manufacturing. In fact, the external structure of the main box 1 and the auxiliary box 2 can also be considered according to the specific situation.

[0026] In this implementation case, when using a split-type power battery pack, the main battery pack 1 and the auxiliary battery pack 2 can be placed and installed separately according to requirements. This is suitable for situations where the space for a single storage location is too small but the power supply needs to be guaranteed. After the positions of the main battery pack 1 and the auxiliary battery pack 2 are determined, the circuits of the two are connected by wires through the series interface 6. During use, the power is output through the battery positive output interface 7 and the battery negative output interface 8. Under the circuit switching of the auxiliary battery electrical group 9 and the main battery electrical group 10, the normal power output is guaranteed. The battery communication interface 5 provides real-time feedback on the usage status of the battery pack 14 in the battery compartment 3.

[0027] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
