[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example

[0023] like Figs. 1-2 As shown, a low-temperature starting lithium battery for parking air conditioning includes an upper shell 10 and a lower shell 20. The upper shell 10 and the lower shell 20 are joined together to form an installation cavity, and a lithium battery module is installed in the installation cavity.

[0024] Taking the 24200CV lithium battery as an example

[0025]

[0026]

[0027] As can be seen from the parameters in the table, compared with lead-acid batteries, the lithium battery in this application not only meets the requirements for low-temperature performance, but also has a high cycle life, meeting the requirements for parking functions.

[0028] The top of the upper housing 10 is provided with multiple connectors, which are electrically connected to the battery module in a counter-plugging manner. Existing lead-acid battery outer surface connectors and battery modules are mostly electrically connected by wire harnesses, which not only occupies internal installation space, but also poses certain safety hazards such as overheating and burnout. The lithium battery outer surface connectors and the connectors in the battery module of this utility model adopt a counter-plugging electrical connection, which has better safety and stability.

[0029] The lower edge of the upper housing 10 is provided with an upper outer edge 11, and the outer edge of the upper outer edge 11 is provided with a lower hanging 12, and a mating groove is formed between the bottom of the upper outer edge 11 and the inner side of the lower hanging 12; the upper edge of the lower housing 20 is provided with a lower outer edge 21, and the lower outer edge 21 is adapted to the mating groove.

[0030] Because this lithium battery uses a plug-in electrical connection, when closing the upper casing 10, the closing direction of the upper casing 10 must be consistent with the plugging direction of the connector to ensure the stability of the plug-in connection. This invention forms a mating groove by setting an upper outer edge 11 and a lower hanging part 12. Thus, when closing the upper casing 10, the closing action can only be performed when the mating groove aligns with the lower outer edge 21, thereby ensuring the accuracy and direction of the upper casing 10's closing and ensuring the stability of the plug-in electrical connection. It should be noted that the depth of the mating groove matches the thickness of the lower outer edge 21 and is greater than the plugging depth of the connector.

[0031] The connector includes an electrode terminal 40, a communication line 50, and a short interface 60. The end of the communication line 50 away from the upper housing 10 is equipped with a communication interface 51.

[0032] An explosion-proof valve 70 is installed on the top of the upper housing 10. By setting the explosion-proof valve 70, the safety of this lithium battery is further ensured.

[0033] Both the upper outer edge 11 and the lower outer edge 21 are provided with corresponding bolt holes. After the upper housing 10 and the lower housing 20 are closed together, they are fixed by passing through the bolt holes with anti-locking bolts 30.

[0034] In the prior art, the upper shell 10 and the lower shell 20 are both plastic shells, and the two are sealed with glue. To open them, destructive disassembly is required. After disassembly, the upper shell 10 and the lower shell 20 cannot be used. In this utility model, the upper shell 10 and the lower shell 20 are sheet metal parts, and the two are fixed together with anti-locking bolts 30, which facilitates disassembly. After disassembly, the upper shell 10 and the lower shell 20 can continue to be used.

[0035] A first corner bracket 13 is fixedly connected between the outer side wall of the upper housing 10 and the top of the upper outer edge 11, and the first corner bracket 13 and the bolt holes are misaligned.

[0036] A second bracket 22 is fixedly connected between the outer wall of the lower housing 20 and the bottom of the upper outer edge 11, and the second bracket 22 and the bolt holes are misaligned.

[0037] By setting the first corner bracket 13 and the second leg bracket 22, the structural stability of the connection between the upper shell 10 and the upper outer edge 11, and the lower shell 20 and the lower outer edge 21 is ensured.

[0038] A connecting bracket 80 is fixedly connected to the outer side wall of the lower housing 20, and the position of the connecting bracket 80 is adapted to the installation position of the truck.

[0039] Multiple handles 90 are installed on the outer side wall of the lower housing 20, and the multiple handles 90 are symmetrically designed.

[0040] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
