Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] See Figure 1 The figure shows a structural diagram of a power domain control frame-type battery pack according to an embodiment of the present invention. The battery pack includes an integrated domain control module 1 and a frame-type battery module 2.

The integrated domain control module 1 includes an electronic control module 11, a thermal management module 12, an integrated domain control box 13, and an integrated domain control cover plate 14.

[0057] The electronic control module 11 and the thermal management module 12 are housed inside the receiving cavity of the integrated domain control enclosure 13, with the integrated domain control cover 14 covering the top of the integrated domain control enclosure 13. The thermal management module 12 may have an independent housing, connected to the electronic control module 11 and the frame-type battery module 2 via a quick-release interface for heat dissipation channel connection and electrical connection, facilitating inspection and maintenance of the thermal management module 12. The thermal management module 12 and the electronic control module 11 can be separated by a connector panel, with the electronic control module 11 located near the front panel of the integrated domain control enclosure 13, and the thermal management module 12 located near the rear panel of the integrated domain control enclosure 13.

[0058] In some embodiments, the contact surfaces of the integrated domain controller enclosure 13 and the integrated domain controller cover 14 are provided with sealing rubber gaskets. The sealing rubber gaskets can be fixed to the integrated domain controller enclosure 13 and / or the integrated domain controller cover 14 by bolts to ensure the sealing of the electronic control module 11.

[0059] The frame-type battery module 2 is used to provide power to the electronic control module 11, the thermal management module 12 and other external modules.

[0060] The frame-type battery module 2 includes multiple stacked single-layer boxes and cell assemblies placed inside the receiving cavity of the single-layer boxes; the single-layer box includes a lower battery pack box 21 and a battery pack upper cover plate 22 covering the top of the lower battery pack box 21.

[0061] For example, the lower housing 21 and the upper cover 22 of the battery pack are bolted together to form a single-layer housing. The frame-type battery module 2 includes multiple single-layer housings fixed by bolts, and high and low voltage connection connectors are provided between the housings to facilitate high and low voltage connections between the housings. Optionally, limit posts are also provided between the single-layer housings to ensure accurate alignment of multiple housings during high and low voltage connections and to limit relative movement between the housings, preventing loosening or damage to the connectors due to accidental collisions or vibrations, and ensuring the safety and reliability of the electrical connections.

[0062] Adjacent single-layer enclosures are fixed by positioning pins on the top of the battery pack cover plate 22 in the lower enclosure and positioning holes on the bottom of the battery pack lower enclosure 21 in the upper enclosure; adjacent cell assemblies are electrically connected by quick-connect electrical interfaces.

[0063] The integrated domain controller enclosure 13 is fixed to the top of the battery pack cover plate 22 of the uppermost single-layer enclosure of the frame-type battery module 2 by bolts, so that the integrated domain controller module 1 and the frame-type battery module 2 become a structurally stable whole.

[0064] Therefore, this utility model embodiment provides a power domain control frame-type battery pack including an electronic control module, a thermal management module, and a frame-type battery module. The electronic control module and the thermal management module are both housed in an integrated domain control box, reducing the additional housings and wiring harnesses required for each module as an independent component. This reduces volume and weight, increases integration, and lowers manufacturing costs. The integrated domain control box and multiple single-layer boxes in the frame-type battery module can be detachably stacked, improving the integration of components in the electric vehicle powertrain and enabling quick disassembly and electrical connection. This facilitates rapid maintenance and replacement, improving the maintainability of the battery pack.

[0065] In addition, the frame-type battery module includes multiple single-layer housings. The battery pack cover plate in each single-layer housing is equipped with connectors for connecting the single-layer housings and the integrated domain control module with the frame-type battery module. The frame-type battery module simplifies the fixing structure of the battery housing, using the housing itself as a protection, sealing, support and fixing structure for the cell components, providing anti-collision protection, eliminating the need for traditional battery pack mounting frames, reducing manufacturing and installation costs, reducing the weight of the power domain control frame-type battery pack, and enhancing the space utilization and lightweighting of the electric vehicle battery system.

[0071] The support base 112 is located at the bottom of the receiving cavity of the integrated domain control enclosure 13 and is welded to the connector panel 111 to support multiple electronic control units 113.

[0080] The integrated control unit 1133 is used to comprehensively manage the cells of the frame-type battery module 2, including data acquisition, status assessment, equalization control, safety protection, and transmission of electrical energy and communication signals. By monitoring the operation of the accelerator and brake pedals, it calculates and adjusts the required drive torque and braking torque in real time to ensure that the drive motor, braking system and steering system operate according to preset performance parameters and make feedback adjustments.

Optionally, a sealing ring may also be provided at the IGBT module.

[0088] See Figure 7This figure is a heat dissipation channel structure diagram provided by an embodiment of the present invention. The electronic control module 11 and the frame-type battery module 2 in the integrated domain control module 1 both have heat dissipation channels.

[0089] Among them, the heat dissipation channel of the frame-type battery module 2 is set in the bottom plate of the battery pack lower box 21, and a three-way non-reverse liquid cooling quick-connect water nozzle is set at the rear panel of the battery pack lower box 21 of each single-layer box, and the water nozzles are connected by water pipes.

[0090] The electronic control module 11 includes a heat dissipation channel 114, which is fixed to the support base 112 by a dedicated connector and contacts different electronic control units 113. The water nozzle of the heat dissipation channel 114 is integrated on the support base 112 and is used to introduce cooling medium to achieve heat exchange.

[0091] Specifically, the heat dissipation channel 114 includes an inlet channel 1141 for the electronic control module 11, an outlet channel 1145 for the electronic control module 11, a first heat dissipation channel 1142, a connecting water channel 1143, a second heat dissipation channel 1144, a thermal management inlet channel 1146, a frame-type battery module inlet channel 1147, and a frame-type battery module outlet channel 1148.

[0093] For example, the heat dissipation channel 114 has an S-shaped channel (connecting water channel 1143) and a straight channel (second heat dissipation channel 1144) connected to the liquid outlet channel 1145.
