After the domain controller 20 is fully plugged into the opening 11, the domain controller 20 covers the opening 11, thereby forming a whole with the housing 10.

[0034] The domain controller 20 is inserted into the opening 11 along the first direction X, which means that at least a portion of the domain controller 20 extends into the opening 11, so that the domain controller 20 can be electrically connected to the battery module 30 in the accommodating cavity. At the same time, the domain controller 20 closes and covers the opening 11, so as to encapsulate the battery module 30 inside the box 10.

[0035] Optionally, one or more battery modules may be provided in the accommodating cavity. When there are multiple battery modules, the multiple battery modules may be connected in series, in parallel, or in a series-parallel hybrid manner, and the main interface of the multiple battery modules after being connected is electrically connected to the domain controller 20, thereby achieving conduction between the domain controller 20 and the battery modules, and controlling the battery modules accordingly.

[0036] Optionally, the domain controller 20 may include at least one of a battery management system, a vehicle control unit, a motor control unit, a circuit breaker power supply, a power distribution unit, a power conversion module, and an on-board charging unit.

[0037] The domain control battery 100 provided in the embodiment of the present application includes a box body 10, a domain controller 20 and a battery module 30. The battery module 30 is arranged in the box body 10, and an opening 11 connected to the accommodating cavity in the box body 10 is opened on the box wall of the box body 10, and a first limiting portion 12 is provided on the peripheral wall of the opening 11. The domain controller 20 is plugged into the opening of the box body 10 along the first direction X and is electrically connected to the battery module 30 in the box body 10. The domain controller 20 has a second limiting portion 21, and the first limiting portion 12 and the second limiting portion 21 cooperate with each other, and limit the relative movement of the domain controller 20 and the box body 10 along the second direction Y, so as to achieve the purpose of limiting the domain controller 20 in the second direction Y, effectively avoiding the shaking of the domain controller 20 under vibration and impact conditions, and improving the installation reliability and stability of the domain controller 20.

[0038] In some embodiments, one of the first limiting portion 12 and the second limiting portion 21 includes a slot 211 extending along the first direction X, and the other of the first limiting portion 12 and the second limiting portion 21 is engaged with the slot 211 .

[0039] Since the card slot 211 extends along the first direction X, when the domain controller 20 is plugged into the opening 11 along the first direction X, the other of the first limiting portion 12 and the second limiting portion 21 can be gradually inserted into the card slot 211, thereby achieving the cooperation between the first limiting portion 12 and the second limiting portion 21 in a very simple way.

[0040] The other of the first limiting portion 12 and the second limiting portion 21 for cooperating with the slot 211 can be in the form of a bump, a rib, a claw or the like.

The second limiting portion 21 may be formed on the outer surface of the side support plate 23. The limiting rib 212 protrudes outward from the outer surface of the side support plate 23, thereby forming a card slot 211 on the outer surface of the side support plate 23.

[0044] When the domain controller 20 is plugged into the opening 11 , the starting end of the limiting rib 212 first approaches the opening 11 . A guide portion is provided at the starting end of the limiting rib 212 , and the guide portion extends obliquely to guide the limiting rib 212 to extend into the opening 11 more smoothly.

[0045] In the embodiment of the present application, two limiting ribs 212 are provided to form the card slot 211. Not only is the forming method simple, but the limiting ribs 212 can also act as reinforcing ribs, thereby improving the structural strength of the domain controller 20 and avoiding damage or breakage.

[0049] The two fixing sections 122 and the snap-in section 121 are arranged along the first direction X, so that the first limiting portion 12 can form a strip structure extending along the first direction X, matching the structural form of the second limiting portion 21, so that the first limiting portion 12 can be snapped into the snap-in groove 211 of the second limiting portion 21.

[0050] Optionally, the clamping section 121 and the fixing section 122 may be integrally formed.
