[0020] like Figure 1-4The diagram shows a power battery arrangement structure for a hybrid commercial vehicle, including a battery frame 1, a power battery 2, a battery cooling unit 3, a battery controller 4, a motor controller 5, a multi-function controller 6, and a motor cooling unit 8. The power battery 2, battery cooling unit 3, battery controller 4, motor controller 5, multi-function controller 6, and motor cooling unit 8 are all mounted on the battery frame 1. The battery cooling unit 3 and motor cooling unit 8 are commonly used motor cooling systems and battery cooling systems in hybrid commercial vehicles.

[0021] The battery controller 4, motor controller 5, and multi-function controller 6 are positioned on the battery frame 1 at a higher position than the power battery 2 on the battery frame 1.

[0022] It also includes a dual-chamber expansion tank 7; the dual-chamber expansion tank 7 is mounted on the battery frame 1. The dual-chamber expansion tank 7 replenishes coolant to both the battery cooling unit and the battery cooling system.

[0023] It also includes a charging socket 9; the charging socket 9 is disposed on the battery frame 1.

[0024] It also includes lifting lugs 11; the top of the battery frame 1 is provided with lifting lugs 11. The lifting lugs 11 can realize the hoisting of the entire frame.

[0025] It also includes a cover plate 12; the battery frame 1 is provided with cover plates 12 on all four sides and the top wall. The cover plate 12 can cover the inside of the frame and improve the aesthetics. The cover plate 12 can be provided with heat dissipation holes as needed.

[0026] The battery frame 1 includes a chassis frame connecting plate 10, a support frame 13, and vertical beams 14. The support frame includes crossbeams and longitudinal beams. Several longitudinal beams are arranged between two crossbeams. Several support frames 13 are arranged sequentially from bottom to top, and the support frames 13 are supported by several vertical beams 14 at the front and rear. The chassis frame connecting plate 10 and the charging socket connecting plate 91 are respectively arranged at the bottom of the lowest support frame 13. The chassis frame connecting plate 10 is used to connect the frame to the chassis frame. Furthermore, the top of the four vertical beams 14 around the battery frame 1 is provided with lifting lugs 11, and a top frame is provided at the top, which is also composed of several top longitudinal beams arranged between two top crossbeams. Cover plates 12 are provided on the four side walls and the top wall of the frame.

[0027] The battery frame 1 has a three-layer support frame. The first and second layers each house the power battery 2, while the third layer houses the battery cooling unit 3, battery controller 4, motor controller 5, and multi-function controller 6. The rightmost second and third layers house the motor cooling unit 8, with a dual-chamber expansion tank 7 above it. A charging socket 9 is mounted on the charging socket connection plate 91. The overall size of the third-layer support frame is smaller than that of the second-layer support frame, just enough to accommodate the motor cooling unit 8. The battery controller 4, motor controller 5, and multi-function controller 6 can be mounted on the battery frame using appropriate brackets. By centrally mounting the power battery 2, battery cooling unit 3, battery controller 4, motor controller 5, multi-function controller 6, motor cooling unit 8, dual-chamber expansion tank 7, and charging socket 9 on the frame, the chassis layout is kept as consistent as possible with conventional diesel chassis layouts, improving modularity and layout versatility. Placing each controller on the top layer of the frame also provides advantages in maintenance convenience. The power battery 2 is located at the bottom of the frame, which helps lower the overall system center of gravity.
