Description

Technical Field

[0003] It is understood that there are mainly the following types of battery fixing systems for new energy commercial vehicles, and their shortcomings and deficiencies are as follows:

[0004] 1. Battery side-mounted fixing system: mainly based on welded frames, the battery pack is pushed sideways or hoisted into the frame, and then the battery is pushed into the opening and fixed. This frame is mainly used to carry standard battery packs. This battery fixing system improves vehicle handling and safety due to its low center of gravity. However, due to the complex structure of the welded frame and the large number of welds, its production is cumbersome, and the product has large deformation and dimensional deviation. In addition, the complex frame structure occupies the space of the vehicle, affecting the power layout and the wheelbase of the vehicle.

[0005] 2. Back-mounted battery fixing system: This battery fixing system has good overall force because its center of gravity is at the center of the frame. The frame is mostly welded. The standard battery pack is pushed into the frame from the side, and then the frame is hoisted onto the frame and connected to the fixing structure. This fixing method raises the center of mass of the vehicle, and the battery pack is located directly behind the cab, which affects the vehicle's handling and reduces the safety of the vehicle.
