Embodiment Construction

[0030] Please refer to figure 1 and figure 2 , a new energy vehicle battery PACK lightweight cover, including a cover body 1 made of resin and fiber fabric, the cover body is laid with foam reinforcement ribs 2, a total of 2 layers of fiber fabric, and the fiber fabric is glass fiber One or more of fabrics, carbon fiber fabrics, and basalt fabrics. The reinforcing ribs are laid in a cross shape, the reinforcing ribs are foam reinforcing ribs or rigid reinforcing ribs, and a small piece of fiber fabric for edge sealing is laid beside the reinforcing ribs. The resin is a flame-retardant thermosetting resin, and the flame-retardant thermosetting resin is an unsaturated resin, epoxy resin, phenolic resin or vinyl resin. The lightweight upper cover of the new energy vehicle battery PACK also includes a fireproof paint layer sprayed on the outer surface. The wall thickness of the lightweight upper cover of the new energy vehicle battery PACK is 1mm-2mm.

Abstract

The invention discloses a lightweight upper cover of a new energy automobile battery PACK and a manufacturing method thereof, the upper cover comprising an upper cover body made of resin and fiber fabric, and the upper cover body being provided with a reinforcing rib laid in a cross shape. The wall thickness of the upper cover is 1mm to 2mm. By adopting a fiber fabric and foam reinforcing rib structure, flame retardant thermosetting resin and fire-retardant paint layer, the PACK lightweight upper cover of the new energy vehicle battery with high strength, light weight and good fire-retardant performance is manufactured. The invention has the advantages of high strength, light weight, good fireproofing performance and low cost. Compared with an aluminum alloy upper cover, the weight is reduced by 10%-30%, the energy density of the battery is improved, at the same time, the battery has good fireproof performance and mechanical performance, the lightweight upper cover of the new energy vehicle battery PACK in the invention is selected, the molding process is simple, and the cost is further reduced.

Description

technical field [0001] The invention relates to the technical field of automobile body parts. Background technique [0002] A battery pack (battery PACK) refers to a unit that includes a battery pack, a battery pack management module, a battery box, and corresponding accessories, and can obtain electrical energy from the outside and output electrical energy externally. At present, the lightweight top covers of battery packs that are common on the market are mainly made of the following materials: first, aluminum alloy materials; second, SMC fiber-reinforced composite materials; third, thermoplastic fiber-reinforced composite materials; fourth, carbon fiber composite materials. The above four battery PACK covers have certain defects: the insulation and acid and alkali corrosion resistance of aluminum alloy materials are poor; the mechanical properties of SMC fiber reinforced composite materials are average, and the lightweight effect is not obvious; thermoplastic fiber reinfo...
