Overall, base cover thickness was reduced from 14 to 4.5 millimeters top cover thickness was reduced to just more than 2 millimeters. “ added a lot more rigidity to the part, and meant we could reduce the skin thickness even more,” Dugmore says. In transitioning the design to composites, TRB was able to reduce the overall skin thickness of the panel while also adding shape in the form of molded-in internal ribs. In the process, the team learned how to build a battery cover to very tight tolerances, meet high impact requirements and mechanical properties, and provide the weight savings desired.ĭugmore explains that the original design for the bottom cover was for a flat panel comprising a metallic honeycomb structure. It was a short-run project, Dugmore says, with only 24 sets of top and bottom battery covers produced by hand. While supplying parts for the NIO (Shanghai, China) EP9 electric sportscar, which was designed for the Formula E racing circuit, TRB was approached about development of a composite battery enclosure for the vehicle - a new application at the time for the company. manufacturing facility in Richmond, Ky., in early 2021.Īccording to Andrew Dugmore, president of TRB Group, the company has supplied composite honeycomb panels for racing and low-volume sports cars for decades. Recently, the company has transitioned its materials knowledge and automation experience into the electric vehicle market, with a battery enclosure scheduled to begin serial production at the company’s new U.S. bus manufacturer, the need for a lightweight battery enclosure that could be designed to fit within a tight space envelope led to new opportunities for TRB Lightweight Structures (Huntingdon, U.K.), a company well known for design and manufacture of composite components for the rail, automotive, aerospace and industrial markets. The goal was to build batteries for a fleet of electric city buses for a U.S. In the instance of large, mass-transit BEVs such as battery-electric city buses, the case for lighter, non-metallic battery enclosures is even more compelling.ĬW Trending: A New Video Series From CompositesWorld However, lighter composite battery enclosures offer the opportunity to reduce that weight. All of this means that typical metal boxes designed for a BEV can become prohibitively heavy. Moreover, compared to gasoline-powered vehicles, BEVs are often designed differently, as well, with batteries located farther back on the vehicle, which changes overall weight distribution. Thus, a BEV’s battery enclosure needs to offer even more protection. In battery electric vehicles (BEV), the batteries are larger, heavier and more vital to the propulsion of the vehicle. In the case of a gasoline-powered vehicle, the relatively small battery - whose role is mostly to provide electricity for starting the engine and powering accessories such as lights and sound systems - is often protected by a standard metal battery enclosure. All road vehicles have batteries, and all vehicle batteries require protection in case of a crash, vehicle fire or other emergency.
