Abstract
An electric vehicle battery pack cover with a fiber reinforced multiple-ply composite body whose bottom surface is coated with a high-hardness, high-melting point, and fire- and abrasion-resistant coating. The coating can be any one or more materials that provide sufficient fire and abrasion resistance to allow the battery pack to contain a battery fire. As examples, the coating can be a nickel layer, a steel layer, a high temperature mineral layer such as a mica layer, or any combination of these materials. The composite body can be any composite body that is both compatible with the fire- and abrasion-resistant coating and provides sufficient strength to act as a battery cover. As examples, the composite body can be made of one or more glass fiber plies, carbon fiber plies, aramid fiber plies, or any combination of any number of these plies, with a crosslinked polymer or other matrix.
