Battery mounting structure for vehicle
A battery mounting structure includes a shear plate and a plurality of separate reinforcement plates. The shear plate extends in a longitudinal direction of the vehicle and includes a first thickness. The reinforcement plates are configured to be disposed between the shear plate and the battery housing assembly and are mounted on an upper surface of the shear plate. The reinforcement plates are spaced apart from each other and include a second thickness. The second thickness is greater than the first thickness.
