Claim 15:
16. A method of mounting a protection device in a motor vehicle with electric or hybrid drive comprising a power supply battery, the method comprising:
supplying the power supply battery and at least one protection device, wherein the at least one protection device is configured to protect a functional element of the motor vehicle against lateral shocks and comprises, in a single piece, a protection element and a shock absorber, and the functional element comprises the power supply battery; and
on at least one of two left and right sides of the motor vehicle, fixing, removably, a first protection device to a corresponding lateral edge of the power supply battery and to an underframe of the motor vehicle, such that the protection element at least partly covers a bottom surface of the power supply battery, the shock absorber is arranged, in a longitudinal direction of the motor vehicle, between a front support element of a support of the power supply battery and a fixing portion of a rear end of the motor vehicle, and, in a transverse direction of the motor vehicle, against a lateral edge of the power supply battery,
wherein the shock absorber includes a first lateral portion, a second lateral portion, and a top portion,
wherein the first lateral portion and the second lateral portion extend from a top surface of the protection element substantially at right angles to the top surface,
wherein the top portion is in contact with ends of the first lateral portion and the second lateral portion opposite ends of the first lateral portion and the second lateral portion in contact with the top surface of the protection element,
wherein the top portion extends substantially at right angles to the first lateral portion and the second lateral portion,
wherein the top portion of the shock absorber is concave on a side opposite that facing the top surface of the protection element, and
wherein a height of the shock absorber varies such that a vertex of the top portion has a smallest height and outer edges of the top portion have a largest height.
