Abstract
The invention relates to a traction battery (1) for a motor vehicle, having at least one cell assembly (2) with a plurality of battery cells (3) and having a battery housing (5) with a plurality of housing walls (6a, 6b, 6c, 6d, 6e, 6f) which enclose a housing interior (4) for receiving the at least one cell assembly (2), wherein at least one battery housing part of the battery housing (5), which battery housing part is subject to an accident-induced force, has at least one protruding portion (14) which projects outward in the direction of an area surrounding the traction battery (1) and, for the purpose of protecting the at least one cell assembly (2), is designed to absorb the accident-induced force. The invention also relates to a motor vehicle.
