PROTECTIVE STRUCTURE OF AN ELECTRIC BATTERY AND A MOTOR VEHICLE COMPRISING SUCH A PROTECTIVE STRUCTURE

A protective structure of an electric battery in a motor vehicle having a longitudinal axis, a transverse axis, and a vertical axis. The protective structure includes a support crossmember and a protector together defining a housing for accommodating an electric battery. The protector includes at least a first defense flange configured to deform by dissipating energy under the application of a force along the longitudinal axis. The protector also includes an upper connecting strip connected at least to the first defense flange. The protective structure also includes at least four screwed fastenings to connect the protector to the support crossmember, the defense flange having a first dimension along the longitudinal axis, at least 10% greater than the dimension of the electric battery along the longitudinal axis.
