The utility model discloses an end plate structure of a light-weight battery module, which is characterized by comprising a module end plate of the battery module, the module end plate comprises an inner layer plate and an outer layer plate, an energy absorption sandwich layer is arranged between the inner layer plate and the outer layer plate, and the energy absorption sandwich layer is of a honeycomb array structure. The axes of honeycomb holes of the honeycomb array of the energy absorption sandwich layer are perpendicular to the inner layer plate and the outer layer plate; a first end anda second end are respectively arranged at two ends of the energy-absorbing sandwich layer; by adopting the sandwich design and the hot pressing technology for forming, the upper end face and the lowerend face are made of high-strength aluminum, the aluminum honeycomb is adopted as the middle sandwich, the structural rigidity is improved while the weight is reduced, the end contact surfaces are increased through the struct
