Battery module support arrangement

A chassis arrangement for an electrified heavy vehicle, the chassis arrangement comprising:

• a chassis frame with at least one rail extending in a longitudinal direction of the chassis arrangement;
• a first battery module and a second battery module for propulsion of the heavy vehicle;
• and
• a battery module support arrangement, comprising:
• a pair of triangularly shaped support brackets spaced apart from each other, each of the triangularly shaped support brackets comprising a rail attachment portion for connecting the triangularly shaped support bracket to the longitudinally extending frame rail, and an angled portion extending downwardly between the rail attachment portion and a lower end portion of the triangularly shaped support bracket, the pair of triangularly shaped support brackets comprising a first support bracket and a second support bracket, wherein:
• the first support bracket comprises at least one battery module support portion positioned along the angled portion of the first support bracket, and the second support bracket comprises a pair of battery module support portions positioned along the angled portion of the second support bracket,
• the battery module support portion of first support bracket is arranged at a different position along the angled portion compared to the position of at least one of the battery module support portions of the second support bracket,
• the second support bracket further comprises at least a third battery module support portion arranged along the angled portion, wherein the third battery module support portion is arranged between the pair of battery module support portions,
• the first battery module is configured to be connected to the at least one battery module support portion of the first one of the triangularly shaped support brackets and to the pair of battery module support portions of the second one of the triangularly shaped support brackets, and
• the second battery module is configured to be connected to the third battery module support portion of the second one of the triangularly shaped support brackets;
• wherein the rail attachment portion connects the battery module support arrangement to the rail and wherein the first battery module and the second battery module are supported by the pair of triangularly shaped support brackets at the battery module support portions.
