wherein the battery frame assembly is coupled to the first side member and the second side member such that each battery pack is positioned partially below the first side member or the second side member when the battery pack is installed in the electric vehicle, and
wherein the battery frame assembly comprises an underframe assembly positioned below the first side member and the second side member, the underframe assembly comprising at least one transversely extending push bar assembly.
9. The electric vehicle of claim 8 , wherein the battery frame assembly further comprises:
a first row of battery pack receptacles comprising a first battery pack receptacle outboard of the first side member;
a second battery pack receptacle inboard of the first side member and the second side member; and
and a third battery pack receptacle outboard of the second side member.
10. The electric vehicle of claim 9 , wherein the battery frame assembly further comprises:
a second row of battery pack receptacles comprising a fourth battery pack receptacle adjacent to the first battery pack receptacle in a longitudinal direction;
a fifth battery pack receptacle adjacent to the second battery pack receptacle in the longitudinal direction;
and a sixth battery pack receptacle adjacent to the third battery pack receptacle in the longitudinal direction.
11. The electric vehicle of claim 10 , wherein the battery frame assembly further comprises:
a third row of battery pack receptacles comprising a seventh battery pack receptacle adjacent to one of the first battery pack receptacle or the fourth battery pack receptacle in the longitudinal direction;
an eighth battery pack receptacle adjacent to one of the second battery pack receptacle or the fifth battery pack receptacle in the longitudinal direction; and
a ninth battery pack receptacle adjacent to one of the third battery pack receptacle or the sixth battery pack receptacle in the longitudinal direction.
12. The electric vehicle of claim 8 , wherein a topmost portion of the battery frame assembly is flush with a topmost portion of the first side member and the second side member.
13. The electric vehicle of claim 8 , wherein the battery frame assembly further comprises an impact plate outboard of each battery pack receptacle of the plurality of battery pack receptacles.
14. An electric vehicle, comprising:
a chassis comprising a first side member and a second side member; and
a battery frame assembly coupled to the first side member and the second side member and defining a plurality of battery pack receptacles configured to receive a battery pack;
wherein each battery pack receptacle of the plurality of battery pack receptacles includes an upper opening configured to allow the battery pack to be lowered into or lifted out of the battery frame assembly to install or remove the battery pack while the electric vehicle is in an operable orientation,
wherein the battery pack is configured to be installed in the battery frame assembly by a first fastener located near a first corner of the battery pack and a second fastener located near a second corner of the battery pack, and
wherein the first fastener and the second fastener are configured to be inserted or removed from the battery pack in a vertical direction.
15. The electric vehicle of claim 14 , wherein the battery pack comprises a plurality of mounting elements configured to support a weight of the battery pack to install or remove the battery pack.
