1. A chassis for a battery electric vehicle, comprising:
- a structural frame including first and second parallel sidewalls and a first portion of a vehicle articulation joint;
an electric motor having a first side and a second side, where the first side is parallel to the second side, and the motor is coupled between the first and second parallel sidewalls of the structural frame; and
a thermal interface positioned between the first side of the electric motor and the first sidewall of the structural frame and between the second side of the electric motor and the second sidewall of the structural frame;
wherein an entirety of the first side of the electric motor is in face-sharing contact with the thermal interface positioned between the first side of the electric motor and the first sidewall of the structural frame and an entirety of the second side of the electric motor is in face-sharing contact with the thermal interface positioned between the second side of the electric motor and the second sidewall of the structural frame, and wherein each of the first sidewall and second sidewall of the structural frame includes a respective window cut-out and a plate removably coupled to the window cut-out.
