Vehicle chassis supporting power supply module

A vehicle, comprising:

• a first chassis rail extending in a longitudinal orientation of the vehicle and comprising:
• a first medial side facing towards a longitudinal midline of the vehicle,
• a first lateral side facing away from the longitudinal midline of the vehicle,
• a first bottom margin,
• a first cutout that, along at least a part of a first section of the first chassis rail, extends through the first bottom margin and into at least a portion of the first medial side and into at least a portion of the first lateral side;
• a second chassis rail extending in the longitudinal orientation of the vehicle and comprising:
• a second medial side facing the longitudinal midline of the vehicle,
• a second lateral side facing away from the longitudinal midline of the vehicle,
• a second bottom margin,
• a second cutout that, along at least a part of a second section of the second chassis rail, extends through the second bottom margin and into at least a portion of the second medial side and into at least a portion of the second lateral side;
• one or more power-supply mounting brackets affixed to the first chassis rail and to the second chassis rail;
• and
• a power supply module affixed via the one or more power-supply mounting brackets, and positioned at least partially beneath the first chassis rail and the second chassis rail, and at least partially in a first space associated with the first cutout and a second space associated with the second cutout.
