Connecting and integrating electrical systems

An integrated electrical system, comprising:

• a wheeled chassis extending longitudinally between a front wheel and a rear wheel;
• at least one electric propulsion motor operatively coupled to at least one of the front wheel or the rear wheel of the wheeled chassis;
• a battery pack electrically coupled to the electric propulsion motor;
• a body comprising:
• a storage compartment extending along the wheeled chassis between a front end and a rear end;
• a powered tailgate connected to the rear end of the storage compartment;
• and
• a plurality of electric-motor-driven components actuatable to move relative to the storage compartment;
• and
• a DC-DC converter electrically coupled to the battery pack, the DC-DC converter configured to receive electrical power from the battery pack at an input DC voltage and to provide power to the plurality of electric-motor-driven components at one or more output DC voltages that are lower than the input DC voltage,
• wherein the battery pack and the DC-DC converter are co-located in a space defined by the front wheel and a longitudinal midpoint of the wheeled chassis.
