High voltage distribution module for electric vehicle

A power distribution system to distribute electricity for low-current vehicular components using a low-current and high-current vehicular components using a high-current, comprising:

• a housing including a low-current wall and a high-current wall;
• wherein the low-current wall extends opposite to the high-current wall;
• low-current terminals configured to regulate the low-current for the low-current vehicular components;
• high-current terminals configured to regulate the high-current for the high-current vehicular components;
• wherein the low-current terminals and the high-current terminals are mounted on opposite sides of the housing;
• wherein all of the low-current terminals are mounted to the low-current wall;
• wherein all of the high-current terminals are mounted to the high-current wall;
• a power bus configured to carry the high current;
• wherein the power bus includes one or more bus bars;
• wherein the bus bars extend parallel to the high-current wall;
• wherein the bus bars are positioned proximal to the high-current wall;
• wherein the bus bars includes a positive bar and a negative bar arranged in a stacked arrangement;
• wherein the high-current terminals are electrically coupled to the power bus;
• a power distribution unit (PDU) electrically connected to the bus bars;
• an ancillary expansion board (AEB) electrically connected to at least one of the low-current terminals;
• wherein the PDU is configured to communicate with the AEB;
• and
• wherein the PDU and AEB are positioned proximal to the low-current wall.
