System, method, and apparatus for power distribution in an electric mobile application using a combined breaker and relay

A mobile application, comprising:

• a motive power circuit, the motive power circuit comprising a power storage device and an electrical load, wherein the power storage device and the electrical load are selectively electrically coupled through a power bus;
• a power distribution unit (PDU) electrically interposed between the power storage device and the electrical load, wherein the PDU comprises a breaker/relay positioned on one of a high side and a low side of the power storage device;
• wherein the breaker/relay comprises:
• a fixed contact electrically coupled to the power bus;
• a movable contact selectively electrically coupled to the fixed contact, and wherein the movable contact allows power flow through the power bus when electrically coupled to the fixed contact, and prevents power flow through the power bus when not electrically coupled to the fixed contact;
• an armature operationally coupled to the movable contact, such that the armature in a first position prevents electrical coupling between the movable contact and the fixed contact, and the armature in a second position allows electrical coupling between the movable contact and the fixed contact;
• a first biasing member biasing the armature into one of the first position or the second position;
• and
• a means for adjusting a contact force value of the movable contact during run-time operations of the motive power circuit, wherein the contact force biases the movable contact into electrical coupling with the fixed contact.
