Abstract: A power distribution apparatus includes a base including an interface area, a high-voltage connection part and a low-voltage connection part fixed in the interface area. The power distribution apparatus further includes a high-voltage loop at least partially disposed on the base, being electrically connected with the high-voltage connection part, and having a battery positive-electrode connection end and a battery negative-electrode connection end. The components connected in the high-voltage loop is electrically connected to each other. The high-voltage loop includes a disconnecting switch core fixed on the base. A circuit board is disposed on the base, and a low-voltage loop is integrated into the circuit board. The high-voltage loop and the low-voltage connection part are plugged into the circuit board and electrically connected to the low-voltage loop.
