The AC module includes an AC mounting base 2 and a slotted terminal 3 arranged inside the AC mounting base 2. The slotted terminal 3 includes a copper tube 4 which is hollow. A plurality of insertion slots 5 are formed in the inner wall of one end of the copper tube 4, and the plurality of insertion slots 5 are evenly distributed along the circumferential direction of the copper tube 4. The traditional terminal is replaced with the slotted terminal 3. The inner wall of the slotted terminal 3 is provided with the insertion slots 5. A protrusion is arranged in the charging hole of the charging plug. After the slotted terminal 3 is inserted into the charging plug, the protrusion of the charging plug is adapted to be in the insertion slots 5. The protrusion on the charging plug is also made of copper material. By using the elasticity of the copper tube 4 and the elasticity of the protrusion, the protrusion is in interference fit in the insertion slots 5, improving the connection strength between the charging plug and the slotted terminal 3, making the connection between the cable and the socket more stable, and improving the seismic performance. Similarly, the terminal in the DC module is also replaced with the slotted terminal 3, increasing the stability of the electrical connection of the DC module, while the other structures of the DC module and the AC module remain unchanged.
