Charging apparatus

1. A charging apparatus for electrical connection with a charging supply for charging a battery module, the charging apparatus comprising:

a coolant pipe, the coolant pipe providing a passage for a cooling medium and surrounding a space for accommodating the battery module;

a charging terminal for electrically connecting with the charging power supply; and

a chiller connected with the coolant pipe, the chiller being configured to circulate and cool the cooling medium.

2. The apparatus as claimed in claim 1 , further comprising a housing, the housing including a mounting groove for accommodating the battery module.

3. The apparatus as claimed in claim 2 , wherein the coolant pipe is in a wall of the housing.

4. The apparatus as claimed in claim 2 , wherein the housing is configured to contact the battery module and to cool the battery module by conduction.

5. The apparatus as claimed in claim 2 , wherein the charging terminal extends into the mounting groove, the charging terminal being detachably engagable with a terminal of the battery module.

6. The apparatus as claimed in claim 2 , wherein the coolant pipe extends in a circumferential direction around the mounting groove.

7. The apparatus as claimed in claim 2 , wherein:

the coolant pipe extends in a height direction of the mounting groove, and

ends of the coolant pipe are reciprocally connected with each other to be disposed in a zigzag pattern.

8. The apparatus as claimed in claim 2 , wherein a plurality of housings are connected to a single chiller.

9. The apparatus as claimed in claim 2 , wherein:

the mounting groove includes a temperature sensor therein, and

the temperature sensor is connected with a controller, the controller being configured to control flow velocity and temperature of the cooling medium.

10. The apparatus as claimed in claim 2 , wherein an inner surface of the mounting groove includes a heat transfer layer thereon, the heat transfer layer including a material having thermal conductivity as well as having an elasticity greater than an elasticity of the housing.

11. The apparatus as claimed in claim 1 , further comprising a controller detachably connectable with a battery management system (BMS) in the battery module, the BMS being configured to control the battery module and the controller being configured to control flow velocity and temperature of the cooling medium.

12. The apparatus as claimed in claim 1 , wherein the coolant pipe is spirally wound.

13. The apparatus as claimed in claim 1 , further comprising a support member fixed to the coolant pipe, the support member extending in a stacking direction of the coolant pipe to support a shape of the coolant pipe.

14. The apparatus as claimed in claim 1 , wherein the coolant pipe is configured to contact the battery module and to cool the battery module by conduction.

15. A charging apparatus for electrical connection with a charging power supply for charging a battery module, the charging apparatus comprising:

a housing, the housing including a mounting groove for accommodating the battery module and a coolant passage for providing a passage for a coolant, the coolant passage being associated with a wall of the housing;

a charging terminal on the housing and electrically connected with a charging power supply; and

a chiller connected with the coolant passage, the chiller being configured to circulate and cool the coolant.

16. The apparatus as claimed in claim 15 , wherein:

the housing includes an inner wall defining the mounting groove and an outer wall spaced from the inner wall, the outer wall forming an exterior of the housing, and

the coolant passage is between the inner wall and the outer wall.

17. The apparatus as claimed in claim 15 , wherein the coolant passage extends in a circumferential direction around the housing.

18. The apparatus as claimed in claim 15 , wherein an inner surface of the mounting groove includes a heat transfer layer thereon, the heat transfer layer including a material having thermal conductivity as well as an elasticity higher than an elasticity of the housing.

19. The apparatus as claimed in claim 15 , wherein the heat transfer layer includes thermally conductive oil.
