Abstract

This application relates to the field of battery manufacturing technologies and provides a battery formation and grading device including: a box having an accommodating space; a temperature control apparatus, provided on the box, including a semiconductor cooling sheet, where two opposite sides of the semiconductor cooling sheet are configured as a cooling surface and a heating surface, the cooling surface being arranged facing the inside of the box and the heating surface being arranged facing the outside of the box. The technical solution of this application improves the efficiency of temperature control inside the battery formation and grading device and reduces the cost of temperature control.

First claim

The invention claimed is:

1. A battery formation and grading device comprising:
a box having an accommodating space; and
a temperature control apparatus, provided on the box, comprising a semiconductor cooling sheet, wherein two opposite sides of the semiconductor cooling sheet are configured as a cooling surface and a heating surface, the cooling surface being arranged facing the inside of the box and the heating surface being arranged facing the outside of the box, wherein
the temperature control apparatus further comprises:
a first fan and a second fan, wherein the first fan is provided on the cooling surface and is configured to blow air into the box, and the second fan is provided on the heating surface and is configured to blow air outside of the box;
a first heat sink disposed between the cooling surface and the first fan and fitting with the cooling surface; and
a second heat sink disposed between the heating surface and the second fan and fitting with the heating surface; and
the first heat sink is provided with a first thermal insulation layer on a side facing the second heat sink; and
the second heat sink is provided with a second thermal insulation layer on a side facing the first heat sink.

2. The battery formation and grading device according to claim 1 , wherein the first heat sink is bonded to the cooling surface and the first fan is fixedly connected to the first heat sink via a first fastener; and/or,
the second heat sink is bonded to the heating surface and the second fan is fixedly connected to the second heat sink via a second fastener.

3. The battery formation and grading device according to claim 1 , wherein the first heat sink and/or the second heat sink comprises a sheet heat sink or a honeycomb heat sink.

4. The battery formation and grading device according to claim 1 , wherein the battery formation and grading device further comprises: a temperature sensor disposed in the box and configured to monitor temperature in the box; and
a controller electrically connected to the temperature sensor, the first fan, and the second fan.

5. The battery formation and grading device according to claim 1 , wherein the box comprises: a top barrier plate, a bottom barrier plate, and a side plate assembly arranged between the top barrier plate and the bottom barrier plate to form an enclosure, and
the temperature control apparatus is provided on the top barrier plate and/or the side plate assembly.

6. The battery formation and grading device according to claim 5 , characterized in that the side plate assembly comprises a first side plate, a second side plate, a third side plate, and a fourth side plate connected in sequence, wherein
the first side plate and the third side plate are opposite each other, and the second side plate and the fourth side plate are opposite each other, with one of the first side plate and the second side plate provided with a fore door and the other one provided with an inlet/outlet for battery transporting.

7. The battery formation and grading device according to claim 5 , wherein the top barrier plate, the bottom barrier plate, and the side plate assembly are all flame retardant plates.

8. The battery formation and grading device according to claim 1 , wherein the battery formation and grading device further comprises:
a rack disposed in the accommodating space for battery supporting;
a formation apparatus disposed in the accommodating space; and
a grading apparatus disposed in the accommodating space.
