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.
