Abstract
Provided is a battery that may include a first terminal or cable, a second terminal or a cable, a thermal fuse configured to connect to the first terminal or cable and the second terminal or cable, a first sleeving layer that is disposed on the thermal fuse, and that is configured to muffle an arc explosion of the thermal fuse and encapsulate molten material generated by the arc explosion of the thermal fuse, and a second sleeving layer that is disposed on the first sleeving layer, and that is configured to encapsulate the molten material generated by the arc explosion of the thermal fuse that penetrates the first sleeving layer. An overcurrent protection system and a sleeving are also provided.
Claims17
A battery, comprising:
- a first terminal;
- a second terminal;
- a thermal fuse configured to connect to the first terminal and the second terminal;
- a first sleeving layer that is disposed on the thermal fuse, and that is configured to muffle an arc explosion of the thermal fuse and encapsulate molten material generated by the arc explosion of the thermal fuse;
- and
- a second sleeving layer that is disposed on the first sleeving layer, and that is configured to encapsulate the molten material generated by the arc explosion of the thermal fuse that penetrates the first sleeving layer,
- wherein the battery comprising two or more electrochemical cells, the first terminal is a terminal of a first electrochemical cell and the second terminal is a terminal of a second electrochemical cell.
An overcurrent protection system for a battery, the overcurrent protection system comprising:
- a thermal fuse configured to connect to a first terminal and a second terminal of the battery;
- a first sleeving layer that is disposed on the thermal fuse, and that is configured to muffle an arc explosion of the thermal fuse and encapsulate molten material generated by the arc explosion of the thermal fuse;
- a second sleeving layer that is disposed on the first sleeving layer, and that is configured to encapsulate the molten material generated by the arc explosion of the thermal fuse that penetrates the first sleeving layer;
- a first end cover that covers a first opening of the first sleeving layer and the thermal fuse;
- and
- a second end cover that covers a second opening of the first sleeving layer and the thermal fuse.
An overcurrent protection system for a battery comprising:
- a thermal fuse configured to connect to a first cable and a second cable of the battery;
- a first sleeving layer that is disposed on the thermal fuse, and that is configured to muffle an arc explosion of the thermal fuse and encapsulate molten material generated by the arc explosion of the thermal fuse;
- a second sleeving layer that is disposed on the first sleeving layer, and that is configured to encapsulate the molten material generated by the arc explosion of the thermal fuse that penetrates the first sleeving layer;
- a first end cover that covers a first opening of the first sleeving layer and the thermal fuse;
- and
- a second end cover that covers a second opening of the first sleeving layer and the thermal fuse.
