Title:
BATTERY PACK, ELECTRIC APPLIANCE USING BATTERY PACK, AND ELECTRIC APPLIANCE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/079722
Kind Code:
A1
Abstract:
This battery pack houses first and second cell units that are composed of a plurality of cells, and has a positive electrode power supply terminal 661 and a negative electrode power supply terminal 662. This battery pack is provided with a series connector 664 capable of connecting, in series, the first and second cell units 356, 357 and a parallel connector pair 663 capable of connecting, in parallel, the first and second cell units, and is capable of performing switching between a parallel connection voltage and a series connection voltage. For this switching, a series-parallel switch terminal 683 is added to a high-voltage electric appliance body. In the case of attachment to the high-voltage electric appliance body, the series connector 664 becomes conductive and the parallel connector pair 663 is cut off by the action of the series-parallel switch terminal 683. In the case of attachment to a low-voltage electric appliance body, the state is returned to an initial state, the series connector 664 is cut off, and the parallel connector pair 663 becomes conductive.
