BATTERY PACK AND ELECTRIC APPARATUS USING SAME

WIPO Patent Application WO/2020/090670

A1

The purpose of the present invention is to obtain a battery pack which is adapted to transport regulations and capable of providing high output. The battery pack is provided with cell units 180 and 190, a switching element 171 connected in series between the cell units, and a control circuit (switching element 163) for operating the switching element 171. The battery pack is configured such that, when not in operation, the cell units 180 and 190 are electrically separated from each other. When an external apparatus power supply signal has been transmitted via a D-terminal 134, the control circuit causes the switching element 171 to conduct, whereby a voltage of the series connection of the cell units 180 and 190 is output to a positive-pole output terminal 133 and a negative-pole output terminal 134. When the external apparatus power supply signal is lost, the switching element 171 is shut down after a short time of delay due to a capacitor 172.
