Abstract

Provided are a battery pack and an electrical apparatus by which information can be transmitted at an appropriate timing from the battery pack to a device body. A battery pack (10) includes: a serial communication reception circuit (31) and a temperature information transmission circuit (32); an LS terminal that is selectively connected to the serial communication reception circuit (31) or the temperature information transmission circuit (32); a first switching circuit (21) that is provided between the LS terminal and the serial communication reception circuit (31) and the temperature information transmission circuit (32); and a V terminal that is connected to the first switching circuit (21). The first switching circuit (21) switches between connecting the serial communication reception circuit (31) or the temperature information transmission circuit (32) to the LS terminal according to a signal inputted from the V terminal.

Dependent claims

An electrical apparatus comprising a battery pack, a device body connected to the battery pack, and a first terminal configured to send and/or receive an analog signal and a digital signal,

wherein when one of the device body and the battery pack transmits a predetermined signal to the other of the battery pack and the device body, the other of the battery pack and the device body is switched from one of the analog signal and the digital signal to the other of the analog signal and the digital signal and transmits a signal indicating an information of the other of the battery pack and the device body to one of the device body and the battery pack via the first terminal,
wherein the battery pack comprises:
a plurality of first communication circuits;
a first battery-side communication terminal selectively connected to any one of the plurality of first communication circuits;
a first switching circuit provided between the plurality of first communication circuits and the first battery-side communication terminal;
and
a battery-side switching terminal connected to the first switching circuit,
wherein the first switching circuit switches among the plurality of first communication circuits to be connected to the first battery-side communication terminal according to the predetermined signal input from the battery-side switching terminal.
