Document Type and Number:
WIPO Patent Application WO/2024/093303
Kind Code:
A1
Abstract:
Disclosed in the present invention are an electric tool and a discharging system. A battery pack comprises a first positive terminal, a first negative terminal, a first controller, and a first state detection terminal. The electric tool comprises a second positive terminal, a second negative terminal, a second controller, a power supply module for supplying power to the second controller, and a power-on module connected to the power supply module. When the battery pack is connected to the electric tool by insertion, the power-on module is connected to the first state detection terminal; and the first state detection terminal controls on/off of the power-on module according to the state of the battery pack, so as to control whether to power on the electric tool. According to the present invention, by directly connecting the state detection terminal of the battery pack to the power-on module of the electric tool, when an anomaly occurs in the battery pack, the power-on module can be controlled not to be powered on, i.e., the tool is not powered on, so that anomaly protection can be carried out in time, and no loss would be caused when an anomaly occurs in the battery pack.
