Embodiment Construction

[0043] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] Such as figure 1 As shown, the handheld electric tool charging and discharging system includes an electric tool 100 for performing construction operations on construction objects, a battery assembly 200 that can be recharged and discharged cyclically, and a charger 300 . Wherein, the charger 300 provides charging power for the battery pack. After the battery pack 200 is fully charged, the battery pack 200 is placed in the electric tool 100. According to the control of the power switch on the electric tool 100, the battery pack 200 is the The motor and other components inside provide power, so as to realize the normal operation of the electric tool 100 .

[0045] combined reference figure 2Taking an electric drill as an example, the electric tool 100 includes a main body 101 and a handle 102, wherein the main...

Abstract

The invention discloses a battery assembly of a handheld electric tool, which comprises at least two battery units connected in sequence and a plurality of first connecting ports, and the first connecting ports comprise a positive port, a negative port and a battery detection port, wherein the positive electrode port and the negative electrode port are the head end and the tail end of the batteryunit which are connected in sequence, and the battery detection port is used for detecting charging and discharging parameters of the battery unit by an electric tool or a charger and controlling charging and discharging of the battery assembly according to the detected charging and discharging parameters. The invention further discloses a handheld electric tool and a charging base. According to the invention, the structure of the battery assembly of the hand-held electric tool is improved, and the charger and the hand-held electric tool realize monitoring of battery parameters in the workingprocess of the battery assembly only through the plurality of connecting ports, so that the cost of a charging and discharging system of the hand-held electric tool is greatly reduced. And the charging safety is ensured, and the service life of the battery assembly is prolonged.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a hand-held electric tool, a battery assembly thereof, and a charging stand. Background technique [0002] Hand-held electric tools, as the name suggests, are electric tools that are operated by hand or hanging, and are often used in construction, such as electric drills, wrenches, electric saws, electric hammers, etc. The electric tool provides power for the motor of the electric tool through a built-in rechargeable battery, so as to control the rotation of the motor and carry out construction on the construction object. [0003] Due to the portability of the electric tool, it brings great convenience to construction workers. However, in order to ensure the use requirements of the electric tool, the existing electric tool needs to be equipped with two battery packs and a charger, which is costly and has a short service life of the battery pack. Contents of the inve...
