Problems solved by technology

In this way, for users, different chargers need to be purchased for different battery packs, and it is very inconvenient to carry. In addition, it may also cause the battery pack to be inserted into the wrong charger. If there is no corresponding identification and protection in the charging device system, similar misoperations will cause damage to the battery pack and bring unnecessary losses to users

Embodiment Construction

[0033] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.

[0034] see Figure 1 to Figure 3 , figure 1 It is a circuit schematic diagram of the charging system 100 according to the first embodiment of the present invention. The mark 110 in the figure represents a wireless power transmitting device. Those skilled in the art can easily understand that the wireless power transmitting device includes a power supply 111, a transmitting circuit 112 and a transmitting coil 113. Specifically, the wireless transmitting coil 111 is electrically connected to the transmitting circuit 112. The power supply here generally refers to the AC power supply. After being connected to the AC power supply, the AC power supply is converted into a DC power supply by the AC-DC module (not shown) of the transmitting circuit to supply power for other modules in the circuit. It should be understood that wireless cha...

Abstract

The invention provides a cell packet. The cell packet comprises a wireless power source access unit, a wired power source access unit, a signal detection module, a control unit, at least one chargeable cell used for storing electric energy and realizing outward discharging, and a charging and discharging circuit, wherein an access state of a wired power source or a wireless power source is detected by the control unit through the signal detection module, after electric power access, an electric power channel can be managed by the control unit according to the access state of the wireless electric power and the wired electric power, the charging and discharging circuit comprises a charging circuit used for acquiring electric energy from the wireless power source access unit or the wired power source access unit and charging the chargeable cell. The invention further provided an electric tool employing the cell packet. The cell packet has the wired and wireless charging functions, the cell can be charged in wireless electric power transmission and wired electric power transmission modes, a problem of electric power limit is solved, and charging convenience of the cell is greatly improved.

Description

technical field [0001] The invention relates to a battery pack and an electric tool using the battery pack. Background technique [0002] Electric tools powered by battery packs are mainly charged through chargers with wired interfaces or power connectors, while battery packs are used due to their limited battery life and need to be replaced frequently or charged in time. In many areas, due to the limitations of the environment or usage scenarios, there is no power interface, and the battery pack cannot be charged in time, so it cannot guarantee the needs of working in special environments and for a long time. [0003] On the other hand, since the chemical substances of the battery elements in various battery packs and the nominal voltage of the battery packs are different, it is often necessary to match different charging devices. In this way, for users, different chargers need to be purchased for different battery packs, and it is very inconvenient to carry. In addition, ...
