Description
Technical Field

Background
As the application range of the power tool is expanded, it is widely used in home decoration, outdoor and DIY projects. It generally falls into two categories: wired power tools powered by an ac power source (e.g., an ac power cord) and cordless power tools powered by one or more dc power sources (e.g., a rechargeable battery pack). Wired power tools are typically used in heavy duty applications requiring high power and/or long run times, such as heavy duty sawing, heavy duty drilling and hammering, and heavy duty metalworking. However, in many applications, such as construction sites, finding a continuously available ac power source and/or ac power source faces various problems. Cordless power tools are commonly used for light duty applications, such as drilling, fastening, etc., requiring low or medium power and/or short run times. Cordless tools are generally not accepted by the industry in all applications as they are more limited in their power and/or run time. They are also limited by weight, as higher capacity batteries tend to have greater weight, causing ergonomic disadvantages. Currently, the power devices of rechargeable battery packs can be roughly divided into two categories;

If the electric equipment is alternating current equipment, the electric equipment works in an alternating current mode, whether the current time is a preset first preset time period or not is further judged, and if yes, the user selects the power supply equipment to work in a battery pack power supply/AC power supply mode; if not, the battery pack is preferentially powered to provide electric energy for the electric equipment, the electric quantity of the battery pack is detected and discharged, and when the electric quantity is exhausted, the battery pack is converted into AC power supply for power supply. The battery pack supplies power, namely, the electric energy stored by the battery pack is used for providing alternating current electric energy for the electric equipment, which is referred to as an alternating current mode 2 hereinafter.

In the present embodiment, when the power supply device is discharging (also referred to as "power supply"), the control module samples the battery pack electrically connected thereto, and identifies the type of the battery pack and the capacity of the battery pack.
In one embodiment, the control module samples the battery pack electrically connected to the power supply device during a discharging (also referred to as "power supply") occasion/discharging mode, and identifies the type of the battery pack and the capacity of the battery pack. If the electric quantity of the battery pack is sufficient, the power supply equipment can identify the information of the electric equipment (such as household appliances) electrically connected with the power supply equipment and supply power to the electric equipment; and if the electric quantity of the battery pack is insufficient, the user selects the commercial power supply or finishes the supply. In this embodiment, the power supply device is provided with an ac interface to supply power to a power consumption device (e.g., a household appliance), and the power supply device is provided with a dc interface to supply power to a dc device.

Other user-selected ways will readily occur to those skilled in the art, being simple combinations of logic, not listed here.
In this embodiment, when the power supply device is charged, the control module samples the battery pack electrically connected to the power supply device, and identifies the type of the battery pack and the capacity of the battery pack. The received instruction comprises an instruction sent by a user after the user is connected to the power supply equipment through the intelligent equipment or an instruction preset by the user and stored in the power supply equipment. In the implementation method, if the instruction sent after the user is connected to the power supply equipment through the intelligent equipment is inconsistent with the instruction stored in the power supply equipment and preset by the user, prompt information is sent to remind the user to confirm. In one embodiment, if the instruction sent after the user connects to the power supply device through the smart device is inconsistent with the instruction stored in the power supply device and preset by the user, the instruction sent later is the standard. In the present embodiment, the determination of the amount of power of the battery pack is confirmed based on the sampling of the entire set of voltage values of the battery pack. Taking the MAX voltage of the battery pack as an example for description, if the detected voltage of the battery pack is more than or equal to 20V, judging that the electric quantity is full and charging is not needed; if the detected voltage of the battery pack is less than 20V, judging that the electric quantity is not full and charging is needed; and if the detected voltage of the battery pack is lower than a protection threshold (such as 14V, a prompt message is sent).
