Description

Power supply equipment and control method thereof

This application claims the priority of the Chinese patent application whose application date is November 04, 2019 and the application number is 201911065646.7, the entire content of which is incorporated into this application by reference.

Technical field

The invention relates to a power supply device, in particular to a power supply device with multiple functions and a control method thereof.

Background technique

With the expansion of the application range of power tools, they are widely used in home decoration, outdoor and DIY projects. They are generally divided into two categories: wired power tools powered by AC power sources (such as AC power cords) and cordless power tools powered by one or more DC power sources (such as rechargeable battery packs). Wired power tools are generally used for heavy-duty applications that require high power and/or long-term operation, such as heavy-duty sawing, heavy-duty drilling and hammering, and heavy-duty metal processing. 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 usually used for light-load applications that require low or medium power and/or short running time, such as drilling, fastening, etc. Since cordless tools are often more restricted in terms of their power and/or running time, they are generally not accepted by the industry in all applications. They are also limited by weight, because higher capacity batteries tend to have a heavier weight, resulting in ergonomic disadvantages. At present, the power devices of rechargeable battery packs can be roughly divided into two categories;

Type 1, backpack type power device, which contains multiple lithium batteries inside. It can only provide a single DC voltage (for example: 36V) to power the electric tool; and the battery is installed inside the electric device and cannot be detached to supply power to the second electric device.

The other type is the power device, which includes the device body, multiple batteries (also called battery packs) of the same specification that can be plugged in the body, which can be AC input (charging, power supply), AC output or DC output, and the battery Remove to supply power to the second electrical device. However, it cannot be controlled flexibly (such as without power management control) to optimize the application of electrical energy. Manual operation by the user is required for use. The user experience is not good.

Generally speaking, a traditional power tool battery pack may not be able to operate a traditional wired power tool or other wired electronic equipment, and unconverted AC power may not be used to operate a cordless power tool.

Wherein, the above instruction includes one or a combination of the following: configuring the working status of a plurality of battery packs in the power supply device; charging time information of the power supply device; power supply time information of the power supply device;

The power supply device can work in AC mode or DC mode during power supply operation, where the AC mode refers to the power supply device providing AC power to the power consuming device, for example, the power supply device uses the power of the AC power source to directly provide AC power to the power consuming device, or The power supply device uses the electric energy stored in the battery pack to provide AC power to the electric device; the DC mode means that the power supply device uses the electric energy stored in the battery pack to provide the electric device with DC power.

The power supply equipment includes at least one electrical energy output port, which is connected to the electrical equipment. It can be only one electrical energy output port that outputs DC electrical energy or AC electrical energy. It can be two different electrical energy output ports, one output direct current electrical energy, and the other Output AC power. The electrical equipment includes AC equipment and DC equipment powered by city power, such as household appliances, AC power tools, and DC equipment such as DC power tools, which can be powered by installing the battery pack to work.

During the charging operation of the power supply device, the battery pack is charged by using the AC power input from the AC input port.

In this way, when using the power supply device of the above embodiment, the user connects to it through the smart device, and on the one hand, performs charging management settings, such as charging time reservation management: schedule a certain period of time to charge the power supply device, for example, set the first preset Set charging within a time period, the economic benefit of charging in this time period is high, set the second preset time period, the power supply equipment can be charged or not charged in this time period; for example, the battery pack use reservation, reservation certain What number of battery packs will the user use at any time. At this time, the reserved battery pack will not supply power to the powered device, and the power supply device will automatically detect whether the battery pack is full or not. If it is dissatisfied, it will automatically be fully charged until it can be used by the user. Cut off the electrical connection with the power supply equipment to avoid the danger during disassembly.

The power supply device is in the discharge/discharge mode to identify the type of the electrical device. If the electrical device is a DC device, it works in the DC mode and uses The electrical energy stored in the battery pack provides electrical energy to the electrical equipment. If the electric device is an AC device, it works in AC mode, and it is further judged whether the current time is the first preset time period.

The AC power supply, that is, the use of AC power (mains) power to directly provide AC power to the electrical equipment, hereinafter referred to as AC mode 1, the battery pack power supply, that is, the use of the electrical energy stored in the battery pack to provide AC to the electrical equipment Electric energy, hereinafter referred to as AC mode 2. User selection includes smart selection, manual selection and real-time selection. At the beginning of the use of the power supply device, the user can configure the power supply device to work in the AC mode in the first preset time period through the smart device, such as setting smart Select, the default is the priority AC mode 1-AC power supply, if it is detected that the power supply device is not connected to the mains, it will switch to the AC mode 2-battery pack power supply; if the manual selection is set, the user has selected one of them in advance Working mode, such as the default only exchange mode 1; if the real-time selection is set, the power supply device immediately sends instructions to the smart device to solicit the user's choice in real time.
