[0087] The soft rubber protective cover can be made of soft and elastic and plastic materials such as silica gel and butadiene rubber, so as to avoid dust, sundries and other external obstacles from entering the USB port, thereby affecting the normal operation of the battery pack, and improving the durability and safety of the battery pack.

[0088] In one embodiment, as shown in FIG. 14, a battery pack is provided, which further comprises a user instruction acquisition component 7, the energy storage power supply 3 is connected with the control component 5; the control component 5 is connected with the power port 4 and the user instruction acquisition component 7 respectively; the power port 4 is used for connecting external equipment; the control component 5 is used for controlling the battery pack to enter a working mode according to the wake-up instruction input by the user based on the user instruction acquisition component 7; the working mode includes: the control component 5 detects the connected equipment of the power port 4 in real time, and sends a control instruction to the energy storage power supply 3 to make the energy storage power supply 3 discharge to the power port 4 when the connected equipment is a power consumption equipment.

[0089] The energy storage power supply 3 can be composed of one or more rechargeable battery units. The power port 4 is used for connecting external equipment, and the connected external equipment can include target electric power tools and other power consumption equipment, for realizing physical transmission of electric energy. The target electric power tool can be a tool driven by a transmission mechanism to drive a working head, which can be an electric screwdriver, an electric wrench, an electric drill, etc.

[0090] The user instruction acquisition component 7 can be a button capable of detecting pressing behavior, a touch screen capable of detecting touch behavior, a wireless communication element capable of receiving wireless signals, etc. The user can send a user instruction to the user instruction acquisition component 7 by pressing, touching and sending wireless signals, and the user instruction can be a wake-up instruction of the battery pack.

[0091] The control component 5 controls the battery pack to enter the working mode according to the wake-up instruction input by the user. It can be understood that before the battery pack enters the working mode, the battery pack can be in the sleep mode, and in the sleep mode, the energy storage power supply 3 is disconnected from the power port 4 under the control of the control component 5, so as to reduce unnecessary energy loss and internal circuit damage to the battery pack. When the control component 5 receives the wake-up instruction input by the user, the control component 5 detects the access device of the power port 4 in real time, and controls the energy storage power supply 3 according to the type of the access device. The control instruction sent to the energy storage power supply 3 can be to open the access between the energy storage power supply 3 and the power port 4, so as to realize the discharge of the energy storage power supply 3 to the power port 4.

[0092] It can be understood that the control component 5 can finely control the charging and discharging process of the energy storage power supply 3, which helps to prolong the battery life, prevent overcharging or overdischarging, optimize the use of the battery, and ensure efficient operation under different conditions.

[0093] The battery pack provided in the embodiment can realize the wake-up of the battery pack only when the user input instruction is input, so as to avoid the long-time power-on of the internal circuit during the sleep of the battery pack, thereby achieving the effect of reducing the internal loss of the battery pack.

[0094] In some embodiments, the user instruction acquisition component includes an operation button, and when the battery pack is in the sleep mode, the operation button is used to detect the first pressing operation of the user and generate the wake-up instruction.

[0095] The user instruction acquisition component is an operation button, and the user can trigger the battery pack to start the working mode by pressing the operation button. For example, the first pressing operation can be to generate the wake-up instruction by short pressing or long pressing, or to generate the wake-up instruction according to the number of pressing times or the pressing force, or to determine the preset condition for generating the wake-up instruction according to the combination of the above operation modes.

[0096] The battery pack provided in the embodiment can generate the wake-up instruction by detecting the first pressing operation of the operation button, which can maximize the energy saving and avoid the loss, while ensuring that the user can quickly activate the device when needed, thereby improving the response speed of the battery pack.

[0097] In some embodiments, when the battery pack is in the working mode: the operation button is configured to detect a second pressing operation of the user and generate a sleep instruction; and the control component is further configured to control the battery pack to enter the sleep mode according to the sleep instruction input by the user based on the user instruction acquisition component.

[0098] The second pressing operation can be an operation mode different from the first pressing operation, for example, short pressing, long pressing, different pressing times, different pressing forces, and the like.

[0099] After the control component controls the battery pack to enter the sleep mode according to the sleep instruction input by the user based on the user instruction acquisition component, unnecessary circuits and functions can be turned off, internal circuit paths can be maximally closed on the premise that the user instruction acquisition component can still accept the pressing operation of the user, so that power consumption can be greatly reduced and the battery life can be prolonged.

[0100] The battery pack provided in the embodiment can be flexibly controlled by the user according to actual needs. In the case where the battery pack is not needed to be powered, the user can control the battery pack to enter the sleep mode through simple operation, so that unnecessary power waste can be avoided and the use time of the battery pack can be prolonged.

[0101] In some embodiments, when the battery pack is in the working mode: the control component is configured to detect the access device of the power port in real time, and control the battery pack to enter the sleep mode if no access device is detected within a preset time range.

[0102] The control component can start real-time detection of the access device after receiving the wake-up instruction, so that damage to the circuit caused by real-time detection of the battery pack in the whole time period can be avoided. The real-time detection can be detection of the power port, for example, detection of current change, access signal, and the like.

[0103] If no access device is detected within the preset time range, the battery pack can be controlled to enter the sleep mode, which can be regarded as that no device is accessed to the battery pack within the preset time range, so that the battery pack can be considered to be idle for a long time and the internal circuit of the battery pack can be damaged in the idle state for a long time.

[0104] The battery pack provided in the embodiment can prolong the standby time and the overall service life of the battery pack, reduce power waste caused by forgetting to turn off the battery pack, and improve the energy utilization efficiency.

[0105] In some embodiments, the energy storage power supply includes a preset number of single cells, and the size of the shell matches the size of the preset number of single cells. The preset number of single cells can be arranged in a single row or multiple rows.

[0106] The battery pack provided by the embodiment can avoid waste of internal space by setting a preset number of rechargeable batteries and designing the size of the shell to match the size of the single cells, thereby helping to reduce the volume and weight of the battery pack as a whole and facilitating standardized production of the battery pack.

[0107] In order to more clearly set forth the technical solutions of the present application, a detailed embodiment is further provided. In one embodiment, as shown in FIGS. 1-3, a battery pack 100 is provided, which includes a shell 1, a circuit board 2, an energy storage power supply 3, a power supply port 4, a control assembly 5, a power supply indicator light 6, and a user instruction acquisition assembly 7. The power supply port 4 includes a metal plug-in port 41 and a USB port 42. The shell 1 includes an upper shell 11 and a lower shell 12. The upper shell 11 and the lower shell 12 are detachably connected. As shown in FIG. 4, the side wall edge of the upper shell 11 is provided with a first positioning part 111, and the side wall edge of the lower shell 12 is provided with a second positioning part 121.
