[0023] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] See Figures 1 to 4 This utility model provides an outdoor energy storage device, including a device body 100, an energy storage component 200, a power distribution unit 300, a charging interface 400, and at least one discharging interface 500. The device body 100 includes a shell, which is composed of multiple outer side walls forming a sealed space. The energy storage component 200 and the power distribution unit 300 are disposed within the sealed space. The energy storage component 200 is used to store electrical energy so as to supply power to the outside. The power distribution unit 300 is used to distribute the power supplied by the energy storage component 200, and includes a positive terminal connection portion 310 and a negative terminal connection portion 320. The positive terminal connection portion 310 is provided with a positive output... The device has an input port and multiple positive output ports. The positive input port is electrically connected to the positive terminal of the energy storage component 200. The negative connection portion 320 is provided with a negative input port and multiple negative output ports. The negative input port is electrically connected to the negative terminal of the energy storage component 200. The charging interface 400 and the discharging interface 500 are both provided on the device body 100 and exposed on the outside of the device body 100. The charging interface 400 is electrically connected to one of its positive output ports and one of its negative output ports. The discharging interface 500 is electrically connected to another positive output port and another negative output port. The output ports connected to the charging interface 400 and each discharging interface 500 are different.

[0025] In this embodiment, the power distribution unit 300 can be implemented as a terminal block with a circuit input terminal and multiple circuit output terminals. A positive input port and a negative input port are located on the circuit input terminal, and multiple positive output ports and multiple negative output ports are located on the multiple circuit output terminals. Each positive output port is paired with a negative output port and located on one of its circuit output terminals to connect the charging interface 400 and each discharging interface 500. Further, the power distribution unit 300 includes an electronically controlled switch located in the terminal block to control the on / off state of each circuit output terminal. The energy storage assembly 200 includes a BMS system 210 (Battery Management System) and a power module 220 connected to the BMS system 210. The BMS is electrically connected to the power distribution unit 300 and is used to control the power output of the power module 220 and the on / off state of each circuit in the power distribution unit 300. For example, by controlling the electronically controlled switch, the connection between the charging circuit connected to the charging interface 400 and the discharging circuit connected to the discharging interface 500 can be further controlled.

[0026] The outdoor energy storage device also includes a fast-charging output component 600, which enables the fast-charging function of the outdoor energy storage device. The fast-charging output component 600 includes a fast-charging power conversion module 610 and a fast-charging interface 620. The fast-charging interface 620 is also exposed on the outside of the device body 100 for electrical connection with corresponding electronic products. The fast-charging power conversion module 610 implements the fast-charging circuit, including a fast-charging protocol chip, a step-down circuit, and a heat dissipation component. The fast-charging protocol chip can be located within the BMS system 210 or as an independent component within the device body 100. It utilizes fast-charging protocols such as QC (Qualcomm Quick Charge) and PD (USB Power) to achieve protocol communication with the connected electronic products, thereby executing the fast-charging scheme. This structure has been implemented in the prior art. In this embodiment, the fast-charging power conversion module 610 uses a PD fast-charging module, but other fast-charging modules can also be used, all within the scope of this embodiment. The fast charging power conversion module 610 is connected to one of its positive output ports and one of its negative output ports. The fast charging interface 620 is connected to the output terminal of the fast charging power conversion module 610. The two are connected by an electronic control switch to control the output of the fast charging circuit.

[0027] Compared with the prior art, the outdoor energy storage device provided by this utility model adds a fast charging output component 600, which can be matched with mobile phones, laptops, tablets and other electronic products with fast charging functions. It significantly shortens the charging time of such electronic products, avoids charging occupying too much time of the outdoor energy storage device, and eliminates the need to carry additional inverter components and charging components and other corresponding charging components adapted to the corresponding electronic products with fast charging functions. It reduces the resources occupied by charging on the outdoor energy storage device, shortens the charging time of related electronic products, and does not affect the use of other electronic devices, significantly improving the user experience.

[0028] In one embodiment, the fast charging power conversion module 610 includes a fast charging voltage / current conversion unit and a buck unit. The fast charging voltage / current conversion unit is used to adapt the voltage / current to the voltage / current required for fast charging. It includes a synchronous rectifier MOSFET (metal-oxide-semiconductor transistor) and an output filter capacitor. The synchronous rectifier MOSFET will efficiently rectify the voltage and current output from the BMS system 210. The rectified pulse DC is smoothed by the output filter current to ensure that the current output to the mobile phone is pure and stable. The step-down unit reduces the voltage flowing from the energy storage component (BMS system 210 in this embodiment) to the fast-charging voltage / current conversion unit, ensuring that the voltage output from the energy storage component matches the voltage required by the fast-charging voltage / current conversion unit. For example, if the voltage output from the energy storage component 200 via the power distribution unit 300 is 24V, and the voltage output from its discharge interface 500 in this embodiment is also 24V, the voltage reaching the step-down unit is also 24V. The step-down unit then converts the 24V to 9V or 12V, etc., to match the output of the fast-charging voltage / current conversion unit, ensuring that the output of the fast-charging voltage / current conversion unit is compatible with electronic products such as mobile phones. The step-down unit may include multiple transformers to convert the voltage to the appropriate voltage flowing to the fast-charging voltage / current conversion unit according to the control requirements of the fast-charging protocol chip, ensuring compatibility with the corresponding electronic product. Compared with existing fast charging components such as fast chargers, this embodiment reduces the primary switching MOSFET structure for converting 220V AC power, thereby reducing costs and achieving fast charging functionality. Of course, the fast charging power conversion module 610 in this invention can also be configured with a structure similar to that of an on-board fast charging module in the prior art, which has already been implemented in the prior art and is within the scope of this invention.

[0029] Furthermore, both the discharge port 500 and the fast charging port 620 are DC power output terminals used to output DC power. The voltage output by the discharge port 500 can be set to 24V, 12V, or other values ​​according to usage requirements.

[0030] In another embodiment, the power module 220 includes a plurality of power components 221 and an electrical connection plate 222 connecting the plurality of power components 221. The plurality of power components 221 are arranged on the same plane and disposed in an enclosed space within the device body 100. Each power component 221 includes a plurality of adjacently arranged battery cells 223, and each battery cell 223 is provided with a positive terminal and a negative terminal, such as... Figure 4As shown, the battery cells 223 in each power supply component 221 are arranged in a 2*9 planar pattern. Between two adjacent power supply components 221, the positive terminal of the battery cell 223 of one power supply component 221 is on the same side as the negative terminal of the battery cell 223 of the other power supply component 221, and the negative terminal of the battery cell 223 of one power supply component 221 is on the same side as the positive terminal of the battery cell 223 of the other power supply component 221. For example, for two power supply components 221 located at the rear of the device body 100, the upper end of the rear power supply component 221 is the negative terminal and the lower end is the positive terminal, while the upper end of the front power supply component 221 is the positive terminal and the lower end is the negative terminal. This arrangement allows the power supply components 221 to be staggered within the device body 100, making the power supply structure design more reasonable and avoiding problems such as local overheating. The battery cells 223 store chemical energy storage materials, such as lithium iron phosphate, and are connected in series to form the power supply terminals of the energy storage assembly 200.

[0031] Specifically, multiple electrical connection plates 222 are provided, each made of a conductive material such as copper, aluminum, or iron. Each electrical connection plate 222 is disposed between two adjacent power supply components 221 and electrically connected to the negative terminals of the battery cells 223 of one power supply component 221 and the battery cells 223 of the other power supply component 221, so that the battery cells 223 of the two power supply components 221 are connected in series. It should be noted that the electrical connection lines provided on the electrical connection plates 222 enable the battery cells 223 between the two power supply components 221 to be connected to each other in a positive and negative manner, thereby realizing the series connection of the battery cells 223. For example, the circuits on the electrical connection plates 222 are connected in an alternate row manner, so that the first row and the third row, the second row and the fourth row on the two power supply components 221 are connected, and a connecting line is led out to connect to the BMS system 210 to realize power supply. In this embodiment, the electrical connection plate 222 is an electrical contact plate. Figure 4 The electrodes of the two power supply components 221 are connected together on the same side, so that the two power supply components 221 are connected in series. The above structure can avoid local overheating caused by the electrodes of the electrodes of the electrodes of the electrodes of the electrodes of the electrodes of the electrodes of the electrodes of the electrodes of the electrodes of the electrodes of the electrodes of the electrodes of the electrodes of the body of the device 100 being arranged in the same way, and facilitates the rational layout of the power supply circuit. Of course, the electrical connection plate 222 can also use other connection methods in the prior art to realize the series conduction of the electrodes of the electrodes of the electrodes of the electrodes of the electrodes of the electrodes of the devices of the device 100, all of which are within the scope of the present invention.

[0032] Furthermore, the outdoor energy storage device of this embodiment also includes a temperature detection component 700. The temperature detection component 700 is used to monitor the temperature of the energy storage component 200. It includes multiple temperature detection components disposed between two adjacent power components 221. In this embodiment, the temperature detection component is a temperature sensor, which can be configured as a contact type. Its detection end is disposed between the two power components 221 and in contact with the surface of the battery cell 223 (not shown in the figure). Alternatively, it can be configured to contact the electrical connection plate 222. By monitoring the temperature between the power components 221 or the temperature of the electrical connection plate 222, the temperature of each power component 221 in the energy storage component 200 can be obtained. This allows for timely feedback to the BMS system 210 when the internal temperature is abnormal. The BMS system 210 then reduces the output power or stops the power output based on the feedback information to ensure the stability of the internal environment of the device. Of course, the temperature sensor can also be configured as a non-contact type, such as an infrared sensor, which can also achieve the temperature monitoring effect.

[0033] In another embodiment, the device body 100 includes a first side and a second side disposed opposite to each other in a first direction, and each electrical connection plate 222 is disposed on the first side or the second side, so as to Figure 3 Taking the embodiment shown as an example, the first direction is the vertical direction, and the first side and the second side are the upper side and the lower side, respectively. By arranging the electrical connection board 222 on the vertical side, the internal space of the device can be effectively utilized, making the overall circuit connection more compact and orderly. At the same time, each power supply component 221 is arranged in the device body 100 along a second direction perpendicular to the first direction. Figure 3 The implementation is in the forward and backward direction.

[0034] The device body 100 also includes a buffer assembly 800, which comprises multiple buffer pads 810. The energy storage assembly 200 has multiple opposing walls spaced apart from the device body 100. These opposing walls are formed on the outer surfaces of the arranged battery cells 223. The device body 100 has sidewalls spaced parallel to the multiple opposing walls, including a first sidewall. The first sidewall is described as follows: Figure 1 The charging port 400, each of the discharge ports 500, and the fast charging port 620 are all located on the front wall of the device body 100, forming the power output terminal of the device body 100 on that side. A buffer pad 810 is disposed in the gap between each opposing wall and the other side walls besides the first side wall. Figure 3 and Figure 4In the embodiment shown, buffer pads 810 are provided on the rear, left, right, upper and lower sides of the energy storage component 200. The buffer pads 810 provide a buffering effect for the energy storage component 200 (mainly the power module 220) inside the device body 100 to avoid collision and impact. However, no buffer pads 810 are provided on the first side wall to avoid local overheating near the interface during power output, which could ignite the buffer pads 810. This provides sufficient buffering force for the energy storage component 200 while ensuring internal safety.

[0035] In addition, the BMS system 210 is implemented within the device body 100 by a control motherboard. The outdoor energy storage device also includes a display 900, which has a display screen exposed on the outside of the device body 100. It is connected to the BMS system 210 and provides feedback on relevant information of the energy storage component 200 so that users can view the device status and input corresponding operations into the BMS system 210.

[0036] Finally, it should be noted that the above description is merely the preferred embodiment of this utility model and is not intended to limit the utility model in any way. Any person skilled in the art can make many possible changes and simple substitutions to the technical solution of this utility model using the disclosed methods and technical content without departing from the scope of the technical solution of this utility model, and these all fall within the protection scope of the technical solution of this utility model.
