[0022] 1. Battery casing; 2. Interface board; Detailed Implementation

[0023] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] Combined with appendix Figure 1-3An energy storage device includes a battery housing 1 and an interface plate 2 installed at the end of the battery housing 1. The battery housing 1 is an upward-opening and hollow shell structure. The internal space of the battery housing is used to install a battery pack, which is used to store electrical energy, thereby supplying power to the outside when the device is connected to the energy storage device.

[0026] Interface board 2 is fixedly installed at the opening on the top of battery housing 1. Interface board 2 is equipped with integrated circuit and several interfaces of different specifications, which can be connected to power lines with different requirements. Interface board 2 is also equipped with integrated circuit, which integrates charging management circuit, inverter and transformer circuit, control protection circuit and power-on circuit.

[0027] Charging management circuit module: This circuit system can accurately regulate and manage the power input process of the external power source to the battery pack. Through the preset charging and discharging control algorithm, it can effectively prevent abnormal situations such as overcharging or excessive current from occurring in the battery pack, thereby protecting the internal cell structure of the battery and significantly extending the overall service life and safety of the battery pack.

[0028] Inverter and transformer circuit system: This circuit unit plays a crucial role in converting AC and DC power, while also possessing the capability to transform DC voltage levels. The inverter circuit converts DC power to AC power, while the transformer circuit converts DC power to different voltage levels. This dual-conversion design enables energy storage devices to provide multiple power supply modes, including 220V AC, 12V DC, and 5V DC, greatly expanding the application range and usage scenarios of energy storage devices.

[0029] Intelligent Control and Protection Module: This module uses high-precision sensors to continuously monitor the system's operating status, collecting key parameters such as voltage, current, and temperature in real time, and is equipped with multiple protection mechanisms. When abnormal conditions such as overcharging, over-discharging, short circuits, or excessively high temperatures are detected, corresponding protection measures will be triggered immediately to cut off the faulty circuit, effectively preventing potential safety accidents and ensuring the safety of both users and equipment.

[0030] Power switch control circuit: This circuit not only integrates conventional power switch functions to enable normal start-up and shutdown of the energy storage device, but also features a specially designed manual emergency power-off device. In emergencies, users can quickly operate this device to immediately cut off the power supply. This design ensures both convenience for daily use and provides necessary safety guarantees.

[0031] The interfaces on interface board 2 generally include several 12V DC interfaces, several 5V USB interfaces, several 5V Type-C interfaces, and also 220V AC interfaces with three-prong and two-prong plugs.

[0032] An LED bead is fixedly installed on the interface board 2. The LED bead is directly powered by the battery pack through the integrated circuit. A light switch is also provided between the LED bead and the integrated circuit. The LED bead enables the energy storage bank to act as a light source, thus enabling the energy storage bank to bring convenience to users in dark environments.

[0033] A heat-conducting plate that fits into the battery pack can be installed inside the battery housing 1. The heat-conducting plate is recessed into the battery housing 1. When the battery pack is installed inside the battery housing 1, it fits into the heat-conducting plate. There is a gap between the heat-conducting plate and the battery housing 1. A fan is installed in the gap between the heat-conducting plate and the battery housing 1. The fan plays a heat dissipation role. The fan is also powered by the battery pack through an integrated circuit. A fan switch is installed between the fan and the integrated circuit. The fan can be manually turned on, thereby cooling the battery pack inside the energy storage pack when the energy storage pack is used for a long time and preventing accidents.

[0034] The interface board 2 can also be equipped with a display screen, which can display the remaining power of the battery pack and indicate the charging status, so that users can accurately know the remaining power of the energy storage bank.

[0035] The interface board 2 is also equipped with an AC switch and a DC switch. The AC switch is used to control whether the AC interface is powered on or not, and the DC switch is used to control whether the DC interface is powered on or not. The AC and DC switches can further improve the safety factor. By turning on the AC switch when the AC interface is needed and turning on the DC interface when the DC interface is needed, the user can be further protected to prevent accidents from occurring when all interfaces are powered on during use.

[0036] The interface board 2 is also equipped with a charging interface, preferably an AC charging structure, which can more conveniently charge the energy storage pack and save charging time.

[0037] The interface board 2 and the battery housing 1 are detachably connected. By removing the interface board 2 from the battery housing 1, the battery pack located inside the battery housing 1 can be taken out. The battery pack can be replaced and charged, thereby improving efficiency and convenience. The detachable connection between the interface board 2 and the battery housing 1 is preferably a snap-fit ​​connection, or the interface board 2 can also be rotated and installed on the battery housing 1 as a cover.

[0038] A handle can also be fixed to either the interface board 2 or the battery casing 1 for easy carrying of the energy storage bank.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
