Description

Technical Field

[0001] This utility model relates to the field of energy storage device technology, specifically to an intelligent integrated lithium battery energy storage device. Background Technology

[0002] Lithium battery energy storage devices are devices that use lithium-ion batteries to store electrical energy. They are mainly used to store and release electrical energy to balance power supply and demand, improve grid stability, or power off-grid devices. Currently, in 48V low-voltage energy storage applications, multiple products such as inverters and energy storage batteries often exist independently. This results in a low level of integration of the energy storage system in actual applications, making it unsuitable for small-scale applications, such as home appliances.

[0003] In response to the problems exposed during the use of current lithium battery energy storage devices, it is necessary to improve and optimize the structure of lithium battery energy storage devices. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] like Figure 1-5 As shown, the intelligent all-in-one lithium battery energy storage device disclosed in this utility model includes a device body 1. The device body 1 has a storage chamber for storing energy storage batteries and a control chamber for storing control components. Several sets of power modules 8 are embedded in the storage chamber. An inverter module 11 is located inside the control chamber and is fixedly connected to the inner wall of the device body 1 by bolts. A partition plate is also provided in the area where the storage chamber and the control chamber are in contact. A control module 10 is embedded in the partition plate. The inverter module 11 is electrically connected to the control module 10, and the control module 10 is electrically connected to the power modules 8.

[0024] A number of cooling fans 7 are embedded on one side of the inverter module 11 on the side surface of the device body 1. A number of heat dissipation holes are evenly opened on the side wall of the inverter module 11 away from the cooling fans 7, so that a heat dissipation air duct for heat exchange of the inverter module 11 is formed inside the control room. This technical solution has a high degree of integration, integrating multiple functional modules such as inverter, battery, and charging management into one unit. Compared with the traditional split energy storage system, it reduces the equipment footprint and installation complexity, and saves installation space and cost.

[0025] The technical solution is plug-and-play; users only need to connect it to their home power system and perform simple setup and debugging to start using it. No complicated wiring or professional installers are required, which greatly reduces the barrier to entry for users.

[0026] In practical implementation, this technical solution can store excess electricity generated by the solar power system, as well as low-cost electricity during off-peak hours. The storage capacity is generally in the thousands of kilowatt-hours, and different capacities can meet the electricity needs of different family sizes.

[0027] Specifically, the storage compartment is also equipped with several rows of stabilizing frames 9. The ends of the stabilizing frames 9 are fixedly connected to the inner wall of the device body 1, and the side walls of the stabilizing frames 9 abut against the power module 8 and limit and fix the power module 8. A first sealing plate 2 is fitted into one side of the power module 8 on the side wall of the device body 1. In this embodiment, the stabilizing frames 9 improve the shock resistance of the power module 8, and the opening and closing structure of the first sealing plate 2 facilitates the replacement of the power module 8 in the device.

[0028] The control module is responsible for managing and coordinating the work of each component, realizing functions such as charge and discharge control, power regulation, fault diagnosis and protection, and ensuring the stable and efficient operation of the entire system; the BMS can monitor the battery's voltage, current, temperature and other parameters in real time, and intelligently adjust the charging and discharging process based on these parameters; for example, when the battery is close to being fully charged, it automatically reduces the charging current to avoid overcharging; it can effectively protect the battery and extend its life.

[0029] The BMS has fault diagnosis capabilities, which can promptly detect potential internal faults in the battery, such as short circuits and capacity degradation, and issue warning signals to the user. This helps the user take timely measures to prevent the fault from worsening and ensure the safe operation of the system.

[0030] Specifically, a second sealing plate 3 is also fitted into the side wall of the device body 1 on one side of the control room, and a control display screen 4 is also fitted into the side wall of the second sealing plate 3. In this embodiment, it is more convenient for users to operate the equipment.

[0031] Specifically, one end of the control room is also fitted with a PV input terminal 5 and an AC terminal 6 on the side wall of the device body 1. The PV input terminal 5 can be electrically connected to the solar power supply interface of the solar photovoltaic system to supply power to the inverter module 11. The AC terminal 6 is connected to the mains power to supply power to the inverter module 11. In the implementation of this embodiment, when the mains power fails, the integrated machine automatically switches to the independent power supply mode to provide emergency power support for key appliances in the home, such as lighting fixtures, air conditioners, and refrigerators, to ensure the basic living needs of the family.

[0032] Specifically, handles 12 are also fitted onto both sides of the device body 1, which facilitates quick handling and transfer of the device in this embodiment.

[0033] Specifically, the control module 10 is also connected to a WIFI module. In this embodiment, during actual application, users can log in via a home WIFI mobile APP or computer terminal platform, allowing users to monitor energy information anytime and anywhere using PC and mobile platforms, regardless of their location.

[0034] The working principle and usage process of this utility model: In this utility model, the inverter built into the all-in-one machine converts the DC power stored in the battery into AC power to adapt to most electrical appliances in the home that require AC power to operate.

[0035] In this technical solution, when external power supply is unavailable, the energy storage system supplies power to the household. The power module 8 converts the current through the inverter module 11 and supplies power to the household electrical equipment through the AC terminal 6.

[0036] When the energy storage device needs to be powered, it is connected to the mains power through AC terminal 6. The inverter module 11 converts the current and supplies power to the power module 8 to replenish the power. The cooling fan 7 in the device pressurizes the airflow, so that when the airflow flows to the inverter module 11, the air exchanges heat with the inverter module 11 and the control module 10 to dissipate heat inside the device.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to further limit the present utility model. All equivalent changes made based on the description and drawings of the present utility model are within the protection scope of the present utility model.
