Description

Technical Field

[0001] The utility model relates to a shared rental light storage and charging system and an integrated device. Background Art

[0002] The emergence of overseas household energy storage system sharing and leasing models is influenced by many factors, including energy market liberalization, renewable energy policy support, energy democratization advocacy, technological progress, and environmental protection needs. This model helps promote the use of clean energy, improve energy efficiency, promote energy democratization, and achieve sustainable development goals.

[0003] In response to the differentiated demands of the overseas energy storage market, this type of household shared leasing energy storage system device has emerged, which is provided to users free of charge or at a low price by third-party shared leasing companies to reduce users' initial investment costs. The solar storage and charging system is installed and deployed in the user's residential area, and the user rents the energy storage system on demand to meet household electricity needs, electric vehicle charging needs or participate in electricity market transactions.

[0004] At present, most of the household energy storage system application scenarios use split energy storage systems and charging systems, which are composed of inverters, battery packs, and charging piles from different manufacturers in a split installation and matching manner to form a solar energy storage and charging system. This method has the following disadvantages:

[0005] 1. The system is composed of split equipment. Users need to make appointments with different manufacturers for installation according to their needs. However, it is difficult to unify the arrival and installation time of different manufacturers, so the system installation time is too long and multiple installations are required, which leads to high installation costs.

[0006] 2. Multiple debugging and testing affect user experience: Since the system is composed of split devices, the devices may be products of the same manufacturer or different manufacturers. After a single device is installed, it needs to be debugged separately, and each installed device needs to be systematically debugged, which affects the debugging and testing efficiency and seriously affects the user experience.

[0007] 3. This kind of split installation of multiple devices requires multiple installations in stages and steps. Therefore, the power lines and communication lines between the energy storage battery pack, inverter, and charging pile are connected to each split device through cable troughs, which may pose a safety hazard during later use and operation and maintenance.

[0008] 4. Exposed wiring is not aesthetically pleasing: This type of multi-device is installed in a split manner, and usually the wire ducts are exposed for matching wiring, resulting in an overall uncoordinated and unsightly effect. If the colors of different manufacturers are inconsistent, the effect will be even worse.

[0009] 5. Using multiple apps affects user experience: With this multi-device split group system, the inverter, battery pack, and charging pile all have independent apps for viewing data. This requires customers to install multiple apps for different device types to view the device operation and energy usage, which affects the user experience.

[0010] 6. Inconvenient operation and maintenance: Due to the operation and installation of this multi-device group system, the adaptation between each device, firmware upgrades, troubleshooting, and remote operation and maintenance require contacting different manufacturers, which brings huge challenges to the overall system operation and maintenance.

[0011] Therefore, for application scenarios such as shared rental photovoltaic storage and charging systems, the use of this split multi-device photovoltaic storage and charging system has different degrees of pain points in system installation, system debugging, operation and maintenance, and user experience.
