Household energy storage equipment is to store electrical energy and use it when needed - also known as electric energy storage products or "battery energy storage system" (BESS), hereinafter referred to as HES. The core component of HES is a rechargeable battery, usually a lithium-ion battery or a lead-acid battery. The other components are inverters, a control system that can intelligently control charging and discharging.

Portable energy storage power supply, referred to as "outdoor power supply", is a small energy storage device with a built-in lithium-ion battery that replaces traditional small fuel generators. It has the characteristics of large capacity, high power, safety and portability, and can provide stable AC/DC Power supply system.

With the development of the economy and the progress of the society, the peak-to-valley difference in the load curve is getting bigger and bigger. The industrial and commercial energy storage system can effectively reduce the impact of the peak power shortage on the development of the local economy, industry and commerce, and promote the harmonious development of society and economy.

"The "solar-storage-charge" integrated charging station is a high-tech green charging mode that realizes photovoltaic, energy storage, and intelligent charging to coordinate and support each other through "support charging piles with photovoltaic facilities". The smart micro-grid system intelligently interacts with the public grid according to needs. Using the battery energy storage system to absorb valley electricity and support fast-charging loads during peak periods not only realizes "peak-shaving and valley-filling", but also saves the cost of power distribution capacity expansion and increases new energy.
