Speaking of energy storage products, what comes to mind may be large-scale electric power storage, industrial and commercial energy storage equipment, but in fact, with the upgrading of science and technology and user consumption as well as the refinement of energy utilization around the world, more and more energy storage products show home use, portable.

As a lithium, energy storage with 18 years of experience in R & D and production of Shielden technology company's authors, against the company's production of a series of home energy storage products and portable energy storage products as well as their characteristics, to talk to you about this topic.

I. Household Energy Storage Products

Household energy storage products are used for home user scenarios of the energy storage system, usually combined with household photovoltaic systems installed to provide electricity for home users.

The installed size of this type of product is usually above 10kWh level, and usually above the megawatt-hour level of power generation side/grid side/industrial and commercial energy storage, compared to a much smaller single machine size.

Saving electricity costs is an important motivation for users to allocate storage. Household energy storage products generally in the daytime power generation, but the peak of home users in the night, power generation and power time mismatch, configuration of energy storage can help users will be more electricity during the day to store for night use; on the other hand, the user at different times of the day electricity tariffs are different, the existence of peaks and valleys, the storage system can be used in the valley time through the grid or self-use of photovoltaic panels to charge, the peak hours of discharge for the load to use, thus avoiding the need to use the energy storage system. The energy storage system can be charged by the grid or self-used photovoltaic panels during the low hours and discharged for use by the loads during the peak hours, thus avoiding the need to use electricity from the grid during the peak hours and effectively saving electricity costs.

A home energy storage product system usually consists of a battery pack, a battery management system (BMS), an energy storage converter (PCS), and an energy management system (EMS), with the energy storage battery and converter being the higher-value core components.

In terms of product form, it is equivalent to an extension of high-capacity portable energy storage. Expansion is achieved by stacking products and modules; the positioning is also more flexible, which can meet the emergency demand of a few degrees of electricity, and can also be extended to whole-house backup power. Taking into account the attributes of outdoor use, such as outdoor activities, outdoor gardens, RVs and other scenarios, it can be realized by a mobile design with wheels or by moving a battery module.

The home-based PV energy storage system consists of a PV grid-connected and off-grid system, an energy storage inverter, a battery, and a load. For a villa family, a 5kW PV energy storage system can fully satisfy the daily power consumption.

During the daytime when there is light, the PV panels on the roof can provide all the electricity needs for the villa family, as well as powering the new energy vehicle. When all of these basic applications are met, the remaining power goes into the storage battery to prepare for nighttime energy needs and cloudy weather, ensuring the effective operation of the complete home-based energy storage system.

In the event of an unexpected power outage, the home energy storage system, maintains continuity of power supply with minimal response time. Home energy storage system makes solar panel power generation more reliable, avoiding the shortcomings of not being able to generate electricity on cloudy and rainy days, which is undoubtedly an excellent choice for villa backup power.

Affected by the world energy crisis, home storage system is becoming more and more common, accepted and loved by everyone, and is the forerunner in implementing sustainable development.

Especially in Europe and the United States, this home energy storage products are very popular, in recent years, there are more and more families in China to respond to the national "green energy" call, choose this form of energy storage.

II, portable energy storage products

1, portable energy storage products application scenarios

Self-driving tours, outdoor camping has become a popular way to go out. In addition to traditional camping equipment, rice cookers, kettles, coffee makers, projectors, drones, photographic equipment, mobile air conditioning, insulation boxes and other small appliances have gradually become "exquisite camping" standard equipment.

Camping tropical drive peripheral industry heating, portable energy storage products is one of the new categories of growth is breaking out.

This type of product is mainly for outdoor lighting, emergency lighting, mobile stalls, mountain and wild woodland operations and other activities, for cell phone charging, LED lighting, aerial photography, AC fans, DC fans and other AC and DC equipment power supply, control circuits, inverter circuits and lithium batteries are integrated, easy to carry, simple to use.

2, the advantages of portable energy storage products

Portable energy storage products are prioritized to include: more power; more rich interfaces; easy to carry; support for simultaneous charging of multiple digital devices; support for a variety of charging methods; charging time is short and long endurance, and so on.

3、Types of portable energy storage products

Portable power stations can be divided into two categories according to the amount of single-unit power: one is the amount of power for 0.5-3kwh of small, lightweight equipment; the other is the amount of power in the 5kwh to 30kwh of the equipment, the main alternative to the previous fuel generator market.

In addition to charging in advance, portable energy storage can also support the use of solar panels, solar panels single piece of output power between 60w to 400w, so that when the battery runs out of power, the use of photovoltaic in the outdoor charging of energy storage, the composition of a small solar power system, to achieve sustained off-grid power generation, to extend the power supply range time.

At present, we have developed 3.6kwh portable energy storage power station for home use and 32kwh industrial energy storage power station, which are suitable for home use and industrial scenarios such as hotels, banks, hospitals, etc., and both of them have been fully launched to the market and have been sold to a number of countries in the world.
