Market:
In 2019, global grid-connected energy storage will reach 4.3 GW. China-US installed capacity will exceed half of the world.
Relevant organizations analyzed and predicted that 4.3 GW of grid-connected energy storage will be deployed globally in 2019; by 2025, the installed capacity of global grid-connected energy storage will reach 10.6 GW per year.
 
In 2018, the four major markets of South Korea, the United Kingdom, China and the United States accounted for more than 60% of the total installed capacity in the world. Earlier this year, a report also showed that China and the United States are the fastest growing energy storage markets in the world. It is expected that by 2024, the two countries will account for more than half of the total installed energy storage capacity in the world. This year, the United States will become the largest energy storage market, and the demand for solar energy + energy storage equipment and peak capacity will drive the purchase of energy storage by major US commercial organizations.

Project:
Shanghai Jiading's first "light storage and charging" integrated charging station put into operation
On May 29th, the first smart charging grid demonstration service station in Jiading District, Shanghai, which integrates photovoltaic, energy storage and charging, was officially put into operation.
It is understood that the “Shanghai Changjiang Cairi Charging Station”, which was built by the Yangtze River Wisdom Investment, is located in the Shanghai Changjiang Cairi Technology Energy Co., Ltd., Jiasong North Road, Jiading District, Shanghai. It covers an area of ​​660 square meters and has a total of 10 charging piles. There are 8 60kW and 2 kW AC charging posts. The station has built-in storage capacity of 1088kWH energy storage power station and 10kW carport photovoltaic, which can meet the charging requirements of 100 electric logistics vehicles in Jiading District of Shanghai every day. After the charging station enters the normalized and effective operation, the cost of freight in Shanghai Jiading City can be reduced by up to 60%.
 
Jiangsu Province's first "light storage + one-stop" service charging station
The first “light storage + one-stop” service charging station in Jiangsu Province was settled at the junction of Chunchao Road and Youyi South Road in Xishan District, Wuxi.
It is understood that the optical charging and charging station is equipped with a 16.5 kW rooftop distributed photovoltaic power station, together with a nearby 600 kWh energy storage station to provide green and clean energy for the operation of the charging station. The intelligent control system in the station monitors the energy input on the grid side and the distributed photovoltaic power generation side and the power value of the external energy output of the charging pile in real time. The energy storage system adjusts the charging and discharging power in real time, and optimizes various energy forms such as electric energy, solar energy and chemical energy. Configuration to maximize the efficiency of integrated energy use.
According to reports, the charging station has a charging power of 80 kW, which saves about 20% of the time per charge.
