On April 18, SPECO unveiled a new, first-of-its kind mobile (vehicular) energy storage system for China. The device was unveiled and put into use at the 70th anniversary of the People’s Liberation Army Navy celebrations in Qingdao. The system can provide a variety of services, such as load shifting, emergency power supply, backup power, smart charging, mobile rescue services, and more. The unit can be used in disaster situations such as earthquakes and avalanches, provide power for large public events, or provide backup power to data centers, hospitals, airports, and other facilities. It can also provide islands, mountainous regions, and commercial areas with load shifting capabilities, be used for electric vehicle charging in cities, or even provide power during infrastructure repairs.
On April 1, 2019, a China Telecom energy storage system located at a monitoring station in Jianggan District, Hangzhou became the receiver of China’s first sodium nickel battery. The battery system is provided by Zhejiang AM Power, a joint venture between Chilwee Group and GE.
Sodium Nickel batteries are a high temperature sodium battery. Advantages are its relative safety, environmental friendliness, long life cycle, and cheap manufacturing cost. The batteries pose no risk of catching fire or exploding, can operate in temperatures as low as -40 degrees Celsius and as high as 65 degrees Celsius, and have life cycles typically two to five times that of Li-ion batteries.
KSTAR and CATL have contributed 102 million RMB and 98 million RMB, respectively, to form a joint venture. CATL will hold 51% stake in the venture, while KSTAR will hold the remaining 49%. The venture will focus on energy storage system PCS, battery packs (including UPS-integrated Li-ion battery packs, residential energy storage battery packs, and packs for small-to-medium Li-ion batteries of nonstandard size), as well charging stations and “solar+storage+charging” integrated products.
KSTAR was founded in 1993. The company researches, manufactures, and provides integrated solutions in a variety of product areas, including key data center infrastructure, solar PV generation systems, energy storage systems, and electric vehicle charging.
