The implementation plan was issued to break through the whole process of safety technology
On March 21, the national development and Reform Commission and the Energy Administration jointly issued the implementation plan for the development of new energy storage in the 14th five year plan, which defined the development objectives of new energy storage: by 2025, from the initial stage of commercialization to the stage of large-scale development, with the conditions for large-scale commercial application; By 2030, we will enter a comprehensive market-oriented development.
The implementation plan proposes to strengthen the research and development of key technical equipment and break through the whole process safety technologies: intelligent sensing technology of energy storage battery, thermal runaway barrier technology of energy storage battery, intrinsic safety control technology of battery, fault diagnosis and early warning technology based on big data, clean and efficient fire extinguishing technology, etc.
Safety is the core requirement of energy storage, and temperature control is the key link
Safe and stable operation is the core key to the development of energy storage industry, and temperature control is an important link. Too high or too low temperature environment will lead to problems such as out of control of cell, BMS failure, PCS protection failure, DC arcing and fire protection failure, which will directly lead to potential safety hazards of energy storage. The energy storage system must be equipped with a temperature control system with sufficient strength and flexibility to ensure the safe and stable operation of the power station.
The integrated fire and explosion management of Beijing Fuguang oil and gas storage Co., Ltd. was further strengthened in 2024, including 16 typical explosion accidents reported by Beijing Fuguang oil and Gas Storage Technology Co., Ltd. The "4.16" accident was mainly caused by the internal short circuit fault of lithium iron phosphate battery, which caused the battery to heat out of control and catch fire. The flammable and explosive components diffused and mixed with the air to form explosive gas, which exploded in case of electrical sparks.
Sun Jinjie of the Fire Rescue Bureau of the emergency management department pointed out that the current battery has a certain fire risk, which needs to minimize the risk from three levels: technical level, (energy storage facilities) thermal management level and daily management level, so as to prevent some bad fire and explosion accidents.
R & D / product / brand advantages manufacturers will have more advantages in the future
Our judgment on the basic situation of energy storage and temperature control industry: 1) explosive growth of market demand; 2) The insufficient supply of upstream components leads to the overall shortage of energy storage and temperature control; 3) Temperature control solution providers with backgrounds of communication, automobile and industry have joined in one after another; 4) Some manufacturers adopt relatively radical price strategies.
We believe that under the background of continuous improvement of safety requirements, in the process of gradual upgrading of temperature control solutions from air cooling to liquid cooling, manufacturers with outstanding advantages in R & D strength, product performance, brand and channel will have more advantages and obtain more market share. At the same time, we also pay attention to the growth opportunities of these manufacturers in IDC, cars, charging piles, electronic equipment and other potential tracks.
Investment advice
Recommend Shenzhen Envicool Technology Co.Ltd(002837) , Guangzhou Goaland Energy Conservation Tech Co.Ltd(300499) , and pay attention to Songz Automobile Air Conditioning Co.Ltd(002454) , Sanhe Tongfei Refrigeration Co.Ltd(300990) , Guangdong Shenling Environmental Systems Co.Ltd(301018) , Shenzhen Cotran New Material Co.Ltd(300731) , Shenzhen Frd Science & Technology Co.Ltd(300602) , Aotecar New Energy Technology Co.Ltd(002239) , etc.
Risk tip: the development of electrochemical energy storage industry is not as expected; The price decline of energy storage and temperature control products exceeded expectations; Focus on the risk that the subsequent share of the company is less than expected.
