Behind the explosion of the Beijing lithium-ion battery storage power station, what do we think? It is not easy to save, safety first. Beijing storage energy station explosion accident sounds the warning system for energy storage system security issues. What is the overall safety situation in the energy storage market? What is important causes of safety incidents in the storage power station? This article, Xiaobian is talking to everyone.

Beijing Lithium-ion battery storage power station fire explosion incident explains the afternoon of April 16, 2021, the fire and explosion of Beijing South Fourth Ring, a lithium-ion battery storage power station, causing 2 firefighters to sacrifice, 1 firefighter injured (injury Stable stable), 1 employee in the power station. The accident is the most serious accident in China's energy storage power station in recent years. Accident review: At 12:17 on April 16, Beijing 119 Command Center received a police station that fired the fire station of No.

14, Western Himan, Yongwai, Fengtai District, dispatched 15 fire station 47 235 fire trucks refer to the war. At 14:15, during the disposal of the South District of the power station, the North District of the power station broke out without signs, causing 2 firefighters to sacrifice, 1 firefighter was injured (stable and stable), in the power station 1 employee failed. After preliminary investigation, the fire site is Beijing Guoxuan Fuweiz Light Reserve Technology Co.

, Ltd. Before the incident, the power station is carrying out construction and debugging. Why does the energy storage power station exploded a fire accident? In this regard, the industry related experts said that the energy storage power station does have the likelihood of explosion.

The storage capacity is a bulk energy storage battery. At present, the energy storage battery is multi-lithium-ion battery, its price / performance ratio is more advantageous than other batteries. However, lithium-ion batteries can easily occur internally short-circuition, resulting in spontaneous combustion.

Simply, the lithium-ion battery is an electrical product, and there will be a short circuit. There is a lot of flammable products in the lithium-ion battery, and the fire is very violent, and combustible gas. The energy storage container is a sealed box.

A large number of lithium-ion batteries are stored in this box. After the battery spontaneous combustion, the flammable gas in the box may explode throughout the box, and they have the same Mars with the empty oil tank. The industry believes that it is a system that causes the final reservoir project to cause accidents to support peripheral systems with the battery, such as lithium-ion battery management system, energy management system, container design, some specific scenes to deal with strategy, insulation materials Select layout, fire extinguishing, etc.

, so security test before project delivery is important. Beijing storage energy station exploded, what is our thinking? "Safety" is the topic that is not open to the development. The security problem of storage energy stations is the common challenge in the global energy storage industry, and the fire-saving power station fire incident has occurred many times.

It is recommended that the energy storage power station does online monitoring, prevent accidents, and reduce the tragedy of Fengtai storage station. At present, the important reason for the storage safety accident is that lithium is flexible, accompanied by heat loss, but the accident point is often not a battery, we see more causes due to electrical accidents. Safety is a complex system that cannot be simply broken down to battery selection, and the supporting system is equally important.

Although lithium battery has a risk of flammable, thermal out-of control, but through strictly effective control, from a safety perspective, admission threshold is improved, and through sufficient safety test and authority certification can guarantee the safety of lithium-ion battery energy storage system. The energy storage security new realm -BMS lithium-ion battery management system BMS battery management system is one of the core components of the energy storage system. Its functional security is an important part of equipment security.

It is important to consider the control system related to electronic circuitry. Risks caused by controlled equipment and their related systems in failure or failure. BMS as a core component of the battery system, realizing battery condition monitoring, battery condition analysis, battery safety protection, energy control management, battery information management, and do a good warning in advance.

It can acquire, process, store important information during battery pack operation in real time, exchange information with external devices such as controller, solve key issues such as security, availability, ease of use, service life in lithium-ion battery systems. Lithium-ion battery BMS management system is not as optional as some battery manufacturers, but must be used throughout the battery pack application. The lithium-ion battery management system has studied at home and abroad and began to be applied in many fields.

It has been able to meet some markets, and the application of lithium-ion battery management system has put forward higher requirements to ensure safety, lithium ions. Battery management system is an important task. Summary: Safety issues of storage power stations are not unprofable.

With the improvement of domestic energy storage power stations, we must improve the safety standard system, including mandatory national standards, and enhance the safety level of the entire industry through mandatory safety certification. Strengthen the safety protection of the energy storage system, prevent or mitigate the impact of external stimulus on the body's body, and actively inhibit the enlargement of hidden dangers.
