According to PV Magazine reported on October 30, in the Lauterbach area of the central German state of Hesse, a 30kWh household battery energy storage system exploded. The occurrence of this accident will once again draw the attention of industry users to the potential safety problems of energy storage systems.
According to incomplete statistics, in the second half of September, eight energy storage system fires and explosions occurred in the world, including the battery energy storage unit fire in the Valley Center energy storage project in the United States, the Bouldercombe battery energy storage project fire in Australia, and the explosion of photovoltaic energy storage devices in French chicken farms. After the summary of the accident, it was found that among the 8 energy storage fire accidents, energy storage system fire and explosion accidents occurred in household energy storage projects accounted for more than half (5/8). At the same time, large-scale energy storage power stations, and industrial and commercial energy storage systems are also involved.
Accident Analysis
1. The large number of energy storage systems used in a household means a greater probability and frequency of exposure to fire risk;
2. The small scale of the two-household energy storage system lacks corresponding standards and supervision in manufacturing, installation, and maintenance, leading to security risks;
3. Compared with large-scale energy storage systems, household systems lack professional operation and maintenance teams, which further increases security risks;
4. Lack of special operation and maintenance instruments and maintenance equipment, found early warning problems cannot be handled in time;
5. Electrochemical energy storage is inherently unstable, and thermal runaway inside the battery and the system is difficult to completely avoid.
