In recent years, the frequent occurrence of battery energy storage system fires and even explosions has become a major concern in the industry. Therefore, safety has once again become a key factor in choosing a battery energy storage system. Given that there are various battery products and energy storage technologies available in the market, it is believed that users can make the safest choice through careful consideration and advice.
Choose the appropriate energy storage technologies battery
In terms of safety, it is necessary to distinguish between primary safety (what measures can be taken to prevent accidents) and secondary safety (how to better control and manage dangers after accidents occur). Basic safety is directly related to the battery itself.
There are different types of batteries available nowadays, but each has its own advantages and disadvantages. However, the most important thing is to consider whether the battery complies with international standards. Users need to choose energy storage products based on this standard, which specifically targets the safety of batteries.
Ensure the safe integration of energy storage technology battery modules, racks, and containers
For modules and racks: ensure that the battery complies with international standards. Choosing a battery that has passed the standard certification means that it has been tested and simulated for thermal runaway events to check whether the fire will not spread.
Invest in the right energy storage technology battery management system and energy management software
Using a safe and standard-compliant battery is the mandatory first step to ensure the highest safety level; however, how to use the battery is also crucial. This is why the battery management system should ensure that the battery operation will not exceed its limits. To provide this safety function, the battery management system must be certified by the functional safety standard for electrical/electronic/programmable electronic safety-related systems.
The energy storage technologies battery management system generates a large amount of data, which is read by the energy management software, saved locally, and regularly backed up to a secure cloud computing system. All of this data can be used for analysis purposes to detect potential improper battery behavior or deviations early and optimize system operation.
Ensure that the energy storage technologies battery has a circuit breaker
To ensure safety, the battery energy storage system must be equipped with all necessary electrical disconnect devices, such as load circuit breakers, to ensure safe isolation for maintenance operations.
Safe transport of energy storage technologies batteries
Lithium-ion batteries have been identified as class 9 dangerous goods for transportation. Energy storage technologies battery systems must be transported by air, sea, railway, or road in accordance with international standards.
