Does a lithium-ion battery energy storage system have a large temperature difference?
In actual operation, the core temperature and the surface temperature of the lithium-ion battery energy storage system may have a large temperature difference. However, only the surface temperature of the lithium-ion battery energy storage system can be easily measured.
How to secure the thermal safety of energy storage system?
To secure the thermal safety of the energy storage system, a multi-step ahead thermal warning network for the energy storage system based on the core temperature detection is developed in this paper. The thermal warning network utilizes the measurement difference and an integrated long and short-term memory network to process the input time series.
Why is battery energy storage a safety problem?
Due to the “short board effect”, the available capacity of BESS will decrease, resulting in failure . Therefore, with the emergence of the scale effect of battery energy storage, the safety problem has become a new risk challenge faced by the development of energy storage. We should pay attention to the safety risk management in time.
