Therefore, in the design of the energy storage system thermal management system, if only the surface temperature is used to determine the safety level of the energy storage system, the energy storage system may be in a dangerous state.
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.
As shown in Eq. (25). In this paper, a novel multi-step ahead thermal warning network is proposed for the energy storage system as the core temperature overrun warning. Various methods are compared to prove the accuracy advantage of the proposed model.
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.
The cause and influence of the rise of core temperature. Due to the heat generation and heat dissipation inside the lithium battery energy storage system, there may be a large temperature difference between the surface temperature and the core temperature of the lithium battery energy storage system 6.
This is because a lot of heat will be generated in the lithium-ion battery energy storage system due to the electrochemical reaction and internal resistance heating during the charging and discharging process, and the heat generated will cause the temperature of the energy storage system to rise.
