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.
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.
The storage material energy storage capacity (ESCmat) is calculated according to the type of TES technology: i. ESCmat for sensible = heat · TES . . Eq. 4 cp.mat: Specific heat of the material [J·kg-1·K-1]. Mmaterial: mass of the storage material [kg]. ∆Tsys: Design temperature difference of the system [K].
However, only the surface temperature of the lithium-ion battery energy storage system can be easily measured. The estimation method of the core temperature, which can better reflect the operation condition of the lithium-ion battery energy storage system, has not been commercialized.
The proposed network can accurately estimate the core temperature in the next 10 s and provide the early-warning signal according to the measurement of the previous 20 s, which saves significant time for the thermal protection of the large-scale energy storage system.
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.
