摘要:针对大规模锂电储能用280 Ah电池模组的热失控管理问题，采用浸没式液冷温控方案对模组热失控的行为进行管控。研究了电池模组在浸没、非浸没情境下的热失控传播行为，及其在不同类别浸没液和不同热失控触发方式下的热失控行为特征。研究结果显示，模组在非浸没情境下发生了热失控传播，其峰值温度高达367.8 ℃，而在浸没情境下未发生热失控传播。模组在过充情境下的热失控峰值温度为227.1 ℃，高于其在针刺情境下的峰值温度214.7 ℃。碳氢基合成油与二甲基硅油对模组热场管控和热失控抑制的能力相当，前者在疏散模组热量方面的能力较强，后者在削弱模组峰值温度方面的能力较强。
Abstract:For the thermal runaway management issue of large-scale lithium battery energy storage using 280 Ah battery modules， a submerged liquid cooling thermal control solution was employed to regulate the thermal runaway behavior of the modules. The thermal runaway propagation behaviors of battery modules under submerged and non-submerged conditions， as well as the characteristics of thermal runaway behavior under different types of immersion liquids and different thermal runaway triggering methods， were studied. The research results show that under non-submerged conditions， the module experienced thermal runaway propagation， with a peak temperature of 367.8 ℃. In contrast， under submerged conditions， the module did not exhibit thermal runaway propagation. Among the submerged scenarios， the peak temperature during thermal runaway triggered by overcharging was 227.1 ℃， higher than the peak temperature of 214.7 ℃ observed in the nail penetration scenario. Hydrocarbon-based synthetic oil and dimethyl silicone oil demonstrated comparable capabilities in managing the thermal field and suppressing thermal runaway in the module. The former exhibited stronger heat dissipation capabilities， while the latter was more effective in reducing the peak temperature of the module.
