| 摘要:针对户用储能100 Ah锂离子电池组的热场调控问题，设计了面向电池组温度场变化及其分布管控的浸没式静态温控方案。研究了工作温度、非浸没和浸没形式对电池组温变行为、升温特性和充放电效率的影响。结果表明：电池组的升温幅度随工作温度的降低而增大，尤其在-40 ℃极寒环境下，其0.5倍率放电升温幅度高达50.0 ℃，而在酷暑40 ℃环境下的升温幅度不足7.0 ℃。电池组在常温25 ℃浸没液冷状态下（0.5倍率充、放电）的升温幅度相较于非浸没状态可被多削减3.3 ℃，其温度可被有效控制在36.0 ℃以内。 |
| Abstract:To address the thermal field regulation challenges of a 100 Ah household energy-storaging lithium-ion battery pack， a liquid-immersed static cooling approach was designed to manage temperature field variations and distributions of the battery pack. The effects of operational temperature， non-immerged versus liquid-immerged conditions on temperature change behaviors， heat generations， and charge-discharge efficiencies of the battery pack were investigated. Results show that the temperature rise increases as the operating temperature decreases. The temperature rise was up to 50.0 ℃ at a 0.5 rate discharge in an extreme cold environment of -40 ℃， while it was less than 7.0 ℃ in a hot environment of 40 ℃. Under ambient submerged liquid cooling （ambient temperature， 0.5 rate charge/discharge）， the battery pack’s temperature rise was reduced by 3.3 ℃ compared to that of the non-immerged status， effectively controlling temperatures within 36.0 ℃. |
