摘要
中低速磁浮列车悬浮蓄电池在330V电网的能量调节、补偿以及悬浮电源失效时作为紧急备用电源起到重要作用。基于中低速磁浮列车的悬浮电网特点,分析车辆对悬浮蓄电池的需求,研究蓄电池匹配的类型、相关标准以及电压、节数、容量等参数,推选一种高倍率的磷酸铁锂满足车辆的轻量化、高能量密度、高安全性要求,并通过相应的运营考核验证。
The suspension battery of medium and low speed maglev train plays an important role in adjusts compensation the energy of 330V power grid,and the emergency backup power supply when the failure of DC converters for the suspension.Based on suspended grid characteristics of medium low-speed maglev train,analysed vehicle demand for suspension storage battery;researched the battery matching types,related standards and parameters such as voltage,section number,capacity;choosed a high ratio of lithium iron phosphate meet requirements of vehicle lightweight、high energy density、high security and so on,meanwhile through the corresponding operational assessment validation.
