摘要
分析电动公交车充换电站的主要安全问题,在正常运行的基础上选择可靠的充换电模式,实现锂离子动力电池储备量的最小化,降低站内火灾爆炸事故风险。采用AHP法建立充换电模式优化模型,确定最佳充换电方案综合评判体系各级指标的权重,结果表明即换即充为最佳方案。对站内电池安全库存展开优化设计,计算该站需要配备的公交车数量、备用电池数量、换电工位及充电功率。模型计算结果符合充换电站实际运行规律。
Safety issues in electric bus charging/battery swap station were discussed in this work. On the basis of the normal operation, choosing reliable charging/battery swap mode and minimizing the power Lithium-ion battery storage volume could decrease its accidents risk, such as fire and explosion. Here AHP method was used to build optimal charging/battery swap mode model and then to find out the ratio of the influence fac- tors in evaluation system. The result showed that the mode of charging immediately after battery swap was the optimal choice. Afterwards the safety optimization of battery inventory was performed to calculation the bus quantity, emergency bat- tery quantity, battery swap workstation quantity and charging power. The simulation results conformed to realistic operation rules of charging/ battery swap station.
