摘要
依据库仑效率、能量效率及系统效率等3个指标,探究充放电电流、充电容量对单液流锌镍电池能量损失和工作效率的影响。充放电电流从80 A变化到180 A时,库仑效率和系统效率变化幅度较小,能量效率随着充电电流的增加而降低。充电容量从200 Ah变化到300 Ah时,库仑效率、能量效率以及系统效率都会随充电容量的增加而减少。
According to Coulombic efficiency,energy efficiency and system efficiency,the effects of charge-discharge current and charging capacity on energy loss and working efficiency of single flow zinc-nickel battery were investigated. When the chargedischarge current was changed from 80 A to 180 A,the Coulombic efficiency and system efficiency changed little and the energy efficiency decreased with the increase of charge current. The Coulombic efficiency,energy efficiency and system efficiency decreased with the increase of charging capacity,when the charging capacity was changed from 200 Ah to 300 Ah.
