摘　　要：利用磷酸铁锂电池与铅酸蓄电池不同的充放电特点,开发了基于磷酸铁锂电池与铅酸蓄电池并联的混合动力电源系统,并设计了新型充放电制度.充电时铅酸蓄电池优先充电,使其免于欠充电;放电时磷酸铁锂电池电优先放电,铅酸蓄电池后放电,使铅酸蓄电池处于浅循环.这种充放电制度可以明显延长混合系统中铅酸蓄电池使用寿命,并且混合动力电源系统同时具有磷酸铁锂电池倍率性能优、循环寿命长及铅酸蓄电池价格低廉等特点,在动力电池领域有巨大的应用前景.By utilizing the differences of the charging and discharging characteristics between lithium iron phosphate batteries and lead-acid batteries,a new parallel hybrid power battery system with lithium iron phosphate batteries and lead-acid batteries and new charge/discharge system are developed.When charging,the lead-acid batteries attain the priority,so that lead-acid batteries can avoid to be charged less.When discharging,lithium iron phosphate batteries discharge with priority,while the lead-acid batteries are on the contrary,so lead-acid batteries can work in a state of shallow cycle,which can prolong the service life of the lead-acid batteries in the hybrid system.The hybrid battery system can effectively combine the advantages of both lithium iron phosphate batteries and lead-acid batteries,such as excellent discharge rate performance,long cycle life and low cost et al,which make the system suitable for the application in the field of power batteries.
