混合动力汽车低压辅助供电系统充放电管理
Charge and discharge management of low voltage auxiliary power supply system for hybrid vehicle
摘要
Abstract
In view of the short service life and low charging efficiency of low voltage auxiliary power (12 V lead-acid battery),a kind of effective protection for battery and high efficiency of charging and discharging management strategy was put forward by combining with the characteristics of the hybrid hardware structure.The different stages of deficient electric protection mechanisms were formulated according to the monitoring status of battery under the low voltage,and the phase type of charging method was adopted on strong power mode.The results of real vehicle tests verify the strategy can effectively improve the charging efficiency,shorten the charging time,limit the charging current,and prolong the service life of battery to a certain extent.It has important practical value for the hybrid car's battery to achieve more reasonable charge and discharge management.关键词
