摘要
柴油汽车应采用12V/24V电系共用电路。比较几种采用12V/24V电系共用电路的办法,基本思路是将两组12V蓄电池串联后接24V用电器,其中一组蓄电池接12V用电器。为解决蓄电池存电不平衡问题,可在线路中增加一个充电补偿器或加一中性点电压充电回路,但其结构较复杂,12V与24V易串电而损坏电器。分析指出12V/24V共用电系最好采用电源启动转换继电器,启动时,将两组并联的蓄电池转换为串联,非启动状态时恢复成并联。
It is better for diesel vehicles to be equiped with 12V/24V dual system. The paper analyzes serval designs of such dual circuit. The basic concept is using two groups of 12V batteries in series and then connect with 24V load, of which one group is connected with 12V load. In order to keep the balance between the two groups a charge compeusator or a neutral point is added in the charging circuit;but this arrangement is rather complicated. So, it is better to use a starting supply changing relay. At starting, let the two groups be in series and return into parallel in normal running of engine.
