2、电力操作电源系统方案  Solution for electric operation power supply system


    


【方案介绍  Solution introduction】

AC I路和AC II路采用一主一备的运行方式,一路异常时,另一路自动投入运行(也可手动切换)。充电模块进行AC/DC整流后的DC电源一方面给电池充电,另一方面给负载供电。直流输出异常时,由蓄电池为负载供电。

AC line I and AC line II respectively are master and standby operating circuits; when one is abnormal, the other one will be automatically put into operation (also they can be manually switched). After AC/DC rectification of charging module, DC power supply will, on one hand, charge battery; one the other hand, it will provide power for load. When DC output is abnormal, the battery will supply power to the load.

【蓄电池在线均衡管理方案   Online balanced management of batteries】

蓄电池自动在线均衡,能够自动在线对每一节电池进行检测和充放电管理,利用先进的电池管理技术(硬件和软件相结合的电池管理),使整组电池中的每一节的单体电池都在良好的的状态下工作,且整组电池具有较好的一致性,极大的延长了电池的使用寿命(可达7-8年)。

Through battery automatic on-line balancing, detection and charging and discharging management can be made on line for each battery; through the advanced battery management technology (a battery management technology through combining hardware with software), each battery cell in the whole battery pack can work in good condition and the whole pack of batteries have better consistency, so that the service life of the batteries are greatly extended (up to 7-8 years).

【全远动系统方案  Full telecontrol system solution】
