基于CAN总线的UPS电源电池检测方法

Detecting method for UPS battery with CAN-bus

设计了基于CAN总线的UPS电源电池组集中检测的方法,采用了交流比例法检测UPS电池组中各电池的内阻。该方法中单个UPS电池检测节点即可检测该UPS内各电池的电压和内阻变化,并通过CAN总线与显示及数据处理节点通信,为UPS电源电池,特别是多个UPS电源的维护提供了有用的信息。

Detecting method based on CAN-bus for UPS battery was introduced in this paper,and the scenario using AC proportion method detecting the change of the internal resistance of UPS batteries was proposed.The single UPS battery detecting unit which could achieve the information of voltage and internal resistance of all batteries in this UPS would communicate with the unit of date process and display.It’s useful for maintenance of UPS battery,especially muli-UPS system.
