Batteries in power plants, transformer substations, Telecom company and Force communications must provide the equipment they serve with standby power in the event of a power failure. Unfortunately, however the capacity of such batteries can drop significantly for a number of reasons before their calculated life expectancy is reached. This is why so important to check batteries regular intervals, and the only reliable way of measuring battery capacity is to conduct a discharge test. 

On line monitorings: 

Online monitoring for battery string: when the battery pack is under the state of online discharge, uniform charge and floating charge, perform real-time online monitoring for all cells. The monitoring includes string voltage, cell voltage, charge/discharge current, monitoring time of battery string, charge/discharge capacity of battery string and etc.

Discharge Test: 

Perform discharge of constant current taking advantage of intellectualized dummy load after the battery pack is removed from system, set up the parameters of “discharge current”,“discharge time ”,“discharge capacity” ,“final protective voltage of whole pack” and“ final protective voltage of cell”, and the tester could carry out discharge function automatically, display discharge current,battery discharged capacity,the whole pack voltage, cell voltage, discharge time and etc at real time;
