Functions

1 Check of discharge test

1.1 can set continuous discharge current, constant-current discharge according to the discharge to be set, monitoring the voltage of battery pack during the process of discharge, measuring the capacity of battery.

1.2 set of various discharge stop conditions

   A. The total voltage of battery pack      B The voltage of single battery

   C. Discharge time                      D Discharge capacity

1.3 Applicable to a variety of single cells: 2V, 4V, 6V, 12V (other voltage can be customized)

2、Quick test function

Short time discharge (around 10-20 minutes), quickly test the internal resistance and discharge capacity of single battery, quickly identify the performance of battery.

3、When power failure or actual load discharge, on-line automatically monitoring the voltage of single battery, the voltage of battery pack and discharge current, record the discharge capacity of the battery, ensure the judgment of battery status.

4、Monitoring the charging voltage after discharge. After discharging, when the battery pack is charging by the charger, this device can monitor the voltage of single battery and pack battery during the process of charging, it can monitor the charging current (equipped with current clamp) and set the alarm.

5、Wireless monitoring function to PC. Realize the PC to discharge monitoring system for wireless data monitoring within 100M, alarm function.

6、Data management

Perfect computer management and analysis monitoring software, with strong function of data analysis and processing, use advanced mathematical models to make comprehensive computational analysis for  a number of measurements of the battery, accurately judging the battery performance, and check real-time operating status and historical data of the battery, report each parameter, curves and generate reports.
