·Cell activation:

    Perform cell activation on the state of online floating charge or offline. Users should set up activation and cycling times, single-activation charge time, protective voltage parameters before activation; it can display battery voltage, charge/discharge current, charge/discharge capacity, charge/discharge time and etc; users can set up activation cycling and also stop the activation manually.

·Cell check discharge:

    Perform constant current discharge for cell. Users should set up discharge time, discharge capacity, cut-off voltage and etc before discharge; it can display discharge current, battery discharged capacity, battery voltage, discharge time and etc; users can manually stop the discharge.

·Cell charge:

    When the battery is on the state of online floating charge or offline, it can perform automatic charge for battery, users should set up charge current, charge time, cut-off voltage and etc, the instrument can display charge current, battery charged capacity, battery voltage, charge time and etc; users can manually stop the discharge.

● Features

    ·Data storage: large capacity. Save 10 groups of activation data, 10 groups of check discharge data, and 10 groups of charge test data. Users can query, delete and export the data.

    ·With RS232 interface and USB interface. users can perform long-term historical data storage and analysis.

    ·When the instrument detects abnormal phenomenon of battery or working is abnormal, it automatically stops testing for protecting battery.

    ·The activation adopts integrated design with monitoring unit and power unit. The monitoring unit adopts high-speed A/D and D/A, and power unit adopts new-type parts.

    This software is English designed, and it can automatically create voltage/current histogram, curve chart, and test report (including Excel table and WORD document).
