FAQ

Q: What models should I choose if we are to activate single Cell?
A: Kongter offers two models, BCD-3932T and BCD-3933T, for charge, discharge and activation of single cell. BCD-3932T is for measurement of 1.2V, 2V, 4V, 6V, 8V and 12V with max charge and discharge current of 100A, while BCD-3933T is for measurement of 6V and 12V ONLY with max current of 50A.

Q: What models should I choose if we want to activate battery String?
A: K-3986 series customized units are used to charge, discharge and activate battery String in single device. For example, if you want to test 48V with discharge current of 200A and charge current of 100A, you will need a customized model of 48V 200A (discharge)/48V 100A (charge).

Q: What is the principle of battery activation?
A: The charge and discharge functions in BCD-3932T. BCD-3933T and K-3986 could be used individually or comprehensively. When used comprehensively, lag-out battery will experience low-volt constant current charging and discharging in one or multi-circles (1~99). By activating the disabled Active-Material on battery electrode plate, it amends the battery malfunction caused by chemical failure and thus boosts the capacity of batteries.

Q: Can I monitor voltage of each cell during charge or discharge?
A: With optional DAC (Data Acquisition Case), you could view complete data including voltage value of each cell in PC software and K-3986 during measurement.

Q: If I do not have DAC, can I still use the PC software to monitor other data during measurement?
A: Yes, you could.
