Additional information about chargers at GWL/Power blog.
Application notes: Even though this charger is designed as a fully automatic charger, it is always recommended to operate this charger under continuous supervision and with additional monitoring of the charging parameters for the battery pack. It is necessary to make sure the cells of the battery pack will not be over-charged or misbalanced. We also suggest installing over temperature and fire protection alarms.Check our GWL Technology Blog to know more about the propper charging characteristics of LiFePO4 battery.
Please, make sure that you have set these DIP switches according to your battery chemisty (in case LTO, you have to set 5 or 6 cells)
Connecting charger BMS with BMS123
Charger includes the management connector for BMS. BMS system should control the charging process. There are three states for BMS:
Charger is also fully automatic for stand alone using without BMS connection with advanced processor-controlled lithium battery charging process for 12V nominal voltage. This GWL/Power charger is an industrial battery charger for lithium batteries, that allows charging the lithium cells in a safe and reliable way.
For disconnect charger via BMS123:connect black (GND) from charger to pin 2 on OUT board on charge relay contacts.
For reducing charge current via BMS123:connect black (GND) from charger to pin 2 on OUT board on charge relay contacts.
|Nominal Voltage (V)||12|
|Max. voltage (V)||15.2|
|Charging current (A)||20|
