BS Charger BK15 Mode D'emploi page 6

(Note: If the Fault Indicator LED illuminates Red, please check your connections as it's likely that
the Positive and Negative Leads are reversed. Refer to Trouble Shooting Page for further information)
THE CHARGING PROCESS:
The charging stages and performance are as follows:
ECO Mode
If ac power is connected, and the battery is not connected, after 10 seconds, the charger will
automatically go into ECO mode, this battery charger is built with ultra low power consumption circuit,
When Ac power is presented and battery disconnected, the power drawn is less than 1.8W, equal to
power consumption of 0.05kWh per day; after the battery is fully charged and during long term
maintenance stage, the total power consumption is around 0.15kWh per day.
 The Green LED is fast flashing indicates the ECO mode.
Battery Initial Qualification
When the battery is connected and Main Powers on, the program will automatically run qualification as
the following processes:
- Detect the battery internal impendence and initial voltage.
- Judge the capability of charging current acceptance.
- Diagnose the battery sulphated intensity.
- Check the battery load statues and assess whether it is connected into the vehicle electronic circuit.
The program will determine the next stage subjected to above result of initial qualification.
 The Red LED is ON and Yellow LED is ON, (the initial voltage is at very low level).
Enhanced Battery Rejuvenation
Two alternative- rejuvenation stages work in turn to the stratified electrolyte liquid and lead sulphated
crystal, which is not only dissolve the lead sulphated crystal but also bring the electrolyte fluid to a well-
distributed state, it consists of two alternative stage with high voltage equalizing stage (16V or enhanced
20V) and high peak pulse reconditioning stage (Europe patented).
If the battery is detected under an extreme flat or heavy sulphated stage, further, the program will
automatically detect whether the battery is connected into the vehicle electronic system, if detected the
battery has been connected into the vehicle electronics system, the battery charger will engage a safe
rejuvenation method; which is to run high voltage equalizing stage (16V) and high peak pulse
reconditioning stage alternatively; If detected the battery is not connected into the vehicle electronics
system or battery moved from the vehicle, the program will engage an enhanced equalizing voltage (20V)
and peak pulse conditioning stage for the extreme flat batteries.
If the program detects the battery is slightly sulphated, it will run high voltage equalizing stage (16V)
and high peak pulse reconditioning stage alternatively.
 The Blue LED is flashing indicates the Rejuvenation stage.
