Charging algorithm This is the
"European" charge algorithm that does not float charge the battery at the last
stage, but still keeps it maintained. (see the graph below) |
Constant current/constant
voltage |
Stage 1 slow start, precharge
function for deeply discharged packs |
Stage 2 bulk charge stage. 2 amps is
applied to the battery until the voltage rises to 21 volts |
Stage 4 constant voltage state until
the charge current falls to 400mA |
Stage 5. The charger turns off. |
