4-1. Battery Charging Curve

PANcharge1k is a charging voltage adjustable battery charger. The charging voltage is able to be
switched in accordance with the battery voltage of 12V, 24V, 36V or 48V by the battery voltage
setting switch on the charger.
3 Stage Charging
PANcharge1k charges by the 3 stage charging: bulk, absorption charging and floating charging. In
bulk charging stage, PANcharge1k outputs and charges by a constant current. In absorption
charging stage, battery voltage is constant but the current is decreasing, and battery generates
gas.
In the last stage of floating charging, charger charges with constant low voltage, maintains the
battery at 100% state of charge. If the battery does not connect to any load, it is normally charged
with a very low current.
