1 OVERVIEW
BAC2410BST Battery Charger applies up-to-date switching power supply device, and is designed
especially for meeting the charging characteristics of lead-acid engine starter battery. It is applicable for
long-term supplement (floating) charging and 24V battery pack.
2 PERFORMANCE AND CHARACTERISTICS
It has the following characteristics.
It employs switching power supply structure, with wide voltage range of input current, small case
dimension, light weight, and high efficiency features.
a) Two-stage charging method or three-stage charging method can be used automatically according to
needs (Three-stage: BOOST and B- are short circuited; Two-stage: BOOST is hung up;), both of
which are designed based on battery charging characteristics, which prevents lead-acid battery
over charging, and prolong the battery life to the most degree;
b) Build-in PFC circuit, which can calibrate the power factor above 0.99;
c) Build-in current protective circuit, which can give effective protection when overcurrent output, short
circuit, or reverse connection occurs, and can recover output when above circumstances are
eliminated;
d) Applicable for 24V battery pack charging, rated charging current 10A;
e) External LED status display: Green means full power indication; Red means charging indication;
3 CHARGING PRINCIPLE
Fig. 1 Three-stage Charging Curve
Three-stage method is employed when charging is performed according to the battery charging
characteristics.
— First stage of charging mode is Constant Current. When battery terminal voltage is low and charging
current is rated 10.0A, large current charging makes battery power increase rapidly, which is called
Bulk Charging. The typical characteristic is red indicator is light on always.
