1 OVERVIEW
BAC150CAN is a kind of battery charger with intelligent multi-functions, which is specially
designed for genset lead-acid battery to meet the charging characteristics. It is suitable for 12V/24V
battery with maximum10A output current.
2 PERFORMANCE AND CHARACTERISTICS
BAC150CAN has the following characteristics:
1) Switch power supply structure, wide high voltage input, small size, light weight, high efficiency;
2) It can work automatically by the method of two-stage or three-stage as required. The two
methods both are designed according to battery charging characteristics, and can prevent
lead-acid battery overcharging, which extremely improves the battery life span;
3) Built-in PFC is designed, so when the output terminal is connected reversely, it shall be AC power
supply, which can effectively protect the charger. When the reverse connection is removed, it
shall recover the output automatically;
4) Multi-function output port is designed, and it can be configured on PC. Low output level is active.
5) Multi-function input port is designed, and it can be configured on PC. Low input level is active.
6) Temperature sensor port is designed, which can monitor the battery temperature of current time;
and it also has temperature compensation function, which can effectively prevent over high
battery temperature;
7) Standard RS485 serial communication interface, CAN communication interface, and USB
communication interface are designed;
8) LED display: Charging status indicator, and alarm indicator.

3 CHARGING PRINCIPLE
Fig. 1 3-Stage Charging Curve Gragh
Three-stage charging method is applied for the charger to work according to the battery charging
characteristics.
1) The first stage is ‘Constant Current’ mode. When the terminal voltage is comparatively low, the
charging current is small, which effectively prevents the battery from damaging because of high
temperature, calling ‘low voltage trickle charging’. When the terminal voltage gets high, the
charging current changes to rated current, which makes the battery electricity increasing rapidly.
This process is ‘quick charging’.
2) The second stage is ‘Even Charging’mode. After constant current mode, the voltage gets up to
the even voltage value, and at this time the charger keeps constant voltage output. The charging
current slows down, and the terminal voltage also slowly keeps at the value of even voltage.
3) The third stage is ‘Float Charging’mode. After the above two stages, the charging is basically
completed and output voltage of the charger switches to float voltage automatically. Charging
current also drops to float current. All white LED indicators are illuminated always. Afterwards the
charging current only offsets the battery self-discharge and longtime charging is unharmful for the
battery.

Two-stage charging method is applied for the charger to work according to the battery charging
characteristics.
1) The first stage is ‘Constant Current’ mode. When the terminal voltage is comparatively low, the
charging current is small, which effectively prevents the battery from damaging because of high
temperature. This process is called ‘low voltage trickle charging’. When the terminal voltage gets
high, the charging current changes to rated current, which makes the battery electricity increasing
rapidly. This process is ‘quick charging’.
2) The second stage is ‘Float Charging’mode. As the electricity gets higher and higher, the charging
current is getting smaller. When the current is below 0.5A, the battery is fully charged. Then the
charging current offsets the battery self-discharge and longtime charging is unharmful for the
battery.

NOTES:
1) Because there are diode and current-limiting circuit inside the charger, it can be used together with charging
generator, and it is needless to disconnect the charger when cranking.
2) When this is applied on the genset, as charging current is very large, it shall produce voltage drop in the charging
wire. So this is recommended that charging wire shall be separately connected to battery terminal, aiming to avoid
disturbance on sampling precision.
