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 maximum 5A output current.
PERFORMANCE AND CHARACTERISTICS
BAC150CAN has the following characteristics:
- Switch power supply structure, wide high voltage input, small size, light weight, high efficiency;
- It can work automatically by the method of two-stage or 3-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;
- 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;
- Multi-function output port is designed, and it can be configured on PC. Low output level is active.
- Multi-function input port is designed, and it can be configured on PC. Low input level is active.
- 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;
- Standard RS485 serial communication interface, CAN communication interface, and USB communication interface are designed;
- LED display: Charging status indicator, and alarm indicator.
CHARGING PRINCIPLE
Three-stage charging method is applied for the charger to work according to the battery charging characteristics.
- 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’.
- 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.
- 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.
- 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’.
- 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
- 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.
- 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.
