Table 2 Sign Instruction

1. OVERVIEW

BACMXX06 series battery charger is intelligent and multi-function which is specially designed for meet the charging characteristics of the lead-acid engine starter batteries. BACMXX06 battery chargers are divided into 2 types according to the battery voltage: BACM2406 (suitable for 24V) and BACM1206 (suitable for 12V). Both of their maximum charge current are 6A.

2. PERFORMANCE AND CHARACTERISTICS

1. Switch power supply structure, wide input AC voltage range, small size, light weight, high efficiency rate;
2. Users can select automatic two-stage charging process or automatic three-stage charging process as needed. Both the two charging process are carried out according to storage battery charging characteristics to prevent overcharging and significantly prolong battery lifetime;
3. Built-in PFC circuit can calibrate the power factor above 0.99;
4. Built-in current protective circuit for over current protection, short-circuit protection and reverse connection protection. The output will be recovery automatically after the failure is removed;
5. Battery voltage detection ports can detect the battery voltage in real time;
6. Battery low voltage output port; It will output low level immediately after the battery voltage has fallen below the set value for preset delay;
7. Temperature sensor port allows for monitoring the battery temperature in real time and temperature compensation function which can prevent the battery temperature is too high effectively;
8. Mains failure port; It will output low level immediately when the AC input is interrupted;
9. Standard RS485 communication port;
10. BACM2406 charger is suitable for 24V battery; rated current: 6A; BACM1206 charger is suitable for 12V battery; rated current: 6A;
11. LED display: Full charged indication (Green light) and charging indication (Red light).

3. CHARGING PRINCIPLE

Fig.1 Three-stage Method

Charging is performed according to the battery charging characteristics using three-stage method.

The first stage is named as “Constant Current”: 1): Trickle Charge: When the battery terminal voltage is relatively low, then the charging current is low likewise which can prevent the battery damaging due to high temperature. The charging indicator (Red color) status is illuminated. 2): Quick Charge: When the battery terminal voltage is relatively high, the charging current will rise to rated value. Large current charging operation leading to an increase in the electricity quantity of the battery. The charging indicator (Red color) status is flashing rapidly (0.2s/per) as the battery power rising quickly.

The second stage is named as “Absorption Charge”: After the first stage, the battery voltage rises to absorption charge value rapidly, and the charger voltage will keep constant. The battery terminal voltage will stabilize in the absorption charge value with the decreasing of charging current. The charging indicator (Red color) status is flashing slowly (1s/per).

The third stage is named as “Float Charge”: After the above two stage, the charge is basically completed and the Float Charge is started automatically. In this stage, the charger voltage reduces to float voltage and the charger current reduces to float value (Red indicator will extinguish and the green indicator will be illuminated). After that charging current will only neutralize the battery self-discharge. Even long-term charging cannot harm the battery, as charger can keep the battery fully charged and so guarantee long lifetime of the battery.

Fig.2 Two-stage Method

Charging is performed according to the battery charging characteristics using two-stage method.

The first stage is named as “Constant Current”: 1): Trickle Charge: when the battery terminal voltage is relatively low, then the charging current is low likewise which can prevent the battery damaging due to high temperature. The charging indicator (Red color) status is illuminated. 2): Quick Charge: When the battery terminal voltage is relatively high, the charging current will rise to rated value. Large current charging operation leading to an increase in the electricity quantity of the battery. The charging indicator (Red color) status is flashing rapidly (0.2s/per) as the battery power rising quickly.

The second stage is named as “Float Charge”: The charging current will decrease with the rising of battery electricity. The charging indicator (Red color) status is flashing slowly (1s/per). As soon as charging current value falls below 0.3A, the battery is basically charged (Red indicator will extinguish and the green indicator will illuminate). After that charging current will only neutralize the battery self-discharge. Even long-term charging cannot harm the battery, as charger can keep the battery fully charged and so guarantee long lifetime of the battery.

6. OPERATION

Table 6 Wiring Description

NOTE:

1. Because there is diode and current-limiting circuit inner the charger, it can be used together with charging generator, and there is no need to disconnect the charger when cranking.
2. During genset is running, high current will cause voltage drop in charging line, so recommend separately connecting to battery terminal to avoid disturbance on sampling precision.
