Original BCC10A 12V MEBAY Generator Intelligent Automatic Battery Charger PEMP

1. Summary

The charger is specially designed for the lead-acid battery used in the engine. It adopts the three-stage intelligent control mode of constant current fast charging, constant voltage evenly and trickle floating charging. It can be charged for a long time without damage to the battery. It can maintain the full state of the battery and ensure the service life of the battery. The charger can be used in parallel with the engine charging generator without disconnecting the charger during the operation of the engine.
 

2. Main Features

The use of aluminium for heat dissipation, good heat dissipation and high interference resistance.

Using advanced switching power supply mode, wide AC input voltage range.

Two-stage charging method or three-stage charging method can be used automatically according to needs to maintain battery power automatically.

Three-stage: BOOST and B- are short circuited; Two-stage: BOOST is hung up.

Build-in PFC circuit, automatic adjustment of calibrated power factor.

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.

Applicable for 24V/12V battery pack charging, rated charging current 10A/12A.

It has LED led,  Green means full power indication; Red means charging indication.
 

3. Charging Principle

Three-stage Charging Curve

The charger adopts a three-stage intelligent control mode in accordance with the characteristics of lead-acid batteries.

The first charging mode is "constant current mode", when the battery voltage is lower than the preset value, it is a constant current charging stage; the charging current is rated at 10.0A(12.0A) , the high current charging makes the battery power rise rapidly, the rising process is a fast charging state, the performance is character by the red charging indicator light is always on.

The second stage of charging mode is "constant voltage mode", when the battery voltage rises above the preset value soon after charging in constant current mode, the charging current decreases as the battery voltage rises, the charger maintains constant voltage output at this time, the charging current decreases slowly and the terminal voltage of the battery is slowly stabilised at the average charging voltage value, during this process the red The charging indicator lights up. The internal timer starts timing when the evenly state is reached and the charging current drops below 1.0A to float charge mode;

 The charger enters an evenly charge state: when the charging current is greater than 1.0A and less than10.0A(12.0A).

The third stage of charging mode is "float mode", after the battery has been charged in both modes, the battery is basically full, the charger output voltage automatically switches to the float voltage of 27.6V(13.8V), the charging current drops to 1.0A, the performance characteristics of the red charging indicator goes out. The float mode charging current offsets the self-discharge of the battery and maintains the battery in a fully charged state without the need to disconnect the charger and has no effect on battery  life.

Two-stage Charging Curve

The charger adopts a two-stage intelligent control mode in accordance with the characteristics of lead-acid batteries.

The first charging mode is "constant current mode", when the battery voltage is lower than the preset value, it is a constant current charging stage; the charging current is rated at 10.0A(12.0A) , the performance is character by the red charging indicator light is always on.

The second stage of charging mode is "evenly charge mode", when the battery voltage rises above the preset value soon after charging in constant current mode, the charging current decreases as the battery voltage rises, the charger maintains constant voltage output at this time, the charging current decreases slowly and the terminal voltage of the battery is slowly stabilised at the average charging voltage value, during this process the red the charging indicator lights up，reached evenly state. the charging current drops to 1.0A, the performance characteristics of the red charging indicator goes out. The float mode charging current offsets the self-discharge of the battery and maintains the battery in a fully charged state without the need to disconnect the charger and has no effect on battery  life.
