12V, 24V, 36V, 48V Lead-acid Battery Charger
A battery charger is a device used to put energy into a secondary cell or (rechargeable) battery by forcing an electric current through it.
The charge current depends upon the technology and capacity of the battery being charged. For example, the current that should be applied to recharge a 12 V car battery will be very different from the current for a mobile phone battery.
The Battery charger is professional designed according to the power battery of electric vehicles equipment. It use the advanced soft switch technology, with small size, convenient installation, high conversion efficiency, running fully loaded for a long time, stable output current, large capacity, high reliability, long life features etc. With short-circuited protect, low-voltage protect, overheated protect function. The long delay digital counter can ensure the battery from the constant voltage to the float charge reliably every time. Avoid the lost control of battery heat caused by the the hight temperature. Let the damage of battery drop to the lowest caused by the dehydration and the polar plate vulcanize which are the two general problems of charger.
Operating mode of 4-step battery charger:
Pre-charge mode: In order to protect the battery and extend its life, the battery’s internal resistance is too large or voltage is too low because the discharged time is too long or it is not used for a long time, the charger will supply low output current for the battery automatically. When voltage of the battery rises to the given voltage value, the charge mode will turn to constant current charge mode automatically.
Constant current mode: The charger supply constant charge current for the battery.
Constant voltage mode: Using the pulse width modulation(PWM) tech to control the charging current and output voltage of the charger which ensure the battery is charged fully and avoid over charged.
Floating charge mode: When the voltage of the battery is closing the value of the constant voltage mode, and the current cut down to the given current gradually, that means the battery power is full, then the pilot lamp will turn green and the fan will stop working. The charger will turn the mode into floating charge mode automatically. At this moment, the battery can be stopped charge or kept on floating charge.
