72V eTricycle Smart Charger

There are many ways to slow down battery sulfation depend on you use and maintenance properly everyday. Improperly charge and discharge is the major reason of battery early failure. Thus, the first important way is not to keep a lead-acid battery over-charged and deep discharged  frequently. Remember it forever: Don`t  Deficit  and Over Charged  

Based on the battery type, use an better charger in a well ventilated place that is able to deliver a continuous, temperature compensated "float" charge at the battery before it being fully charged. If over-charged(12V cell charging volt higher than 13.6V),  the cell`s electrolyte will loss H₂O very fast  which raise gravity of acid resulting in sulfation heavier and plates corrosion.

Don`t keep the battery in a wrong charging current value,  use  the right charger at the battery manufacturer's recommended float or maintenance voltage for a fully charged battery. The best charging current value is 0.1C(e.g.  1 cell capacity is 100Ah, C=100A, the charging Current value =0.1C, 10A), the Max Recommended Value is less than 0.3C. If cell charged at high charging rate, the cell voltage will reach a high value, resulting in over charge and H₂O separation.  Thus, well charge management could slow down sulfation. Our 72V eTricycle Smart Charger will be your best partner which can help you eTricycle Power Battery Maintenance to prevent sulphating and H₂O separating,  no overcharged , temperature compensated.

72V eTBC150L is eTricycle Intelligent Maintaining Charger, is more than a battery charger and battery saver. During the charging cycle every day, our patented desulphation pulsing constantly works to minimize and reduce naturally occurring battery sulfation as a kind of eTricycle Power Battery Maintenance real-time mode. By this way of charging, your EV power battery will be charged deeper, maintained greater reserve capacity extend battery life doubled or more. As you will read, this 72V eTBC150L eTricycle iM Battery Charger for electric bicycle or tricycle is a multi-functional charging maintenance system developed by us based on our multi-year research results used for power battery of electric vehicles. It is applicable to digital pulse charging, non-destructive repair and pulse maintenance desulfation of all types of lead batteries in 72V/10Ah~150Ah. As well as called it Battery Desulfation Smart Charger or EV Smart Battery Saver.

TECHNICAL FEATURES

• Adopt multi-stage constant current pulse charging mode. When starting charging, it charges the power battery quickly through a large duty cycle, and when the charging battery voltage is close to producing gas stage, smartly reduce the pulse charging current stepwise gradually.
• Each charging pulse is followed by a depolarizing pulse of 1~3 times the charging current, to ensure elimination of polarization voltage and cooling battery plates, so as to improve capability of charge acceptance.
• Adopt temperature compensation function. Calculate the gas-produced voltage point of VRLA battery based on the ambient temperature tested by temperature sensor; at the same time, analyze gas-produced voltage and make dual judgment through the raise of dv/dt not affected by temperature, which effectively solves the battery sulphation caused by low temperature undercharged as well as water loss and thermal runaway caused by high temperature overcharged.
• In each charging pulse, special battery repair pulse is added to restrain sulphation of lead-acid battery; harmonic components of this pulse resonate with the lead sulfate large crystalline molecule on the battery plate and destroy the condition for forming lead sulfate large crystalline, it also has the function of breaking the lead sulfate large crystalline.
• Automatically detect connection of the charged battery. The charging switch is not started when the battery is not connected, in order to avoid electrical erosion of the battery plug and damage due to accidental short-circuit output.
• Automatically identify 72V battery voltage and shift the output polarities of the charger. It can adapt to all the popular electric tricycles on the market.
• Indicate battery voltage, and various charging and repair states by LED.
• Have the function of battery desulfation. Produce special battery desulfation pulse, automatically repair the batteries exceeding the storage term in the processes of circulation, storage and transportation and use, and recover chargeability of the batteries with sulfation failure.
• Embedded smart battery management chip. Users can know the battery status according to the capacity.
