72V Electric Tricycle Maintenance Charger

This 72V Electric Tricycle Maintenance Charger is a intelligent charging repairing device developed by us based on our lots of research results used for Electric Tricycle power battery. It adopts 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. It is applicable to digital pulse charging, non-destructive repair and pulse maintenance desulfation of all types of lead batteries in 72V/10Ah~150Ah. It is worthy of the name Electric Tricycle Battery Life Extender

The Electric Tricycle Battery Regenerator has the multi-stage patented pulse charging technology specially for 72V/10Ah~150Ah battery bank as power battery of electric vehicles. This innovative, Battery Smart Charger automatically knows what to do and how to charge as a perfect Electric Tricycle Battery Repairer and Battery Life Saver, so you don't worry about how to install it just as a power expert. Unlike other common chargers on the market, this intelligent device adopt the proper charge current and different stages upon cell itself to avoid the risk of unsafe or improper charging, such as over-charged and under-charged.

TECHNICAL FEATURES

• 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.

iM Charger 72L is intelligent maintenance 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 Electric Tricycle Battery Repairer in 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 well as called it Battery Desulfation Smart Charger or Smart Battery Saver for electric bicycle.
