Battery Intelligent Fast Charger 48V/70A for cleaning machine and sweeping car

Smart Fast Charger

Introduction

   This charger could charge for WET or VRLA(GEL/AGM) Lead-acid battery.

   We use nonlinear control technology which designed by our company, the charger in high-effiency,low harmonic wave,long life,reliable, the performance reaches high level in the market.

Air-cooled AC380V input, suitable for charging 48V battery, the maximum output current of 70A.

Applying the switching power supply technology and intelligent charging technology, According to the battery charge current capacity, automatic charge strictly according to the characteristic curve of the battery , charging mode is three stages style as "constant → (average charge voltage value) constant voltage reducing current → (automatic identification converted) trickle float" the charger communicates and talks to the battery, solves the charge rate limitation of the battery, saves the charging time for you.

Parameters

Automatic Charging Process  

Trickle → constant current → constant voltage(pulse)→ costant current(time limit)→ full

Charging Curve

Protetion function

Automatic temperature compensation function

When temperature higher or lower 25℃, charger output compensate  -50mV/℃ or +50mV/℃ automatically.

Equalized charging function  

When battery is full, press"stop",charger stop working, and press"Equalized charging"(light on),and then press"on", charger will equalized charge automatically.

Automatic equalized charging function

When battery is full, charger will keep time 5 hours, after 5 hours if the battery is still "online",charger will start equlized charging
