Battery Charger for E-vehicle

e-rickshaw battery charger

  • Battery Charging is a complex electro technical process, in which the discharged electrical energy must be replenished from the electrical network.
  • Quality of the charging process is critical to the health & longevity of the battery.
  • Therefore battery charger plays a vital role in life & performance of today’s batteries
  • In low voltage & low power application PWM based SMPS automatic charger is the most economic, efficient and versatile solution.
  • ESI SMPS Chargers are designed to provide a perfect balance between maximum utilization of battery capacity and safe charging



Input voltage 170-270V, 1 Ph, 50 Hz
Input current < 3.5A AC
Boost charging current  10A DC ( constant current)
Line regulation ± 2%
Load regulation ± 2%
Ripple voltage at resistive load <1% RMS
Boost to Trickle change over voltage 60V DC
Boost/ trickle change over Automatic,
Efficiency Better than 80%


Boost/trickle change over saves Battery from over charging and over-heating.
