An Alternative PWM Controlled High Efficient Solution for 60V Electric Vehicle Charging System to Replace Typical Iron Core Charger: Technical Performance Assessment and Comparison of Efficiency

Abstract

Easy bikes or electric auto-rickshaws are the foremost commonly used electric vehicle in Bangladesh. Mainly, iron core transformer-based bulky chargers with an efficiency of up to 75% are employed to charge quite 1 million easy bikes daily without any smart controls. Implementation of power electronics-based charger ready to operate in additional than 90% efficiency which might reduce the power losses from the utility grid. A high capacity synchronous buck converter based charger with automated charging current controlling topology is proposed during this paper. A high-frequency system makes the circuit compact and light-weight. After the simulation by using PROTEUS software, a light-weight prototype of a straightforward bike charger is build and its performance is evaluated. The efficiency and its maximum rated power are observed and compared with the typical charger.
