Development and Performance Examination of Switch Mode Power Supply based Battery Charger for Electric Vehicle.

Abstract

Objectives: The study’s primary goal is to investigate a Switch Mode Power Supply (SMPS)-based battery charger for electric vehicles (EV) and compare the use of various charging techniques. Methods: This study provides ideas for the requirements of an SMPS-based battery charger; design and development of the charger; and operation of the charger with different charging techniques. Further, the development of the proposed charger, its testing and performance examination are carried out. This study also gives details about circuit components; circuit selection criteria of an SMPS-based battery charger; charging methods; and technical specifications of the charger. Verification and testing of the proposed charger is also done with the help of a 24 V battery. Findings: It is found that the proposed battery charger can be more advantageous than conventional battery chargers in a variety of ways, including improved efficiency (nearly 88%), light weight, better protection (reverse battery connection, short circuit, overload), and reliable operation (no need to monitor, automatic cut off, and so on). Novelty: Work was done for the development of an SMPS-based battery charger to eliminate existing issues as mentioned in the findings with traditional charger systems. The proposed charger helps to eliminate the sulfation effect on lead acid batteries to improve battery life (50–100 cycles). It helps to not only promote the ”Made in India” scheme but also mass adoption of electric vehicles. Keywords: SMPS based charging system; microcontroller; IGBT; sulfation; lead acid battery
