What is it about?
This paper deals with design and development of a light electric vehicle (EV) charger. This EV charger operates in bulk charge as well as float charge mode with the battery deep discharge cutoff to enhance battery life. Its power converter is of 85W rating having operating voltages from 36V to 42V with 2A maximum current in bulk charge mode. Test results are presented for a 36V, 10Ah-20Ah battery, which is commercially used for electric cycle or equivalent EV application. The input voltage for this power converter is for universal input voltages (90VAC-265VAC/47Hz-63Hz). The AC-DC converter power switch operates in quasi-resonant mode for high efficiency in wide input voltage range. The converter size as well as thermal parameters are well within the limits as observed in test results.
