Abstract:
The transportation industry is transitioning from conventional Internal Combustion Engine
Vehicles (ICVs) to Electric Vehicles (EVs) due to the depletion of fossil fuels and the rise in nontraditional
energy sources. EVs are emerging as the new leaders in the industry. Some essential
requirements necessary for the widespread adoption of EVs include sufficient charging stations with
numerous chargers, less to no wait time before charging, quick charging, and better range. To enable
a quicker transition from ICVs to EVs, commercial organizations and governments would have to put
in a mammoth effort, given the low number of installed chargers in developing nations such as India.
One solution to lower the waiting time is to have multiple vehicles charging simultaneously, which
might involve charging two- and four-wheelers simultaneously, even though their battery voltage
ratings differ. This paper begins by providing the details of the power sources for EV charging,
the charging levels and connector types, along with the specifications of some of the commercial
chargers. The necessity of AC-DC converters in EV charging systems is addressed along with the
power quality concerns due to the increased penetration of EVs. Next, a review of the existing
research and technology of isolated DC-DC converters for simultaneous charging of EV batteries is
provided. Further, several potential isolated DC-DC converter topologies for simultaneous charging
are described with their design and loss estimation. A summary of the existing products and
projects with simultaneous charging features is provided. Finally, insight is given into the future of
simultaneous charging.
