Jan Engelhardt, M et al. proposed energy management strategy for a
hybrid EV fast-charging station An encouragement towards sustainable lifestyle,
combining two best ways of tackling pollution on road. We have solar powered
Electric Vehicle(EV) charging stations that help you keep a check on your carbon
footprint as you switch to EV for your daily transportation needs[4]. These chargers
are efficient and self-reliant to provide you a hassle-free experience with the just
blooming arena of EV.Sun-AP prides itself on presenting to its Indian clients the best
in class and latest technological innovations from Global Leaders and brands.
Panasonic and Fimer-ABB have been leading distributors in EV Charging Station
setups. Together with Sun-AP Eco Power, the aim is to create quality customer
experience through and out.
Jayasree V, M et al. proposed a solar PV-based EV charging station
with a bidirectional DC-DC converter (BDDC) for battery charging and discharging.
Amidst growing environmental and energy concerns, electric vehicles (EVs) are
potential solution for reducing carbon emission. All-electric green energy objectives
heavily rely on standardization of electric vehicle service equipment (EVSE),
associated protocols, smart chargers and battery technology[3]. However, no generic
approach for EVSE for charging different categories of electric vehicle exists.
Therefore, in this paper, an off-board unidirectional conductive type DC fast charger

for light and heavy electric
vehicles is presented. The converter is adaptable for charging of light as well as heavy
electric vehicles. The proposed charger is based on resonant series converter with
adaptable restructured multiplier rectifier. The restructuring element for adaptable
rectifier is a simple bi-directional switch. The doubler configuration is recommended
for light electric vehicles (400V Class) while quadrupler configuration is
recommended for heavy electric vehicles (800V Class). In this paper, both the
configurations and their associated operation modes are explained with respective
waveforms. Further, all semiconductor switches and rectifier diodes are naturally soft
switched owing to resonant converter above resonant frequency operation for
minimizing losses[6]. The charging rates and power levels can be scaled up or down
by adopting modular approach. To validate the presented theoretical analysis, a 1.25
kW hardware prototype is designed and tested in the laboratory and experimental
results are presented.
Sravani Y, M et al. proposed a solar PV-based EV charging station that
connects to a three-phase grid, ensuring both efficient charging and power quality
enhancement A new method of battery charging and motor controlling of an electric
vehicle (EV) is disclosed in this paper. The entire system consists of two major
divisions, those are, EV charger and motor controller, which determine the
arrangement of the battery, acting as load or source, and the motor that comes into
action during the driving mode[8]. Both the charging and motor control can be

performed by two separate highly efficient DC-DC converters named as TA converter
which is a Buck-Boost by its nature. While charging a battery it is necessary to make
the charging process effective. Microcontroller employs to control all parameter of
EV in all conditions.
