Types of electric vehicles
Battery Operated Electric Vehicle (BEV or 
EV)
Hybrid Electric Vehicle (HEV)
Plug-in Hybrid Electric Vehicle (PHEV)
Range Extension Electric Vehicles (REx)
Fuel Cell Electric Vehicles (FCEVs)

Battery Operated Electric Vehicle (BEV or EV)
As the name suggests these vehicles are fully 
operated through power generated from a 
battery (Li-ion).
This type of vehicle does not come with the 
traditional combustion engine and thus emits 
zero carbon monoxide or pollutants in the 
atmosphere.
Examples of BEVs: Tesla 
Model 3, BMW i3, Hyundai 
ioniq, Ford Focus, etc.

Hybrid Electric Vehicle (HEV)
This vehicle features both the conventional combustion 
engine & battery-powered electric motor. But the battery 
cannot be charged by plugging in through an electricity 
input/ charging station, instead, it captures energy while 
braking and batteries are charged.
Examples of 
HEVs: Volvo 
XC90, Toyota 
Prius

Plug-in Hybrid Electric Vehicle (PHEV)
  type of EV category from its name. Unlike hybrid vehicles, 
PHEVs battery can be charged through a plug-in socket as 
well as power generated through braking and the car 
operates on the both combustion engine and electric 
powered motor. Benefits of PHEVs are the ability to cover 
shorter distances without using the combustion engine and 
increased range from fuel, battery charging & regenerative 
braking.
Examples of  PHEVs: 
BMW i8, Toyota Prius 
Prime

Range Extension Types of Electric Vehicles (REx)
This type of vehicle features both combustion engine & 
electric motor but most of the driving is done by the electric 
motor only. The internal combustion engine is only there to 
charge the battery if in case it gets low during a journey.
Example of REx: BMW i3
8
Fuel Cell Electric Vehicles (FCEVs)
This type of vehicle stores hydrogen gas in the tank & use 
electric motors like BEV. A fuel cell combines hydrogen with 
oxygen present in the air & generates electricity which 
powers the electric motor. 
Like the BEVs, it does not contain tailpipe and the byproduct 
is only water. There is no need to plug-in as the fuel cells are 
recharged by refilling the hydrogen.
Hydrogen infrastructure is far from reality as of now, which 
is not the case with Charging infrastructure as it has gained 
worldwide momentum.
Example of FCEV: Toyota FCV

What is a EV Hybrid Vehicle
Hybrid electric vehicles are powered by an internal  
gasoline-powered motor and one or more electric motors 
to power it.
Hybrid cars are designed to switch between using 
gasoline and electric power or using both at the same 
time, depending on what’s most efficient at the moment.
Hybrids come in different types, including those that can 
be plugged in to charge their batteries and others that 
just recharge by running the engine or through braking 
It’s called Regenerative.

   Which car is better, EV or hybrid?
If one has a spare gas powered car than going 
for an EV is a good idea as once you the hit 
highway for a long drive the range anxiety will 
kick in. If one can have only one car than as 
far as today is concerned getting a hybrid 
makes more sense.
11
     what is full and half hybrid
Half hybrids have an electric motor that 
assists the gas engine, but always needs the 
gas engine running for it to assist.
Full” hybrids have an electric motor that can 
move the car without the gas engine running, 
though only with electricity that originally 
comes from the gas engine

        Parallel Hybrid Vehicle
In a PHEV, mechanical and electrical powers are both connected to the 
driveline, as shown in Figure  In the case of parallel architectures, good 
performance during acceleration is possible because of the combined 
power  from both engines . 
. Different control strategies are used in a preferred approach. If the power 
required by the transmission is higher than the output power of the ICE, 
the electric motor is turned on so that both engines can supply power to 
the transmission. If the power required by the transmission is less than the 
output power of the ICE, the remaining power is used to charge the battery 
packs . Moreover, mechanical and electric power could be decoupled, and 
the system has a high operating flexibility enabling three modes of 
operation: purely combustion; purely electric and hybrid. Usually, a PHEVs 
are managed in purely electric mode at low speeds, until the battery 
charge state reaches a predetermined low threshold, typically 30%.

   Series hybrid electric vehicles (SHEVs)
Series hybrid electric vehicles (SHEVs) involve an internal 
combustion engine (ICE), generator, battery packs, capacitors 
and electric motors . SHEVs have no mechanical connections 
between the ICE and the wheels. The ICE is turned off when the 
battery packs feed the system in urban driving. A significant 
amount of energy is supplied from the regenerative braking  
The series hybrid configuration is mostly used in heavy 
vehicles, military vehicles, and buses . An advantage of this 
topology is that the ICE can be turned off when the vehicle is 
driving in a zero-emission zone. Moreover, the ICE and the 
electric machine are not mechanically coupled;

         Regenerative  Controller
When the vehicle is running, the controller 
supplies the electrical energy from the battery 
to the motor. When the driver presses the 
brake pedal, the controller stops the electric 
energy supply to the motor and starts 
charging from generator to battery.

        Regenerative Braking System
A regenerative Braking System is a braking system that generates 
electrical energy during braking action. This generated energy is used 
for charging the battery, which is used again to rotate the motor (to 
run the vehicle).
Working principle:
This regenerative braking system works on the principle of 
‘conservation of energy’. The principle says that, the energy converts 
from one form to another form.
In friction braking system, the kinetic energy of the wheel is converted 
into the heat energy, which is lost to the atmosphere.
But in regenerative system, the kinetic energy of wheels is converted 
into the electrical energy.
This system is mostly used in electric or hybrid vehicles, which uses a 
motor to run the vehicle.
