2. The 1st human carrying EV with its own power source was
tested along a Paris street in April 1881 by French
inventor Gustave Trouve.
In 1880 Trouve improved the efficiency of a small electric
motor developed by Siemens and using the recently
developed rechargeable battery, fitted it to an
English James Straley tricycle, so inventing the world’s
This EV was successfully tested on 19 April 1881 along
the Rue Valois in central Paris but he was unable to
3. Later on 26th May 1881, the 5 metre Trouve boat
prototype, called Le Telephone reached a speed of
3.6 km/h (2.2mph) going upstream and 9.0 km/h
(5.6 mph) downstream.
Although in 1859, with the invention of the lead-acid
battery by French physicist Gaston Plante and Camile
Alphonse Faure, another French scientist, significantly
improved the design of the battery in 1881.
The 1881 improvements in battery design greatly
increased the capacity of such batteries and led directly
to their manufacture on an industrial scale.
4. A Vehicle that runs on electricity stored in
batteries and has an electric motor rather than an
internal combustion engine as in conventional vehicle
is called BEV.
BEVs use 100% electricity as source of energy.
5. EVs with only batteries to provide power to the drive train are
known as BEVs.
BEVs have to rely solely on the energy stored in their battery
packs therefore the range of such vehicles depends directly on the
Typically they can cover 100–250km on one charge, whereas the
top-tier models can go a lot further, from 300-500km.
These ranges depend on driving condition and style, vehicle
configurations, road conditions, climate, battery type and age.
Once battery pack depleted, charging takes quite a lot of time
compared to refueling a conventional ICE vehicle.
It can take as long as 36Hours completely replenish the batteries
there are far less time consuming ones as well, but none is
comparable to the little time required to refill fuel tank.
Charging time depends on the charger configuration, its
infrastructure and operating power level.

9. The BEVs are further classified into four categories
on the basis energy storage sources;
FCEV: [FC+ Battery]
UCEV: [UC+ Battery]
UFEV: [UF+ Battery]
Note: PEV are most commonly known as BEVs.
10. PEV: Pure Electric Vehicles or Battery Electric Vehicle
are those EVs in which 100% vehicle propulsion is
developed through battery. In this type of EV, the battery
is used as sole energy source .
FCEV: The Fuel Cell Electric Vehicle are those EVs in
which the vehicle/electric propulsion is developed as
combination of energy stored in fuel cell and battery. The
battery used in this type of EV is a hybrid energy source.
In FCEV, battery is primarily used for absorbing the
regenerative power because the fuel cell is incapable of
storing the regenerative energy during braking mode of
11. UCEV: The Ultra-Capacitors Electric Vehicle are those
EVs in which vehicle propulsion is developed as
combination of energy stored in ultra-capacitor and
battery. Again the battery used in type of EV is a hybrid
energy source. Although in UCFV based EVs, batteries
are required for storing energy because ultra-capacitor
have very low specific energy and they are unable to
store the regenerative energy.
UFEV: The Ultra- Flywheel Electric Vehicle are those
EVs which vehicle propulsion is developed as
combination of energy stored in ultra-flywheel and
battery. The battery used in this type of EV as a hybrid
source of energy similar to UCEV. In UFEV, batteries
are required for storing energy because ultra-flywheel
also have very low specific energy.
