Introduction
• It canbe powered by a collector system, with
electricity from extravehicular sources, or it can be
powered autonomously by a battery (sometimes
charged by solar panels, or by converting fuel to
electricity using fuel cells or a generator).
• EVs include, but are not limited to, road and rail
vehicles, surface and underwater vessels, electric
aircraft and electric spacecraft.

Types of ElectricVehicles
Battery Electric Vehicles (BEV)
• Compared to an internal combustion
engine, battery powered electric vehicles
have approximately 99% fewer moving
parts that need maintenance.
• Creates very little noise
• No exhaust, spark plugs, clutch or gears
• Doesn't burn fossil fuels, instead uses
rechargeable batteries

Types of ElectricVehicles
• BEVs can be charged at home overnight,
providing enough range for average journeys.
However, longer journeys or those that require
a lot of hill climbs may mean that the fuel cells
require charging before you reach your
destination, although regenerative braking or
driving downhill can help mitigate against this
by charging the battery packs.

Types of ElectricVehicles
• The typical charging time for an electric car
can range from 30 minutes and up to more
than 12 hours. This all depends on the
speed of the charging station and the size of
the battery.
• In the real world, range is one of the biggest
concerns for electric vehicles, but is
something that is being addressed by
industry.

Types of ElectricVehicles
Plug-in Hybrid Electric Vehicles (PHEV)
• Rather than relying solely on an electric motor,
hybrid electric vehicles offer a mixture of
battery and petrol (or diesel) power.
• This makes them better for travelling long
distances as you can switch to traditional fuels
rather than having to find charge points to top
up the battery.

Types of ElectricVehicles
• Of course, the same disadvantages that
apply to combustion engine vehicles also
apply to PHEVs, such as the need for more
maintenance, engine noise, emissions and
the cost of petrol.
• PHEVs also have smaller battery packs,
which means a reduced range.

Benefits of ElectricVehicles
Lower running costs
• The running cost of an electric vehicle is
much lower than an equivalent petrol or
diesel vehicle.
• Electric vehicles use electricity to charge
their batteries instead of using fossil fuels
like petrol or diesel.

Benefits of ElectricVehicles
Low maintenance cost
• Electric vehicles have very low maintenance
costs because they don’t have as many
moving parts as an internal combustion
vehicle.
• The servicing requirements for electric
vehicles are lesser than the conventional
petrol or diesel vehicles.

1) 100% interest free loans would be made
available to State Government employees for
purchase of Electric Vehicles.

Benefits of ElectricVehicles
No noise pollution
• Electric vehicles have the silent
functioning capability as there is no engine
under the hood. No engine means no
noise.
• The electric motor functions so silently
that you need to peek into your
instrument panel to check if it is ON.

The purpose of epidemiology in public health practice is to
discover the agent, host, and environmental factors that affect health;
determine the relative importance of causes of illness, disability, and death;
identify those segments of the population that have the greatest risk from specific causes of ill health; and
evaluate the effectiveness of health programs and services in improving population health.
