Today transportation sector has facing many problems with conventional vehicles like petroleum and diesel vehicles which release most of the pollutants like CO2 and nitrogen oxide emissions which ultimately have an effect on human health. so to decrease this problem there is the invention of electrical vehicles but to fixed battery EVS the owner of the vehicle should wait for long hours to charge one vehicle and if the vehicle stops in any remote areas then it is difficult to charge the battery. So to reduce this problem and to increase electrical vehicle using the solution is to use autonomous battery swapping stations and producing mobile van technology for charging the vehicle in remote areas this idea ultimately increases EV adoption in the world which leads to having good human health.

3. ABSTRACT
Today transportation sector has facing many problems with
conventional vehicles like petroleum and diesel vehicles which releases most
of the pollutants like CO2 and nitrogen oxide emissions which ultimately have
effect on human health.so to decrease this problem there is invention of
electrical vehicles but to fixed battery EVS the owner of the vehicle should wait
for long hours to charge one vehicle and if the vehicle stops in any remote
areas then it is difficult to charge the battery. So to reduce this problem and to
increase electrical vehicle usage the solution is to use autonomous battery
swapping stations and producing mobile van technology for charging the
vehicle in remote areas this idea ultimately increase EV adoption in the world
which leads to have good human health.

4. Introduction to Electric Vehicle
 An electric car is an automobile that is propelled by one or more
electric motors, using energy stored in rechargeable batteries.
 The first practical electric cars were produced in the 1880s. Electric
cars were popular in the late 19th century and early 20th century,
until advances in Internal combustion engines.
PRIMARY COMPONENTS OF AN ELECTRIC CAR:
I. Battery
II. Motor Controller
III. Electric Engine

5. Charging of Electric Vehicle
The batteries are charged using grid electricity either from wall socket
or a charging point.
Types of Charging:
1. Trickle charge
2. AC charge
3. DC fast charge
Challenges in Charging:
• More charging time
• Battery degradation due to fast charging
• Does not have grid reliability to support the load.
• Numbers of stations are limited.

6. Different Cars have Different Battery:
Every electric car manufacturer have their own concepts on
building batteries and where these batteries place in the car
 So due to different batteries production should be with high level of
security(short circuits) and stations at different places.
War of standards:
If there was a single standard battery the
people easily find station
Manufacturers would collectively benefit to sell more vehicles.

7. Specifications of the Vehicle
Body style 6-door hatchback
Electric motor 47 kw(63 hp) ,180 N-m
permanent magnet motor
Transmission Single speed reduction
gear
Battery 16 kwh(Li-ion)
Range 120-130 km
Dimensions 3.0*1.8*1.4 m

8. Modelling of Swapping Mechanism
The design of battery swapping based on mistubishi car
The design is done for two batteries in the same car.
PARTS MODELLED:
1. Chassis
2. Base plate
3. Conveyor
4. Batteries
5. Pneumatic gripper
6. Battery Compartment
7. Permanent magnet motor
8. Electrical Linear Actuator

9. Catia Model

11. Analysis of Chassis
The most important one in the car is chassis which bear all
the loads in the car doing load analysis for chassis is the
most suitable one.
The analysis done is Static analysis.
Materials used for analysis:
1. Structural steel
2. Aluminum alloy

12. Analysis for Structural steel:
Total

14. Additive Manufacturing for chassis
Additive manufacturing, also known as 3D printing, is a transformative
approach to industrial production that enables the creation of lighter,
stronger parts and systems.
 Chassis done using fused deposition modelling.
To print chassis the material used is PLA.

15. Mobile App
Mobile apps is software application which is used by every smartphone
user.
 “BANDY” app is used for communication between station
,driver and battery

16. Companies Using The Battery Swapping

17. Conclusion
By using conventional electric vehicles with fixed battery it
have so many challenges like range anxiety, driver has to wait for hours
of time in the charging station which causes him as work delay .By
introducing electrical vehicle battery swapping technology in the world
makes to have negligible pollutants in air, there is no time delay and with
the use of app which created by using advanced technology like iot gives
suggestion to car owner every time and make his life better without any
stress.

18. Future Scope
Smart charging of electrical vehicles in swapping station.
Creating mobile van battery swapping for remote areas people.
Building a good business model which is advantageous to driver and
station company.
Automated scheduling and billing system for battery sharing network.
Forecasting of storage availability in battery sharing station and gives
message to user.
