Let's understand electric vehicle configurations based on electric drive train or electric motor drive.
There are several ways to connect with the will and on this will differentiate the different configuration
of electric vehicle that is possible for the four wheeler or see God.
The very basic arrangement, the conventional, we can say, is the direct conversion with the regular
Klutch gear and differential arrangement that is used with the base vehicle.
So this is old approach to use the regular car and converting the regular ICBC car to the electric vehicle
with all other arrangements remaining same and connecting the motor, replacing by the icy engine.
So in this case.
This is disconfirmation is used for the purpose when we want to convert the icy base vehicle to the
electric vehicle so it will have the benefit, we required minimum changes in the existing vehicle and
we only need to add the motor.
So in this configuration, bludge is used to connect to our connect or disconnect to our transmitted
from the motor to the will not get the gate is the mechanism.
We will have the several.
This is a gearbox.
So user has the ability to change the gear because I see busway engine cannot work without this because
at low speed hyper queequeg and high speed requirements, we need to adjust the speed torque ratio with
the gate so that with its engine we must require the safety arrangement.
But we will see later in case of electrical configuration, electric vehicle configuration, we can
eliminate the requirement of GEP.
But because this is the configuration used for the conversion purposes, we are using the same transmission
mechanism that is used for the vehicle and only replacing the icy engine with the motor.
So regimented depth and differential differential allows two ways to rotate at different speeds during
the journey.
So hope you all know about the differential.
What is the requirement of differential and why it is use?
If you don't know, I will share one link of one with you.
It will give you the very clear idea about the differential, but most people know about the differential
and its use.
So yeah, we need to understand this.
All additional requirement of clutch, gearbox and differential will add additional weight and cost
to the newly developed vehicle.
But because if we use for the northern purpose, then this is the best suitable configuration.
So differential because we got differential after two whales are connected in common chup then.
It will rotate always with the same speed, so the French will allow the tourists to rotate at different
speeds during the morning because during the turning in the radius, they never will.
And our power will hang the difference.
Right?
There is a tendency to sleep if we do not allow the.
Two bills to rotate at different speeds during the early, so this is the.
Rule of thumb differential, so it's also changed the direction of rotation from the linnear to the
danger.
So Differential Geary's the gearboxes, they're generally view the filing system with the reverse gear
clutch and electric motor.
So this arrangement is that convergent with clutch getting differential.
If we look at the size and weight, then this is the example of clutch plate of the car.
So consider the size and weight of this part, so later on, when we are eliminating this, you will
have no idea about the benefits of electric vehicle configuration.
This is the example of five gear is used for the car with the reverse, so you need to consider the
size weight as well as cost of this park.
So it is the.
When we use the gate system.
If we had a differential differential, also having the significant weight cost as well as differential,
also create the restriction in the ground clearance of the vehicle because the differential in the part
was having the lowest ground clearance for the vehicle.
So that aspect we need to consider when we.
Understand the different configuration of electric vehicle.
Let's see the next configuration with the fixed gear differential.
So we already discussed and compared the four characteristic of CNG engine, and that's quite characteristic
of electric motor.
So yet we do not require the gate system and.
We can use the fix gate arrangement with the motor so that there is elimination of the clutch and get
a box so size and weight to fix get is reduced with compared to gearbox that is required to change from
the one to five and reverse the diesel requirement will be eliminated.
Why the fix gate is required as we already.
Discussed or not, but in case of motor, the generally designed for the high speed and to meet the
maximum speed requirement of the will be required to fix gate arrangement so higher with the fixed get.
We also discussed Mitrokhin produced a sufficient torque during the starting as well as during the maximum
speed.
So fixed yet is having a benefit to it compared to get changing arrangement and still we are raising
the differential in this configuration.
This is the most widely used configuration called the single integrated arrangement in this case to
fix git and differential arrangement in into one unit in the one assembly.
It is called the Single Integrated Arrangement.
So now it is modern electric vehicle used to build vehicle.
They are not converging, but more to the purpose built vehicle.
So we built a purposefully for electric vehicles and we are discussing about the fully electric vehicle
as of now.
So on the single assembly will have the mortar unit again and the differential, it will reduce the
size and weight it compared to previous arrangement.
You read the example of this type of configuration demonstrated by the electric vehicle in the Auto
Expo 2020 held at Noida, so you can see this complete unit becomes smaller and compact and this used
nowadays more widely in the modern electric car.
So up to now in this country configuration that Olá, the single motor drive.
Now, next configuration is the direct drive with that differential.
So you can see we can eliminate the requirement of differential to weight and size of the friction with
the benefit.
It will not be there.
So it is dual motor configuration.
We need to the to motor.
Now, if you consider the cost, generally we require the motor with the half power each.
The total power can be considered as the summation of the modern power will be total power required.
So motor cost will not increase as much as you're thinking.
So it is how Ford Motor with compared to previous configuration and it is attaching both the will to
now both wheels are separately and free to move at different speeds.
So differential is not required.
But we require the electronic control.
Who can set the electronic differential arrangement in this configuration?
We are in the motor with the fixed jet which is attached to the wheel, so it will have the motor and
fixed get set.
So this motors is not have motor and if we consider the configuration, we are going to use the hub
motor also in the two or dual motor configuration.
If you consider this configuration, this mortar attack in the will and mortar, the form of mortar
with the fixed get systems is generally litigation type arrangement is there in hub mortar when we say
the hub mortar with the fixed gear arrangement.
So it will drive with the explanatory arrangements, the dual mortar configuration.
So we will also have the four mortar configuration saying this is the dual mortar configuration in will
drive.
Now, we can also design the mortar like the DCP and Saddam or the special mortar, the hybrid mortar,
which can eliminate the requirement of get if anyone is an electrical engineer, they will know that
they're designing the high speed mortar, which somehow benefited in terms of our weight ratio.
So generally, we prefer designing mortar and the high speed and using the fixed kit.
But now with the ability and SRM and the hybrid combination, we are now able to design the mortar with
the low speed, also eliminating the requirement of even planetary grid arrangement.
So this is the latest configuration that we can use in less drive.
The dual motor configuration.
Can we use?
So as of now, we have discussed the six configuration plus three, that the single last three are the
dual configuration.
What you need to do.
We'll discuss the several things benefits you need to go through the thought process, and before you
go to the next session, just try to knock down the fight of comparison amongst convergent TV and purpose-built
electric vehicle system.
So compare this to and not on The View, but we are going to discuss in the next section, but before
that, you apply your mind and then we will see what are the part, you know, not enough and what are
the people discussing the next session.
So what if we had the convergence of what are the benefits and drawbacks and what are the benefits of
the purpose built electric vehicle system?
You also need to compare the single mother dress with the girl, Martha.
So what are the pluses and minuses of a single murder trial and the type that we are going to discuss
in the next station?
