Welcome to the vision energy source for the electric vehicle in this session will discuss about the
various energy sources that can be possible to drive the electric motor as we have different electric
vehicles are the device that the electrical motor as a propulsion.
So let's discuss what are the different alternatives other than the battery that can be used as an energy
source?
Whenever we think about energy, source or things come to mind is always battery.
That is no doubt electric batteries are used as a main source for the electric vehicle, but there are
possibilities of using someone at the source as a main source as well as some additional source can
be also used to enhance the battery range.
So we'll discuss about the various energy source.
We start with the battery at the DC source that controls the DC motors, as well as the AC motor with
the additional power electronics controller.
More tremors, electric battery taps are the lead acid and lithium ion batteries.
So nowadays we are using the lithium ion batteries or the electric propulsion and electric vehicle that
we call the metal electric.
We also option to use hydrogen fuel cell as a source of electrical energy to be used with the motor
driven vehicle or vehicle which is propelled by the electric motor.
We will discuss in detail about this energy source later.
We can also help the ultra capacitor that can be used as energy source for the electric vehicle.
And we can also use, in addition, the flywheel as a source of electric energy.
But on the Electric Motor will also discuss about how it's working in Detroit and its limitation and
how we can extend the range of battery using the energy source.
So it's called the hybridization of sorts, which is the latest trend in electric vehicle technology
to use more than one energy source in addition to battery and to support the battery.
And we can have the fuel cell ultra capacitor flywheel that can be used to extend the range of battery
and with the proper optimization of its use.
So before starting each energy source, let's first discuss the parameters and the ways that we already
know about the parameters of the energy source.
We know the energy source is represented in the most specific energy.
Yet we are not comparing the battery with the gasoline fuel because specific energy battery is very
lightweight compared to petrol and diesel under the efficiency of electric motors is very high contrast.
But we are going to discuss the energy source and compare it so we can have a better idea of hybridization
and how we can improve the hybridization of energy source to extend the range of electric vehicle specific
energy, energy density and power density at three main parameters of energy source that we need to
understand specific energies, energy per unit mass.
That means it's measuring what that what gayety.
It can also be measured in July, but Kaiji one, what section is equal to one July that we know?
I'm using the unit waterwork energy density is the energy per unit volume, I it's always not necessary.
It's same because we'll discuss it.
But in case of seeing also in case of hydrogen also, that is the difference between what are cagey
and what are what liter.
And so energy density is energy per unit volume, methane water per liter.
This is the general unit we use.
And as a unit, as you know, water meter cube.
So what are the better way to understand and having the idea about its energy density?
Our density is the power per unit volume work, but little.
So these three parameters must be understood and based on this parameter will compare to different energy
source also and before comparison is tacked on the battery and we will understand the different energy
source entity and then we will discuss about the hybridization of energy source.
