This device converts high-voltage DC power from the traction battery pack to the low-voltage DC power needed to power the car accessories and recharges the additional battery.
This motor uses energy from the traction battery group, and it drives the wheels of the car. Some vehicles use engine generators that perform both driving and refurbishment functions.
It absorbs the obtained AC electricity through the charging port and converts it to DC power for charging the traction battery. It tracks the characteristics of batteries such as voltage, current, temperature, and charging status when charging the packet.
Control using energy electronics
This unit manages the flow of electrical energy provided by the traction battery and controls the speed of the electric traction motor and the torque it produces.
This system maintains an appropriate operating temperature range for the motor, electric motor, power electronics, and other components.
Traction battery pack
stores electricity for use by the electric traction motor.
The transmission transmits mechanical energy from the traction motor electrode for driving wheels.
#2. Hybrid Cars
A hybrid vehicle is a vehicle that uses at least two different energy sources to move. Generally, a hybrid car is a car that uses fuel and electricity to move by means of two engines: one thermal, the other electric.
From a certain point of view, hydrogen cars can be considered as hybrid vehicles. They use the hydrogen from their fuel cells as a source of chemical energy to power a battery and an electric motor.
Hybrid car vs plug-in hybrid: what differences?
A hybrid vehicle combines an internal combustion engine, petrol or Diesel, with one or more electrical blocks, located on the front axle and/or on the rear axle. It can be rechargeable or non-rechargeable, the two categories differing on many points (technology, price, use, sales volume).
The electric range of a non-rechargeable hybrid car is limited to a few kilometers of city driving. With a low capacity, around 1 kWh, its battery is generally recharged thanks to the heat engine and a device for recovering kinetic energy when braking.
Conversely, the larger battery capacity of a plug-in hybrid car, around 10 kWh, gives it a range often between 20 and 60 km and a top speed of around 120 km / h. It is only when these values are exceeded that the internal combustion engine takes over, knowing that charging is similar to that of an electric car, through a household outlet or a charging station.
Environmental benefits of hybrid cars
Hybrid cars, in particular plug-in hybrids, therefore have the particularity of taking advantage of the autonomy and fuel distribution network of conventional cars while emitting less CO2 and pollutants or even dispensing with fuel occasionally.
Engine hybridization is therefore part of the solution to the transition to clean vehicles that are independent of fossil fuels.
#3. Fuel Cell cars
Hydrogen fuel cell cars are powered by an electric motor and are therefore classified as e-cars. The common abbreviation is FCEV, short for “Fuel Cell Electric Vehicle,” in contrast to a BEV or “Battery Electric Vehicle.”
There is one crucial difference between hydrogen fuel cell cars and other electric vehicles – hydrogen cars produce the electricity themselves. So, unlike in fully electric or plug-in hybrid vehicles, the vehicle doesn’t get its power from a built-in battery that can be charged from an external power source. Instead, hydrogen cars effectively have their own efficient power plant onboard: the fuel cell.

Advantages of Fuel cell cars
Alternative propulsion systems are planned to minimize pollutant emissions, especially climate-harming CO2, but also other noxious gases like nitrous oxide. A hydrogen fuel exhaust gas consists of pure water vapor. Therefore, hydrogen fuel cell technology is emission-free locally, which means keeping the air clean in cities
Production of hydrogen requires electric energy. This electrical energy is used by the electrolysis cycle to break down water into its constituent elements, hydrogen, and oxygen. If the electricity used comes from renewable energy sources, there is a neutral carbon footprint to hydrogen production.
In comparison, if fossil fuels are used, this would potentially have a knock-on impact on the fuel cell cars’ carbon footprint using hydrogen. How big the effect is depending on the mix of energy used. Hydrogen-fuel cell cars are no different than other hybrid vehicles in this regard.
One Challenge; Producing hydrogen
Hydrogen production means losses during electrolysis. Therefore the total output in the energy chain “power to vehicle drive” is just half the amount of a BEV. Hydrogen can be emitted at times when electricity from renewable sources is over-supplied when the wind or solar energy currently generated is not otherwise used. The scope for that is immense.
