Technology continues to advance and it has also evolved in the automobile industry. There has been advancement of technological features in most if not all vehicles and the system keeps on getting better.
One of the most substantial breakthroughs is the creation of electric vehicles and an abundance of people have already embraced EV technology.
EVs have an electric motor instead of the usual Internal Combustion Engine.
Types of EVs
There are a few variants in the EV categories. Some run entirely on electricity while others are hybrid i.e run on both fuel(petrol /diesel) and electricity.
- Plug-in electric. Gets all it’s power when plugged in a charge and runs entirely on electricity.
- Plug-in hybrid.Mostly uses electric power and can run on fuel when electricity is depleted.
- Hybrid -electric. Mainly runs on fuel. It’s electric battery is recharged through regenerative breaking and you can switch from using fuel engine to EV mode or vice-versa at the touch of a button.
The main advantage of EVs is that they do not exude any exhaust hence maintain a clean atmosphere.
Components in an Electric Vehicle
In as much as EVs are more advanced and complex compared to cars with Internal Combustion Engine, EVs have fewer moving parts. They are likewise satisfying to drive and feel lighter than the typical car.
- Battery (auxiliary battery). Stores energy to run the EV. The higher the kW of the battery the higher the distance it can travel.
- Electric Traction Motor. Drives the vehicles wheels. Some EVs have motor generators that deliver both drive and regeneration functions.
- Transmission (electric). Transfers mechanical power from the Electric Traction Motor to the wheels.
- DC/ DC converter. Converts a high rate DC to a lower rate DC when charging the car.
- Charge port. Connected to an external power source so as to charge the battery pack.
- Traction Battery Pack. Stores electricity for use by the electric traction motor.
- Thermal system. Maintains a proper range of operating temperature for the electric motor, engine and other components.
- Power Electronic Controller. Regulates the flow of electrical power delivered by the traction battery. This ensures that the speed of the electric traction motor and torque created are on check.
- Onboard charger. Takes the incoming Alternating Current provided via the charge port and converts it to Direct Current to charge the traction battery. Additionally, it communicates with the charging apparatus and monitor’s the battery’s current, voltage, temperature and state as it charges.
- Inverter. In rather very few circumstances, you might find that an EV uses AC instead of DC. The inverter converts DC to AC so as to make the current compatible with the vehicle.
Varied EV models differ in reliability ranging from the manufacturer. Averagely, most EVs can go for a couple of hours on a single charge.
Recently, there has been massive advancement on the EV technology and the cars are spreading worldwide. Several charging stations are also being set up on various locations as the sales margin increase.
