Since the introduction of electric vehicles, the automobile world has not been the same. It has been a debate between the electrical and the mechanical or chemical engineers.
Transition to electric cars is gaining momentum and people are receiving the change well. Initially, it took over two decades to sell the first million electric vehicles, but now it takes only five months to sell the same number of cars. That is a major milestone for the EVs.
According to the recent government statistics, 26% of the total gas emissions come from the transport industry. The UK government has come up with an ambitious target to adopt up to 50% of Electric cars to be able to achieve the target of ultra-low emissions by 2030 and effectively zero emissions by 2040.
So why should people welcome the EVs?
The Electric Vehicles are Eco-Friendly
It has been a major concern to everyone about the climate changes and the effects it has on our environment. The introduction of the electric cars is part of the process of improving the climate as they do not emit any harmful gases that pollute the air. Luckily the cost and health related issues caused by air pollution will decrease.
The Engineers are also adopting renewable energy systems and it’s a great idea. You are able to charge your EV using the solar panel system on the go instead of waiting until you reach the grid. This method is more economical and saves time as you get to charge it during the day where most activities take place.
Some of the EVs engineers are taking recycling to the next level by using Eco-friendly materials to build the cars. For instance, the makers of Ford Focus Electric car are using recycled materials and padding the car with bio-materials.
Nissan Leaf is also adopting the recycling idea and it is impressive. The interior and exterior are partly made of recycled bottles, second-hand appliances, old car parts and plastic bags. They are all about recycling materials and environmental conservation.
The EV Saves You Money And Simpler To Service
The conventional petrol or diesel has starter motors, fuel injection systems, exhaust systems, radiators and other moving parts for it to function properly. This means the car needs constant lubing and oil changes among other maintenance activities. The whole process is a lot costly and tedious as it is a continuous process.
On the other hand, the EV only has mechanical parts. Which means the car doesn’t need an oil tank, transmission system or a catalyst converter. Less subsystem means simpler maintenance and cost-effective.
The battery technology is the major reason behind the electric vehicle concept. There are different types of electrification, the conventional hybrids, plug-in hybrids, mild hybrids and pure BEVs. The technology is leaning more on efficiency, energy density and weight of the batteries.
The most common battery type used in the EVs is Lithium-Ion and Lithium polymer battery. These batteries have a higher energy density than the weight they have. Rechargeable batteries, on the other hand, use a nickel-metal hybrid, lithium-polymer battery, lead-acid, Lithium-ion, NiCd and a less common zinc-air and molten-salt batteries.
The EV gets its power from charging through AC ports at households or different charging stations. The advantage of these methods is that almost every home has electricity and can easily power up the car. The battery charges via the installed grid but can also feed the energy back into the grid in case there is a need.
The EV drivers get to enjoy the convenience of charging at home and it is simplified by the charging EV App that enables you to initiate charging without having to walk into the garage.
Have More Powerful Motors And Are More Efficient
Depending on the battery capacity, the higher the current is produced the more powerful the motor is. The EV uses electromagnetic motors to deliver instant power to the drive train creating the torque that enables the EV to move forward. Due to the instant torque, no energy is wasted when accelerating.
Electric motors also work as electric generators, enabling the battery to recharge during braking. The rotor in motors consistently rotates when the braking system is activated. This causes the electrical field to reverse sending the electrons back to the battery. This process is known as regenerative braking.
Hence the EVs are able to recycle the energy unlike the internal combustion engine (ICE); the same energy is wasted in the form of heat from friction.
More EVs are adopting more sophisticated electronics and intelligent sensors as the heart of the car. The electric cars have advanced computerized technologies and come readily installed by design. The development of the automotive industry, however, has been a lot slower than other industries.
Thankfully, the automakers are up for the challenge and some of the smart cars won’t be available for another 7-8 years due to their advanced concept.
Different control units and wiring are installed to improve the user's experience by achieving more accurate and transparent systems that control your driving environment. The car is made smart enough to detect any faults and possibly prevent accidents.
Platforms like the mirror link technology, car play, and Android auto are adopted to help the driver adjust the content of the phone and are well displayed on the dashboard. The dashboard is fitted with larger screens with bigger buttons and icons that the driver can use easily without being distracted from the road.
Imagine being able to play your favorite music playlist, while you can receive important messages, or even get notifications on low battery pop-ups and suggestions of the next charging station along your way. Impressive!
*The range is the only disadvantage the EV has compared ICE cars. However, the electric cars are fast catching up and there are models like the Tesla that are performing really well. Higher capacity batteries are developed and soon the gap will be closed.
With the target of improving our environment, Electrical vehicles are the future and the government has implemented some policies favoring the EVs. Hopefully, the emissions will drop to 44% by 2030 as proposed by the government.
