Energy Guide: Electric Cars

Written by: Omar Zaifulizan

Cars are vehicles that let us go from place to place in an efficient manner. The technology for switching from a gas to electric car is already here, and you need to know which one is right for you!

In today’s day and age, electric cars (also known as EVs) come in many shapes and sizes, with different brands such as Toyota, Nissan, Honda, Chevrolet, BMW, Kia, the infamous Tesla, as well as many more! When purchasing an electric car, you will be able to save money and as well help the environment. Electric vehicles produce less pollution so that means they reduce harmful air pollution from exhaust emissions. Electric cars can also use renewable energy to charge. With this, greenhouse gas emissions will be reduced even further.

When purchasing an electric car, there are three types: hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV), and battery electric vehicles (BEV).

HEVs are powered by both petrol and electricity. The electric energy is generated by the car’s own braking system to recharge the battery. This is called regenerative braking, a process where the electric motor helps to slow the vehicle and uses some of the energy normally converted to heat by the brakes.

PHEVs are also powered by both petrol and electricity. PHEVs can recharge the battery through both regenerative braking and plugging in to an external electrical charging outlet. In PHEVs the petrol engine extends the range of the car by also recharging the battery as it gets low. PHEVs have an electric motor range of between 31-62 miles before the petrol engine kicks in. Due to the added weight and complexity, the electric motor range of a PHEV will generally be less than a BEV.

BEVs are fully electric vehicles, which means they are only powered by electricity and do not have a petrol engine, fuel tank or exhaust pipe. Keep in mind you still have to charge it with an external electrical charging outlet to charge the battery. The range of a BEV is currently around 62-105 miles, and as most motorists drive around 21-43 miles per day, the BEV can be a good option.

With all this knowledge I hope you know which electric vehicle is right for you!
