Meanwhile, maintenance costs are kept lower as the engines are simpler and help brake the car, which saves drivers from an over-reliance on brake pads.
There are four main types of electric cars:
- Plug-in hybrids
- Electric vehicles
- Fuel cell electric vehicles
So how do electric cars work, and what are the main differences between them?
Hybrids are vehicles that combine a petrol-fuelled internal combustion engine and a battery-powered electric motor to power a can that can perform, while being both affordable and sustainable.
The Hyundai IONIQ Hybrid is designed to be compact and highly efficient. Its chassis combines 53% Advanced High Strength Steel which combines cleverly with lightweight aluminium hood, tailgate and suspension components, saving 45%, or 12.6kg, of weight.
Meanwhile, the IONIQ Hybrid’s 1.6-litre Kappa GDi engine combines with a permanent magnetic electric motor to deliver maximum outputs of 105 PS and 43.5 PS respectively. This enables vehicle to operate in pure electric mode at speeds up to 120 km/h.
2. Plug-in hybrids
Plug-in hybrids also combine a petrol-fuelled internal combustion engine with a battery-powered electric motor. However, these vehicles are charged when plugged into a special power station. Although they have a limited range when operated in electric mode, the can be switched to traditional fuel power when the electric motor is unable to provide power.
3. Electric vehicles
Electric vehicles are operated entirely with an electric battery and do not have an internal combustion engine. This means they don’t have an alternative fuel source to switch to if they run out of power, which ensures no carbon dioxide is released.
In order to recharge the battery, electric cars must be plugged into an external power source. However, they can also draw power from the braking system, as regenerative braking coverts a vehicle’s kinetic energy into a form that can be stored until needed.
The All-New Kona Electric recently became Hyundai’s second EV and combines an SUV body type with eco-mobility. It features the option of two different powertrains, including a long-range battery version which provides a driving range of 482 kilometres.
4. Fuel cell electric vehicles
The fourth kind of electric car is fuel cell electric vehicles (FCEVs). FCEVs are powered by an electric motor which is charged-up by combining hydrogen and oxygen to create a chemical reaction.
There are three main components in a fuel cell. The Proton Exchange membrane lets protons pass through but not electrons. The anode and cathode are defined by the flow of current, which allows electrons to flow in and out.
Hyundai Motor was the first car manufacturer to mass-produce FCEVs with the ix35 Fuel Cell. Earlier this year, the company unveiled the All-New NEXO, which combines the practicality of an SUV with clean, advanced fuel cell know-how.
