Today, the concept of an EV is expanding rapidly. I remember in 2012, there were only about 60 of them on the road in Canada, but that number is increasing rapidly today. By 2020, around 300,000 EVs will be on the road here. These are impressive numbers. But I believe that EVs and HEVs are similar devices with a few differences. These differences in their design, operation, or both are what help us decide between them.
The differences are shown below.
Design of an EV:
Both EVs and HEVs utilize battery-powered engines to produce power. (They are a hybrid depending on the type of vehicle) Electric cars are virtual “100% battery-driven.”
They are much larger than HEVs but are not far from the largest. (Note that the difference is that HEVs are not as large.) They require less maintenance.
An electric car has a greater power density than a HEV, which is referred to as the electric-to-cell factor.
HEVs with higher power density are easier to the plugin.
“GSI,” which means “greater surface area,” is an important factor when choosing an HEV.
An electric car battery is made from a variety of materials that have different materials.
An HEV battery is made of rechargeable NiMH cells, whereas an EV battery is made up of NiHMH cells.
An electric car battery is larger and heavier than a HEV battery.
In addition, an electric car battery can have disadvantages: the car is “slippery” at impact, has lower visibility, a higher maintenance cost, and the cost of its maintenance is higher.
Since there are two methods of gaining an electric car battery, it is better to be guided by its advantages and disadvantages. In comparison, the technology for HEVs is both similar to EVs and different as it relies on the technology used in batteries for hybrid vehicles.
The lifetime of a HEV battery depends on its power rating.
Most HEVs sell for about $20,000—$30,000.
An EV battery is two-tier. If you have an EV with a high life (fill a lifetime of 300,000 miles), you would consider buying an EV more expensive than a HEV. An EV battery is made up of “nano-cell modules”. For example, the batteries in the Samsung Galaxy S6 have 100 cells and, when recharged, they have even more charge in them (151 cells). You can also re-use an EV battery as the same should be the same for a HEV.
The size of an EV battery and its mechanical structure are among the most important factors when buying an EV battery.
An EV battery has a “thermal barrier”.
An HEV battery has a thermodynamic barrier. An internal combustion engine is electric in nature and is why an HEV car is more efficient than an EV.
Unlike an HEV, an EV battery has liquid-lubrication, which is important as it would allow the battery to last longer. In addition, an EV battery has easy access by the vehicle’s staff to repair it. Most HEVs do not have easy access by maintenance staff to charge the battery.
