Electrifying the Truth: Unveiling the 8 Common Myths About Electric Car Mechanics

Electric cars generate a lot of attention and interest, but they are also surrounded by numerous misconceptions. In this article, we’ll debunk eight common myths about the mechanics of electric cars to help you separate fact from fiction.

1. Electric Cars Don’t Need Maintenance

Myth: Electric cars, being without a combustion engine, require no maintenance.
Reality: Although electric cars require less maintenance than combustion engine cars, they still need regular care such as brake checks, tire inspections, fluid checks, and cooling system maintenance for the battery. It’s important to note that everything that cools the battery should not be taken for granted, and a certified Plug-in garage will ensure your coolant levels are checked during your visit.

2. Batteries Need Frequent Replacement

Myth: The lifespan of an electric car battery is very short and expensive to replace.
Reality: Modern electric car batteries are designed to last for many years, some even up to the full lifetime of the vehicle. Many are guaranteed by the manufacturer for a period of up to 8 to 10 years. It is crucial to check the user guide to maximize the battery’s potential.

3. Full Charges Are Good for the Battery

Myth: Fully charging the battery will keep it healthy.
Reality: Answers may vary depending on the type of battery your car uses. Refer to the user guide provided with your car to understand the specific battery type and charging guidelines. It’s not because a Tesla Model Y has certain guidelines that a Tesla Model 3 will have the same.

4. Electric Cars Don’t Perform Well in the Cold

Myth: Electric car batteries lose a lot of capacity in the cold.
Reality: Although battery performance can be slightly reduced in very cold conditions, measures such as battery preheating can help minimize this effect.

5. The Braking Systems are the Same as Combustion Cars

Myth: The braking system of an electric car doesn’t need maintenance as it’s identical to combustion engine cars.
Reality: Electric cars often use a regenerative braking system, but with the same brakes that may have specific maintenance needs. Discs will rust instead of wearing out, and caliper components can seize.

6. Electric Cars are Not Truly “Green” Because of Their Batteries

Myth: The production and recycling of batteries make electric cars as polluting as combustion engine cars.
Reality: While battery production does have an environmental impact, the overall lifecycle of an electric car is generally less polluting than that of a combustion engine car. As car innovation advances, so does the battery and its recycling industry to become more eco-friendly.

7. All Chargers are Compatible

Myth: All charging stations are compatible with all electric cars.
Reality: There are different types and levels of chargers, and although many connectors are standardized, not all are compatible with every vehicle. One of our articles states that recent updates of iOS 17 and Android will provide necessary options to find chargers compatible only with the user’s vehicle.

8. Electric Cars are Completely Silent

Myth: Electric cars are completely silent, making them dangerous for pedestrians.
Reality: Many electric cars emit artificial sounds at low speeds to alert pedestrians of their approach. Software extensions can be installed or activated depending on the brand and model to mimic the sound of a gasoline car, adding an extra thrill for the driver.


It’s crucial to separate myth from reality when it comes to the mechanics of electric cars. Misunderstandings and misconceptions can easily accumulate, especially in a rapidly evolving field like this one. Fortunately, as technology advances and knowledge spreads, myths are gradually being dismantled.
