Are electric cars breaking down? What kind of repairs do they need?

26.05.2022 /

On discussion forums, the question about the failure rate of electric cars appears more and more often - do they break down? Do electric cars need to be repaired? Is it worth buying an electric car to save money on the service? Here is an article prepared on the basis of the statements of the owners.

  • Do electric cars break down
    • What can break in an electric car

YES. Like any appliance, an electric car can also break down.

NOPE. From the point of view of the owner of a combustion car, electric cars practically do not break down. They have no tie rods, oil pans, sparks, silencers. Nothing explodes there, it doesn't burn, it doesn't get red hot, so it's hard to find extreme conditions.

Electric cars are powered by a simple electric motor (invented in the XNUMXth century, basically unchanged to this day) with high efficiency, which specialists say that it can travel 10 million (!) kilometers without failure (see the statement of the professor from the polytechnic university):

What can break in an electric car

The honest answer is virtually anything. After all, this device is like any other.

However, thanks to working in less extreme conditions and 6 times fewer parts, there is really little that can go wrong in an electric car.

> Which electric car is worth buying?

Here are the parts that sometimes fail and need to be replaced:

  • brake pads - due to regenerative braking they wear 10 times slower, replacement not earlier than after about 200-300 thousand kilometers,
  • gear oil - according to the manufacturer's instructions (usually every 80-160 thousand kilometers),
  • washer fluid - at the same rate as in a combustion car,
  • bulbs - at the same rate as in a combustion car,
  • batteries - they should not lose more than 1 percent of their capacity for each year of driving,
  • an electric motor - roughly 200-1 times less (!) than an internal combustion engine (see note on oil, couplings and extreme conditions of explosive combustion).

There is also a recommendation for battery coolant in the manuals for some electric cars. It is recommended to inspect and replace it after 4-10 years from the date of purchase, depending on the brand. But that's the end of the recommendations.

Therefore, in the case of an electric car, compared to an internal combustion car, the annual savings on services are at least PLN 800-2 in Polish conditions.
