Problems with electric motors at speeds above 150 km/h: what to do?

Problems with electric motors at speeds above 150 km/h are worrying electric car owners in Russia in 2025. Electric cars, such as the Rimac Nevera, can accelerate up to 412 km/h, but in Russian conditions, high speeds reveal malfunctions. The main difficulties are overheating, wear and tear and electronics failures. I will look at what drivers encounter and how to fix it, based on my experience.

Overheating: electric motors above 150 km/h

At speeds above 150 kilometres per hour, the electric motors are under high stress. The Rimac Nevera pilot noted that the cooling systems designed for forward motion are worse at extreme conditions [Web ID: 23]. The owner of Zeekr 001 from Novosibirsk complained: at 160 km/h the motor overheats after 10-15 minutes, especially in winter. Problems with electric motors at high speeds occur due to insufficient cooling and load on the battery.

Wear and tear on parts: the challenges of electric vehicle speed

High speeds accelerate wear. At speeds of 150-170 km/h, motor and transmission life is exponentially reduced due to air resistance [Web ID: 1]. In electric cars, such as the Tesla Model S Plaid, with three motors (over 1000 hp), the wear of bearings and windings becomes noticeable after 20-30 hours at maximum speed. In Russia, where the roads are worse, vibrations increase the problem. Tyres also wear out, which increases the risk of accidents.

Electronics: high speed electric motors

Electronics failures are a common problem. The owner of a Volkswagen ID.4 from Moscow reported multimedia hang-up at 155 km/h in freezing weather. User X mentioned a Moskvich 3e: the braking system triggers for no reason at high speeds. Controllers can overheat, causing the motor to shut down for 20-30 minutes [Web ID: 10]. Problems with electric motors at high speeds are often related to poor climate adaptation.

Solutions: electric motor faults 2025

1. Improve cooling: Install additional radiators or use a car with an improved system like the Rimac Nevera.
2. Limit your speed: For long-term use, keep your speed to 110-120 km/h as advised by experts [Web ID: 1].
3. Check the electronics: Regularly diagnose controllers and Hall sensors with a tester (24-60 V voltage) [Web ID: 10].
4. Choose adapted models: For Russia, Zeekr or Moskvich with a winter package will do.
5. Service: Contact a workshop to check windings and bearings after long journeys at speed.

Electric vehicle operation Russia: what to consider

For you, with car and yachting experience, reliability is important. High speeds in Russia make it difficult to operate because of the climate and roads. In 2025, the infrastructure for electric cars is still weak, with 10 cars per station. Before travelling, make sure there are chargers along the route and avoid long acceleration times above 150 km/h.

Conclusion: how to avoid problems

Problems with electric motors at speeds above 150 km/h are overheating, wear and tear and failures. Limit speed, improve cooling and check the electronics regularly. Choose models adapted to Russia and do a test drive on the track.
