The UK’s Ministry of Transport (MOT) requires vehicles over 3 years old to undergo a safety and environmental test every year. The MOT test has been modified to account for changes in the automotive industry, particularly the swift uptake of electric cars (EVs). 

In order to make sure EVs are dependable and safe for usage on public roads, the 2024 MOT regulation modifications include additional inspections and requirements tailored for EVs. Here, we examine the main modifications and how they may affect UK residents who own electric vehicles.

Its an essential step to run a free MOT history check before buying any used vehicle.

Enhanced battery and charging system

Battery condition

One of the most critical components of an electric vehicle is its battery. The 2024 MOT changes introduce a thorough inspection of the battery’s physical condition. Technicians will look for any signs of damage, corrosion, or excessive wear. This is crucial as the battery is not only a significant investment but also central to the vehicle’s operation. Damage or degradation can lead to performance issues and potential safety hazards.

Charging port

The charging port is another focal point of the new MOT rules. Inspectors will check that the port is secure, free from damage, and functioning correctly. Any issues with the charging port, such as loose connections or visible wear, can result in a failed MOT test. This change ensures that EVs can be charged safely and efficiently, preventing potential electrical hazards.

High voltage cabling

High voltage cabling, which connects the battery to various components of the vehicle, will also undergo inspection. Inspectors will check for signs of damage, improper repairs, or wear that could compromise safety. This change highlights the importance of maintaining the integrity of the EV’s electrical system to prevent accidents or malfunctions.

Updates to emissions testing

Emissions free verification

While electric vehicles do not produce tailpipe emissions, the MOT test now includes verification that the vehicle is indeed emissions-free. This involves checking the vehicle’s onboard diagnostics to confirm that the electric drivetrain is operating correctly and there are no unauthorized modifications that could affect its emissions status.

Hybrid vehicles

For hybrid vehicles, the 2024 MOT changes introduce a more detailed emissions test. Inspectors will test both the electric and combustion engine components to ensure they meet the required standards. This dual approach ensures that hybrid vehicles are environmentally friendly and perform efficiently across both power sources.

Brake system checks

Regenerative braking

Electric vehicles often use regenerative braking systems, which help recharge the battery during braking. The new MOT rules include specific tests for these systems to ensure they are functioning correctly. Inspectors will check the effectiveness of regenerative braking and ensure that it integrates smoothly with the traditional braking system.

Brake fluid and components

While regenerative braking reduces wear on traditional brake components, the 2024 MOT rules still require a thorough inspection of the entire braking system. This includes checking brake fluid levels, the condition of brake pads and discs, and the operation of the braking system. Ensuring that both regenerative and traditional braking systems are in top condition is essential for vehicle safety.

Structural and Electrical Integrity

Chassis and suspension

Electric vehicles often have a different weight distribution compared to traditional cars due to the battery placement. The 2024 MOT changes include specific checks for the chassis and suspension to ensure they can handle this unique weight distribution without compromising safety. Inspectors will look for any signs of stress or damage that could affect the vehicle’s structural integrity.

Evaluators will examine signs such as stress or damage, which could make a vehicle’s structure weaker.

Electrical systems

Given how intricate electric cars can be, the MOT test now encompasses a thorough inspection of their electrical systems. This includes wiring, control units and safety features like airbags and stability control. Safety wise alone it is important to ensure that these systems are working properly.

Tyre and wheel inspections

Tyre wear and pressure

Electric cars tend to have a higher torque compared to conventional ones, leading to increased tire wear. The new MOT regulations require that tire tread depth be checked by inspectors and that it meets the minimum legal standard. Additionally, the tyre pressure will be examined in order to ensure it falls within recommended range since improper pressure can affect the vehicle handling and efficiency.

Wheel alignment and balance

Proper wheel balancing and alignment are essential for EVs due to their instant torque and weight distribution. Now, in the MOT test, there is a check on balance and alignment, providing even tyre wear and optimal handling. When wheels are misaligned, uneven tyre wear may occur, and drivers’ feelings might be affected negatively.

Summary and implications for EV owners

The 2024 rule changes reflect the increasing numbers of electric cars on UK roads, as well as their rising complexity. These changes mean EVs are eco-friendly & environment-friendly but also safe and dependable. This implies that owners of EVs should give more attention towards maintaining them, especially battery, charging system and electrical parts.

Preparing for the MOT Test

To prepare for the updated MOT test, EV owners should:

  • Regularly inspect the battery and charging port for any signs of damage or wear.
  • Ensure that high-voltage cables are intact and have not been improperly repaired.
  • Keep the vehicle’s software up to date by installing manufacturer-released updates.
  • Monitor tyre wear and maintain proper tyre pressure.
  • Check the regenerative braking system and traditional brake components.

Benefits of the new rules

While these changes may require additional attention from EV owners, they ultimately enhance vehicle safety and performance. Regular maintenance in line with these new standards will help prevent potential issues, ensuring a smoother and safer driving experience.

The future of EV maintenance

As electric vehicles become more advanced, we can expect further updates to MOT regulations to keep pace with technological developments. Staying informed about these changes and maintaining regular vehicle checks will be essential for all EV owners.

In conclusion, the 2024 MOT rule changes are a positive step towards integrating electric vehicles into the UK’s automotive landscape. By addressing the unique aspects of EVs, these updates ensure that all vehicles on the road, regardless of their power source, meet high standards of safety and reliability.
