What is Euro 7 and how does it affect the electrification of long-haul, high-payload vehicles?

28th November 2023  |  Electric vehicle

The European Commission announced Euro 7 standards that seek to reduce air pollution from non-exhaust emissions. It also includes requirements for the lifespan of electric vehicle (EVs) batteries, setting a minimum for each type of vehicle.

The new standards highlight the need for specialised components for long-haul, high-payload vehicles to reduce non-exhaust emissions and enhance battery life.

In this article, we unpack the new Euro 7 standard, the impact it has on commercial EVs and how high-quality components can ensure compliance.

How do the Euro 7 standards affect long-haul, high payload EVs?


Recent scientific studies and research have shown that vehicle tyres contribute to micro and nanoplastics found in the environment. These are known as tyre and road wear particles (TWRP), and potentially contribute to adverse health and environmental effects. As a result, Euro 7 seeks to regulate these pollutants, with the gradual elimination of them being a long-term goal.

In the context of trucks, their tyres have been discovered to be less polluting than passenger car tyres. This is due to truck tyres consisting mainly of natural rubber (~34%), whereas the main component of passenger tyres are synthetic polymers (~30%). This raises the added value of electric truck electrification in the move to reduce air pollution. Nonetheless, tyre abrasion and composition needs to be taken into account in modern electric truck design to minimise the amount of TWRP.


Traditional cast-iron disc brakes have been discovered to produce potentially harmful pollutants. They can produce black carbon which is the second strongest contributor to global warming, as well as other pollutants that are potentially harmful to people’s health.

The disc and drum brake systems of ICE high-payload vehicles emit a significant amount of pollutants as they have the highest rate of brake wear compared to most vehicles. For electric truck designs, the integration of regenerative braking systems reduces the amount of wear and abrasion that takes place. This is because a portion of kinetic energy is absorbed by a regenerative motor that converts it into electrical energy. As a result, less pollutants are produced when compared to traditional brake systems, highlighting a key advantage of high-payload vehicle electrification.


Euro 7 also includes standards on minimum battery lifespan to both maximise the use of each EV and limit the amount of battery waste. This comes from the concerns of growing lithium-ion waste as a result of widespread electrification. Euro 7 outlines the following standards for battery durability and lifespan of N1 vehicles (trucks): 75% minimum performance after 5 years or 100000 km (whichever comes first), and 65% after 8 years or 160000 km.

For long-haul truck electrification, there are key aspects that affect battery lifespan.

  • Temperature – Due to the high voltages and currents used in electric trucks, high temperatures are a common challenge. In context with battery lifespan, operation at high temperatures can accelerate their degradation. This calls for sufficient thermal management in the electrification of trucks.
  • Charging speed – Long-haul vehicles require significant energy capacities to have high driving ranges. This requires fast charging solutions to be efficient when compared to ICE alternatives. However, incorporating fast charging without specialised components can lead to battery degradation through mismanagement of charging and discharging of the battery.

How specialised components enable your electric truck design to be compliant with Euro 7

The challenges of non-exhaust pollutants and battery lifespan of electric trucks can be solved through specialised high-voltage components.

  • By integrating lightweight components in your design, you can maximise weight efficiency and reduce the amount of wear and pollution from tyres.
  • Through the integration of energy efficient components such as terminals and relays, you can incorporate effective regenerative braking systems that help reduce the abrasion and pollution from braking systems.
  • By incorporating specialised components for thermal management and high-speed charging, you can maximise the lifespan of your batteries as well as the driving range of your long-haul vehicles.
