How to get your EV charging stations safe, reliable, and compliant with the support of TÜV SÜD

How to get your EV charging stations safe, reliable, and compliant with the support of TÜV SÜD

The world is continuously moving towards more sustainability and greener alternatives. The mobility and transportation sector is addressing this change and an increasing number of vehicles are getting electrified. Having a robust EV charging infrastructure is, therefore, a key element in this transformation process.

TÜV SÜD provides services to help EV charging infrastructure suppliers and operators overcome industry challenges. Our contribution in this sustainability journey is, that the products are safe, reliable, and compliant with regulatory standards.


How TÜV SÜD can support your EV charging station business



Our services for EV charging station manufacturers and operators

As your independent third-party technical service provider, TÜV SÜD has extensive knowledge and expertise in the field of EV charging infrastructure.

TÜV SÜD supports you from the early development stage, such as initial design and testing to the certification completion. The service ensures that your business will meet international standards, as well as market and regulatory requirements for safety and quality, which allows you to gain faster market entrance.

Your benefits are:

  • Compliance assurance
  • Improved product design
  • Global market expansion
  • Seamless integration
  • Fast market entrance

Amongst that, TÜV SÜD provides a wide range of services across the entire charging infrastructure solution.

  • Electrical Safety

    Charging solutions must be designed and manufactured to comply with the relevant electrical safety standards and guidelines. This includes the integration of safety features such as earth fault protection, overcurrent protection, and insulation systems to prevent electric shocks.

    The aim is to make the product safe for both the user and the environment. By implementing appropriate safety measures and adhering to regulations, manufacturers can ensure the safe and reliable operation of their products.

  • Interoperability

    Interoperability refers to the ability of EVs from different manufacturers to charge at different charging points, regardless of make or model. It promotes a seamless and hassle-free charging experience for EV drivers.

    Our interoperability service helps suppliers ensure their charging stations are fully compatible with a variety of EV models and charging standards.

  • Bidirectional Charging / V2G

    Vehicle-to-grid (V2G) technology allows electric vehicles to not only charge from the grid, but also return their stored energy to the grid - creating a two-way flow of electricity.

    We offer a range of services to support in the implementation of Vehicle-to-Grid (V2G) and Bidirectional Charging systems. Our team of experts is equipped to assist with all aspects of these technologies, from initial design and testing to final deployment.

    By conducting comprehensive testing, we can help you to reduce development costs, improve product performance, meet regulatory requirements, and gain a competitive edge in the marketplace.

  • Environmental testing

    Environmental testing is also an important consideration when it comes to EV charging infrastructure solutions. It needs to be designed and tested to ensure durability and resistance to environmental factors such as temperature, humidity, and vibration.

    Environmental testing can help identify potential weaknesses in design and materials that could lead to malfunction or failure. For example, extreme temperatures or humidity can affect the integrity of electrical components and wiring, leading to safety hazards and potential damage to electric vehicles.

  • EMC Directive 2014/30/EU

    At TÜV SÜD, our experts are well-versed in the EU standards and guidelines governing EMC Directive 2014/30/EU.

    We provide comprehensive support to manufacturers to ensure that the product meets the required immunity and emission requirements and limit values.

    Our preliminary tests during the development phase help to integrate EMC measures early on and at a cost-effective rate. Our EMC services include immunity and emission tests, as well as electromagnetic field testing for personal protection, and evaluation of harmonics and other network disturbances.

With the broad range of services, TÜV SÜD ensures the safety, quality, and compatibility of your products while driving your business forward - anywhere in the world! Join our sustainability journey.




By obtaining an EV charging infrastructure certification, you can demonstrate to your customers and stakeholders that you mitigate risks and hazards, and that you are committed to creating a safer and more sustainable world. Feel free to contact us at [email protected].




  • What are the challenges for EV charging station manufacturers and operators?

    One of the biggest challenges for EV charging infrastructure suppliers is navigating the complex certification and testing requirements across different jurisdictions, adding to their regulatory burden.

    • To meet the international standards and regulatory requirements for safety and quality
    • Achieving interoperability and conformity of technology and products with local electricity supplies, guaranteeing seamless integration and optimal functionality
    • Environmental factors/extreme weather like heavy rain or wind and extreme temperatures
    • Cybersecurity threats, due to hacker attacks
    • Managing the certification process
    • Costly and time-consuming processes to enter the market
  • What is charging infrastructure testing?

    Charging infrastructure testing is the process of evaluating the performance, safety, compatibility and compliance of EV charging stations and connected elements. It contains various tests and inspections, as well as certifications to ensure that the charging infrastructure meets industry standards and regulatory requirements.

  • Why is charging infrastructure testing important?

    Testing of charging infrastructure is critical to ensure reliable and secure operations of EV charging stations. These tests help identify potential problems, such as electrical compatibility issues, safety hazards, or compliance issues.

    By conducting these tests, charging station manufacturers and operators ensure that their charging infrastructure meets quality standards, functions efficiently, and EV users have a seamless charging experience.

  • What types of tests are performed during charging infrastructure testing?

    Testing of charging infrastructure includes a wide range of tests, such as:

    • Electrical safety
    • Charging performance testing
    • Compatibility testing
    • Communication protocols
    • Electromagnetic compatibility (EMC) testing
    • Insulation resistance
    • Leakage current
    • Grounding resistance

    These tests determine whether the charging infrastructure complies with the relevant standards and regulations.

  • Who should consider charging infrastructure testing services?

    Charging infrastructure testing services are essential for various stakeholders involved in the development, installation, operation, or regulation of EV charging stations.

    This includes EV charging station manufacturers, contractors, charge point operators, installers, utilities, regulators, and facility owners/operators who are seeking compliance, safety, and optimal charging infrastructure performance.

  • How long does charging infrastructure testing typically take?

    The time required to test a charging infrastructure depends on several factors.
    These factors are the complexity of the infrastructure, the number of tests needed and the specific requirements of the project.

    Depending on the scope and scale of the testing process, testing timelines can range from several weeks to several months. Based on the specific project requirements, we can provide a more accurate estimate.
