What is EV charging infrastructure?

EV charging infrastructure refers to the charging facility and connectors required for the efficient operation of alternative energy vehicles and is the most important technology in enabling the success of electric mobility. A safe and seamless user experience is key to the end user’s overall acceptance and satisfaction within the EV ecosystem. This can only be achieved with a safe, reliable and convenient EV charging infrastructure.

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 you with EV charger testing and certification?


Why is it important to test and certify your EV infrastructure solutions?

Manufacturers of EV charging stations and connectors are developing equipment based on new technologies that require extensive testing and certification services according to relevant standards by independent third-party service provider like TÜV SÜD.

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.

Our dedicated services offer you several benefits:

  • Ensure your products meet international standards, as well as market and regulatory requirements for safety and quality
  • Improve your current product design based on relevant testing results and avoid costly rework
  • Achieve compliance with relevant requirements to enter new global electric vehicle markets in time
  • Ensure compatibility of your technology and products with local electricity supply

TÜV SÜD SUPPORTS YOU IN TESTING AND CERTIFYING YOUR EV CHARGING INFRASTRUCTURE PRODUCTS  

As your independent third-party technical service provider, TÜV SÜD combines extensive knowledge and expertise in the field of EV charging infrastructure with global accreditation. Utilizing our globally accredited laboratories (DIN EN ISO/IEC 17025), we assist you in testing your products and overcoming existing challenges.

We provide the following comprehensive services to ensure the safety, quality and compatibility of your products while driving your business forward.

  • 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.

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.
