Quickly launch new products, and boost consumer confidence in Europe and beyond with the trusted NMi seal of approval.

More than just an increasingly popular car option for consumers — as an alternative to traditional fuel combustion engines — electric vehicles (EVs) play a progressively significant role in meeting climate change goals. Consequently, market signals point to a bright future for EVs, including their charging solutions.

As government and industry increase investment in development and expansion of electric vehicle charging infrastructure to support anticipated amplified adoption, manufacturers and other stakeholders of EV Charging Solutions will increasingly need to meet performance, and compliance requirements, all of which currently vary across different countries, regions, and industries. It’s an ever-changing landscape with complex processes that can be a challenge to negotiate. That’s where NMi can help.
