As the market for advanced electrified vehicles (xEVs) continues to expand globally, developers and original equipment manufacturers (OEMs) are confronting a growing array of regulations and standards addressing the safety and performance of the rechargeable battery systems used to power these vehicles. Although many of these regulations touch on similar considerations, there are also important differences that must be taken into account during the various stages of battery design. Further, the regulatory approval process in key markets is often unique to a given country, and requires a specialized approach to navigate successfully. In this white paper, we’ll discuss the key safety and performance issues that must be addressed in all xEV battery designs, as well as the specialized requirements that apply to xEV battery systems in the EU, the U.S., China and other important markets around the world. We also discuss how TÜV SÜD is working with OEMs in the automotive industry to navigate the homologation process and to gain global market access for their products.
