To enhance the usability and benefits of the ZEV/ZET standards, they must be grounded in the practical realities of the enabling ecosystem, which in turn depends on the existing standards. Not to mention, such standards are largely contingent on how well current ecosystem needs are understood and mapped. Keeping this in mind, the graphic below illustrates the system dependency structure among the components of the ZEV ecosystem and the standards guiding ZEV adoption, including policies, tariffs, and specifications.
Done right, this not only strengthens the overall ecosystem but also enables timely, evidence-based evolution of ZEV policies, vehicle, battery and charger specifications, tariff designs, keeping pace with the realities on the ground.
