Despite some similarities, fundamental disagreements abound on many levels.[1] The United States follows the narrowest approach, imposing safety and performance standards at the vehicle-level, but no battery-level requirements, and only basic charging safety specifications. The European Union's approach is significantly broader, addressing the vehicle, comprehensive requirements concerning battery packs, and more extensive charging safety regulations. China's EV safety regulations are the most puzzling.
