Omission of 48-volt electronics is particularly surprising in Hyundai's E-GMP vehicles, which incorporate various other advancements like 800-volt charging. Hyundai has even introduced a solution that does away with the old-style lead-acid 12-volt battery in some of its hybrids —but not any of its EVs thus far.
