Group 2 - The charging standards for EVs vary by region, with China's "GB/T" standard gaining popularity and many local companies developing chargers that support this standard [5]. - In Japan, the "CHAdeMO" standard is prevalent, with chargers typically offering 50 to 90 kilowatts of output, which currently does not support megawatt-level output [7]. - Tesla is focused on building its own charging infrastructure globally, using the "NACS" standard, which has become the most common charging standard in the US, adopted by companies like Toyota and Ford in North America [7].
