What is NACS and J4300 and what automakers support the charging standard?

In the race to create a mass-market electric vehicle, automakers developed a number of charging standards. Different manufacturers had disparate ideas on the best method to juice up their electric models, and thus the EV charging world was splintered into a mess of adapters and plugs that varied by carmaker. CHAdeMO, J1772, CCS, GB/T — it’s enough to give you a headache.
