The discussion focuses on the challenges and potential innovations in electric vehicle (EV) charging infrastructure, emphasizing the high cost of existing galvanic isolation methods used in fast chargers. The proposal suggests substituting this with a simpler system involving a second ground wire for grounding verification. However, there are notable concerns regarding safety, potential regulatory challenges, and the impact on existing vehicles if a new standard is established. The commenters express a range of opinions on improving charging accessibility, standardizing battery packs, and the feasibility of innovations like two-way charging and coin-operated charging stations.
