Lowering EV prices and longer ranges are more important to adoption than recharging speed but making “refueling” indistinguishable with fossil fuels will go a long way in EV ownership no longer be regarded less convenient than owning a fossil fuel car. However the key to five minute charging is safety to prevent thermo runaway and battery fires.
According to experts that will be more than enough for consumers, and that is why electric vehicles are going to win in the end. It’s all good news for EVs.
You are focusing in on the wrong thing. It is not that 5 minute charging is needed to make it more like fossil fuel vehicles or any safety issue, it is ONLY needed once there becomes lines at charging stations. So, in the heavy use EV charging stations in CA or once ownership numbers are large enough that there are long lines at the average charging station on trips. Other than that, there is no NEED.
Most people drive < 250 miles per day. Right now, "refueling" with fossil fuels is a hassle that needs to be more convenient. I have one L2 9.8 kW (charges at 40 Amps) wall charger at home, I charge both my EVs nightly. I never have to go anywhere or wait in any lines to have 80% charge every morning. Meanwhile the closest gas station to me has lines all day (BJs gas)...
Also, every rest stop I got to on the East Coast between NY and FL has long lines to get gas. You end up waiting 10-15 minutes to get your turn to spend 5 minutes filling up... All while us Tesla owners, drive up, plug in, go inside, finish, and leave in the same time.
