700km on a single charge: Mercedes says it's in it for the long run


Re: No Need to Panic

No, you’ve missed the hidden assumption, in the phrase “a lot of these will be overnight”

It’s *possible* to make it work, but it will be an epic ClusterFK unless someone actually manages the technology correctly.

“Overnight” is not how plugging something into a socket works today. Most of the population gets home at (roughly) clocking off time, and will plug their car in when they get home for “overnight topup”. But the plug doesn’t *know*. The entire topup would happen within 10 minutes after they get home, at 350kW per car, pretty much synchronously across the country. Immediate catastrophic blackout.

The way to manage this, is simply to limit the *average domestic* charging to 10kW, so it automatically spreads the load overnight. And coincidentally doesn’t require change to the domestic infrastructure.

It’s fine to have a fast-charge plug, but it has to be priced at premium if not punitive levels to prevent people lazily using it as the typical case.
