Tesla I believe has well over 100 mile range
Range anxiety is primarily caused by charge capacity, not rate of charge. My guess is that Nissan's charge rate was determined so the 24 kwh pack could be charged "overnight", the most common charging scenario that was foreseen. Had they doubled the pack capacity to 48 kwh, they'd likely have used an on-board charger with twice the capacity. To reduce range anxiety they would have to increase both the pack size and charge rate, as I see it.cdub said:Tesla's home charger is 53 miles per hour. Holy moly. If all of the standard 220 chargers were that.. there would be NO range anxiety.

Why didn't the let the LEAF charge at a higher rate..
If the Tesla can charge from 0 to full in 4 hours and it has a much larger battery pack... couldn't the Leaf pack technically be full in 2 hours with the better onboard charger... that would be a much more attractive option to reduce range anxiety.

I also assume they think that DC fast charging will predominately be used for anything faster than "overnight".
While these assumptions may not always be true, it gives me a way to make sense of their possible intentions.

By that, I mean a charger that plugs into the DC Fast Charge port on the car, but pushes 6.6kW into the car from a special home DC EVSE? Seems like there would be a market for that if the price was right...
TimeHorse said:How long would you be willing to wait to drive your LEAF for each mile.
- 11 minutes: Free in US / Canada
- 5 1/2 minutes: Free in Europe
- 4 minutes: with 3.3kW built-in Charger and EVSE
- 2 minutes: with 6.6kW Charger upgrade (possible)
- 1 minute 20 seconds: with 10.5kW Charger upgrade (very unlikely)
- 45 seconds: with parts hacked from a Tesla
- 4.5 seconds: using DC Fast Charge with Battery damage

Would that be possible? Probably would void your warranty though.

just that electrical service alone with no charger is in the $50-100K range

garygid said:Many 30/32A (6.6 kW) EVSEs will be available, but the LEAF's on-board J1772 charger will only use 15 or 16 amps.
So, an AC-to-DC "controlled" power supply to take the J1772 as input and then connect to the LEAF's DC-QC input, doing the needed communication with the EV ... would give us about twice as fast charging from most of these "public" (or home) EVSEs.
Allowing this "Plan B" Charger Box (PBCB) to be powered from 50A 240v at RV Park outlets ... would give us about 80% charging in under 2 hours (12 kW).
Maybe the "Plan-B" box would be a good DIY project?
TimeHorse said:I agree! I was not intending to imply that a home would have a 480V 400A CHAdeMO station. Even a 70A or 90A circuit is a bit much for home wiring needs. Seems to me the 8kW jumps in Charging standards is annoying if you miss it by a couple of kW so you have to jump 20 more amps in your wiring gauge and receptacles.
