Nissan has done a good job of installing CHAdeMO DC fast chargers at all their dealerships. I own a Leaf (bought used for $10k), and this allowed me to travel significant distances in spite of the small battery. Granted, this is a huge pain because:
1) Charge rate is 50kW peak, less than half of Supercharger’s 120kW.
2) Leaf battery is small, so you need to stop like every hour or so to charge.
3) 1st gen Leaf battery has no cooling. That’s right, none. Not even air cooling. It relies on thermal mass of the battery & very slow leakage of heat through the structure of the car. This is sufficient for daily commute usage, but Quickcharging produces heat. After 2 or 3 quickcharges, the battery is hot so quickharging rate reduces to more like 15-20kW to reduce heat production (power lost to heat is proportional to current squared, so halving charge rate halves the total heat per unit energy). Teslas and Bolts don’t have this problem as their batteries are liquid cooled.
So you end up only being able to travel 200-300 miles in a day even with Quickcharging. And because of the small battery, Nissan needs a lot more chargers to enable a given trip.
The new Leaf is supposed to have a >200 mile battery and 100kW charger. So about where Tesla was in 2012. But the existing charger network for CHAdeMO is only 40-50kW. Not too bad for an emergency stop, but if your whole trip is that slow charging, it’s significant.
BTW, Teslas can use Chademos with a $500 adapter since the CHAdeMO standard is the basis for the Supercharger standard. Also, CHAdeMO is capable of bidirectional charging, so it’s possible to do vehicle-to-grid with a Nissan Leaf. CHAdeMO is a better standard than the CCS one, but unfortunately most other EVs are using CCS.
And one big advantage Tesla’s Supercharger has is the plug is much smaller (and I believe cheaper to make!). CHAdeMO and CCS plugs are huge and unwieldy. And no one seems to be seeking a more sleek design like Tesla’s.
Fortunately, though, it’s not TOO expensive to provide both a CHAdeMO plug and CCS plug, since the expensive power electronics are the same, just a different protocol and plug, so many DC fast charging stations have both.
