Next-gen Leaf to be unveiled on 5th September!

[EVangelist]

According to Electrek "The Japanese automaker confirmed this week that it will unveil the vehicle on September 5th. It should be available at dealerships shortly after."

Although that probably means dealers in USA, not here 

Nissan really need to get their act together here if they want their new Leaf to be a "Tesla killer".

What we've seen recently, as detailed by a few owners here in various threads, is the exact opposite

So true!

Telsa is going to kill them more like it

The thing I find interesting is the rumours that the new Leaf has a Mennekes port to replace the J1772. If the new Leaf can do 3-phase 22KW from the Mennekes port, it can use Tesla destination chargers. Also with a simple (cheap) adaptor and you could use showground 3-phase. This isn't an unreasonable expectation as the Zoes have had this capability for years. Actually I think some Zoes can charge at 43KW from 3-phase.

Couple this with a bigger battery and suddenly range anxiety goes away.

At the right price this could be a very competitive package.

Yes mark, the Zoë rapid is 43kw, I do get an honest 20minute charge on the big multi DBT units with my French Zoë. Then car is noisy charging though at that rate, the cooling fans run high out front, and the battery fan rumbles underneath. The mennekes plug gets very warm, in fact they warn you not to hold the cable, just the plug.

I know the Japanese are biased to J1772 and Chademo, but I'd hope they would learn from their French partners how to charge cars where there is lots of 3-phase power around.

If you can do 43KW from 3-phase you don't need Chademo to charge at the same speed, and the infrastructure savings would be huge. Yes the cost of the car would go up, but I think this is the obvious way we have to go to make them practical. At least in Austalia (NSW) which has bugger all infrastructure.

Even just having my 10KW Setec has opened up so many possibilities for my Leaf. I can visit relatives in Bateau Bay, and Berrima to visit the maze and buy Jam.

I can't wait for 5 September.

I understand that the Zoe uses it's inverter to charge from 3-phase, the same as when you use regen to charge the batteries. Thus keeping the cost of the on-board charger down. How clever is that?

Are you able to confirm this Stewart?


PS. Just to clarify, the car's inverter takes power from the batteries and changes it into 3-phase, suitable for driving the motor. But it also takes care of regen where 3-phase power comes from the motor (now acting as a generator), and puts it back into the battery.

Clever indeed. Why not use existing inverter for import/export function when possible. High power too!

You mean "Vehicle to the Grid". No reason that couldn't work too. Good idea.

Yes that's correct, that's the chameleon charger in the Zoe Original model, the newer model does only 22kw not the 43kw of the original. But it gets better range due to a more efficient motor design, in house by Renault. The Renault inverter and motor also works much more efficiently at low charge levels like from a home charger. The older model would take 10-12 hours off a domestic plug, only 70% efficient. Realistically few people use the 43kw rapid, there are 5 times more 22kw chargers around, and home 7kW wallbox units.
