The other new info is luggage volume - 330 Litres. Prius is 446 L.

In Cu Ft - Leaf is 11.65 cu ft.

Portuguese leafs will get:
6m cable, 16A, 309-2 plug

Maybe we in Portugal won't need the L2 charger to get 8 hours instead of 10 hrs?
Will the inboard car know how many amps are available? What appends if we pug it in to a 12 AMP socket?

Seems the Portugese version allows for an extra 3amps :P What would be the cost for replacement cable ?

In Portugal, do you have 12-amp sockets and also higher-amp
sockets with require different plugs?

Hi,

Portugal has the same sockets as Germany, Norway, etc etc., which are usually rated at 16A, 230V, giving approx 3.6 kW.

In Britain the sockets are 13A, 230V.


Additionally, where three-phase is available, there are standard sockets for 3 x 16A, 400V/230V, giving approx 11 kW.

Wow, that is really "Giving Power to the People"!

Makes me wonder if the charger in the USA LEAF will draw 16 amps, or just 15 amps (if "offered" 16 or more amps by the "EVSE", of course)?

Seems unlikely that Nissan would "adjust" the on-board charger differently for each country.

So, for now, I am guessing that it will "eat" (draw) 16 amps at (almost) any voltage, if given the chance to do so.

This is a complete orientation to EV driving. The USPS electric vehicle was based on the Ford Ranger EV.

There are three important (input) parameters for any charger - input voltage, input current and the product of the two (assuming they are in phase), which gives the number of kW.

The charger will have a maximum input voltage (say 230V here) which is limited by the voltage the electronics in the charger can withstand. Then, there is a maximum input current - say 10 or 16 A, given by the limit of the electronics, but also by such things as the cable and especially the electricity plug and socket.

These chargers have advanced microcomputer controlled electronics, and the microcomputer can trivially be programmed to not draw more than 10, 13 or 16 A. This would mean that the batteries are charged with 2.3 kW up to 3.68 kW. It is not difficult for them (in fact it is a legal requirement) to make sure the UK chargers are limited to 13 A if they use a 13 A plug.

Of course, if you have only 110V (like in the US), you would need more than twice the current to get the same power - meaning massive cables and plugs for 3.6 kW.

Specs from EU press kit:
http://newsroom.nissan-europe.com/EU/en ... peid=21,10
http://newsroom.nissan-europe.com/downl ... aspx?41194
http://newsroom.nissan-europe.com/EU/en ... iaid=41193

Some new info, including max motor speed, battery voltage, etc.

Max. engine power 1) kW(PS)/min-1 80[109] /2730-9800rpm
Max. torque 1) Nm/min-1 280 /0-2730rpm
max RPM 10,390
Final drive ratio (AT) 7.9377

So it looks like they have it programmed to let the motor put out 280Nm of torque up to 2730rpm, but then have it trail off to keep horsepower flat above that (hp is a result of torque multiplied by rpm).
