'LEAF can be charged from a standard 13 amp house socket (using the supplied cable assembly). At this rate it takes 10 hours to charge from empty to full. Nissan recommends you get a home charging box installed - which is a dedicated and safely installed 16 amp vehicle charger. It also reduces your charging time down to 8 hours for a full charge. We are working with potential partners to develop an offer for the home charging box. Your Nissan EV dealer will be able to assist you with these chargers closer to receiving delivery of your LEAF.'
In the UK, we do not appear to use the term EVSE or identify Level 1, 2 and 3 power sources. You will see that Nissan UK even erroneously refer to the 16 amp power source as a 'charging box' and 'charger' whereas, we all know that the charger for a 230v input is within the car. I think that the US term EVSE is far more appropriate.
I hope this helps! Bob.
See so it takes 10 hours from zero to 100%. But you (OP) probably will start with more than zero and you are aiming for 80%. So you are really charging more in the 60% zone and should easily fit into the low TOU rate from ~12a to ~6a (?).

2 bar lost at 35,339 miles, 25 months.

That's really cool. My daily commute is 22 miles total.

Every other month or so I will head on a longer trip of 65miles to one of two places. One place is motorway most of the way (although a large portion of this is restricted to 50mph) and the other place is long winding single lane roads but is a bit up and down. I believe both of those journeys should be possible - at least until the pack starts to wear down over 3 years or so.

I guess I just need info on how badly the British weather will effect our range.

So, most of the time I plan to charge maybe every other day. I imagine I will be charging from 30-35% up to 80%.

Thank you all.

Nufkin, you'll want to keep your speed down to 65mph on the motorway regardless. I just did a 70mph trip and the LEAF sucked down ~20% more juice than it did at 65mph.

70mph should use a bit more than 10% energy than 65mph... 20% is too high...

And yet it did. I went down from ~7 miles per bar on the SOC graph to no more than 5 miles per.

Gary,

I think you mis-typed here. My measurements show my LEAF consistently drawing 15.5a while charging as the initial generation LEAFs have only a 3.3kw (3.7kw measured) power converter in them. The L2 EVSE in my garage is capable of passing 30a (listing maximum) and is fed by a 240v, 40a branch circuit (technically, the EVSE could be rated as high at 32a on a 40a branch circuit but it's not for some reason).

Yes, incorrect typing, possibly due to a "brain cloud".
I will edit to fix that post.

Well, that is 40% more energy - even worse than your quoted 20%. That would mean that if you get 85 miles range at 65 mph, you'd only get 60 miles range at 70 mph. My calculations show that you would have to drive 80+ mph to drain the battery in 60 miles.

Something is not adding up here. (And we're getting OT)
