Re: [EVDL] EVLN: Offset Supercharging degradation w/ pack balancing

2015-08-03 Thread ph...@bill-collins.net via EV
I see a couple of things wrong here that make me question the whole article: 1) The author seems to think that supercharging will be harder on the pack than fast charging a LEAF because the supercharger is higher rate. BUT, compared to total pack capacity, the supercharger is the lower of the

A couple of comments: 1) Losing a bar of battery capacity at 20,000 miles is NOT normal for the 2013 and newer LEAFs. We had 98% of original capacity left at 30,000 miles on our 2013, others are reporting similar numbers. 2011 and 2012, especially in hot areas do lose significant capacity, but

Absolutely never trickle charge any type of Lithium Ion battery Nissan refers to their included Level 1 EVSE as a trickle charger. Charging is still completely under control of the car's BMS. I'm not sure why Nissan says it's not for routine use, but it doesn't hurt the car. I suspect

I'm planning on doing something similar, but haven't gone beyond buying 3 cells on ebay, for a practice run on a lawnmower. Please post details as you work them out. Did you buy the car through one of Copart's auctions, or just walk into a salvage yard and ask for a LEAF? Bill --

It may be that I'm misunderstanding this idea. However, I find it a little disconcerting. I can maybe see it for a leased EV, though I don't think I personally would accept it. As I understand it, they would pay you to allow them the control. If they don't offer enough money to interest you,

That price doesn't look right. The Leaf has two batteries. Each has 24 cells, not counting the internal 2s2p (or whatever). I bought three of these from HAC for roughly $2,600 each. If your price really is for a complete pack, then it's half the price I paid per KWH. Yes, it was a complete pack,

I've been looking at using LEAF batteries also. Since I'm planning a lower voltage system than the LEAF, I'm planning on paralleling groups of three packs. I noticed that the packs bring out the center tap between the two series sets of cells and I'm planning on paralleling the center connections

They must have really improved the Alaska highway if it's now passable in a Tesla. BTW, slowing down and enjoying the trip is a concept that's quite familiar to owners of VW busses! -- next part -- An HTML attachment was scrubbed... URL:

[EVDL] Conversion advice

2014-08-10 Thread ph...@bill-collins.net via EV
A few years ago I decided to convert my '98 VW Cabrio to electric. At the time, a Warp 9 motor and Zilla 1K controller seemed to make a lot of sense, and are probably one of the best combinations today for a DC conversion. Since I've now put 90k miles on the car as an ICE (after buying it

Re: [EVDL] Miles Remaining

If only, in their focus groups, they had asked the question: would you rather have an accurate remaining-kwh meter or an fairly inaccurate remaining-miles meter? The 2013 (and I assume 2014) have percentage remaining as one of the selectable options for the center display. Not quite kwh, but
