Re: [EVDL] To fully charge or not to fully charge that is the question

Recalibration: that sounds like a breach of contract on Nissan's behalf. To be positive, overall I think Nissan has done a great job. But in this case, I'd fight back. When you by a leaf, you sign a contract and recalibrating the way the battery is measured sounds cleanly like a case of

Re: [EVDL] To fully charge or not to fully charge that is the question

Willie, Not dynamically, just a one-time upgrade (dealer visit required). Many Leaf owners who lost the 4th bar and thought they qualified for the warranty battery replacement were miffed to see the dealer really enforcing the Nissan requirement that the warranty will only be honored after the

Re: [EVDL] To fully charge or not to fully charge that is the question

That's what happens when you use LifP04 cells. You never know when a cell will go south for no reason. I have about 75 customers including my own conversions using NEW Volt cells and have NEVER had a bad cell in over 5 years. Who else can say that. Cannot vouch for those who buy used batteries

Re: [EVDL] To fully charge or not to fully charge that is the question

Simple, The EPA calculated the Leaf range based on the average of charging to 80% and 100%. Totally crazy, because anybody needing max range would charge to 100% but that was why Nissan removed the 80% option, even though customers wanted to keep it. I always charge to 80% to be gentle on the

Thanks Corbin If that's the case I wonder why Nissan dropped the less than 100% requirement from the newer 2014 and up vehicles? I guess I don't understand why fully charging and equalizing the cells would hurt battery life. Maybe just a hang on from the lead days :-). Mark Sent from my

Yeah, I don’t know why they would change their recommendation; people might have been complaining about the limited range when only charging to 80-90%. corbin > On Oct 4, 2016, at 10:12 AM, Mark Hanson wrote: > > Thanks Corbin > If that's the case I wonder why Nissan

Re: [EVDL] To fully charge or not to fully charge that is the question

Speculation, FWIW: If the 2014 LEAF really became OK to fully charge to 100%, that may have been based on performance monitoring of the 2013 batteries not showing degradation when charged to 100%. And that would imply that it may also be OK to charge the 2013 to 100% regularly. Or it may

Re: [EVDL] convert a mercedes

I agree with Corbin. You will need the transmission to get both decent acceleration and top speed, and also to make it easier for your wife to drive. I don't see why you want to keep the engine if you only need 30 miles range.You can get used Leaf or Volt cells at lower usable $/kWh than you can

Re: [EVDL] To fully charge or not to fully charge that is the question

Are you sure the 2013 cells were the same chemistry? I thought they were the older spinel type, not NMC. Anyway, worst case for decreasing cell life is high voltage and high temperature as shown by Dahn and other researchers, so most manufacturers recommend not charging to 100% SoC regularly. I

Re: [EVDL] To fully charge or not to fully charge that is the question

Lithium cells (of all chemistries) seem to have the fastest degradation when they are charged to 100% on a regular basis. The general consensus is to keep it in the 20-90% range. This is also what Tesla recommends for the Model S / X. I’ve also been charging my LiFEPo4 cells in my VW bug to

Re: [EVDL] convert a mercedes

Hi Gerald, The AC75 without a transmission will be very slow, and have a limited RPM range (i.e.: max speed is limited, or it is geared way too low for slow speeds). Home made hybrids are really way too difficult. If you don’t remove the engine you won’t have any space for batteries. My

[EVDL] To fully charge or not to fully charge that is the question

Hi folks In my 2013 leaf manual it says to not fully charge each cycle and only to 80 percent is preferred but in 2014 it became ok to fully charge. The chemistry is the same NMC nickel manganese cobalt cathode with a lithium electrolyte and a graphite anode. So did Nissan get it wrong? Is
