  1. Lithium Iron Phosphate, the optimum static storage battery?

    Power, Fuel, Alt Energy and Environmental Impact
    I continue to read around on Battery storage solutions, both domestic and grid scale, and often the public criticisms are about battery health, material availability and safety. Cobalt-type cells (NMC etc) seems to be the default solution for vehicles thanks to their energy density, but in...
  2. What to expect from Renault re my leased Kangoo batteries

    General Renault Z.E. Discussion
    Today I bought a 2011 Renault Kangoo ZE van for £5,900 inc. VAT. Renault said that the lease battery state of health is 78% so I expected it to have a range of roughly 110x0.78=86 miles. I bought it fully charged and gently nursed it up the motorway at 55 mph but it was into the red zone after...
  3. Renault Zoe, Kangoo & Twizy Battery Cells

    Renault ZOE
    Hello fellow Renault enthusiasts. I am working on a second use battery storage made from batteries from Renault Zoe, Kangoo & Twizy electric vehicles. I am contacting the forum regarding information about these batteries, for example specific data sheets regarding the li-ion batteries (with...
  4. Tesla Battery Day - which may or may not happen

    General Tesla Motors Discussion
    Elon has been teasing an important Tesla Battery Day for some time now, but for some reason it has fallen off the list of upcoming events. I wonder if the battery technology has hit a snag - or there has been an issue with battery patent applications. Whatever, here is a video that provides...

  6. New Leaf Safety Recall

    Nissan Leaf40
    I have a New Leaf 40kwh registered in September 2018. I've just received a recall notice from Nissan asking me to bring the car to a Nissan dealer to have a software update to rectify a potential safety issue with the Automatic Electronic Breaking System. That's all fine but in the same letter...
  7. Warranty on batteries?

    Volkswagen Golf GTE
    If I remember correctly there is a 6 year warranty on the battery in Golf GTE. This is what I probably heard or believed when I bought mine 3,5 years ago. Does anybody know what is covered in this warranty? What degree of degradation does one expect in this time? Or, what is still ok and what is...
  8. Does Heat affect charging?

    Nissan Leaf40
    Yesterday, the weather was very hot - 35 degrees in the South East. I plugged my 40kWH Leaf into our home Pod 7kw charger as usual, at about 6pm, with about 25% charge remaining to charge overnight. To my surprise, by this morning, I had still not received the Charge Finished notification on...
  9. Renault threatening to switch off my Renault Zoe battery.

    General Renault Z.E. Discussion
    Renault threatening to switch off my electric vehicle. I have bought my Renault Zoe car completely outright (not on hire purchase or lease) and they are threatening to remotely switch off my vehicle. Can they do this? Has anyone had the same issue?
  10. Battery Lease vs. Buy Outright

    Renault ZOE
    Looking to buy a new Zoe ZE40 but I'm debating whether to lease the battery or buy it outright. The only reason I would not want the battery lease is that after 10+ years or so (time I hope to own the car for) whenever I decide to get rid of the car or part exchange it, the lease would not...

  12. A new 'personal' best.

    First Generation Ampera and Volt
    Wee bit of background. Car wasn't used for a week, left plugged in and fully charged. When I went to head to work today I forgot to preheat, Torque was reporting a charge capacity of 86% (used to be 83%, then jumped to 87%). Charge up today and when I went to come home Torque was showing 90%...
  13. About to order a new Zoe.....

    Ice Breakers
    I expect this has been well and truly covered but cant find it on the forum. Is there a concensus on battery leasing v ownership? I hate being tied into a third party on the leasing side but I can see the argument that if I sell it in six years with an owned battery it will possibly...

  16. How big's the battery? / What's happening?

    Renault ZOE
    Hi y'all, I'm interested to know what's going on with my Zoe/Homecharge unit. My car was plugged in to charge last night and was unplugged this morning before going out. No pre-heating. The Polar/Homecharge Dashboard shows the 'Duration' of charge (basically when the plug was...
  17. Renault Fluence EV purchase advice

    General Renault Z.E. Discussion
    I'm interested to purchase my first EV. Spotted a Renault Fluence EV for sale but worried about the obvious battery longevity question. So scanned around this form, but have not yet found some of the answers to my questions; I'll enquire about the current range and SOH and have listed some...
  18. How are replacement battery prices coming along?

    Nissan LEAF24 & LEAF30
    My 30 is still smugly on 12 bars, but I'm aware that won't last forever. Likewise I presume battery prices are coming down year on year and, by the time I face the horrors of replacement, the price may bear no resemblance to what it is now, but I'm curious to know how they are coming along, and...
  19. Leaf 30, 21k miles, losing one battery segment?

    Nissan LEAF24 & LEAF30
    The car 4 months away from end of PCP. I was going to keep it, but over the past couple of weeks I’ve noticed that sometimes I’ll have a battery segment missing and sometimes I won’t! I’m assuming that this means that the capacity is falling or about to fall but 21k miles seems to be a bit low...
  20. Loss of range?

    General Mercedes EV Discussion
    I'm looking at buying a 2014 b-class electric from a dealer, off a three year lease in New Jersey, 26,000 miles. Car is in nice condition, but does not have Range Plus. This is the car: https://www.datamb.com/vin/NLpwWEbnl4vEBz8a5 The problem is that the dealer is unable to charge the car...
