Re: Battery Failure Data

I do. My friend's coworker just got a new C-Zero with 80 cells. The most important differences are smaller pack (14,5 kWh) and prolonged warranty 8 years/100.000 km like you have. He lives only 70 km away, so I can drive there and check whatever you need to be checked and post here. So let me know, ...

Re: Battery optimization

620 Wh is the most common value, I think. I think with a new one we should see that value. And in a new one the weakest cell will be around 3,5 / 3,6 V at 0,0% of SoC. My friends C-Zero, year 2011, 14.000 km, averaged 148Wh per 1% SOC, so his value for 5% is 740Wh. I don't know about 50% SOC voltag...

Re: Battery optimization

I also notice a drop of about 15% of range. Mine now with 84.000 km and almost 5 years. Can you tell me how much it charges from 50% to 55%, seen by Canion? Mine charges about 540 Wh. I'l let you know but last time i measured this value, it was 62 Wh in average for 0,5 SoC so 50-55 620 Wh should go...

Re: Citroen C Zero v Renault Zoe.

£70pm up to 7500 miles a year, or £45pm up to 3000 miles a year. That's for a purchase price of £13445. Comparable sized EVs without battery lease are considerably more expensive. As I said, I'm only looking at various options at present. And my reasons for considering an EV aren't just economic. I...

Re: Citroen C Zero v Renault Zoe.

John, what about Zoe's battery rental costs? I believe in UK also you can't buy but only lease the battery. If so, I would make a calculation about profitability. The price of monthly battery rental and electricity cost is at least 8€/100 km. That makes driving Zoe far more expensive as any small di...

Battery optimization

Technical "expert" at Citroen told me I should visit my dealer to do a battery optimization. He explained that every couple of years every c-zero should be connected to a tester, which needs about four hours to finish the process. He claimed that range and battery health should improve sig...

Re: Turtle riding (How far has the turtle brought you ?)

I do it quite often. I noticed I can rely on the SOC Canion reading. The car stops at 0-2% SOC and every % equals at least 1 km of easy driving. It happened a few times I came to a planed charging station with less than 5% SOC w/o any range anxiety.

Re: Great idea for pre heat pre cool without imiev remote

I just don't care about missing remote in Citroen C-Zero. On cold days coming in a few weeks a small 240V 2 kW fan heater does the job quicker and better than integrated car's heater. I just need a power strip to charge and heat the car simultaneously home or at charging station.

Re: How long will it be before electric cars will be the nor

I believe the answer is simple. EVs will outsell ICEs when prices will be equal and range will reach let's say 200 miles. Even today there is no real technical reason for so high prices of nowadays EVs. All depends on the political and corporative will and decisions.

Re: Charging blocked due to high cell temp?

Usually I hear fan starting right after ch. cable has been plugged in. Red charging light with SOC bars on dashboard come on right on the start of charging. I checked outlet - no problem detected. Yesterday it happened again. I came home with 37-41°C cells temp. range. Charging didn't start, red cha...
