Re: Canion Battery Readings

I have owned my imiev for almost 4 years and been driving 77777 km. My 80% capacity guarantee expires in 14 months or 22222 km. I am positive that I have a range decrease, but it is very difficult to calculate how much. So how do I open a guarantee case against Mitsubishi if I need to? What 80% cap...

Re: A bad cell and a reduce range

I will collect data for future comparisons. Collecting data for Wh Reg on charging will be difficult because Canion often crashes especially on a long period of 5 hres. Mine crashed also all the time. When I removed almost all the ticks in "Settings" the stability improved. I just kept &q...

Re: Canion Battery Readings

In answer to bobakka's 20% loss post, I would go back to the point that the BMU "masks" the battery degradation by limiting how low the cell voltages go until a minimum is reached and then the true capacity loss starts to be noticed. If I understand you correct your hypothesis is that the...

Re: A bad cell and a reduce range

So there is only 12,000W available to turtle and max 13,000W to road side assistance. My old bat. pack after 1½year used 13,000W at 17.5% Soc, at 12°C, light headwind, slow road. And 13,700W at 8.5% Soc, 21°C, faster tail wind, high hyway speed. Is this a good battery pack ? It could be that it is ...

Re: A bad cell and a reduce range

I would like too perform some tests on this new pack. Do you have any suggestions for future reference ? Pier I have the following suggestion and you need Canion and an external kWh-meter. 1. Charge to 100% SoC 2. Drive and use energy to get down to at least 20%SoC (maybe down to 10%) - write down ...

Re: Canion Battery Readings

Mitsubishi uses the amp hour storage of the pack as a reference. I support your view there. Amp hour is easy to measure and calculate. Our cells are rated by Yuasa at 50 amp hours with a nominal voltage of 3.6 volts. .. if you found during the M.U.T. III test that your pack had 39 amp hours capacit...

Re: Canion Battery Readings

Charge efficiency for a 10 Amperes charge is 88.0 %, for my 16A charge, 81.2% Hi BlueLightning Is the 16A charger less efficient than the 10A charger? I thought it was the other way around. And how do you calculate charge efficiency? I find that WhReg is around 77% of what you call "Wall Kw-h&...

Re: Canion Battery Readings

I have done som more test. Yesterday I started with 99,5 SoC and drove until 12.0, charged up to 96,5, drove down to 13 and charged back up to 99,5 The resulting Canion screenshot is below. https://www.dropbox.com/s/u30w12uocdc8ni3/pict_2014-12-06_22-41-40.png?dl=0 https://www.dropbox.com/s/u30w12uo...

Re: Canion Battery Readings

In addition, I had my car's battery capacity checked for reference when it had 30 miles on it by the dealer with the M.U.T III and it had a capacity of 49.5 amp hours. How does M.U.T. III work? Does it measure available capacity or total capacity?? When my car was testet a year ago at 60000 km it h...
