Best way to charge??

Regarding the not charging to 100%

last Friday afternoon my Imiev only charged to 99.5%. (now thinking off peek outlet could have switched off before fully charged)

Charging on Sunday went 100%

Charged last night to 100%

Best way to charge??

Post by g4qber »

after racing at the RAC DTEC
and charging at average temp 30 deg C,

charged last night 95.5%
batt temp was still around 30 deg C Think.

Kurt I presume you use the standard mitsu EVSE?
I'm just wondering if the EVSE can make a difference.

I shall have to take more note of the batt temp when charging overnight.

scantools dongle is behaving itself, though I just accidentally pulled it out the other day cos I forgot to turn on the imiev and assumed that it has frozen.
currently it is paired to the xperia ultra z.
reason being that I can put it in the glovebox (GB) when going round the track.
the nexus 7 seems a bit too thick and the GB doesn't close.
I make sure that nexus 7's bluetooth audio is NOT on. Nexus also seems slower than Xperia

Skype on xperia in portrait mode can't access text entry field, need to use landscape mode.
this is cos the xperia is so narrow. Which is good for shirt pockets.

g4qber,
        Yes stock 2012 10A EVSE.

There is one 2nd theory for the not 100% SOC. Perhaps it has something to do with trying t charge form a all ready high SOC to 100%. For example charging from 14 bars to 16 bars. Because the week that it happened to me I was just topping up my car from 50% SOC to 70% SOC each day perhaps 4 or 5 times over the week then on the Friday I charged from 70% - 100 (well 99.5%) The two charges after that were from a low SOC back to 100% and it had no problem.

I think some times the SOC meter can get a tad out of whack. Try a few full charges from a low SOC perhaps.

I tried my nexus 7 with blue tooth audio off and wifi off it logged fine on the 1 1/2hr drive up but coming home it dropped to 0fps after 45mins. Coincidentally it alined with the time I turned the stereo on to listen to the radio and it went to blue tooth first before I switched it to radio, though as mentioned blue tooth audio was off on the nexus & but perhaps the radio gave off a signal that messed it up?

Its funny how it can work 100% for 1 1/2hrs and other times drop out ofter 5 mins.

At this stage I'm finding it difficult to justify the economics of spending the money.

I think the most practical unit would be the charge amps 6,10,16A. Just to have the option to charge at 16A and to have the 6A option. Some times I want to take advantage of lots of sun and charge faster other times I want to charge slower overnight.

But the cost was something like $1000?

That price $1000 is = to 1000w additional offgrid PV providing 4kwh pr day for 20 years+ or 5000kwh of off peek electricity at 0.20c kwh or 38,000km of EV driving at 130whr km plug to wall.

Something to think about...I'm just a cheapskateImage

aussie dollar was close to parity with US dollar.

would you consider getting the Holden 10A volt one? Made by Clipper Creek. Even still has the 16A label on it, cos they use the same cable for their 15A unit.

it is only $AUD350

I think for my needs my stock Imiev evse hangs on the wall in the garage Monday - Friday , I don't take it with me weekdays as all my trips are under 100km return. Then on the weekends I pack it in the car and head up the coast it stays in the shed there until Sunday....yes once I forgot to pack it and noticed 1/2 way Image Only did that once.

Yes $350 sounds more reasonable for a EVSE though I don't think I would purchase one unless mine was broken. Then it's a good chance ..excuse to get the adjustable one.

I have my name on the waiting list for a local version of the variable amp one - hopefully thru testing /compliance by the end of the year.

I would like it primarily to charge more quickly at caravan parks etc to travel a bit more than my current 100km radius from Adelaide.

what do you mean by local version adelaide-ev?

what speeds do you normally travel city vs country to get 100km range?

I've made it to York 111km @ 70kmh with undulating roads; 0 bars, warmish weather 24C, 8kmh headwind

I assume she means she is waiting on one approval for use in Australia of the 8 you've listed only a g and maybe c d e. would be approved for sale in Australia, and have the RCM / c-tick mark allow distribution.

I would be nice if the Swedish one can be sold locally i would buy one.

I have an Open EVSE half built, but have yet to finish it. The Max current the Imiev will take is 13.5A (limited by the 3300W charger).
We charge our Imiev off-peak, & my wife drives about 75km round trip every day. It fully charges in less than the approx 6 hours the o/p gives.
I have 5 KW of 60c feed panels, & fitted another 2.5 Kw for my carbon offset for the car (Net feed tariff). In the future I will probably go off-grid once the batteries become economical (or I recycle my Imiev batteries)

I would love an interface that would let me use power from the car: the capability is there (via the Chademo socket) (if you used 20% that would be over 3Kw, which would be close to our night time use for full-tariff power). there is an inverter available in Japan that runs off the Chademo. (probably 110v 60Hz)

Yeah I heard they used the imiev batteries in natural disasters in Japan - brilliant idea!!
