1MB at that time was like USD 3-5k, easy!!

20MB SCSI HD!! Quantum?

My first Mac was a IIvx (early 90s) featuring a Sony CD-ROM with caddy! It was amazing!

Guess what, it still works!

I don't know if I got used to it, or if computers kind of lost its joy, but I don't have the same passion for todays stuff.

I'm still evaluation the i-Miev purchase....

Dang, I had one of those also. Upgraded the memory to 1M and added a 20 MB hard drive, thought I had the King. Used it extensively from 1985 through 1994 or so.

Now we have iMacs, MacBook Air, iPad, iPhones, ho hum...

Guys, I must say that I'm still unsure about buying it...

If something like this http://myimiev.com/forum/viewtopic.php?f=23&t=3897&start=40#p35561 happens to me, it's a game-over. Ok, super rare, but chances are great on a 8y car sitting in a tropical country. I'd still have the cells and the motor, but what a cost of time and money...

BTW, is this true??

Furthermore, and I quote Yuasa's PDF http://www.gs-yuasa.com/en/technic/vol5/pdf/05_1_021.pdf "regarding the calendar life, capacity retention of 65% is anticipated after 10 years storage at 25 °C" in storage, this is a lot!

I'm waiting to check the car in person, let's see...

I'm a bit sceptic...

That's why you need to either see a complete cell data scan from the dealer, or get the OBDLink LX from scantool.net and use the android app, "Canion", to check the cell voltages. You could get each of the 88 cell's voltage to see if one or more is weak or out of family with all the rest.

This should be read out while the car is fully charged and ready to go, then drive it down to below 2 bars on the fuel gauge and see how far it travelled from the odometer, then charge it back up to full and wait for the balancing to occur and read the cells again.

Several cycles like that would be ideal, but even just one complete cycle like that would tell you much about the pack's condition.

By the way, the obdlink tool works with any obdii car, just using other apps to display data and trouble codes. so it's not a waste of money to buy one--it is a handy tool and i've used it to reset DTCs on several gasoline cars and vans.

The iCarsoft 909 scanner can also read the data and any stored or set diagnostic trouble codes, and allows clearing of some DTCs. No phone app for this one, but it works for all mitsubishi and mazda cars.

Good luck, i hope everything measures okay, but if it doesn't then probably better to avoid it

Trying to get it to turtle (below 9.5% SOC - no bars at all) is best to observe possible imbalances in the cells. So yes, Canion is a must-have. It's unlikely that you'll find someone in Brazil that will lend you an OBDLink, since triplets owners (imiev, c-zero, ion) there should be quite scarce. Still, you could try to search in a local auto forum or something. You might have some luck.

I also bought a used triplet with close to 7000km in very good batery condition, but mine came from France, which is a considerably different climate. Battery capacity measuring apps didn't exist at the time, so you have an advantage I didn't back then.

Just another data point on battery health. I pushed my luck and drove 3.4 miles on the turtle in my 2012 with 86,500 miles on the clock this past weekend. That's farther than I've gone since the only time I killed it, a year ago at 5 miles into the turtle. Next morning after recharge? 54 miles RR and 62 RR on the following day.

So folks,

I've tested the car today. Couldn't run Canion or the MUT3. By the time I showed up, the car was plugged (EVSE 240V) and charge was complete. Yet two bars were missing on the Charge Indicator! The estimated range was 51km (± 30miles). And driving it conservatively proved the the guessometer is ok.. With the AC on, range dropped to two thirds.

So... Bad luck, right?

I tried to plug it on a BMW L2 charging station, but they use a different plug! Is there an adapter between the standards?

Best regards!

Clemente

If the "fuel" gauge is not indicating the full 16 bars after charging has completed using either level 1 or level 2 EVSE, then there is at least one bad cell in the pack. The charger cuts off when the cells reach the highest voltage allowed (4.15V) and the charge current drops below the cut off threshold. Then it calculates the fuel gauge based upon the average voltage of all the cells in the pack. If one or more cells is lagging, then it brings down the pack average and that is seen in the not-full and less-than-16-bars gauge reading. Of course Canion or the MUT3 could show you immediately which cell(s) were the culprits.

If Mits would replace the pack under warranty, then it would be a good find and purchase. if the price was discounted very low due to the defective pack, and you were skilled at electrical repairs, then the pack could be opened and the bad cell replaced with a used cell from a salvage yard pack. Otherwise it is just a big el gallo azul that will drain your wallet.

So...

I had the opportunity to drive it again. This time though it did charge to 100% prior the test drive. Diving like a grandpa, ± 70km/h 100% flat, it did 91km, with 21km and 4 bars left. Is this ok?

PS: it lost the first bar after just 3km. Is this ok?

Sound like the pack is 'waking up' after its long hibernation. My naive theory is that some capacity should return with regular use, though the first few weeks of regular use should also be when any defective cell shows itself.
I don't see your original mission parameters. If a car with 50 kilometer range could meet your needs, just as it worked for those of us with lead-acid cars 'back in the day', I'd take of roll of the dice on this car....
In the worst case, the parts that aren't VIN-locked should be worth reselling, if you have the patience for that...

Good point!

The motor is quite nice! For a VW Bus or something else... I'd love to use the battery for an off-grid solar project. Any good thrird-party BMS?

What are the odds of sourcing a compatible controller for the motor (DC-AC)? Is the DC-DC converter VIN locked too? CAN bus managed?

I hate this VIN lock and CAN buss proprietary crap..
