Will not preheat when fully charged.

Fri Feb 01, 2019 10:16 am

New owner still figuring out the many quirks and features :lol: .

My preheat and whatnot seems to work as intended while the car is charging(120v standard charger) but not once fully charged (still plugged in). I unplugged and fiddled around a bit with it. Plugged it back in. Charge light goes on. I test preheat. It works. Car becomes fully charged a minute later and turns off preheating. Is this operating correctly? Am I missing something. I envisioned plugging the car in the evening before, it becomes fully charged over night, then using preheating to get it ready for the commute in on the houses energy instead of the cars battery.

Other thing I can't figure out is how to get the clock to display 12 hr, with AM/PM. If not possible I'll just have to join the rest of the world and learn 24 hr clock.

cjm1219, welcome to the forum and hope the car is meeting your expectations.

Interesting observation about the car locking out the Remote when fully topped up. Inasmuch as I almost never fully charge, I haven't experienced this and perhaps someone else might comment?

In my case, I try to time my cold-weather (uh, cool weather by most standards as our temps so far this winter rarely get down below 40°F) charging by reducing my EVSEUpgrade.com modified Mitsu EVSE to only draw 6A on 120vac and using the Remote I time the power turn-on to give me about 13 bars at about the time I'm ready to leave in the morning, thus she's still charging when I subsequently use the Remote to pre-heat. That's my 'winter' regimen in the belief that it keeps the battery less-cold and also running it on 120vac reduces the stress on the OBC.

Incidentally, we use the term "charger" to denote what is better-termed the On Board Charger (OBC) built into the car whereas the inline-cord thingy that comes with the car is more-awkwardly and generically called an EVSE (Electric Vehicle Supply Equipment). Not to worry, everyone knows what you're talking about when you say charger. ;)

I *thought* is did preheat when the battery was full - It's been years since I used it though, so my memory may be wrong. If you're preheating with the OEM Panasonic 8 amp EVSE, it doesn't hardly get warm if you do it while the car IS charging, I do know that - The car uses most of those 8 amps and there's not much left over for heating. If it's something you're going to be using fairly often, a 240 volt L2 EVSE would be a good investment. It warms up pretty quickly on 240 volts

Thanks for the info so far. I have been reading a lot on here and trying to get up to speed. This is my first EV. I'm enjoying the hell out of the car. I'll use this as intro space as I didn't see a place for that on this forum.

I always been interested in EVs but they have been out of my reach financially as I have sworn off car payments and I don't have a ton of extra cash laying around. Over the last few years I have been buying old BMWs and fixing them and enjoying them and selling them on. I've had three 318ti in the past few years. Yeah, I like weird cars but you people do to apparently. I figured I'd go electric this time instead of another old bme Anyhow, I was introduced to and almost bought a i-miev from a co-worker months ago but didn't happen and have been looking for once since. I almost settled on a Leaf(boring and too big) but then my i-miev popped up for sale and I talked them down to $4k. Which seemed like an ok deal for this part of the world (Pacific Northwest). The plan is for my girlfriend to commute in it (8-10 miles round trip) and then use it for all our running and the city in the evening and weekends. I have been using it the last couple days just to fully check it out before I hand it to her to use. I love driving it around town. It's so zippy and handles city traffic great. Parking is hilariously easy.

Anyways back to the preheating. It seems like it should work even if the car is fully charged. The idea is it would be using the house energy instead of battery energy to preserve range. I imagine in the future we'll get in to a schedule where we won't be charging it to full capacity every night as it seems like that's better for battery health, so this may not be an issue. Although the preheating thing is one of the most exciting feature for EVs so would like to use that every morning if possible.

Other quirk I noticed today. When I lock the doors with the key remote the blinks flash but on occasion it will also honk but not every time. Not sure what the difference is.

cj, first off, I think you'll find that there is very rarely a need to fully charge the car. With an 8-10-mile round-trip commute and then some running around town you can easily stop charging at around 12 bars and be comfortable on a daily basis. You simply use the Remote to tell the car when to stop charging. My rule of thumb using the 2012 Mitsu unmodified EVSE (i.e., 8A at 120vac) is four bars for five hours of charging. BTW, here's the link about using our Remote:
http://myimiev.com/forum/viewtopic.php?f=19&t=2780

There are many threads on the topic of care and feeding of the battery pack: in a nutshell, the worst thing you can do for the battery is to fully charge it and then leave it sitting in the hot sun. Unlike a lead-acid battery, our Lithiums as happiest sitting at around half-charge. I normally charge the car only up to 12 bars.

With the car at around 12 bars and still plugged in, irrespective of whether it's still charging or not, you should have no problem using the Remote to activate either the Heat or Defrost. That will immediately take care of the problem you're experiencing.

IIRC, clicking the key fob twice will result in a honk, but IIRC that may also be one of the programmable features. Ooooh, just remembered:
http://myimiev.com/forum/viewtopic.php?f=19&t=3108

Meanwhile, the next time I've fully charged my car and it has stopped charging I will see how it responds to the Remote.

i tried using the OEM Level 1 EVSE 120 VAC at 8 Amps for overnight charging during some recent cold weather, and used the remote for defrost in the mornings. The car charged up fine, but the defrost was a joke--it didn't do squat to melt the frost or ice from the windshield.

By comparison i have never had an issue with using remote defrost to clear windows and preheat the car on cold mornings when connected to my Blink Level 2 EVSE 240 VAC at 13 Amps.

Sometimes it does take a few attempts with the remote to get the functions activated, e.g. turn on time, cut off timer, turn on AC or heat or defrost, etc.

The state of charge of the battery didn't seem to matter as much as the 120 vs 240 VAC situation.

Thanks for the links JoeS. That explains the honk some times and not others as I have been using the auto lights most the time but had them off the first day I was driving it.

Once we get to actual using the car for commuting next week I'll figure out a schedule that works well for keeping the battery at a happy level.

Reading more and thinking about it, it makes sense that the pre conditioning wouldn't work when it's fully charged. I don't think EVSE is sending any power at that point so it would have to flip back on somehow to run the preconditioning.

The car came with a 15kw level 2 EVSE but unfortunately my current house setup would make it difficult/expensive to install. Panel in the basement on the opposite side as the garage. The garage is detached and only has 1 20amp 120v circuit going to it. I only know enough about this stuff to be dangerous. We have to move in about 6 months so hopefully the new house has a better setup to use the level 2 EVSE.

OK, last night I fully fully charged Mitti at 8A 120 vac until it stopped charging this morning. Without unplugging the car I then used the Remote to turn on the heat. No problem, it started heating normally, albeit slowly, but it worked just as it should!

The EVSE is controlled by the car. In my case, it woke up and showed the orange 'charging' light as the heater was operating.

The remote is at best - to be kind - sorta flakey. It amazes me that a company built a car as well sorted out as this one and the same company was somehow responsible for the remote they sent with it - Maybe they turned that project over to a junior engineer who wasn't allowed to touch anything when the car was developed

Many times, you gotta try things 3X or 5X before you get the desired result . . . . if you ever do at all. I suspect this is why so few owners use it, and if you don't use it regularly, you won't remember the exact steps you used last time to get it to work. Many years ago, I used one of ours to pre-cool the car as my wife was getting ready to deliver a wedding cake in the 90 degree August heat and since then, they've both been stored in the junk drawer. I'm sure they'd probably need new batteries before they would do anything

So, play with it some, read the book some, play with it some more before you give up on it . . . . and if you eventually do, know that many of us have gone before you! :lol:

Thanks for testing that out for me. Guess mine isn't operating quite as intended. I used preconditioning this morning without any issue as the car only about half changed. I will have to test it again at full charge.
