Warning Light after hill climb

Tue Aug 26, 2014 8:57 am

Has anyone else had the Exclamation Mark warning light come on following a lot of high speed driving and a major hill climb?

This hasn't happened to me before, or since. Basically, I had a very busy day with my Meever.

8am to 8:30am-- Drove to get some coffee and do some city sight seeing: 15 miles round trip, charged at home.
9:30am -- Drove to Mall for phone replacement: 12 miles there, another 12 back, charged while phone was getting worked on at mall.
11am -- Drove home, Charged while eating lunch.
12:30 pm --- (car is nearly fully charged now) Off to the in-laws house: 42 miles doing about 70mph. Last stretch is a 3 mile very steep (might be as much as 6-7%) hill climb, also at 70mph.

Get to top of hill, even road from here on out, take a left... all is good... all is good... Wait, what's that light? It's the "Electric Motor Warning Light" The one that looks like an exclamation point :!: ontop of a car. OH NO!

Car keep going, it's acting like nothing is wrong. I'm not sure what to do, i'm only 1 mile from my in-laws at this point and the car is doing fine. I decide i'm to worried to keep going, so I pull over about 1/2 mile down the road and turn the car off. Ok, count to 20 and turn it back on. Lights gone. All is good again.

What happened? Maybe it's just the i-MiEV version of a temperature warning? Maybe I over did it a bit and the car got a little pissed? Has anyone else had something like this happen? The car is doing just fine since. No warning lights or anything with our normal use.

Ideas? Advice?

What were the ambient temperatures at the time?

JoeS -- High 80's. Maybe 92%, tops.

looking at my driving and charging times, I basically had current running into and out of the battery, non-stop for 5+ hours.

Is it just me, or is the Exclamation Point Over Car warning light our "catch all" trouble light? I looked, and we don't have a Temperature warning light, just this thing.

Never a trouble light, and with heavier duty than that, BUT my heavy summer driving usually includes a CHAdeMO session or two, which allows some battery air conditioning.
I'd log cell temps with Canion on the next such expedition, or figure a way to log coolant loop temps.

I've seen my motor temps hit 130F on warmer days (~85F) driving on main roads.

Did you happen to have CaniOn running (if you even have it)? Temperatures and voltages?

Reading the owners manual, it says between 40 and 45º C in the battery or motor, the turtle light would appear. Not the warning light. So for me that is strange.

Never saw such a thing with mine. Canion showed sometimes values over 40ºC, but we now suppose they were wrong, but never saw the turtle because of the heat.

Nothing like stop for a while like you did. I think most of the times, when it disappears, everything is fine.
