Re: Cold package for my MiEV

According to this chart, below -22 F, the car will not start or charge, maybe the pack was below this temperature? Do you happen to know what the temperature was when it shut down?

It kind of hit me by surprise so I am not sure the exact temperature on the first day but -22C is possible. I had difficulties with the remote connecting this morning and the thermometer said -19C but it could have been -22C

Thanks for the great graphic

Please excuse the naive question, but do all i-mievs have battery warmers and if not how can I find out if mine does?

No, they don't. I believe ALL the Canadian version cars came with it and maybe all of the SE Premium cars as well but otherwise I think it was an extra cost option. I know my non-Premium USA SE version did not come equipped with it

For any car kept outside in extremely cold climates, having the folks at EVSE Upgrade modify your Panasonic brick might be money well spent

Not only will it give you the ability to charge using L2 @ 240 volts at up to 12 amps if you wanted/needed to, but you could also dial down your L1 charge rate from the standard 12 amps (Canadian EVSE) to 10 or 8 or even 6 amps. This would enable you to ensure the battery is always under charge overnight during cold weather. Select the amperage which would give you a nearly full charge at about the time you expect to leave home the next day

GaryW, welcome to the forum. What an experience for you in this weather as a new owner! I wouldn't read too much into this because of such an extreme temperature, and it does sound as though your i-MiEV was protectiing itself.

I've had my Mitsu Panasonic brick EVSEUpgraded and concur with Don's suggestion for slowing down the overnight charqing, although when you turn on the Remote to preheat in the morning it means that more of the energy will be taken out of the battery to preheat the car than if you have the EVSE set at 12A.

On some of the EV forums there has (appropriately) been some discussion about charging at low temperatures. If I recall, a very low charging current at the temperature extremes was suggested, but it was unclear if this applied to all lithium battery chemistries.

As far as using the car, if you're like most of us you will soon find the iMiEV becoming your PRIMARY car, with the ICE vehicle reserved for long trips. Last Sunday for the first time in a long while I took my ICE car for a 50-mile (one way) trip to an evening party instead of the iMiEV simply because I needed to start using it's old gasoline, although I'll admit that uncertainty as to the availability of a public charging station played a factor in this decision. :roll:

The 120V charging cord that came with the i-miev has a switch on it to choose between 8 and 12 amps. Is that the same thing or similar to the EVSE mod?

Nope, you lucky dog- no EVSE control switches for early adopters- the modified Panasonics from EVSEupgrade.com are reprogrammed via a paper clip shorting the pins of a live unit! :shock: Kinda scary to the uninitiated.

Also, the Upgraded unit allows you to charge at 240 volts at up to 12 amps - That's twice as fast as you get on 120 volts at 12 amps
