Re: Weird AC behaviour while fast charging

I have seen the same behavior from the AC during DCQC. From watching individual cell temps on Canion I think it has to do with the disparity between cooler and warmer cells. As we know the cell cooling is far from uniform in the pack. Seems that my AC shuts down when the difference between the warme...

Re: Passive cooling ?

[i]The cabin blower can work well for this if it is run at mid speed and no higher. Doing so with the key on isn’t practical since it runs a bunch of other systems (unnecessary wear and tear) pulling more than 7 amps total. 7 Amps? Measured where? If I check Canion when car is in ACC, the current d...

Re: Passive cooling ?

So, obviously leaving the key on all night every night and supplementing the 12 volt system with a battery charger is not a long term solution but the data from doing it leads to one. I did that all night ventilation on my wife’s car and it had an uncharacteristically long charge cycle needing 12 ba...

Re: Passive cooling ?

If you say the 12V battery is charged during L1 or L2 charging, then a possible solution would be to leave the cabin blower on during charging and have an EVSE with ajustable output (6A to 14A, for example). If you have a general idea of how much %/hour it charges at each speed, you can set it up s...

Re: Passive cooling ?

Actually, once I turn the AC to the battery, I always get some cold air on my feet. More than I would like, too. The vents are not 100% sealed. That's interesting, On my car it is a very good seal. No discernible airflow out of the floor vents when in Battery vent mode. It's hitting 105 F here toda...

Re: Passive cooling ?

The thing to watch for when trying to run the pack fan is that the cabin HVAC has the battery damper flipped and the vents set to the floor. Otherwise, you're not going to get much airflow through the pack. A good reminder. I assumed anyone deep into this thread would remember that, but likely a re...

Re: Are the 2012 models getting too risky?

Two 2014's here . . . ES is the only model offered for 2014, 2016, 2017. The steering wheel is not heated on either of ours. Twin seat heaters and DCQC standard though. :)

Re: Passive cooling ?

So I've been looking at the main battery exhaust blower and wiring, etc, in the shop manual. Looks doable to add in a relay to run the blower powered by, perhaps the onboard charger 12 volt relay activation. That way when the charger shuts down (and the DC to DC shuts down too ) so does the fan. Als...

Re: Passive cooling ?

I personally avoid that method ever since I tried it once and nearly emptied my 12V battery. Turns out it's only charged during "ready" mode. About other solutions, well I posted in another thread about portable chademo chargers which can work from single-phase power. We can regulate thei...

Re: Using the battery as an emergency supply

Aerowhatt, Do you know what is the transfer rate of the iMiev dc to dc converter? It is rated for an output of 80 amps and 14.4 volts . . . However as measured those are a bit off BTW what does SOC stand for ? As Don pointed out it refers to state of charge: 100% is full and 0% is empty This soluti...
