Battery pre conditioning

[upa]

I know this may be a little premature with warm weather still here but has anyone been able to verify the battery pre conditioning mode does indeed turn on battery heating when a DC charger is selected as a destination on the NAV? Failing any first hand experience is that the description of its function in the manual?
Thanks

I can't think of why it wouldn't work...that's exactly how it is described in the manual

Thank you for the reply. Do you know if you can activate battery pre conditioning before you can depart on a winter morning?
Sorry about the questions as I am still waiting for my GV60 and I don't have the benefit of a manual. Is there one available online?

The battery pre heating is a big deal for me in Canada after owning an EV without it which effectively tripled my winter DC charging time vs summer temperatures. This was supposed to be a software upgrade on my Ioniq 5 but I now hear that folks in the US with appropriate battery heater/heat pumps will not get the appropriate software because its apparently too much of a hassle for Hyundai to manual upgrade the several affected modules. I fear this may also be Hyundai Canada's position and am trying decide if this is a good enough reason to trade in my Ioniq 5 for GV60.

You can set the time of departure and the car with pre-heat and then charge to be ready for when you leave if that's what you mean.
I'm in Canada as well and this function is very important for me as well...as I assume it is for all Canadians

Do you know if schedule pre heat prior to departure includes the battery warmer or just the cabin heat? I ask because this feature to schedule pre heat of cabin already exits on older Hyundai EV but the pre heating of the battery pack seems to harder for some reason.

I believe it does

You can just google it & get the US version, I don’t think the Canadian available online yet. There’s just a couple of things in there that we don’t get, “Phone as a Key”, “Key Card” etc.

I had a look through the entire US owner's manual. The only reference I could find to battery pre conditioning was :

" You can select or deselect the Battery conditioning mode. The Battery conditioning mode is efficient during the winter time when the high voltage battery temperature is low. This mode is recommended to improve driving and DC charging performances during winter by raising the battery temperature to an adequate level. However, the driving distance may be reduced as the energy is required to increase battery temperature. Also, if the battery temperature is low during driving or when scheduled air conditioner/heater is activated, this mode is operated to improve driving performance and charging performance. However, the mode is not operated to ensure driving distance when the battery level is low.?

So it sounds like it will heat the battery up when plugged into an EVSE(probably minimum level 2) with scheduled heating. It alludes to improving DC charging performance by raising battery temperature but does not specify how it will do that or what conditions must be met( other than battery not being low, how low?) to initiate this mode prior to DC charging. Is it a manual switch on or is it activated by putting a DC charger into NAV as destination? It always makes me a little nervous when manufacturer leaves the descriptor purposefully vague.

 

[fredf]

I believe it is activated only by putting a DC charger into the Nav destination.

Hmm. I can't recall if I saw it for the GV60, but most EVs will warm the battery (if needed) if the scheduled departure feature is used and the car is connected to power.

Yes Tesla does this but this is a new feature for Hyundai EVs. With previous Hyundai EVs if you had winter mode on, were plugged into a level 2 EVSE and charging during the pre scheduled departure warm up it would also turn on the battery heater if your EV was so equipped. If you did not meet all those conditions it was cold battery for you. I have awoken to battery packs as cold as -20C, sure the cabin was warm but sucks if you have to do any highway travel/DC charging that day.

 

[fredf]

yes, I believe if you are plugged in at home then it will warm the battery as well

Yeah, I’ve noticed that ”vague” description in several places in the manual, some areas where it’s almost a self explanatory situation, they go on & on. In other cases, where one would think they would give a fairly in depth description there’s nothing, weird.

 

[Looney100]

The GV60 manual is easily the worst of any vehicle I’ve owned in the last ~15 years.
The index is woefully inadequate, and -perhaps as a result - material isn’t where it should be.

So what will happen when my car sits outside for 10 hours in , say -40 while I am at work? There are no chargers at my office. I haven't gotten this far in the manual yet.

You’ll get into a very cold car with a very cold battery, and once you start it up, a fair bit of the battery capacity will be used maintaining cabin temperature, and you may find that acceleration is limited because the battery is too cold to meet the motors’ demands at WOT.

If you pull up to a DC fast charger with a cold battery, charge rates will be limited until the battery warms up.

Well, as long as it starts. My commute is all of 15 minutes, so i am not too concerned about range (I charge daily)

It will start but in extreme cold make sure you try to keep your SOC in the upper range if possible especially if parked outside. Its quite possible to experience voltage sag with a cold soaked battery pack from unequal power delivery delivered from the individual cells, relatively large demand from heating and traction which may result in very limited power output overall.

In my Kona EV I had a situation where I arrived at my office with 35%, parked for 8 hours in -25C and then proceed to get on the highway to be immediately greeted with turtle mode and an inability to accelerate beyond 90km at least until the battery warmed itself up. In "normal" temps the only time I could invoke turtle mode was with a SOC under 5%. The Ioniq 5 is a great winter car but you have to be aware under certain circumstances it may behave in a manner you don't expect particularly in extreme cold.

" unequal power delivery delivered from the individual cells,": that's why you are supposed to slow charge (120 or 240 V) your battery. to 100% from time to time to make sure all the cells are matched. Fully charging is the only way to do this.
