Charge Anytime & pre-conditioning via Grid energy


Forum|alt.badge.img+2

Hi,

 

just had my hypervolt 3 pro installed and very helpful engineer. One thing I’m struggling with is how to use grid energy to precondition battery, before a journey.

i ask ChargeAnytime to be ready by 7 and I might be leaving at 8am, with my old 13amp charger, I could tell the car, leaving at 8 or even just getting it to defrost by manually setting it and it would use grid energy saving the battery for the journey.

 

i don’t mind that the preconditioning is on a more expensive rate, but I assume the charger won’t accept the request from the car and just use the battery. 
 

Is there anything I need to do, or is it just the way it is?

Hi ​@Colingray83 ,

I’ve had a chat with Hypervolt and they’ve said the Charger probably wouldn’t automatically fire up outside of the schedule so you may need to run off of battery to precondition.

Alternatively, you could run an Urgent Charge and then precondition that way - but it would be at standard (non-discounted) rates.

Hope that helps!

Are you sure you need to routinely pre condition your battery before a journey? Does your vehicles manual recommend this?

The advice I have received for my Hyundai is that pre conditioning is only required to facilitate a fast charge (at a public charge point) when temperatures drop much below 10 degrees centigrade. Without conditioning the speed of fast charge drops considerably. The implication is that battery conditioning is not required at home where perhaps your maximin charge rate is only 7.4kwh . I think I received the advice in a YouTube video but I don’t recall the advice as being restricted to my make of vehicle. 
What I do recall about that advice is that fast ccs charging at a public charge point when it’s cold and you have not preconditioned your battery can take an age.

I hope this helps.

I have just read your post again. Do you mean ‘preconditioning’ ie warming the battery to facilitate a charge or ‘conditioning’ ie warming up your vehicle on a cold morning before you drive? 
if ‘pre conditioning’ then my understanding is as above.

What prompted this debate for my vehicle is that on the Blue Link app the words ‘battery conditioning required’ appears in orange text at all times giving the appearance as highlighting the instruction. The general consensus is that it should not not be highlighted at all times, or at all.
I hope I haven’t misunderstood your point.

Hi , thanks for your comments. On the Tesla app, you can schedule when you want the car to be ready, Tesla calls it Precondition (appreciate that might be different from warming battery for charging) and makes sure the car is warm inside, though I think it may also warm the battery for regenerative charging. If it’s really cold regenerative charging gets switched off. Similar to yours it starts warming the battery for fast charge if driving to a charging destination.

 

Ideally, would prefer to do this from mains electricity rather than use up battery power, I think Tesla uses mains power if it’s available .
