EV general discussion

I had the low battery warning come up on the EV for the first time in my ownership the other day :D. Totally miscalculated the distance I had to drive and the warning came up at 10%. The dynamic range said another 31 miles were available but it was night, lights and all the ancillaries that come with winter driving were on so I knew it would lower be than that. I wasn't worried though (honest!) and got home with 6% remaining.

What's the lowest you've drained the battery and has anybody actually ran out completely?

I think the lowest I've hit is 2% 5 miles on the gom. It was slightly squeaky bum time as I was picking up the little one and had hit an unexpected road closure with the only option to go back down and up a 60 DC for a few miles with no rapid charger closer than home.

My wife seems to get squeaky bum time if she has anything less than double her worst case mileage showing :o

10% is loads :D

I took my old Polestar to 2% once as I was driving locally around home and the number of warning lights (a tortoise) and sounds were unignorable! You could feel the power difference too.

It would be interesting to see just how much there is in reserve, Carwow style, especially with my EQC being particularly inefficient and my car insurance with Admiral coming with EV charging recovery as standard, but life with a 19 month old takes priority!
 
I got to 4%. Wasn’t really bricking it as there were 2 chargers along the way once I hit 10%. I tend to go take an executive decision on charging plans once I get to 20%. I’ve done 2-3 min splash and dash in the past.

Today is an interesting one, need to pick my parents up from Heathrow via Watford (starting from the west mids) Fully loaded with luggage in this weather means I’ll need around 5 min charge. But then I need to leave at 6am tomorrow for work where again ordinarily I’d need a full charge, won’t get back till midnight tonight so won’t be able to get a full charge. Let’s how well the VW software handles charging stops. Back 12 months ago I’d be sat here planning the hell of the trip, now I’m happy to take the risk.
 
about 4% but I wasn't worried as my mates house was close by.
the most nervy I have been was on the motorway it was pounding it down with rain with a very heavy headwind. I had planned a service station stop at the large place off M6 at rugby but realised I wasn't going to make it. I had my kid and wife in the car who is nervous at the best of times.

it was still ok once I made the decision to give up on my initial plan I just had to come off motorway sooner and charged elsewhere.

I have run out of petrol before but (touch wood) never run out of charge

0%, 0 miles remailing. I was 2 miles below 0 and wasn't particularly concerned as the car has only just applied a power limit of 70% of power, I reckon I could have gone another 10 miles or so.

I've never ran out.

The lowest I have gone while towing the caaravan is 10% but thats a different ball game and the loads on the battery are so much higher, you are talking about 500-550wh/mile rather than 220-250wh/mile for the same speed. Range disappears rather quickly and I expect the below 0 range will be non-existant due to the much higher draw.

3% for me in an E-TRON 50. It was complaining going over the Antrim hills that I would not reach my destination and showed -5% SoC at arrival. I knew… hoped it would regen enough on the way down. Luckily I was right.

0% in the the Ioniq (more than once), never worried though when you know the car well and you understand where you are, and where you can charge. Always have the 3-pin granny in the boot as well so can plug in almost anywhere at all.
 
Some good stories there of running very low! It's such a strange thing, I'd never worried when I was running low on diesel (apart from taking in all the crud at the bottom of the tank) but yet, even safe in the knowledge that I can charge at home the EV factor still gives a bit of anxiety.
 
2% for me as well. Doing a speed run to Eurotunnel Calais to make my train home after a trip. Knew there was a Tesla Supercharger at the terminal so decided to risk it, but it was a pretty nervous last 20 mins or so watching the range tick down!
 
I'd imagine that much like ICE cars, motorcycles, tractors and pretty much anything else that uses fuel, the engineers have designed in a significant margin for things like poor conditions, component degradation and perhaps most importantly, user error. Leaving a family stranded somewhere isn't something that engineers are keen on, and as a result will have as much of a buffer as possible.

Yep all batteries have top and bottom buffers. For battery health as much as for not leaving you stuck in the middle of no where

I got down to 2% determined to get home for a cheaper charge. Car kept trying to direct me to a nearby charger even when home was closer.
 
I purposefully got my id.3 to below zero.. after I had the battery recall (2 modules replaced) the range was messed up, so I did a complete file/drain and refill.. that meant driving around our local area until 2%, then slowly driving home and around the estate until it got very degraded performance and limped home and charged..

I ran out on the way to work, rolled to the main gate as lost power. Thankfully the off road team towed me onsite to a charger :cry:

Out of curiosity ............ did you have any grace period once the battery was down to zero. i know when the brown stuff really hits the fan 1st off power is cut and you are speed limited - been there once - and then finally all the screens and computer shuts down all bar legal features (never seen that and if i did i think i would be worried!)

but do you get much extra from zero or is that pretty much it? (there is a list of cars below (above) with range from indicated zero battery but the ipace is not there.

Thanks.
PS am not gonna hold you to it as an official Jaguar representative :D

I sent a grumbly reply to Octopus about the changes, and got a response from them:
I’m really sorry if this issue has caused you any stress, and I get why that part feels frustrating. The limit isn’t there to catch anyone out, it’s mainly to keep the 7p rate sustainable. Most people’s charges naturally fit within the 6 hours, but when a session needs longer the extra time pushes charging into periods when the grid is busier and power is more expensive. That’s why anything beyond the first 6 hours falls onto the Bump rate, even if the timing overlaps with the night window.

The aim is to give you as much of your charge as possible at the low rate while still keeping the tariff affordable for everyone. You’ll always be able to see your schedule in the app and adjust your target if it looks like it might run over. There will also be new settings coming soon so you can choose to strictly cap charging at 6 hours if you prefer.

I think the last sentence is pretty significant - this will alleviate any concerns I have.
 
No idea how this is going to work if your car is not linked to Octopus. My Ohme app charges all over the place in chunks. It’s meant to be linked to Octopus so maybe it will adjust itself. Going to add a fair whack to my charge cost if it’s only 6 hours a day at 7p I need 60kw a day.
