How Low Can You Go .... (SoC)

[siteguru]

It's GOM calibration and balance time, so I ran the car down low and left it for a couple of hours before starting to charge. This was a photo I took immediately before starting the charge:

Anyone else gone lower?

PS - I checked the SOH with Car Scanner and it said 92.66%. I'll check again once charging and balancing is all done.

 

[Diggsy]

Do you do this from your own data? I’ve never let the car run below about 5%, and just charge it to 100% as and when I need it, which is usually twice a week, and usually from 50-60%.

 

[ReintjeWA]

2% would definitely leave a crease in the seat fabric for me

I could probably get to two% driving round the estate, but I would want to be coming from very far.

That's what I was doing, pretty much. I went for a drive around, and finally to the nearby village and back ... the uphill stretch coming back from the village had my buttocks clenching when the power started to limit ....... I made it home OK though

My lowest so far is 5% and that had me a bit worried. I tend to charge now at about 20% but certainly no lower than 10%
S'pose it similar to driving on fumes in an ICE car, looking for a garage. Although I can imagine it would be a bigger pain in the Ass. To to run out of charge in an EV.
Than to run out of fuel in an ICE car.

Less of a pain than running out of diesel in a vehicle that needs bleeding.

You could always carry an eco-flow (or similar) like Bjorn does in his range tests to recharge.

Or, better still, just post a "yelp-for-help" on this forum and I bet someone would get you going with their MG4 and V2L lead

Do modern Diesels need bleeding?
Anyway, EV or ICE it would be be a Pain.
Out of curiosity, has anyone run out of charge. What did you do?

Probably not, I'm just old and memories of a 1980's Peugeot diesel come flooding back

Nope not like they used to with a priming bulb and mechanical injectors. Fuel is constantly pumped and circulated in the common rail which feeds the injectors. Interestingly that’s why you should keep the tank with a decent amount of fuel in as it needs to lose the heat in the return to the tank.

Reminded me of the Ford focus I ran a decade ago, I had a gizmo wired in-line with the common rail pressure sensor which 'tricked' it into running higher pressure thus giving more power.

Fine for a good couple of years until one rainy January evening at 60 mph I heard a faint 'ping' and the engine died immediately thereafter. Flat bed recovery after waiting 2 hrs freezing to death

After much head scratching investigation, turns out that there was a tiny hairline crack in the cast metal common rail itself, clearly had enough of the increased psi after 24 months of abuse.

Regarding the 4 SE, I've ran mine to 0% and it still moved for a further mile before I scuttled for home and charger, just wondered what happens at zero

I’m pretty sure RAC here in Perth has one or two EV-rescue vehicles that basically carry a (fast?)charger with them in the van and can charge you road side, but I don’t know what happens if you’re out of the city. Maybe they send out a truck with a generator?

I always have my granny charger with me, if it ever came to it I would just find myself a house and offer them some cash to charge for a few hours. Not great but better than nothing.

PlugShare shows you some private chargers too come to think of it, that would be better than a granny charge.

I never let mine go below 25%, our nearest hospital and emergency on duty vets are 30 km away and , you never know?

Unless you know someone nearby who has a 50% charged car with V2L, and you have time to spare. An hour would give you around 3% which may be all you need to limp home.

Good point.

Nop. When my diesel Merc goes into 'Reserve' amount of fuel I still have 108 miles of range left .......

The luxury I must admit I miss from ICE, doubt batteries will ever compete with the energy density of liquid fuel in my lifetime.
Pretty much all I miss though

Our UK lot have whacked big alternators into some of their recovery vans so they can up their idle and pop a little charge in to limp people to a charger.

Bear in mind that running out of 'fuel' can result in a driving offence with a fine and penalty points depending on the road conditions. Busy road, motorway, dangerous conditions etc.

My lowest so far is 3%, so I could do a balance charge, normally hold it at around 35-70%.
