Power Pack to Jump Start Car

If it has 160 miles range, and was used 110 miles a day, why wouldn't it have been charged overnight on a home charger?

(assuming the driver lived somewhere with a home charger, of course - something we can't know without asking them)

Theo

Because there would have been days when the mileage was over 110 miles, amd the driver(s) would want to pick up premium fares at night.

Is there an industry-wide meaning to SOH, or is it just a number, should it be a linear decline?

I got the NOCO Boost GBX55, the smaller one was showing later delivery. Arrived yesterday, took a few hours to charge (I may look for a more powerful USB charger) but started the car on the second push this morning. I immediately took the car for a 15 mile drive and the battery is now charging normally on the trickle charger.

When I connected the booster it took a few seconds then there was some clicking as all the electrics (presumably responsible for draining the battery) came back to life.

It is now asking for a PIN for the radio, supposed to be in one of the booklets.

Once it was clear what was needed the hardest part was finding the bonnet catch, I had to go online to find out where it is, followed by how to get the physical key out of the fob as there was insufficient power to respond to the signal.

Many thanks for all the input, recall work and new battery to be done soon as I can get an appointment :-)

Petrol is currently 132-135p per litre in East Anglia.

My domestic electricity is 26p/kWh, it could perhaps be less if my smart meter worked, but it's more than two years now since it broke and I can't get any traction for requests to repair/replace it.

The meaning is the percentage of usable battery capacity remaining from the original. eg if the battery was 100kWh (usable), a 91% SoH means only 91kWh of that remains usable - if you charge to full you'll only get 91kWh out of it.

It's just the same calculation as the SoH in laptops or phones, although it's common for cars to have some buffer at the top end to avoid overstressing the cells (for longevity the installed battery might be actually 105kWh but they only ever charge to 100kWh even when new)

Exactly how that is calculated is down to the BMS in the vehicle. Decline is down to the chemistry, but typically it's common to lose a few percent in the first year or two and then flatten off. Some of those percent can be masked by the buffer, depending on how they calculate it (eg if the battery is really only 102kWh now, it still shows 100% SoH because the usable capacity remains 100kWh).

Well, they have a 160 mile 'tank', so doing over 110 is no problem. It depends what kind of taxi they are - you wouldn't use that one for 200 mile airport runs, but for a central London minicab with 20mph speed limits everywhere 160 miles equates to 8 hours constantly doing the speed limit.

Some of the EV tariffs allow you to get discount rates at any time, not just the middle of the night. But also many taxi drivers don't work night shifts.

I agree it's probably not been driven 7 days a week, but a short topup during lunch/etc means that longer journeys can be done but still most of the charge can be from overnight.

That is impressive. Even average mileage 5 year MG ZSs go for well under £10k.

Had a lift in one a few month's back. Very comfy and refined. Interior rather plasticky, and touch screen everything well beyond me. And the heater didn't seem to do a great deal, even when set to 23C.

It's not often that someone makes me feel young these days. Thanks guys!

(and yes, I know 5/- is 12.5p...)

Andy

It depends.

I do about 2000 miles a year in my car; my wife's is around the 10k mark (we have no idea which of us does those miles)

The cost of capital for an electric car does not make sense for mine. It might for her, and I am suggesting she should think about for her next car - she wouldn't need long range. I'd probably have to get something sensible instead of my aged sports car.

One of our sons does 20,000 miles a year. For him there is no question but that electric is cheaper.

Andy

Really? 5/- = a quarter of £1 = 25p

We've had an electric car for a bit over 2 years now and it is used almost exclusively, although we do have a petrol car for holidays where charging may be problematic and long trips (especially if we get an urgent family emergency in Ireland). However, the petrol car is doing so few miles, that we are going to give that to our eldest son, when he passes his test and its replacement, for our purposes, will be my 58 year old Land Rover ... as fuel costs for the low mileage are pretty immaterial.

OK, I don't remember the difference between half a crown and a crown any more.
