EV general discussion

I realised I hadn’t done a charge to 100% in many months which means the cells would need balanced. It’s obviously not a complicated process, just charge to 100% every month or two.

Charged my 77kWh Born to 100%, left it for a few hours and then drove for 15 miles. The SoC dropped 11% over just 15 miles, which is obviously concerning. So I charged to 100% again and did the same trip. This time it dropped 5% for the same distance and the GoM recorded much better efficiency.

So if you are doing the 80% rule, don’t forget to do a 100% charge now and again to balance the cells.

Battery SoH is reported as 96% on car scanner app and that was at 14c for the battery. Not bad for a 2 year 8 month old EV with 25300 miles on it.
 
It kinda makes me sad that the youth of today/tomorrow will never experience that mechanical connection with a car.
I guess it's called progress :(
I reckon the same was said about the connection between a person and their horses when then the motorised carriage first came along, again in the sake of progress. I am personally all for the world slowing down, we try to do everything too fast with no consideration for where we are headed a lot of the time. Personal feelings aside there are some great advantages once we finally get 'new' cars working in harmony with the rest of humanities needs, making them an even more important tool.
Yes, and the half the problem with that is they have no attachment and treat them as such, ie very badly, and spend as little as possible on maintaining them to the point of the car being a death trap.
I'd hope as car become more simple this is less possible and cars are harder for people abuse, no idea why people buy ditch finder tyres though that boggles the mind. My neighbours 2003 Fiesta has just been taken away sadly for her, serviced and MOT'd every year by our families garage, all that was wrong it it was a bit of rust and clutch started slipping a bit last year. I am not sure what you can do about people not caring about driving a death trap other than put more punitive measures on failures or make older cars have more checks more often.

Wasnt aware of this, thanks. Had my renault 5 3 months and only charged to 80%.



I've been averaging 3.9mpkwh normal driving with heating/ac. In eco its over 5mpkwh. Decent figures?

Are cars really becoming more simple though?

This is something that often gets said about EVs because they have less oily moving bits but almost all modern cars are far from simple.

If the chancellor gave me a BIK incentive the cost/benefit equation would be simpler
.... if you won the pools and had to choose one daily commuter in summertime, what would it be. ?
The pools ?? Welcome to 1989

Don’t understand the BIK comment. It’s not a company car ?

The list of "ifs and buts" you have for not owning an EV yet must be becoming quite the War and Peace!
Works be easier if he just boiled it down to a couple of things like most people do, he is scared of change and a cheap skate. ;)
 
Just seen a deal on HUKD for Masterplug EV granny charger, 5 meters for £91 from the rainforest.
 
That is the single reason most people do go for an EV.
I'd literally be crying driving into the office right now if we hadn't switched the household away from petrol :cry: An extra £75 a month at current prices, on an already substantial fuel bill would not have been fun.

The 200 mile round trip to my parents for my little ones birthday this weekend would certainly have been cancelled, the same trip again over Easter for her to spend time there and me to go to the rugby with friends again would have been cancelled.

The part of the car that moves you from A to B has gotten simple on EVs, but the complexity has been added into so many other areas such as ADAS, infotainment, AI "helper" etc. Many modern cars are described by their manufacturers as software defined vehicles.

As in maintaining yes, I’d say so.
There’s not a whole load to repair on an EV when it goes belly up, and to be fair even on ICE how many garages actually repair anything these days.
Cars now are just a collection of bits that bolt together and get lobbed away when faulty rather than be repaired (engines, gearboxes, starters, alternators etc).
At least with an EV if you don’t service it for a couple of years it’s unlikely to cause a problem.

Yeah and I guess that is the point that Journey was making. You can't 'neglect' it in the same way and have lasting consequences.

With the exception of the motor I must admit EVs seem incredibly complex to me! While I get the concept, the precision of the inverter to take 400/800V DC and turn it into a 3-phase AC source to drive the motor, with the exact required amount of torque, still seems like black magic to me. I mean, modern fuel injection isn't exactly simple but I can at least break it down to an over simplified bigger squirt = bigger bang equation!

Inverter failures seem rare though so those electronics must be pretty robust.
