Apparently everyone else knew it was coming and it was on the news, but I don't watch the news!
I had a wee panic because I'd deliberately not plugged the car in the previous night as it was still at 70% after yesterdays commute and I wanted to run the battery down a bit to trigger a cell re-balance, but I suddenly realised that was a bit of a foolish thing to do when you can't predict what might go wrong the next day, eg snow and ice, traffic accidents causing traffic jams and so on. So I quickly plugged it in and in the hour that it took me to get ready the RR went up from 44 miles to 54 miles - so it looks like it charges at about 10 miles range per hour at 10 amps from a 230v socket. (16 miles per hour on a Type 2 charger then, as that is 16 amps)
The car itself worked fine in the conditions, the traction control was a bit odd on very slippery surfaces - when I'd initially try to accelerate I could hear one of the rear wheels slipping and pulsing on and off, sounding exactly as if ABS was activating - it looks like as well as limiting torque the traction control can independently apply the rear left or right brake to help in cases where one wheel has lost traction - a poor mans limited slip diff. I believe Tesla's do the same thing - they also have fully open diffs, but will selectively apply the brake on a slipping wheel at slow speeds to allow some torque to reach the wheel which does have grip.
If I gave it too much throttle it would initially try to spin the rear wheels but after a second or two it would settle down and pull away smoothly - it seems like when it detects a lot of wheel spin from a stationary start that it goes into a kind of limited torque snow mode automatically and stays in that mode for a while, as I noticed acceleration was cut significantly.
The tyres are dunlops and judging by their performance in the snow they're summer tyres! The regenerative braking slowed me very well in the snow without any skidding but I found that applying the friction brake was triggering the ABS on the front wheels quite easily - possibly a consequence of the much narrower tyres on the front where most of the friction braking is applied, vs the wider tyres on the rear where the regenerative braking is applied!
The roads were complete blizzard conditions with traffic jams galore. I needed to use the heater and A/C a bit to keep the window clear so after an 8 mile journey (most of it hardly moving due to the traffic jam) I'd used 14 miles of range. Ouch! So sitting in nearly stationary traffic with your heater running is a sure fire way to chew through the battery...
I think the next EV I buy will definitely be one with a heat pump heater and a pre-heating option!
Yes Diagbox works fine and lets me do all the dealer diagnostic stuff.CitroJim wrote:Good to know Diagbox/Lexia talks to it Simon, even if not 100% fluently it's still a good help...
I'm sure our friends out in the Far east will soon make a suitable dongle readily available at an affordable cost
Suitable Bluetooth OBD-II dongles that are compatible with both Canion and EVBatMon seem to be available for about $50 US which is not bad at all. I'd buy one if I had an Android phone or Tablet to run the software but I don't, so I'd have to buy an Android tablet as well! So not going to happen just at the moment as we have to pull our socks up for the next couple of months...
The slabs are a bit of a pain to be honest as they haven't been laid very well so they move around a bit and nothing is level so any jobs that need level ground (like checking gearbox oil) can't be done. I had to fix a few rocking slabs last summer to bed them down and level them properly but one of them is rocking again, presumably some of the dirt underneath has washed away.lexi wrote:That is a nice bit of room you have off road at your new house Simon? Good for jacking and spannering on the slabs.
These leccy cars are very interesting and I knew nothing about them till all this on here. You must be quite excited and new fangled with it Simon. I think I would have went out for my "free charge" as well.
Yes the electric car is a fun new toy - I like the fact that it's a toe in the water so I can get some real world experience and use of a cheap EV, but I still have the other car as a backup as well. So I can experiment with what the "limits" of the car are in real world conditions, and find what it can and can't do.
