Local is best

Over the past week we’ve just been doing local driving, probably no further than about 10 miles on any one journey and and generally on slower roads with speed limits upto 60mph.

We have found that the efficiency of the car improves greatly, most trips have done between 3.7 and 4.2 miles per kwh, based on that, and the battery size of 71.4kwh means we should reach Toyota’s range range figure of 270.92 miles, in theory if driving local we could get a range between 264 and 299 miles.

This is not a scientific or 100% accurate calculation, but a full charge if starting on 0% (which  you would never do) up to 100% it would cost about £5.35 to charge on the Octopus Intelligent go tariff based on  off peak current price of 7.5 pence/kwh.  At the moment the current price of unleaded petrol is £6.50 a gallon and in my Toyota Rav4 2.5 litre self charging Hybrid I was getting about 40 mpg, so the cost of 280 miles would cost around £45.

So for  local driving and being able to charge at home is a saving of around £40 per 280 miles.

Remember in my post Just back from a 320 mile round trip I was driving faster and had to charge at a rapid charge so the savings are far lower. After a quick google it is suggested that the most efficient speed for an EV on average is 50-60mph, the next time we do a decent journey like the one we did in the above post I will reduce my speed to see how much it effects the range and costs.

Just back from a 320 mile round trip

OK in the UK it is Mothering Sunday tomorrow so yesterday we drove to see my mum, it’s about 160 miles each way. Thursday afternoon we charged the car to 100%, it was on about 65% before we plugged it in and as we are not on an EV specific tariff yet it cost us about £7 GBP. Yesterday we switched to an EV specific tariff. This morning I got an email saying we have been switched over (same Energy provider, just changed tariff) which should cut the cost of home charging by 75% but must remember the cost at other times are higher than the normal tariffs.

So we drove to see my mum yesterday, the drive was good, the car  went well, and we planned to stop at Cambridge Services on the A14 to top up the car, we normally stop here for 10-15 minutes anyway. When we pulled in there was a couple of free chargers but the BZ4X still had 54% battery left and we was only about 60 miles from our destination so we thought we could easily make it without charging. Toyota claim that the BZ4X can do just over 300 miles, we had done about 100 miles and used about 45% so we’re not going to get the 300 miles on a charge, but should easily manage the remaining 60 miles.

We decided to stop at a Gridserve Electric Forecourt which has a 36 chargers of various speeds. The car was down to 17% but we had been stuck in traffic for a while and for the whole journey I was doing 80-85 mph. Using the forecourt was easy, plugged in, used my contactless card and then went into the Costa for a cofffee and cake, 25 minutes later we had charged upto 80% at a cost of about £33 GBP so off we went to see mum.

This afternoon it was time to head home, made the mistake of thinking we could top up at the Gridserve site before heading home. Again plugged in and went for a coffee again, after 20 minutes checked my app and notice the BZ4X had only increased by 4%. Not happy but then realised it was my fault as the car was 0n 77% before plugging in and once you are charged to 80% the charging slows right down, just like many phones etc. So off we went on our journey home. We decided to stick to 70mph for the return journey, to see what effect the reduced speed would have on the range of the car.

Again we planned to stop at the Cambridge Services but decided not to as it looked like we had plenty of charge left in the car. Nice drive, I should note we don’t use air con normally, no matter how the car is powered, we tend to open windows instead. We didn’t stop at all on the way home but we took a big risk, we got home with 7% battery power left. so even though we had lights on as it was getting dark, we used 73% of battery for the return trip compared with 83% for the trip yesterday, so reducing my speed by 10% increased the range by at least 10%, probably a bit more as I didn’t have lights on (apart from day lights) going down.

We will charge the car tonight with our home charger, lets hope our electricity tariff has been switched so overnight charge should cost me about £5 if my maths are right. In which case total cost of trip will be £37 compared to about £70 it used to cost me in the Hybrid 2.5litre RAV we had before.

Playing with our new EV

Apart from doing a few miles each day for work we haven’t really done much driving in out new Toyota BZ4X EV but instead have spent a few minutes here and there checking out some of the features.

The car has all the standard bits you would expect, air con etc but we went for the top Vision trim front wheel drive and we wanted to play.

It comes with an automatic boot, ie kick your leg under the rear to open the hatch, well that turns out you virtually have to bang your shin against the rear bumper in the right spot for it to open, can’t see us using that too often on a shopping trip as our shins are going to be black and blue. The car not only has heated steering wheel and front seats it also has ventilated front seats which apparently cool the seat in hot weather. Being as it’s only March and we are in the UK we have not got around to testing this out yet.

One thing that has really bugged me over the last couple of days is the multimedia system. It has the option to create driver profiles. So when driver a gets in, it turns the radio to their selected station etc, when driver b gets in the radio station is set to their favourite. As there are two of us that will regularly be driving the car this sounds great. Setting up the driver profile you can add their phone to their profile as the prefered bluetooth device as well as a key fob. As for some strange reason Toyota only sends out one key fob with the car and then a second is apparently sent out a few weeks later we didn’t think we would add the key fob to the driver profiles just yet, assuming the system would detect which phone is connected to decide which driver is in the vehicle.

OK so my details had already been added by the dealersip, so we wanted to add my wife as a seperate driver profile. well that isn’t as easy as you would think. First of all do a quick google and toyota.com states the ‘owner’ as to ‘add a driver’ from within the Toyota app on their phone and that then invites that person to install the app on their phone, well it turns out that is not the case in the UK. You can’t add a 2nd driver that way, although both the dealers and toyota UK social media team thought there must be a a way.

We then decided to install the app manually on my wifes phone and create her her own my toyota account. Simple, now get in the car and set up her profile. worked fine. However next time one of use got in the car we had to agree to terms and conditions and then we was logged in as ‘Guest’, we then had to scan a qr code from the app on our phone to log in as the driver profile. Sorry but this is going to be a right pain in the back side every time.

I also noticed that if my wife drives the car and parks up, if I then check the ‘find my car’ in the My Toyota app, it doesn’t find it. Not helpful at all.

So as a last resort we added the one key fob we currently have to my profile, hey that worked, i can get in and out of the car without logging in everytime. So at the moment having two profiles is pointless as we have just the one fob and to the wife’s annoyance, when she is driving she has to be logged in as me. It’s a minor thing but one that does niggle.

Once the 2nd fob arrives we will register it against the wifes driver profile and see if everything works as you would expect but to be honest I am not holding my breath, it just doesn’t feel like it will work for some reason.

Apart from that, we are happy with the car so far, tonight we will be charging it to 100% as we are going on a long journey tomorrow.

Collecting our new EV

This afternoon we collected our new and first ever EV, a Toyota BZ4X in Scarlett Red.

The car before it was prepped for us to collect

For the last 4 years we have had the Toyota Rav4 Hybrid and hadn’t been sure if we was ready to go full EV but after watching a couple of things on TV and a bit of googling we decided to give it ago.

Everyone knows if you google EV reviews etc, for every one that loves their EV, there is someone else who slags them off so we thought unless we try one ourselves we will never know how good or bad they are or if they are the right fit for us, and as we lease our cars for 3 or 4 years, if we don’t like it, we are not stuck with it forever.

This blog is not going to be updated on a daily basis as generally most of the driving we do is local, with the occassional long journey once a month of about 320 miles return trip, which we are doing this weekend as it happens.
