Anybody have a BMW Active Tourer Hybrid?

TanDiy

I know it is a bit cheeky but just looking for anybody with a BMW Active Tourer who I could trouble with a couple of questions that BMW seem unable to answer. Thank you.

Just ask the questions.

(1) How much does it cost to charge the batteries from flat - how much electricity?

(2) Does the car allow the batteries to go completely flat? One dealer said that the car will always maintain a base charge so that the car has the extra power for overtaking when needed. Another dealer said the batteries just go flat and you will be running on the petrol engine. BMW online said there was a separate arrangement so that extra power could still be delivered from the batteries even when they were shown as flat.

(3) When switching to Save Mode so that you are running on the petrol engine and charging the batteries, what MPG do you get.

Thanks.

Probably worth mentioning you asking about the 225xe plug-in hybrid?

But since this is a new model there are probably few owners around.

Its probably similar to my Outlander PHEV hybrid,

1. so look up how big the battery is in kWh (kilo Watt hours). It depends on what electricity tariff your on but typically it will be about 10p per kWh. So a 10kWh battery will (no surprise!) need 10kWh's to fill it. So 10 x 10p = £1

2. It won't allow the battery to go completely flat, as the dealer said it keeps a reserve for acceleration, but more importantly it avoids damaging the battery by deep discharge state ..and needs to keep enough to power the starter for the petrol engine. In my Outlander it keeps back about 20% so in practice only uses 10kw of its 12kw battery.

3. Dunno for your car. In any hybrid its very dependent on driving style, more so than diesel cars. Staying relaxed, my 2 ton 4 wheel drive hybrid can just do 40mpg in save mode. I would hope you manage better in yours.

Better allow for losses in the charger. I don't know what they are but probably greater than 25 percent.

Answer to number 1 is easy to answer theoretically, if not practically - sillygoose has got it right. My Renault Zoe has a 22kWh battery. 1 kWh of electric costs me 13.6p - therefore it would cost me £2.99 to charge it. That's about as accurate as you can get. It doesn't allow for inefficiencies in the charger, but I wouldn't worry about that.
speakev forum will be a good place to find the answers to these specifics.

How are you finding the range on your Zoe now that you have owned it for a decent length of time?

Good. No reliability problems or range surprises. A couple of broken chargers encountered but I think we've got an excellent infrastructure in NI (and RoI). Got it in November, so I've been through winter and getting into summer. The surprising thing is just how much of an effect the temperature has on range. I knew it would be better in the summer, but I'm looking at almost 1.5x the range. Roughly 60 miles in winter and 90 in summer is a good GENERAL GUIDE.
I commute in it and have a regular journey - 10 miles, some stop/start, and generally not getting about 50 mph. People will say that in the winter the heating, rear heated windows, lights, wipers are used more and will take power - this is wrong IMO - it's a small amount compared to the amount of energy to provide MOTION. I'm happier to run air con in summer than the heating in the winter!
And the last caveat, which all drivers should know, is that driving 10mph faster is disproportionately expensive to range - you don't notice it so much in a petrol/diesel, but doing 60 instead of 70 really does get you a lot further in an electric car. Speed is absolutely not a problem, as long as you've got the energy!

Thanks for all the info.
