Real fuel efficiency of an electric car? 165MPG


Trip counter on a car.

I've been driving EVs for a few years now - and people often ask me about running costs. I can't tell you what your insurance, maintenance, or leasing costs will be - but I can show you how much it costs to drive. Here's a fairly recent trip in my Renault Zoe: That's a mixture […] Read More

Renault's Secret Mileage API


Website showing my car and its mileage

Last year I reverse engineered Renault's Electric Car API. One of the curious omissions was mileage - it just doesn't appear there. However! All is not lost. If you log in to your Renault Account - https://www.renault.co.uk/my-account/my-car.html - you'll get details back about your car including its make, model, date of next service, and mileage! […] Read More

Reverse Engineering the Renault Zoe API


Last year I published details of the BMW i3's API. I've now swapped my i3 for a Renault Zoe - so I thought I'd perform the same exercise. ? 100%? 76 miles?

Twelve Thousand Miles in an Electric Car


I've spent an entire year driving the BMW i3 Electric Car. This is a long-ish term review which is intended to reflect my experience with the car and the UK's charging infrastructure. I spent three days a week commuting between Slough and Oxford, on a mix of motorways and quieter streets. I drove all the […] Read More

BMW and the GPL


I accidentally caused a little brouhaha last week - for which I would like to apologise. In my blog post about BMW's unencrypted software updates, I said: Judging from the files, it would appear that the infotainment system is made by Magneti Marelli with components by Wind River, AutoSAR, and Nvidia Tegra. Looking at the […] Read More

BMW are sending their software updates unencrypted


The BMW i3 is an amazing electric car - let down by very shoddy software. That's a huge problem - software runs our lives and, if it is defective, it can ruin us. We used to have separate categories of device: washing machines, VCRs, phones, cars, but now we just have computers in different cases. […] Read More

Drive the car, tuppence a mile!


(To the tune of the popular Mary Poppins song.) How much does it really cost to drive an electric car? Well, I've had my BMW i3 for a few months, so I thought I'd crunch the numbers. As part of the UK Government's OLEV scheme, there's a subsidy for installing car charging points at home. […] Read More

Reverse Engineering the BMW i3 API


I'm really enjoying driving the BMW i3. I'd love to have it tweet its driving efficiency, or upload its location to my server, or let me turn on its air-conditioning when the temperature gets too warm - there are a hundred interesting things to do with the car's data. The official app has some of […] Read More

Solar Charging Electric Cars


Regular readers will know that I have solar panels and an electric car. Is there any way to hook the panels up so they directly charge the car? Can I set my electrical system up to divert surplus electricity into the car when my house isn't using it. This is what I do with my […] Read More
