So, one of the things I like about owning a Nissan Leaf is that I have the ability to check on my car’s state of charge remotely, ensuring I know if someone unplugs it, or something goes wrong while charging.
I can also check and see how many miles of estimated range I’ve got, so if I only need enough to get home I don’t have to wait for a full charge before leaving.
The Twizy doesn’t have this facility, but thanks to the Open Vehicles project, it’s possible to add this function as an aftermarket hobbyist extra.
Behold the OVMS!
Support for the Twizy is certainly well behind that for the Tesla Roadster (which is what the project originally started on). However, there’s some great strides going on thanks to hard work from the open source community, and you can now plug your Twizy into the system reasonably easily if you’re geeky enough!
I’m currently sans Twizy, but I’m hoping that my replacement car will be on its way soon and then I’ll start to play.
IN terms of cost, the unit and the necessary cables costs about £100 all-in. On top of that, you need to buy a SIM card that will take care of the data and text messages the system needs to communicate with the outside world. You can then either opt to use SMS only, or to go through the OVMS server (which is free).
Another nice feature is that it adds GPS to your car. Not in terms of road routing, but in terms of location. It makes it easy to find out where your car is (if you forget where you parked it) or if you have the misfortune of having it stolen.
