Last autumn we bought an all electric car. In January this year I changed the usage options on my OVO to include electric car charging. I have had a Pod Point charging port installed. In Scotland, charging at most public charging stations are (currently) still free so we rarely use the home charging. Last time I charged the car at home was in March about 20m worth. The usage graph regularly shows my electric car usage at over 10% of my total usage. There must be some issue with OVO algorithm. Has anyone else got an electric car and home charging station, what's your experience with usage graph?

The usage projection in the OVO website is mostly based on guesswork, based on your usage throughout the day -- it sees a certain amount of power being pulled at different times of the day and tries to guess what you might be doing around the house.
I wouldn't try to rely on this as accurate information. If you want more accurate usage information, your best bet is to find out if your charger manufacturer has an app as this will provide very accurate usage info. PodPoint and ChargedEV chargers provide an app that will do this, and I'm sure other manufacturers do too.
Failing that, you can buy a Power Monitor on Amazon (make sure you use one that reads from a CT clamp, not a plug socket), and you can put the clamp around the cable going to your charger to make your own custom power meter for your charger -- no wiring required.
