As per @2StrokeDan's suggestion I'll use this thread to document the running cost of my Volvo EX30. I'll update here weekly.
Electricity cost R3.20/kWh, I charge up to 70% every time.
Notes
The solar charge column indicates that I charged the car from solar as soon as my house batteries were full, but to prevent depleting the house batteries I revert to Eskom once the solar panels no longer sustain the load. This way I keep the house batteries exclusively for house use.
As can be seen my car uses quite a bit more power than that of @Vintage_Mania and @dirtWarp. I must add I am measuring the energy with a separate energy meter, i.e. I am measuring the total energy used by the car to recharge - not just the energy that is put into the battery itself. I expect the efficiency to be >80% but this figure I'll be able to calculate once I start monitoring the car's own consumption figure (which I'll do henceforth). This means that up to roughly 20% of the charging costs are lost to heat, etc.
An interesting tidbit, ICE cars are roughly 35% efficient (this varies greatly but is basically never above 40%), which means that only about a third of the money spent on petrol actually propels the car. The rest is lost to heat, etc.
