Charging Statistics

Is is possible to find how many kwh’s have been put into the car in the last day, week, month year etc

When you charge the car it takes takes more kW from the charger than the amount of kW that goes into the battery. This wastage is due to heat created by resistance in the cable and battery and (where relevant) converting AC to DC. The actual wastage varies according to speed of charging and local conditions like temperature.

For example, to charge a 69kW battery from 0 to 100%, the charger will use (and you will be billed for) about 80kW.

Even if the car kept a record of kW in (which I don't think it does), as it would be a meaningless figure as it would not be a true representation of the electricity that you hsp paid for and put in.

I actualky keep a record of every charge, including kW used on a spreadsheet. But then clearly Iam a bit of a nerd.

My charger (Zappi) allows me to find out how much charge has been supplied for a defined date period (max of 31 days). For public chargers I look at the receipts. As SP1959, I keep a spreadsheet, brothers in nerddom

Yes, my OHME also lets me know what I put in (not what the car received) on a daily, weekly or monthly basis.

The problem some will have is if they are slow charging from domestic plug sockets, they have no way of recording.

I use a cheap energy meter which my slow charging cable plugs into, to get the total kWh consumed at every charge. This value I then enter as litres of fuel in my fuel tracking app (Fuelly). I can then monitor energy consumption in kWh/100km.

Thank you for your guidance which I can do. I just thought the car’s software ought to be capable of recording battery charging

But then, ICE cars can't tell you how much petrol you have put in since you bought it either.
