You can use an OBD2 dongle to precisely know exactly how much juice made it into the battery. And an app to record that information.Is there any app or device that we can use to keep track of how many kWh we put into the MG4 ?
This doesn't account for losses in the car as it will only show what's in the pack not what's lost at the conversion point in the obc( End% - Start% ) x Usable Capacity ??
e.g. ( 100% - 40% ) x 50.8 = 30.48kWh
Where as an electrical engineer I'd take it to be what was actually put into the car not what it storedThe OP is asking about kWh put into the car. By that I assume they mean kWh put in the battery ... that calculation does exactly that (within bounds of tolerance).
Total kWh delivered from the supply should usually be obtainable via the charge point app. Thus overall efficiency can be calculated ... ( Power Stored / Power Delivered ) x 100%
Another option if you use a granny charger like myself is to use a smart plug with power monitoring. I got the idea from other users on this very forum.Is there any app or device that we can use to keep track of how many kWh we put into the MG4 ?
I guess I'm not understanding you - my reply above covers both aspects as far as I can see? Energy Delivered (what's put in the car*) vs Energy Stored (what's put in the battery).Where as an electrical engineer I'd take it to be what was actually put into the car not what it stored
Theres a difference to what is put into the car which is the total power transferred from the supply to the car.I guess I'm not understanding you - my reply above covers both aspects as far as I can see? Energy Delivered (what's put in the car) vs Energy Stored (what's put in the battery).
But that isn't what you originally stated in post 4, which is where I said that doesn't take into account losses, and then in post 7 you added that you took it to be only what was stored is what you believed he meant and I said I'd take it to be the total power used as an electrical engineer.Exactly ... and that's what post #7 covers.![]()
