The strange thing is the meter records usage when the car isn't being
charged.(i.e.) last week after recharging the meter read 73.65kWh. This
morning when going to recharge the car again the meter read 74.16kWh so
where did the 0.51kW go ?

Was the car charger plugged into the meter? Does said charger have a
physical on/off switch, that breaks the circut? Was that in the on or
off position? Or does it have a "soft" power switch that just
electronically switches the device "off". Or no power switch at all?

3W could easyly be the "standby" power consumption of the charger, in
anything other than phyiscally switched off.

I've recently got one of those type of power meters. With it plugged
in and powered up but nothing plugged into it it shows zero power.
What does yours show? What does it show with the chrager in and "on"?
