Charging battery from mains is series with a capacitor

I'm sorry I missed Your post, my bad.
But Its not a down-step of the voltage, its a power-factor shifter and current-limiter.

If you limit the current, then under load the voltage is going to be lower.

In George Wiesman's own words from his doc:

The CBC uses capacitors instead of a transformer to change highvoltage into low voltage.

Hob,

Evidently your power meter can not be trusted.

So use your scope to measure the grid power. That means you'll need to insert a CSR and use a probe to measure the grid voltage and one to measure the grid current.

Then do similar by measuring the voltage across the FWBR (AC side) and combined with the CSR you can determine the power going into your charging circuitry. Then compare the two.

Are you willing/capable of doing this?

Let me know if you want me to draw it out for you.

I'll do that (and more) but not right now, has to be when there are no guests in the house so I dont get distracted.
As a matter of fact I has to go now to attend to dear distractions ;-)
