I need to contest.
On your energy bill you pay the “kWh” of energy you consumed per year. Thats correct so far.
The actual sheet for energy rating does not show the used energy anymore. Now it shows the EEI (energy efficiency index)
Also on the label is shown: “the energy consumption in kW·h /cycle”
That means basically the used “kW” times hours as you correctly point out.
But what does it mean?
Example: If our machine consumes 2 kW per cycle within one hour, the energy rating would be very bad. But if it consumes the 2 kW within 3 hours, the energy rating suddenly is much better. And this is how the energy rating works.
For the consumer it doesen’t matter in which time the consumption happens. The consumer needs to pay the used kWh.
So I do not see any improvement to implement the cycle time in the EEI. The consumption per cycle is what matters.
Totally agree.
