EV Charging Station - feature request

Hi,

I'm working on review of EV Charging Station for my YT channel - the first one with lcd, and to be honest... it's not the best victron product that i've seen.

Nevertheless I have small feature request that will improve the readings of power - if you have connection with cerbo, could you add voltage reading from cerbo? You already have those values in the system so it seems to be very easy to add that feature. Without this showing the charging power it's completly useless with this const power calibration parameter. Voltage in the system fluctuates... especially if you use power from the grid... in a sunny day here in Poland it could be 20V more than during the night. So 20V multiply by 16A and multiply by 3 phase it will give us almost 1kV of misreading ;(

@Lucian Popescu (Victron Energy Staff) - is it possible for you to add this kind off power calculation?

While a nice to have, apart fropm us techy people here in this forum, I don't think the average user has use for that. Besides, if you need the voltage, you have it on your Grid info in VRM. For off grid, it should remain a stable 230V or 240V per phase depending on where you are in the world. You don't have your accross phase voltage either (380V/400V/415V) but it's not really an issue, as long as it's within values, is it?

Hi, the charging station was not designed to be a measurement device. At least not this hardware design. I agree, it should be better to have the voltage measurement added for more precise calculations.
I can give you an inside info, next version will have it, and many other cool features. Don't ask me when, I can't give you that answer :).

Yest I did. But the calibration uses constant value... and the voltage fluctuates during the day.. so it is useless ;( It should be done using real voltage values rather than constant value. Like I said before.. you have all the data that you need to do it. It's a simple programming solution... so I really don't know what is the problem to add that kind of feature?
