Re: [ocpp] Groups - CR Unit of Measure - Currency

ISO 4217 delineates current currency designators and some more information around currencies. A currency symbol can optional be used based on the used character set within EVSE firmware. For a quick overview see Wikipedia’s explanation at https://en.wikipedia.org/wiki/ISO_4217.

 

My recommendation is to use the ISO 4217 three character definitions.

 

 

Kind regards,

Thanks, Brendan. That's absolutely fine, as long as we have a means to denote the currency -- that's the more IMPORTANT factor.

Hi Rish, (All),

 

I believe that using any currency symbols would not be a good idea, as only two are covered by ASCIII/ANSI code tables, so it would drop us deep into obscure parts of Unicode, an when you take the world overall, new currencies and/or currency symbols are not that rare.

 

Whenever/however currencies are formally introduced into OCPP (as part of tariffing and pricing or otherwise), they should always be identified by the internationally standardized three letter upper-case currency codes (“USD”, “CAD”, “EUR” ,“GBP”, etc.).

Hi Rish, (All)

 

The current proposal is based on OCPP 1.6, DeviceModel and the discussion in LA.

 

Without tariffing & pricing and don't see a use case for things like: $/kWh. or even $ etc. 

 

So I would propose that the Tariffing & Pricing proposal will have to add units that are fitting/needed.

 

Complexity with adding things like: dollar, euro... then we will need to add them all. Which ofcourse can be done... 

I dont know the correct IETF/ISO/IEC standard, have to google it, but we should reference that specification in OCPP 2.0 IF we need a currency unit..

Kind regards,
Robert de Leeuw

As discussed, unit for "currency" is missing -- most of the dynamic pricing tariffs represent price of power and energy, for example, as, $/kWh or $/kW. Also, in certain instances "multiples" are used -- e.g., 2x, 4x, etc. that are indicative of the additional prices on top of the "normal" or "base" price that are determined between the utility and consumer.
