How To Set Up Eichrecht in EVC-net

As a CPO, you can use the EVC-net platform in your charging infrastructure to become Eichrecht compliant. 

In order for Eichrecht to work with EVC-net, the public key needs to be filled in the channel information of a charge point. 

Then, the Eicherecht compliant charge station digitally signs and encrypts the measurement data before sending it to EVC-net via OCPP. EVC-net stores this data and makes it visible in the transaction details for end-users.
