The introduction of public charging points on a global scale means that at present there is not a globally recognised callibration standard, but calibration is currently implemented on a national basis. In the UK this is currently enforced through the Measuring Instruments Regulation, but this is a more general piece of legislation which does not specifically tackle public charge points. However, the UK government are making strides to protect consumers, having introduced the Electric Vehicles (Smart Charge Points) Regulations 2021 www.legislation.gov.uk/uksi/2021/1467/contents/made and the Public Charge Point Regulations 2023 www.legislation.gov.uk/ukdsi/2023/9780348249873 is in the process of progressing through Parliament, although of course this has been delayed due to the General Election.
