However, if you want to avoid being locked into a single platform, an OCPP-enabled EV charger is worth considering.<\/p>\n\n\n\n<h3 id=\"check-whether-the-ocpp-version-is-compatible-with-your-csms\" class=\"wp-block-heading\">Check Whether the OCPP Version Is Compatible with Your CSMS<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cSupports OCPP\u201d does not necessarily mean that the charger is compatible with every CSMS. Before purchasing, provide the manufacturer with temporary access to your CSMS for testing. Actual connection testing is more effective than reviewing documentation alone in identifying compatibility issues.<\/p>\n\n\n\n<h3 id=\"confirm-the-ocpp-testing-and-certification-status\" class=\"wp-block-heading\">Confirm the OCPP Testing and Certification Status<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">OCPP support is generally verified through manufacturer self-testing, third-party laboratory testing, or OCA certification. Manufacturer self-testing is usually sufficient for standard projects. If the project has specific compliance requirements, third-party testing or official OCA certification may be required.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 id=\"ocpp-faq\" class=\"wp-block-heading special-title\">OCPP FAQ <\/h2>\n\n\n\n<h3 id=\"can-i-mix-ocpp-1-6-and-2-0-1-chargers-on-the-same-network\" class=\"wp-block-heading\">Can I mix OCPP 1.6 and 2.0.1 chargers on the same network?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, but your CSMS must support both protocols simultaneously. Most modern management platforms handle mixed fleets. Plan your migration toward 2.0.1 or 2.1 for new installations \u2014 1.6 is adequate for legacy hardware but increasingly excluded from public tenders referencing IEC 63584.<\/p>\n\n\n\n<h3 id=\"is-ocpp-certification-mandatory-in-europe\" class=\"wp-block-heading\">Is OCPP certification mandatory in Europe?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Not universally \u2014 but practically yes. The EU&#8217;s Alternative Fuels Infrastructure Regulation (AFIR) mandates interoperability, and OCPP certification is the recognized proof. Germany&#8217;s Eichrecht requires calibrated metering. France&#8217;s AFIR decree explicitly references OCA-certified equipment. Without certification, you&#8217;re locked out of most public funding and roaming agreements.<\/p>\n\n\n\n<h3 id=\"can-ocpp-1-6-be-upgraded-to-a-higher-version\" class=\"wp-block-heading\">Can OCPP 1.6 be upgraded to a higher version?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">OCPP 1.6 systems can be upgraded to newer versions like OCPP 2.0.1, but it depends on the charger hardware and firmware support.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Need help selecting OCPP-certified hardware for your European deployment?
