Don't fall into the trap again! Choosing the wrong OCPP version for your home charging station's mainboard will cost double in future upgrades!

1. The Current Reality of OCPP Versions in the European Standard Market

Current Landscape (2024-2025)

• OCPP 1.6J: Dominant in stock, with mature compatibility across operator platforms, but limited functional ceiling;

• OCPP 2.0.1: Incremental enforcement, driven by EU AFIR, Germany Eichrecht, and France ANSSI;

• Transition period: Most platforms support dual stacks, but the 2.0.1 features take precedence, with 1.6J gradually being phased out.

Trends after 2026

• New Installation Mandatory 2.0.1: Legislation in multiple EU countries prohibits the connection of 1.6J new equipment to public networks;

• Existing 1.6J phase-out: Operators cease maintenance, functionality is restricted, and subsidy eligibility is revoked;

• PnC Plug-and-Charge: 2.0.1 exclusive, 1.6J cannot achieve, user experience gap.

2、 The cost of choosing the wrong version

At the hardware level

• 1.6J motherboard: Flash<1MB, no security chip TLS 1.2， Insufficient hardware resources;

• Upgrade 2.0.1: The main controller (Cortex-A7) needs to be replaced, Flash (2MB+) needs to be expanded, and a security chip (ATECC608) needs to be added, doubling the hardware cost;

• Certification restart: All CE, OCPP, and network security certifications of the entire machine are retested, doubling the certification cost.

Software level

• Protocol stack rewrite: 1.6J code cannot be smoothly migrated, Smart Charging, Device Management, Security extensions need to be redeveloped;

• Platform adaptation: Reconnect with the operator, with a cycle of 3-6 months, doubling the time cost;

• Firmware branch maintenance: 1.6J stock+2.0.1 incremental dual version parallel, doubling operation and maintenance costs.

market level

• Loss of admission qualification: 1.6J new machines after 2026 cannot access platforms such as EnBW and Ionity, and orders will be reset to zero;

• Subsidy exclusion: BAFA and SEDA only distribute to 2.0.1 equipment, resulting in loss of revenue;

• Brand devaluation: outdated technology label, high-end market exit.

3、 Decision tree for version selection

Procurement in 2024-2025

• Short term project (delivered within 1 year): 1.6J is acceptable, but hardware reserves of 2.0.1 capacity (Flash ≥ 2MB, secure chip pads) are required;

• Long term project (operating after 2026): Directly 2.0.1 to avoid upgrade pitfalls.

Procurement after 2026

• 1.6J is completely excluded, no matter how low the price is, buying it back will result in scrap metal;

• Verify 2.0.1 Full Profile (Core+Security+Smart Charging+Firmware Management), not just Core.

4、 Identify the "pseudo 2.0.1" trap

speech technique breakdown

• Support 2.0.1 ": Code exists, unauthenticated, functionality is castrated;

• 2.0.1 Ready ": Hardware reserved, software not burned, requires later payment for upgrade;

• Compatible with 2.0.1: 1.6J motherboard+external gateway, non-native, limited functionality.

Verify three moves

• Request OCA 2.0.1 certificate number for verification on the official website;

• Tested PnC plug and play charging, firmware update, and Security Event reporting;

• Disassemble and inspect the security chip, Flash capacity, and main control model.

5、 One sentence summary

Choosing the wrong OCPP version for the European standard home motherboard results in hardware replacement, certification reset, platform adjustment, and market elimination, with the overall cost doubling more than ever. Hardware reservation of 2.0.1 capability is required for procurement in 2024-2025, and 2.0.1 Full Profile certified models will be directly locked in after 2026. The saved price difference of 1.6J will be repaid tenfold in the future.
