CCS2 ↔ GBT Protocol Conversion

One vehicle.
Two standards.
One bridge.

Adaptx builds protocol-conversion adapters between CCS2 and GB/T, so any EV can plug into any DC fast charger. The hardware handles physical and protocol handshakes; the EVCC software connects every adapter to an OCPP charging platform — from plug-in to settlement, end to end.

01 / PRODUCTS

Two adapters. Full bidirectional coverage.

Whether your fleet is CCS2-native or GB/T-native, Adaptx lets it reach the other side’s charging network. Both products share one protocol-conversion core; only the physical interface and handshake timing differ by direction.

AX-C2G · Direction A

CCS2 to GBT Adapter

Connects a CCS2-standard vehicle to a GB/T DC fast charger. The on-board translation core converts ISO 15118 / DIN 70121 PLC communication into GB/T 27930 CAN frames in real time, while negotiating charging parameters and maintaining the safety interlock.

GBT to CCS2 Adapter

Connects a GB/T-standard vehicle to a CCS2 DC fast charger. Translates GB/T 27930 CAN charging messages back into ISO 15118 PLC frames, supporting both Plug & Charge (PnC) and external authorisation. Compatible with major operator networks across Europe, Southeast Asia and Australasia.

02 / TECHNOLOGY

Protocol conversion isn’t a dongle. It’s a translator.

CCS2 and GB/T don’t just differ in physical interface — their communication protocols, handshake sequences and safety models are entirely different. Adaptx performs real-time bidirectional translation in the middle, not simple pin remapping.

01

Physical-Layer Adaptation

CCS2 uses PLC (Power Line Communication); GB/T uses a CAN bus. Adaptx handles the physical mating of both buses and signal conditioning at the hardware level, ensuring handshake signals are correctly recognised on both sides.

02

Protocol-Layer Translation

ISO 15118 message structures and GB/T 27930 CAN frame formats are fundamentally different. The Adaptx core maintains a bidirectional mapping table and translates each frame in under 10 ms — covering authorisation, parameter negotiation, charging control and settlement.

03

Safety Interlock

The two standards use different safety models — CCS2 relies on PLC-layer digital signatures, GB/T on CAN-layer state-machine interlocks. Adaptx maintains independent safety state machines on both sides during translation; any anomaly on either side immediately cuts the charging circuit.

03 / EVCC PLATFORM

Beyond hardware, there’s a network.

The Adaptx EVCC (Electric Vehicle Communication Controller) connects every adapter to an OCPP charging operations platform. From remote authorisation and dynamic pricing to OTA updates, it turns protocol-conversion hardware into a manageable, billable asset.

Full OCPP 2.0.1 Support CORE

Complete implementation of the OCPP 2.0.1 specification, compatible with major CSMS platforms (Hubject, Has·to·be, Driivz, ChargePoint). Supports Plug & Charge (PnC), remote authorisation and local cached authorisation.

Remote Device Management OTA

Every adapter connects to the management console via EVCC, supporting firmware OTA updates, remote diagnostics and parameter push. Protocol mapping tables can be updated remotely — no factory return needed to support new vehicle or charger models.

Dynamic Billing & Settlement BILLING

Charging sessions are reported to the CSMS in real time, supporting time-of-use pricing, member discounts and roaming settlement. EVCC keeps local billing records and caches them offline during network outages, auto-syncing on recovery.

Telemetry & Alerts MONITOR

Real-time collection of voltage, current, temperature and handshake success rate. Anomaly events (over-temperature, handshake failure, communication loss) push to the operations platform within seconds, with webhook and email alerting.
