On 7 September, the Association has released the Design Guideline for External Charging ver.1.0 to its Regular Members.
The document describes the key technical requirements for safely integrating or retrofitting the so-called ‘external charging systems’ such as WPT, pantograph and long-plug* systems to CHAdeMO EVs and PHEVs with little or no modifications to the on-board interface and components that already exist in the vehicles. The versatile CAN-based communication and interface circuit with multiple control pilot signals adopted in CHAdeMO protocol also help to simplify the process of implementation.
Examples of vehicles integrating the external charging system based on the Design Guideline for External Charging ver.1.0 are listed below.
- INTIS’s WPT charging systems retrofitted to Nissan LEAF and Citroën Berlingo EV
- TALAKO project with INTIS’s WPT charging systems retrofitted to LEVC TX
- Electric buses with pantograph charging system operating in Malaysia, as part of NEDO project
The Guideline is adapted to pantograph and long-plug charging up to the max current of 1,000A and is fully compliant with the upcoming IEC 61851-23-1 ED1.
The CHAdeMO External Charging WG has been working on the development of the Guideline for more than 5 years and is continuing to explore further opportunities to cover a wider range of external charging systems including automatic connection device (ACD) and dynamic-WPT to be integrated to the existing and future CHAdeMO EVs and PHEVs.
