The Rawsuns EVCC-A is an automotive-grade communication controller that enables seamless data exchange between electric vehicles and CCS (Combined Charging System) AC/DC charging stations compliant with European and North American standards. Mandated by EU regulations for all electric vehicles, the EVCC-A controls input/output channels, encrypts data transmission, and manages the entire charging session handshake between your vehicle and the Supply Equipment Communication Controller (SECC).
Core Functions
- CCS AC & DC Charging Support: Full compatibility with both AC and DC charging modes under the CCS standard.
- Secure Vehicle-to-Charger Communication: Encrypts and manages data transfer between EV and charging pile, ensuring safe authentication and parameter negotiation.
- ISO 15118 / DIN 70121 Compliance: Supports Plug & Charge (PnC), V2G (Vehicle-to-Grid), and international charging protocols for European and US markets.
- Electronic Lock Control & Monitoring: Integrated 3-wire/4-wire electronic lock driver with position feedback — supports both 12V forward/reverse control and status sensing.
- Dual CAN Architecture:
- CAN1: GB/T 27930 protocol interface with BMS
- CAN2: UDS diagnostics, OTA firmware upgrade, and customizable private protocols
- Smart Wake-up System: Multiple wake-up sources — CAN bus activity, IGN (key switch), and PP (Plug Present) detection — fully customizable.
- AUTOSAR Network Management: Industry-standard power management for seamless sleep/wake transitions and <100 µA standby current.
