This technology implements ISO 15118-20 AC-BPT protocol via WiFi TCP connection, with EVCC as the client and SECC as the server, using three-way handshake. It covers session setup, authorization, service scheduling, and power transfer, ensuring secure, efficient charging with multi-certificate and scheduling algorithm support.

This technology advances ISO 15118-20 with multi-certificate authentication, boosts security and compatibility. Battery wear-based scheduling algorithms address monitoring gaps, improving charging efficiency.

This technology applies to EV charging and Vehicle-to-Grid systems, using battery wear-based scheduling to cut costs by 30% and CO₂ by 1.8%. Without hardware upgrades, it suits public chargers and smart homes, driving green transport and energy management upgrades.
