December 2025 monthly summary for evcc-io/evcc. Focused on delivering a Renault SoC limiter feature to cap charging state of charge, enhancing battery management, safety, and charging predictability. Implemented as commit 709fc827e21940b25e63005415dd416c810d8b47 (Renault: add SocLimiter, #25757), co-authored by andi. This work improves user control over charging behavior, supports smarter energy usage, and reduces variability in charging outcomes.

November 2025: Delivered a robust charger connection state enhancement for evcc, improving reliability of connection monitoring and welcome charge handling. The change detects connection changes by monitoring the connected duration, refactors the charger status update logic to better handle intermediate disconnects, and ensures welcome charges are applied only once. This reduces edge-case failures and strengthens session stability.

Month: 2025-10 — Focused on strengthening connection reliability for EV charging workflows by introducing timer-based connection change detection. Delivered a new ConnectionTimer interface and PhoenixCharx implementation to monitor the connected duration and detect connection changes, with integration into loadpoint logic to surface intermediate disconnects and stabilize session state. Commit reference: c023b080d6fcf98fe5b8c4e187cff54b33eaf644 (Loadpoint: detect connection changes using connected duration (#24730)). Impact: reduced false disconnects, improved session continuity, and more accurate energy management decisions. Technologies/skills demonstrated: Go interface design, timer-based state detection, loadpoint integration, testing readiness. Business value: higher reliability, improved user experience, and smoother automation workflows across charging sessions.
