Wilko Behrend developed two core features for the evcc-io/evcc repository over a two-month period, focusing on Tesla BLE integration. He designed and implemented a Tesla BLE HTTP Proxy Integration Template, enabling configurable VIN, URL, and port parameters, and exposing HTTP endpoints for vehicle command and data retrieval. Using YAML for configuration and leveraging API integration skills, Wilko also delivered a getmaxcurrent endpoint to dynamically fetch a vehicle’s maximum charging current via the charge state API. His work established a scalable, template-based pathway for future Tesla BLE integrations, emphasizing maintainability and automation without addressing bug fixes during this timeframe.
October 2025 contribution for evcc-io/evcc: Delivered a Tesla BLE feature to retrieve the vehicle's maximum charging current with a new getmaxcurrent endpoint. Implemented in tesla-ble.yaml to fetch charge_amps via the charge state API, enabling dynamic charging configurations. No major bugs fixed in this period (per provided data). Impact: improved charging configurability, safer and more efficient charging, with traceable delivery through commit-level records. Technologies demonstrated: YAML-based configuration, API integration, and commit-based change tracking.

December 2024 (evcc-io/evcc): Delivered a new Tesla BLE HTTP Proxy Integration Template enabling VIN/URL/port configuration and HTTP endpoints for vehicle commands and data retrieval. The feature supports charging control, current limit setting, wake-up, and state monitoring, establishing a scalable integration path for Tesla BLE via HTTP. This work lays the foundation for automation, improved interoperability, and faster integration of Tesla vehicles into the EVCC platform.
