In March 2025, Mats developed dynamic EV charging control for Tessie vehicles in the evcc-io/evcc repository, enabling start and stop actions based on a charge enable flag. This feature was implemented through a traceable commit tied to a specific issue, focusing on configuration and integration with Tessie systems. Mats used Go and yaml to deliver this targeted functionality, which improved session control and reduced unnecessary energy consumption. The work addressed demand-response requirements by allowing more granular management of charging sessions. Over the month, Mats concentrated on feature development rather than bug fixes, demonstrating depth in configuration-driven, feature-focused engineering within the project.
