Pionix GmbH, a pioneer in open-source EV charging software, and Lumissil, a semiconductor company specializing in analog and mixed signals, have deepened their collaboration to develop ChargeBridge - a pre-certified, plug-and-play System-on-Module (SoM) that simplifies the integration of charging systems. By combining Pionix's software expertise with Lumissil's reliable silicon, the partnership enables EV charger manufacturers to significantly accelerate development cycles and ensure seamless interoperability across the global charging ecosystem.

Why it matters

The EV charging industry has faced challenges around time-to-market and interoperability, which have hindered widespread EV adoption. Solutions like ChargeBridge, powered by Pionix's EVerest open-source software, aim to transform the industry by empowering manufacturers to innovate faster, reduce costs, and enhance user experiences - ultimately building the infrastructure needed for widespread EV adoption.

The details

ChargeBridge utilizes Lumissil Microsystems' IS32CG5317 Green PHY chip for robust EV-Charging (AC and DC) communication. Pionix selected Lumissil as its strategic hardware partner not only for their high-performance silicon but for their exceptional technical support during the integration phase. ChargeBridge is powered by the EVerest Open Source Charge controller Software, which supports all major protocols and provides the business logic needed to build reliable and future-proof chargers. EVerest has seen explosive growth, expanding from 10,000 to over 400,000 charging stations in the field within 2025 alone, backed by over 80 companies and a community of 600+ contributors.

  • ChargeBridge was developed and launched in 2026.
