ChargeBridge: Decoupling What Should Never Have Been Coupled

ChargeBridge is a plug-and-play charging control module built to simplify system integration and drastically reduce development complexity.

The architectural principle is simple, but powerful:

• High-level communication and system integration run on a Linux-based CPU board powered by EVerest
• All low-level communication and safety-critical charging logic are handled by the microcontroller inside ChargeBridge
  

This separation creates flexibility where innovation is needed — and stability where safety is critical.

At the heart of the module is Lumissil Microsystems’ IS32CG5317 Green PHY, enabling robust and reliable AC and DC communication

For manufacturers, this means:

• Reduced integration risk
• Faster certification cycles
• A significantly shorter path from development to mass production

Why Lumissil?

Hardware partnerships in the EV industry are not just about silicon performance - they’re about engineering collaboration.

Lumissil was selected as a strategic hardware partner not only for its high-performance GreenPHY solution but also for its hands-on integration support during development.

For embedded teams working against aggressive timelines, responsive technical support can be the difference between months of delay and a clean ramp to market.

Powered by EVerest: Open, Scalable, Future-Proof

Pionix ChargeBridge modules are powered by the EVerest open-source charge controller software running on a local Linux system

EVerest supports:

• ISO 15118-2 and ISO 15118-20
• MCS
• OCPP 1.6, 2.0.1 and 2.1
• Plug & Charge
• Energy Management
• Eichrecht
• Payment use cases
  

In 2025 alone, EVerest-powered systems expanded from 10,000 to over 400,000 charging stations in the field

Backed by more than 80 companies and a community of 600+ contributors, EVerest has become one of the most dynamic ecosystems in EV charging software

For manufacturers, this eliminates the “compatibility lottery” and replaces it with a standardized, globally validated software foundation.

From CCS to MCS — Without Redesigning the Entire Charger

One of the biggest advantages of a software-defined, modular architecture is adaptability.

By combining Pionix ChargeBridge with EVerest, manufacturers can decouple hardware and software — and even switch charging standards simply by exchanging the Pionix ChargeBridge module and charging cable!

That means the same base platform can support:

• CCS1 / CCS2 / NACS
• MCS
• CHAdeMO
• ChaoJi
• GB/T

In a market where standards evolve and regional requirements differ, this flexibility becomes a much needed strategic advantage.

A Shift Toward Software Defined Charging

The EV charging industry is moving from hardware-centric design toward software-defined systems.

This shift enables:

• Faster innovation cycles
• Lower total cost of ownership
• Continuous feature deployment
• Better interoperability

Pionix ChargeBridge represents a concrete step in this direction: a modular, pre-certified hardware foundation powered by a globally adopted open-source software stack.

Or, as Marco Möller, CEO of Pionix, puts it:

"Time-to-market and interoperability are the two biggest hurdles in the EV industry today. With Pionix ChargeBridge, we provide a turnkey solution that solves both. Lumissil has been a fantastic partner, providing the reliable chip technology and the agile support we need to help our customers scale faster than ever before."

Building the Infrastructure for Mass EV Adoption

The transformation of mobility depends on scalable, reliable charging infrastructure.

By combining Lumissil’s semiconductor expertise with Pionix’s open-source software leadership, we are enabling manufacturers to innovate faster — and deploy interoperable charging systems at scale.

Software-defined charging is no longer a vision.
It is becoming the new industry standard.

And Pionix ChargeBridge is built to power it.
