FAQ
1How many charging connectors does one ChargeBridge module support?
One ChargeBridge module supports up to 2 charging connectors.
2What is the technical architecture of ChargeBridge?
ChargeBridge consists of two components. The first runs on a Linux System on Module (SoM) handling all "high-level" communication. The second handles core charging logic, or "low-level" communication. Since all safety-relevant code must execute quickly without latency and independently of Linux code, this is handled by ChargeBridge firmware embedded in a microcontroller. It can even charge cars (using PWM), though it lacks the complexity for smart charging apps. Only the perfect combination of these two ensures a safe, reliable charger while maintaining full functionality.
3Which charging standards does the ChargeBridge module support?
Designed for European and American markets, ChargeBridge covers protocols like CCS1/CCS2/NACS/MCS. Thanks to its standardized pin-compatible design, it offers great flexibility—you can swap hardware if the controller design permits. This means seamless switching between US and EU standards by simply replacing the ChargeBridge module (and cable), significantly reducing hardware costs for different markets.
4Which vehicle models has ChargeBridge been tested with?
