Robust quality management system and AAA credit rating, ensuring reliability in every module.
The Open Charge Point Protocol (OCPP) has emerged as the global "universal language" for the EV infrastructure. As of 2024, the transition from OCPP 1.6J (JSON over WebSockets) to OCPP 2.0.1 is accelerating. This shift is driven by the need for enhanced security, ISO 15118 integration (Plug & Charge), and complex smart charging capabilities.
From European municipal projects to North American commercial fleets, the demand for "interoperability" is paramount. Global buyers are no longer just looking for hardware; they are seeking future-proof systems that can integrate with various Central Management Systems (CMS). Our OCPP 2.0.1 compliant chargers ensure that operators can switch software providers without replacing hardware, significantly reducing the Total Cost of Ownership (TCO).
From PCB design to plastic injection and final assembly, we control the entire lifecycle, ensuring competitive pricing and rapid lead times.
Our R&D team in Dongguan can iterate firmware updates for new EV models within weeks, keeping your infrastructure current with the latest Tesla, BYD, or VW protocols.
