The global electric vehicle infrastructure is transitioning from simple analog signaling to the sophisticated ISO 15118 standard. Known as the "Road Vehicles — Communication Interface" standard, it defines a digital network-based communication between the EV and the Charging Station (EVSE). As a leading China ISO 15118 communication module factory, we recognize that this protocol is the backbone of the "Plug & Charge" ecosystem, eliminating the need for RFID cards or mobile apps.
In Europe and North America, the adoption of ISO 15118 is no longer optional but a strategic requirement for commercial charging networks. It enables Vehicle-to-Grid (V2G) and Vehicle-to-Home (V2H) bidirectional energy transfer, turning EVs into mobile energy storage units. Our modules are designed to meet these rigorous global demands, ensuring seamless interoperability across different vehicle brands and grid systems.
Providing ONE-STOP System Energy ODM Solutions
Dongguan Rama Charger Technology Co., Ltd. is a technology-driven enterprise integrating R&D, design, manufacturing, sales, and service into a seamless operation. We specialize in providing comprehensive system energy solutions for electric vehicle charging and related applications.
With strong independent R&D capabilities in charging controllers, Rama Charger can provide customized core master control boards for charging pile manufacturers. Over the years, we have established collaborations with numerous leading charging pile enterprises domestically and internationally, delivering outstanding ODM results and tailored solutions.
Our headquarters has obtained multiple authoritative certifications, including DEKRA CB, CE, ISO9001, as well as recognition as a high-tech enterprise and technology SME. We maintain a robust quality management system and AAA credit rating, and have secured 15 software copyrights, multiple invention patents, utility model patents, and design patents, reflecting our commitment to innovation and excellence.
Modern ISO 15118-2 and ISO 15118-20 standards require robust Transport Layer Security (TLS). Our communication modules integrate hardware-based secure elements to manage digital certificates, ensuring that payment and vehicle data remain uncompromised during the charging session.
The industry is moving beyond one-way charging. ISO 15118-20 introduced support for bidirectional DC and AC charging. This allows fleet operators and homeowners to sell energy back to the grid during peak hours, creating new revenue streams and balancing the load.
Convenience is the ultimate driver for consumer adoption. Our SECC (Supply Equipment Communication Controller) modules allow chargers to identify vehicles automatically. No more apps, no more cards—just plug in and the module handles authorization and billing securely.
Integrating ISO 15118 modules into office building chargers allows for smart load balancing, ensuring the building's peak demand isn't exceeded while providing fast charging for employees.
For logistics fleets, our modules enable automated scheduling. Vehicles are identified instantly, and charging is prioritized based on departure times and battery levels.
Homeowners can use our bidirectional modules to power their homes from their EVs during grid outages, creating a truly resilient smart home energy ecosystem.
As a leading China ISO 15118 communication module factory, Dongguan Rama Charger Technology Co., Ltd. continues to bridge the gap between vehicles and the grid. Our DEKRA certified solutions are at the forefront of the electric mobility revolution, ensuring that every charge is smart, secure, and sustainable.
