A We have built a dual service system of "digitalization+localization". Through the built-in intelligent gateway, our engineers can achieve remote online diagnosis of over 90% of faults. For hardware replacement, as we use standardized module design, non-technical personnel can also complete module hot plug replacement under guidance. We will establish spare parts centers in major market regions or allocate a certain proportion of "emergency spare parts packages" to customers based on order size. In addition, we provide detailed video tutorials and multilingual technical manuals to ensure that customers worldwide can enjoy a worry free after-sales experience.

A Jiuroad's DC fast charging system adopts a highly integrated modular architecture. This means that if a power module fails, the system will automatically isolate that module and keep other modules working, achieving * * "non-stop maintenance" * *. For operators, this means zero downtime risk. At the same time, this design has strong scalability: if you invest 480kW initially, as the traffic volume increases later, you can upgrade to 960kW or higher by simply adding module slots, without the need to replace the entire machine foundation and main cables, greatly protecting your asset value.

A Traditional fixed power allocation can lead to serious energy waste. Jiuroad's fully flexible power stack adopts dynamic matrix switching technology. When multiple vehicles are charging simultaneously, the system does not simply distribute the current evenly, but schedules it in milliseconds based on the real-time BMS requirements of each vehicle. For example, when a car is about to be fully charged (entering trickle charging), the system will automatically transfer the released module power to another vehicle that is in a low battery state and requires high current fast charging. This "on-demand allocation" logic can increase the daily average charging capacity of a single station by about 15% -20%, significantly shortening the customer's return on investment (ROI).

A Interconnection is the core of Jiuroad products. Our entire line of DC and AC products natively support the OCPP 1.6J protocol and have completed the technical iteration towards OCPP 2.0.1. To ensure seamless integration, our software team provides standard API interfaces and whitelist configuration services. Before official deployment, we can conduct interoperability testing by accessing the customer's backend system through remote VPN to ensure that core functions such as charging startup, real-time billing, remote diagnosis, and firmware upgrade (OTA) run stably on your private cloud or third-party platform.
