Description

[0002] Currently, fuel cell engines in the new energy industry are being widely promoted and applied in the automotive sector due to their water-only emissions, zero pollution, increased driving range, and rapid hydrogen refueling, which shortens charging time. OTA (Over-The-Air) technology has been used in computers and mobile phones for many years and is relatively mature. In recent years, with the increasing popularity of the concept of the Internet of Things, the advantages and roles of OTA technology have become increasingly prominent in industries such as smart home appliances and intelligent connected vehicles. Wireless download technology can safely and conveniently upgrade device firmware or software. At the same time, remote upgrades can significantly reduce costs and save resources, making it one of the key technologies for IoT device and product manufacturers. Existing vehicle data acquisition devices only have the function of remotely acquiring and monitoring data, and do not have the function of OTA remote download updates. Currently, fuel cell system data or programs do not support remote updates, making it impossible to promptly correct and avoid predicted faults, causing problems or faults to recur. Furthermore, faults must be repaired on-site, requiring replacement or disassembly, wasting time and effort, increasing maintenance costs, and negatively impacting customers.
