Fire compartment design

　　In terms of solutions, Kehua, based on the design concept of "fire compartment", completes designs in strict accordance with professional fire protection standards, to achieve scientific planning and ensure safety. Kehua is capable of providing comprehensive solutions for safety problems related to charging, ensuring that preventive measures are sufficient to prevent fire.

Intelligent analysis on fire alarm

　　In terms of asset management software, real-time data can be scheduled and monitored to ensure the safety of transformers. The charging safety information can be detected in real time, and any abnormality timely reported and stored according to the abnormal level.

Relay-free switching technology

　　Kehua has independent patent LLC (resonant soft switching) technology. The LLC uses relay-free switching technology. This ensures that the output power is free of interruption, eliminating the arcing risk when the relay is shut off.

Nuclear-grade full dip-coating process, providing nuclear island-level protection

　　By virtue of its unique technical advantage (i.e., nuclear-grade full dip-coating process), Kehua can provide nuclear island-level protection for equipment, ensuring that the equipment can operate stably under conditions of high-level salt spray, high humidity and high temperature.

Intelligent O&M

　　With an automatic address recognition function, Kehua charging module realizes plug and play, which makes O&M easier.

　　The use of innovative pull-out dustproof and maintenance design makes sure that the maintenance of charging pile can be completed in 5 min, which not only improves the charging experience of car owners, but also minimizes the O&M costs and increases the benefits of merchants.

The life prediction mechanism for key devices is also provided to predict service life and realize intelligent early warning.
