Gradual Improvement of the DC Charger Industry Standard System Promotes Standardized Product Development
May 09,2026
With the continuous growth of new energy vehicle ownership, the standard system of the DC charger industry is also constantly improving, forming full-process technical requirements covering interface specifications, communication protocols, safety protection and operation management. At present, mainstream domestic DC chargers comply with national standards such as GB/T 20234 and GB/T 27930, clarifying key indicators such as charging interface dimensions, communication protocols, insulation performance and electromagnetic compatibility to ensure compatibility between different brands of vehicles and chargers.
In terms of safety standards, mandatory requirements are set for functions such as overcurrent protection, leakage protection, insulation monitoring and emergency shutdown. Some scenarios also need to meet special specifications such as fire protection, lightning protection and corrosion resistance. Operation management standards put forward unified requirements for billing settlement, data transmission and user information protection to promote standardized station operation. The improvement of the standard system guides enterprises to optimize product design and production processes, reduces compatibility issues and potential safety hazards, and provides a basis for industry supervision and quality inspection, helping the DC charger industry develop steadily in a compliant and standardized direction.
