Highway EV Charging Hits Record High on May Day, Up 55.6% Year-on-Year

May Day Travel Rush: Highway EV Charging Sets New Record

On the first day of the 2025 May Day holiday, highways across China experienced a massive travel surge, accompanied by a sharp spike in charging demand for new energy vehicles (NEVs). According to the latest data released by the National Energy Administration, highway NEV charging volume reached 23.0339 million kWh on May 1, a 55.6% year-on-year increase. The number of charging sessions exceeded 946,300, smashing the previous record for the first day of a May Day holiday.

Smart Monitoring Platform Serves as Core Safeguard

The data was sourced from the National Charging Infrastructure Monitoring and Service Platform, which conducted comprehensive statistical analysis of 57,600 highway charging units (guns) included in its nationwide tracking system. The operation of this intelligent monitoring framework marks a significant milestone in China's digital management capabilities for charging infrastructure.

Leveraging big data analytics and intelligent dispatching technologies, the platform can monitor the operational status, queuing conditions, and power loads of charging stations at service areas in real time. It provides drivers with precise charging guidance services, effectively alleviating the challenge of long queues at popular highway segments.

Proactive Planning and Targeted Measures Ensure Smooth Travel

The National Energy Administration deployed proactive and targeted measures ahead of the holiday, guiding local authorities to carry out multiple safeguard initiatives:

• Facility Inspection and Maintenance: Local authorities were required to conduct comprehensive inspections of charging facilities at service areas in advance, ensuring equipment availability met required standards.
• Intelligent Vehicle Dispatching: Enhanced smart dispatching of charging vehicles to guide drivers toward optimal charging stations and avoid overcrowding.
• Green Travel Assurance: Full commitment to meeting public demand for green, worry-free holiday travel.

These measures provided a solid infrastructure foundation for the significant surge in charging volume on the first day of the holiday.

Behind the Numbers: Accelerating NEV Penetration

The 55.6% year-on-year increase is more than just a number — it reflects the robust growth momentum of China's NEV market. On the demand side, an increasing number of consumers are choosing NEVs for long-distance travel, indicating that "range anxiety" is being progressively overcome. On the supply side, the coverage density and service capacity of highway charging infrastructure continue to improve.

Notably, the deep integration of artificial intelligence and IoT technologies into charging networks in recent years has significantly enhanced operational efficiency and user experience. AI-driven features such as smart station recommendations, reservation-based charging, and dynamic power allocation are becoming standard offerings in charging services.

Outlook: Intelligent Charging Networks Poised for Greater Growth

As the NEV fleet continues to expand, highway charging infrastructure development will remain a key investment priority for years to come. Industry experts predict that by combining AI-powered intelligent dispatching, V2G (Vehicle-to-Grid) technology, and integrated solar-storage-charging solutions, China's highway charging network will accelerate toward a smarter, more efficient, and greener future — paving the way for the widespread adoption of new energy vehicles.
