7. Low Satisfaction with Highway Charging
Highway charging satisfaction is the lowest, with 85.4% of users complaining about long queue times. The shortage of charging facilities on highways severely impacts the charging experience for long-distance travel, requiring an increase in the number and power of charging stations.
III. Analysis of User Charging Behavior Characteristics
1. Charging Time Characteristics
Compared to 2022, the electricity price during 14:00-18:00 has increased by approximately 0.07 yuan per kWh. Regardless of holidays, the trend in charging times remains the same, highlighting the influence of pricing on charging behavior.
2. Characteristics of Single Charging Sessions
The average single charging session involves 25.2 kWh, lasts 47.1 minutes, and costs 24.7 yuan. The average single session charging volume for fast chargers is 2.72 kWh higher than for slow chargers, indicating increased demand for fast charging.
3. Usage Characteristics of Fast and Slow Charging
Most users, including private, taxi, commercial, and operational vehicles, are sensitive to charging time. Different types of vehicles use fast and slow charging at different times, with operational vehicles primarily using fast chargers.
4. Characteristics of Charging Facility Power Usage
Users predominantly choose high-power chargers above 120kW, with 74.7% opting for such facilities, a 2.7 percentage point increase from 2022. The proportion of chargers above 270kW is also increasing.
5. Choice of Charging Locations
Users prefer stations with free or limited-time parking fee exemptions. The construction proportion of stations with 11-30 chargers has decreased, showing users' preference for dispersed, smaller stations with supporting facilities to meet charging needs and alleviate "long wait" anxiety.
6. Cross-Operator Charging Characteristics
More than 90% of users engage in cross-operator charging, with an average of 7 operators and a maximum of 71. This reflects that a single operator's service range cannot meet users' needs, and there is a large demand for composite charging operation platforms.
7. Cross-City Charging Characteristics
38.5% of users engage in cross-city charging, a 15 percentage point increase from 2022's 23%. The proportion of users charging across 4-5 cities has also risen, indicating an expanded travel radius.
8. SOC Characteristics Before and After Charging
37.1% of users start charging when the battery SOC is below 30%, a significant decrease from last year's 62%, indicating an improved charging network and reduced "range anxiety." 75.2% of users stop charging when SOC is above 80%, showing users' awareness of charging efficiency.
IV. Analysis of User Charging Satisfaction
1. Clear and Accurate Charging App Information
77.4% of users are primarily concerned with the low coverage of charging stations. Over half of the users find that apps with few cooperating operators or inaccurate charger locations hinder their daily charging.
2. Charging Safety and Stability
71.2% of users are concerned about unstable voltage and current in charging equipment. Additionally, issues like leakage hazards and unexpected power cuts during charging also worry over half of the users.
3. Completeness of the Charging Network
70.6% of users highlight the issue of low network coverage, with over half noting inadequate fast-charging coverage. There is a need to further improve the charging network.
