EV Charging Network Reliability Report
Charging reliability is a top concern for EV drivers. This report summarizes published uptime ranges and common issues across major US charging networks. For ChargingNear.me's own measured scores, see the EV Charging Reliability Index.
Overall Reliability
Average uptime across all monitored networks is approximately 80-85%. Tesla Superchargers lead with 95%+ uptime, while some smaller networks report 70-75% availability. Station age, weather, and utilization rates all affect reliability.
Network Comparison
Tesla Supercharger: 95%+ uptime. Electrify America: 85-90%. ChargePoint: varies by host (80-95%). EVgo: 85-90%. Blink: 75-85%. These are industry-reported ranges, not ChargingNear.me measurements; our own 30-day scores (published only for stations with at least 10 reports) are on the EV Charging Reliability Index at /ev-charging-reliability.
Common Issues
The most common reliability issues include: payment system errors (32%), connector/cable damage (24%), communication failures (18%), screen/display issues (14%), and power delivery problems (12%).
Improving Reliability
The federal minimum uptime standard of 97% for NEVI-funded stations is driving network-wide improvements. Remote diagnostics, predictive maintenance, and faster repair response times are becoming industry standard.
