Get In Touch | EcoG Charging Reliability Index 2025

Executive Summary

Combatting issues with reliability and building trust

Concerns about EV charging reliability are replacing range anxiety as one of the biggest hurdles for the adoption of electric mobility. Studies show that still 1 in 10 charging attempts fail. The implementation of the interface between the charging station and the electric vehicle (EV) is one of the crucial elements in the charging reliability as errors most likely cannot be resolved remotely when they occur.

EcoG published the second edition of the EcoG Charging Reliability Index (CRI), a benchmark study that evaluates how reliable electric vehicles (EV) charging interfaces are implemented and interact with CCS fast-charging infrastructure globally.

Following the success of the first CRI report in 2023, the 2025 edition expands the scope by testing the 10 global EV platforms, focusing on 4 categories: Reliable Charging Initialization, Robust Charging Process, Error Recovery and User Information.

76%

The Highest EcoG CRI Value

Overall, no platform scored more than 76/100 in all 4 test categories. This shows that fundamental flaws still remain, which can cause substantial frustration among EV drivers and even breakdowns of EVs on the road.

39%

The Lowest EcoG CRI Value

One platform scored only 39/100 in all 4 test categories, calling for substantial need for improvement to enable an acceptable user experience and mass adoption of electric vehicles.

30%

Potential Risk of Car Breakdowns Due to Depleted 12V Batteries

3 out of 10 vehicle platforms repeated the charging starting process infinitely if a charging attempt fails, placing a heavy drain on the 12V battery.
