Health categories describe the evidence in recorded data. They are prompts to inspect, not safety certifications.
Station performance
How each station performed in the stored charging sessions, with sample sizes and uncertainty, so a difference is only called a difference when the data supports it.
What the data shows
Historical data · 01 Jan 2024 – 11 Jan 2024 · 1,000 sessions
Station high-loss shares range from 16% to 35% (fleet 26%). None is clearly above the fleet once sample size and the number of stations compared are taken into account.
The high-loss share ranges from 25% (Rural) to 27% (Urban), but the 95 % intervals overlap — the 2%-point gap is within what chance alone could produce.
The high-loss share ranges from 25% (V2G) to 27% (Fast), but the 95 % intervals overlap — the 2%-point gap is within what chance alone could produce.
The daily high-loss share moved between 20% and 28% with no consistent upward or downward trend (robust slope 0 points per day).
High-loss share by station
Share of each station's labelled sessions marked “High” loss, with its 95 % interval. Stations whose interval sits wholly to the right of the fleet line are clearly above it.
High-loss share by station
Station 835% (24%–48%) n=60
Station 234% (22%–48%) n=50
Station 1033% (20%–47%) n=43
Station 1331% (20%–45%) n=51
Station table
Select a column heading to sort. Energy is derived from charging power × time; time is assumed to be minutes.
Not calculated: utilisation, downtime, availability and failed-session rate — the data has no per-charger availability, downtime or session outcome, and the number of chargers per station changes between rows. Inconsistent records = sessions that lose more power than they consume plus sessions that deliver more energy than the battery holds.
