EVCI - The Diamond Standard for EV Charger Accuracy
Strengthen customer trust, protect revenue integrity, and earn the badge that brings drivers in – and brings them back again.
The Hidden Problem in Electric Vehicle Charging.
We all expect to get what we pay for when we plug in. But our testing shows that’s not always the case – some chargers give more, some less. Here’s what the real-world data shows:
0
%
of UK chargers tested fall outside ±2% accuracy.
+
0
%
of chargers we've tested exceed ±5% error margin.
-
0
%
The biggest errors so far? -37% too little and +30% too much energy delivered.
This creates serious risks:
1. Drivers may not be receiving the energy they’re paying for.
2. Charge Point Operators risk silent revenue erosion and reputational damage as small metering inaccuracies compound across their network.
3. Public confidence in EV charging depends on transparent, independently verified accuracy at every charge point.
Our Solution
- Independent testing using ±0.1% reference meters.
- Verification against MID Class A (±2%).
- Diamond Standard certification for each passing charger and site.
- Annual re-testing for drift detection.
