Why the industry’s favorite metric is failing drivers — and what real reliability should mean.
The EV Charging Uptime 'Lie'
When EV service providers claim “95–98% uptime,” it sounds reassuring. But what if that number doesn’t actually reflect what drivers experience?
A recent study of public DC fast chargers in California found that only 72.5% were truly functional, even as networks boasted near-perfect uptime. That gap isn’t a rounding error — it’s a trust deficit. And it’s holding back EV adoption.
The Problem: What “Uptime” Really Measures
In today’s EV infrastructure world, “uptime” is often defined by network connectivity — whether a charger can “talk” to the central system.
But connectivity alone doesn’t mean a charger works. Drivers face countless issues that never show up in uptime dashboards:
- Frozen or unresponsive touchscreens
- Failed payment terminals or app authorizations
- Incomplete handshake between EV and charger
- Broken connectors or cables too short to reach the inlet
From a driver’s perspective, a charger that’s “online” but unusable is still down. Yet by current standards, it often counts as operational.
Why It Matters for Businesses
This “uptime lie” isn’t just an inconvenience — it’s an operational risk.'
- For fleets, failed charging sessions translate directly into missed routes, idle vehicles, and lost revenue.
- For retailers, unreliable chargers turn a high-cost investment into a customer frustration point.
- For utilities and municipalities, unreliable public infrastructure undermines the EV transition itself.
The stakes are too high for metrics that don’t reflect reality.
Redefining Reliability: From Connectivity to Experience
True reliability should measure what actually matters — a successful, end-to-end charging experience. That means tracking:
- Successful session initiation
- Energy delivered vs. promised power
- Completion without dropouts
- Verified payment success
It’s time for the industry to move beyond uptime as a checkbox metric and toward trust-based performance metrics grounded in driver experience.
How Energos is Addressing the Uptime Gap
At Energos.ai, we believe reliability starts with visibility. Our platform unifies data from chargers, networks, and maintenance systems to measure what matters:
- Real-time fault detection across firmware, power modules, and payment layers
- Automated diagnostics that convert error codes into actionable insights
- Predictive alerts that flag issues before they impact a session
- Work order automation to reduce downtime and improve mean time to repair (MTTR)
By redefining reliability around outcomes, not connectivity, we’re helping Charge Point Operators (CPOs) and site hosts deliver what drivers expect: chargers that simply work.
The Road Ahead
We can’t solve EV reliability until we measure it honestly. The industry’s next evolution depends on transparency, collaboration, and technology platforms that connect the dots across the charging ecosystem. Because the future of EV charging doesn’t run on uptime — it runs on trust.
