Which Public EV Charging Networks Do Drivers Trust the Most?

A 209-driver survey from research firm Escalent ranks Tesla's Supercharger network first on charging reliability, with owners rating both expected and real-world uptime ahead of every other major US public network, according to InsideEVs. The data shows public charging has improved faster than consumer sentiment, closing a perception gap that has shaped EV purchase decisions for years.

Survey methodology and top-line numbers

Escalent polled 209 EV owners and asked them to score each major network on a 1-to-5 reliability scale. Two separate scores: expected reliability, and the owner's actual experience over the previous six months. Tesla Superchargers topped both columns.

Sample composition matters here. 51% of respondents drove Teslas. That gives the plug-and-charge crowd an edge in user experience that other networks cannot replicate through hardware alone.

The aggregate satisfaction numbers still look strong. 45% of all respondents rated their overall public-charger reliability at 5 out of 5. 29% gave it a 4. Only 2% scored it a 1.

The expectation-experience gap

Every large network ranked higher on experienced reliability than on expected reliability. That's the central finding. Public perception lags the actual hardware improvements happening on the ground.

Stall uptime, payment authorization, and connector reliability have all moved forward across Electrify America, EVgo, and the Supercharger network over the past 18 months. The reported failure modes have shifted from chronic hardware downtime to occasional payment re-authorizations and rare regional outages.

One concrete data point: an Amazon Web Services outage took Superchargers offline for non-Tesla vehicles in some regions. That single event accounted for the bulk of reported charge failures across an 18-month window for at least one Ioniq 5 XRT owner. No thermal throttling at the stall. No connector handshake failures beyond that event. Two payment re-authorizations over the same period, no session terminations.

What the numbers mean for buyers

The reliability gap between Tesla and the CCS networks has narrowed in absolute terms. The convenience gap has not. Plug-and-charge remains a Tesla-native feature. CCS owners still authenticate through an app or card tap, and that is where most of the residual friction lives.

For buyers weighing network access before purchase: the reliability question is largely settled at this point. Multi-stall sites remain the practical hedge against single-stall failure. Single-stall risk is now the tail-end limitation, not the median experience.

The takeaway is straightforward. Network uptime has caught up to consumer expectations. The next metric worth tracking is session-to-session consistency on the CCS side, specifically how often a successful handshake turns into a completed charge without a second tap.
