Reliable EV fast charging: What to look for
EV fast charging that works the first time.
Driver experience is the #1 priority. Electric Era is the only EV fast-charging provider that financially guarantees both first plug-in success and per-port uptime.
What makes an EV fast charger reliable?
A reliable EV fast charger does two things: it’s working when a driver arrives, and it starts charging the first time the driver plugs in. For a retailer, each failed visit is a customer who drove to your store and left unhappy. Four questions decide reliability:
- 1Per-port uptimeHow often is each individual charger working?Jump to section
- 2First plug-in successHow many sessions start on the first try?Jump to section
- 3How problems get fixedWho gets asked when the charger isn’t working? Can a fix be made with software? Or does a truck need to go onsite?Jump to section
- 4Who is accountableWho gets blamed when a charger fails? Is reliability guaranteed with a dollar amount?Jump to section
What is per-port uptime, and how is it different from station uptime?
Per-port uptime measures how often each individual charger is working. Station uptime measures how often a site has at least some chargers working. Electric Era guarantees 98% per-port uptime, and our trailing 12-month average is 99.5%.

Charger 4Taped off
Many providers count a station as “up” when more than half its ports work. Under that rule, a site can report 100% uptime while half its chargers are broken.
98% uptime allows about 175 hours of downtime per port per year. 99.5% is about 44 hours.
Is your uptime per port or per station? Is it guaranteed, and what happens if you miss?
What is first plug-in success, and why does Electric Era guarantee it?
First plug-in success is the share of charging sessions that start the first time a driver plugs in, with no retries, no calls to support and no moving to another charger. It is the closest measure of what drivers actually experience, which is why it is Electric Era’s reliability north star.
Uptime tells you a charger was online. It doesn’t tell you whether a car actually started charging. A port can be “up” and still fail a handshake with a vehicle or reject a payment.
Electric Era guarantees a first plug-in success rate of 85% or better. If we miss, we refund O&M fees in proportion to the miss. We’re the only EV fast-charging provider that puts money behind first plug-in success, not just uptime.
Why we can offer it
We build the charger, the battery, the software and the firmware, and we see every session. When a vehicle model or software version starts causing issues, we spot the pattern and push a fix immediately.
Built to be easy to use
User error and confusion are among the biggest causes of failed sessions. Tap-to-pay and clear on-screen instructions help drivers start charging on the first try.
How does Electric Era fix charger problems so fast?
Electric Era treats charger reliability as a software problem. Most issues are fixed automatically by the charger itself in seconds. Our 24/7 operations center fixes nearly all remaining issues remotely. Together, that’s over 99% of issues resolved without a technician on site, and the rare truck roll arrives already knowing what’s wrong.
The charger heals itself.
Built-in recovery software detects, isolates and recovers from known faults, usually before a driver notices.
We fix it remotely.
Our 24/7 Network Operations Center pushes an over-the-air software fix.
A technician arrives ready.
The technician comes with a diagnosis, the right parts and tools, and fixes it on the first visit.
| Comparison | Typical network | Electric Era |
|---|---|---|
| First line of defense | Customer/driver complaint or support call | Automated alert and software that recovers automatically |
| Remote fixes | Limited, often a reboot | Over-the-air software updates, 24/7 |
| Truck rolls | Often to diagnose, then again to repair | <1% of issues, with diagnosis and parts |
| As the network grows | Support staff and OpEx grow linearly with station count | Gets more reliable with every site |
Why does owning the whole system make chargers more reliable?
Electric Era designs and builds the entire charging system: hardware, software, firmware and the power electronics inside. Because we own every layer, we see nearly everything between the grid and the car, and we can change any part of it with a software update.
We see everything.
Every component reports what it’s doing, live, on one shared system.
We control power on site, instantly.
A local controller at each site can adjust power in under 3 milliseconds.
We can update every layer remotely.
We wrote the code at every layer, so we can update any of it over the air.
One company is accountable.
No finger-pointing between hardware maker, software vendor and operator.
Frequently asked questions
What is the most reliable EV fast charger for retailers?
Look for a provider that guarantees first plug-in success and per-port uptime in the contract. Electric Era is the only one that financially guarantees first plug-in success (85% or better). We also guarantee 98% per-port uptime.
What is a good uptime for an EV charger?
The federal NEVI program requires at least 97% average annual uptime per port. A strong provider guarantees above that, measured per port. Electric Era guarantees 98%.
Why do public EV chargers fail so often?
There are two separate problems. Downtime: chargers go offline because of hardware faults in the power electronics or cooling, software and firmware bugs, lost network connections, problems with the site’s power supply, or physical damage like cut cables. Repairs are slow when problems are only found through driver complaints and every fix needs a technician visit. Failed sessions: even when a charger is up, a session can fail on the handshake with the vehicle, on payment, or because the driver isn’t sure what to do. Electric Era’s chargers recover from most faults automatically, and we fix session failures with software updates across the network.
Does EV charger reliability affect revenue?
Yes. Electric Era’s 2026 State of Retail-First EV Charging report found stations with reliability scores of 90 or higher averaged 17 sessions a day, versus 3 for stations below 90. Drivers stop returning to chargers that fail them.
What is first plug-in success rate?
The share of sessions that start charging the first time a driver plugs in, with no retries or calls for help. It measures what drivers actually experience, which uptime alone does not.
How does Electric Era fix chargers without sending a technician?
The charger’s software detects and recovers from known faults on its own. If that doesn’t work, our 24/7 operations center pushes a software fix over the air. Together that resolves over 99% of issues remotely.
Is Level 3 the same as DC fast charging?
Yes. “Level 3” is the common name for DC fast charging, typically 50 kW and up. Level 2 is slower AC charging.
Should a retailer install Level 2 or Level 3 chargers?
Match the charger to how long customers stay. For visits under an hour, like grocery, c-store or quick-service, Level 3 gives drivers a meaningful charge during the visit. Level 2 suits stays of several hours.
Does Electric Era make home or Level 2 chargers?
No. Electric Era builds and operates battery-backed DC fast-charging stations for retailers.
