Public EV Charger Not Working? 8 Checks to Make Before You Switch Stations

Public EV Charger Not Working? 8 Checks to Make Before You Switch Stations

Nothing is more frustrating than arriving at a public EV charging station with a low battery, plugging in, and finding that charging never starts. Before you drive to another location, it is worth knowing that many charging failures are temporary or caused by simple issues that can be resolved in minutes. 

If you are wondering about the best way to charge an electric car when a public charger is not working, this guide explains the most common causes, the technical checks you should perform, and when it is actually time to switch stations. 

Whether you are charging a Tesla, Rivian, Ford F-150 Lightning, Hyundai Ioniq 5, Kia EV6, Lucid Air, Porsche Taycan, BMW i4, or another EV, these troubleshooting steps can save valuable time and reduce range anxiety. 

Why Public EV Chargers Sometimes Fail

Modern EV charging stations are far more complex than traditional fuel pumps. A successful charging session needs multiple systems to communicate simultaneously:

  • Vehicle Battery Management System (BMS)
  • Charger controller
  • Payment network
  • Authentication server
  • Charging protocol (CCS, NACS, J1772)
  • Internet connectivity
  • Electrical safety monitoring 
  • Thermal management 

If any of these systems fails, charging may not start. Studies evaluating public DC fast chargers have found that real-world functionality can be significantly lower than advertised uptime because of payment failures, connector problems, communication errors, and unavailable equipment. 

  1. Check Whether the Charger is Actually Available 

Many drivers immediately assume that the charger is broken. Instead, verify: 

  • Is someone already using it? 
  • Does the app show ‘Reserved’?
  • Is maintenance underway
  • Does the screen display ‘Offline’?
  • Is the station rebooting? 

Apps like Tesla, PlugShare, ChargePoint, Electrify America, and EVgo often display real-time charger status before you plug in. 

Tip: If multiple stalls are available, choose one that recently completed a charging session. 

  1. Confirm You Are Using the Right Connector

Connector compatibility remains one of the most common causes of failed charging. 

Vehicle 

Common Connector

Tesla (NACS)

NACS

Ford (new models)

NACS or CCS with adapter

Hyundai 

CCS

Kia

CCS

BMW

CCS

Rivian 

CCS

Nissan Leaf

CHAdeMO (older models)


Even with adapters, compatibility depends on:

  • Charger software
  • Vehicle firmware
  • Adapter verification 
  • Charging protocol support

Always ensure the connector locks securely before attempting to start the charging session. 

  1. Inspect the Connector for Damage or Dirt

Charging connectors experience thousands of plug cycles. Before blaming the station, inspect: 

  • Bent Pins
  • Dirt
  • Sand
  • Damaged locking mechanism 

Even a small amount of debris can interrupt communication between the charger and vehicle. A failed handshake between charger and vehicle is one of the most common reasons the charger shows ‘connected’ but never begins delivering power.  

  1. Restart the Charging Session 

Many public chargers experience temporary software communication errors.

Try this sequence: 

  • Stop the session
  • Unplug
  • Wait 30-60 seconds
  • Plug back in firmly
  • Restart charging 

This forces both the charger and vehicle to establish a new communication handshake. Industry troubleshooting guides identify this as one of the highest-success fixes for stalled charging sessions. 

  1. Check Your Vehicle Settings

Sometimes the charger is working properly. The problem is inside your vehicle. Look for: 

  • Scheduled charging enabled
  • Maximum battery limit already reached
  • Charging paused
  • Battery preconditioning active
  • Software updates running 

Tesla owners frequently discover that scheduled charging prevents immediate charging. 

Many non-Tesla EVs have similar settings through their mobile apps. 

  1. Verify Payment or App Authorization 

Public chargers often need: 

  • Mobile app login
  • RFID card
  • Credit card authorization 
  • Plug & Charge authentication 
  • Membership verification 

If authorization fails: 

  • Log out and back in 
  • Check payment method
  • Confirm mobile internet connection 
  • Restart the app
  • Try contactless payment instead

Backend payment failures are one of the leading reasons otherwise healthy chargers refuse to begin charging. 

  1. Watch for Error Codes

EV chargers now usually provide valuable diagnostic information. 

Examples include: 

Error

Possible Cause

Communication Error

Vehicle handshake failure

Ground Fault

Electrical safety issue

Connector Fault

Damaged cable

Authentication Failed

Payment problem

Charger Offline

Network issue

Thermal Protection 

Overheating 


Do not ignore these messages. Take a photo before calling customer support. Many operators can remotely reset the charger using the station ID. 

  1. Try Another Stall Before Leaving 

This may be the simplest solution. Many charging locations contain various independent charging cabinets. One charger may have: 

  • Damaged cable
  • Failed cooling system
  • Software fault
  • Payment thermal issue

Another stall only a few feet away may work perfectly. Switching stalls is often faster than driving several miles away to the next charging station. 

Should You Contact Customer Support? 

Yes. 

Every public charging station displays:

  • Customer support number
  • Station ID
  • Charger number 

Support teams can often: 

  • Restart the charger remotely
  • Verify network connectivity
  • Confirm any ongoing maintenance
  • Recommend another charger nearby 

Many charging issues are software-related rather than hardware failures. 

When to Switch the Charging Station?

Move to another charging location if: 

  • Multiple restart attempts fail
  • The charger repeatedly shows any hardware fault
  • The connector is visibly damaged
  • The station has no power
  • Support confirms the charger is offline
  • Every stall reports the same fault 

There is a very little value in repeatedly retrying a charger with confirmed hardware failures. 

Real Case Scenario

Imagine you are driving through South Florida on Interstate 95. You stop at a DC fast charger with 18% battery remaining. 

The charger displays: Connected

But power still remains at 0 kW. 

Instead of immediately driving somewhere else, you should: 

  • Reinsert the connector
  • Restart session 
  • Check scheduled charging 
  • Verify payment authorization 
  • Move to Stall 2 

Many drivers successfully begin charging after switching stalls or restarting the communication handshake, avoiding unnecessary detours. 

Florida EV Drivers: Things to Keep In Mind

South Florida continues to see rapid EV adoption, specifically among Tesla and luxury EV owners. During holidays, hurricane season, or major travel weekends, charger demand can spike, making reliability and planning even more important. 

For drivers in Boca Raton and surrounding areas, planning ahead can help reduce unexpected delays in charging: 

  • Check charger status before departing
  • Keep multiple charging apps installed
  • Have both NACS and CCS compatibility (where applicable)
  • Avoid arriving with less than 10% battery whenever possible
  • Identify backup charging locations along your route

If you are visiting Boca Raton, the EV charging resources available through Diamonds by Raymond Lee can make charging stops more convenient while you browse luxury jewelry or explore the area. 

What Is The Best Way to Charge An Electric Car While Traveling 

The best way to charge an electric car on long trips is to combine preparation with flexibility: 

  • Use reliable charging networks
  • Monitor live charger availability 
  • Precondition the battery before DC fast charging 
  • Arrive with 10 to 20% battery for optimal charging speeds
  • Carry compatible adapters if your vehicle supports multiple standards
  • Check alternative stations before your battery becomes critically low
  • Follow the eight troubleshooting checks above before abandoning a charger or whole station

This approach minimizes downtime, improves charging efficiency, and also helps ensure a smoother and stress-free journey. 

Conclusion 

A public EV charger that won’t start does not always mean ‘it is broken.’ Many failures from communication handshakes, payment authorization, connector seating, or temporary software issues. With systematic checking the status of charger, connector compatibility, vehicle settings, payment authorization, and alternative stalls, you can often solve the problem without moving to another charging station. 

For Florida EV owners, especially those who are traveling through Boca Raton, understanding how public charging infrastructure works is just as important as knowing where to charge. Following these best practices can reduce range anxiety, improve charging success, and ensure that you always find the best way to charge an electric car; safely, efficiently, and with confidence. 

Frequently Asked Questions (FAQs)

1. Why does my EV recognize the charger but not start charging?

This usually happens when the charger and your vehicle fail to complete the communication handshake. It can also be caused by payment authorization issues, scheduled charging settings, battery temperature, or a temporary software fault. Disconnecting and reconnecting the cable often resolves the issue.

2. How long should I wait before deciding a public EV charger isn't working?

Wait at least 2–5 minutes after connecting, especially at DC fast chargers. Some networks take additional time to authenticate your payment, communicate with your vehicle, and initialize the charging session. If nothing happens after troubleshooting, try another charging stall.

3. Can extreme weather affect public EV charging stations?

Yes. High temperatures can reduce charging speeds as chargers and batteries activate thermal protection. Heavy rain generally does not prevent charging, but flooding, lightning-related outages, or damaged equipment can temporarily take stations offline.

4. Is it safe to unplug and reconnect an EV charging cable multiple times?

Yes. Public charging connectors are designed for repeated use. If the first attempt fails, safely unplugging and reconnecting the cable can help establish a new communication session between the charger and your vehicle.

5. Why do some public chargers deliver slower charging speeds than advertised?

The maximum advertised power (such as 150 kW or 350 kW) depends on several factors, including your vehicle's charging capability, battery state of charge, battery temperature, charger load sharing, and local electrical capacity. Most EVs only achieve peak charging speeds under ideal conditions.

6. Should I always choose a DC fast charger over an AC charger?

Not necessarily. DC fast chargers are ideal for road trips and quick top-ups, while AC chargers are better for longer parking periods at hotels, shopping centres, workplaces, or destinations where your vehicle will remain parked for several hours.
