EV Charger Repairs and Fault Finding
EV charger fault diagnosis for failed charging, tripping, damaged equipment and communication issues
EV charger faults can sit in the charger, vehicle, electrical supply, protective device, app, network platform, cable or plug.
Safe diagnosis separates electrical faults from manufacturer, software or vehicle issues before repair or replacement is recommended.
Not every internal charger fault can be repaired by a general electrical repair; some need manufacturer parts, software support or replacement hardware.
B2E Electrical & Renewables Ltd is a family-run SELECT member based in Rosyth, supporting homeowners, businesses, landlords, fleet operators and operational premises considering EV charging across Fife and surrounding areas.

What EV Charger Repairs and Fault Finding Includes
Customers with an EV charger that is not powering on, not charging, tripping, overheating or showing faults.
The exact scope depends on the existing installation, the property or site conditions and the customer-safe information confirmed before work begins.
- Charger not powering on
- Vehicle not charging
- Intermittent charging
- Repeated tripping
- Communication faults
- Damaged tethered cable
- Water-ingress concerns
- Overheating
- Fault codes
- Electrical testing
Do not open charger equipment yourself. Internal faults may require manufacturer-approved parts, software support or replacement hardware.
Why the service may be needed
Charging failure
The car may connect but fail to charge because of charger, vehicle or supply issues.
Protective devices trip
RCDs, RCBOs or internal protection may be responding to a fault.
Physical damage
Cables, plugs, sockets and enclosures can become unsafe through damage or weather.
Connectivity problems
App, Wi-Fi or network issues may affect operation without being an electrical fault.
EV charger warning signs
Stop using equipment that appears unsafe, damaged, overheated or water affected until it is assessed.
- No power
- Repeated tripping
- Vehicle connects but will not charge
- Damaged tethered cable
- Water damage
- Overheating
- Fault codes
- App or Wi-Fi issues
Do not open charger equipment yourself. Internal faults may require manufacturer-approved parts, software support or replacement hardware.
Repair and diagnosis routes
Electrical diagnosis
Supply, protection, cable and connection issues are tested where accessible.
Manufacturer support
Internal hardware, software or warranty faults may need manufacturer involvement.
Replacement advice
A failed, obsolete or unsafe charger may be better replaced than repaired.
Vehicle or network checks
Some symptoms may sit outside the charger and need vehicle or platform support.
How We Complete EV Charger Repairs and Fault Finding
Each ev charger repairs and fault finding project has a service-specific scope, with more detail available in our shared electrical project process.
Step 1
Initial discussion
We confirm the ev charger requirement, who the work affects and the practical reason for the enquiry.
Step 2
Site assessment
The existing installation, access, likely cable routes and any constraints are reviewed before the scope is finalised.
Step 3
Scope and quotation
The quotation describes the agreed ev charger repairs and fault finding scope, known assumptions and exclusions.
Step 4
Planning and access
Dates, isolations, access arrangements and coordination with other trades or site users are agreed before work starts.
Step 5
Installation
The work is completed with attention to fault history, safe isolation, supply checks, protective-device testing, charger condition, manufacturer boundaries and retesting.
Step 6
Inspection and testing
New or altered electrical work is inspected and tested where required before handover.
Step 7
Certification and handover
Appropriate certification, labels, records and operating information are provided for the work within scope.
Regulations, Safety and Scope
Designed, installed, inspected and tested to the current edition of BS 7671 and applicable Scottish Building Standards requirements.
Earthing, protective devices, supply capacity, load management, external equipment suitability and manufacturer installation requirements are reviewed for the actual charger and site.
Charger apps, payment platforms, network services, vehicle software, manufacturer warranties, civil works and supply upgrades are confirmed separately where they sit outside B2E's electrical scope.
Benefits of EV Charger Repairs and Fault Finding
Clear fault separation
Electrical, vehicle, app and manufacturer issues are distinguished where possible.
Safer use decisions
Damaged or overheating equipment can be taken out of use pending repair or replacement.
Practical next steps
Repair, support or replacement routes are explained.
Reduced unnecessary replacement
Testing can avoid replacing a charger when the fault is elsewhere.

EV Charger Repairs and Fault Finding Questions and Answers
Why is my EV charger not working?
Possible causes include supply faults, charger failure, protective-device operation, app or network issues, cable damage or vehicle settings.
Why does the charger keep tripping?
A protective device may be responding to a real fault, overload, water ingress or equipment issue. Testing is needed.
Can a damaged tethered cable be replaced?
Sometimes, but availability and suitability depend on charger make, model and manufacturer parts.
Is the fault in the charger or the car?
Testing and symptom history help separate charger, vehicle and supply issues, but vehicle faults may need dealer support.
Can you diagnose app or Wi-Fi problems?
Basic connectivity context can be reviewed, but charger-platform and account support may sit with the manufacturer or network.
When should the charger be replaced?
Replacement may be more practical when the charger is obsolete, unsafe, water damaged, unsupported or repeatedly unreliable.
