Gently warm frozen connectors rather than forcing them
Keep connectors in holsters when not in use to prevent moisture accumulation
Consider a connector cover for additional protection in severe weather

Proper cable management between charging sessions—using built-in holsters or cable management systems—reduces strain on the cable and helps extend its lifespan.

3. Checking Connections and Cables

The electrical connections of your charging station are critical to both performance and safety. Regular inspection of these components helps prevent charging interruptions and potential hazards.

Examining External Connections

Start by assessing the visible connection points of your charging system:

Connector Inspection:

Check the charging connector for bent or damaged pins
Verify that the connector fits properly in your vehicle inlet without looseness
Inspect rubber seals or gaskets for deterioration
Look for discoloration of pins that might indicate overheating

Holster or Dock Connection:

Ensure that the connector seats properly in its holster when not in use
Verify that any locking mechanisms function correctly
Check that weather seals make proper contact

Cable Condition Assessment:

Run your hands along the entire cable length, feeling for any internal damage not visible from the surface
Check for any unusual stiffness or softness that might indicate internal deterioration
Pay special attention to points where the cable enters the charging station and connector
Ensure that strain reliefs at both ends are intact and functioning properly

These checks are particularly important for outdoor installations or chargers that experience frequent use.

Internal Connection Security

While internal components typically require professional inspection, be aware of signs that might indicate connection problems:

Warning Signs:

Intermittent charging failures or unexplained interruptions
Circuit breaker trips during charging sessions
Unusual noises such as buzzing or clicking from the charging unit
Warm spots or hot areas on the charger casing

For hardwired units, the connection to your home's electrical system should be professionally inspected annually to ensure terminal screws remain tight and there are no signs of overheating at connection points.

Cable Management Best Practices

Proper handling of charging cables significantly extends their lifespan:

Daily Handling Tips:

Avoid sharp bends or kinks when storing the cable
Use proper cable management systems rather than letting cables rest on the ground
Don't hang excessive weight from the cable or connector
Avoid driving over cables, which can cause internal damage not immediately visible

Storage Recommendations:

Use the provided holster or dock between charging sessions
Coil cables loosely rather than tightly wrapping them
Keep cables off the ground when possible to prevent moisture exposure and tripping hazards
Consider a cable management system if your charger doesn't include one

Proper cable management is not just about longevity—it also prevents safety hazards like tripping or strain-related damage that could compromise electrical insulation.
