How to clean the casing of an electric vehicle charger correctly

To ensure the normal function of the charger, extend its service life and avoid potential safety hazards, it is necessary to follow the scientific cleaning process. The following is the specific operation guide:

First, preparations before cleaning

Safe power-off

Operating requirements: Unplug the power plug of the charger to ensure that the device is completely powered off.

Risk avoidance: Avoid electric shock or short circuit, especially in damp environments, extra caution is required.

Second, cleaning steps

Surface dust removal

Operation method:

Use a soft-bristled brush or vacuum cleaner to clean the dust on the surface of the shell and the heat dissipation holes.

Focus on cleaning areas prone to dust accumulation such as charging ports and ventilation openings.

Example: Similar to cleaning the outer casing of a computer mainframe to prevent dust from entering the internal circuits.

Decontamination treatment

Light stains

Dip a microfiber cloth in a small amount of neutral detergent and gently wipe the surface of the shell.

Avoid the cleaning agent from seeping into the joints or crevices.

Stubborn stains

Use a damp cloth (wrung out until no water drips) to dip in the cleaner, wipe the affected area repeatedly and then dry it immediately.

Drying treatment

Operating requirements:

Thoroughly dry the outer shell with a dry cloth to ensure there is no residue.

Let it air dry naturally for at least 15 minutes (avoid direct sunlight).

Third, handling of special circumstances

Oil stains or stubborn stains

Method:

Use 70% isopropyl alcohol (alcohol) to dip a cotton swab, wipe the area locally and dry it immediately.

Avoid direct contact of alcohol with the plastic casing (which may cause brittleness).

Charging interface area

Operation taboos:

It is strictly prohibited to directly rinse the interface with liquid cleaners.

Only use dry compressed air or a soft-bristled brush to clean the dust at the interface.

Differences in shell materials

Plastic shell

Avoid using ammonia-containing cleaners (such as glass cleaners), as they may corrode the material.

Metal casing

Minor rust can be sanded with fine sandpaper and then coated with anti-rust oil. Severe rust requires the replacement of the casing.

Summary

Safety first: Make sure to cut off the power before cleaning to avoid the risk of electric shock.

Scientific material selection: Use neutral cleaners and soft tools to avoid damaging the shell.

Key protection: Pay special attention to the cleaning of areas prone to dust accumulation such as interfaces and heat dissipation holes.

Regular maintenance: Develop a cleaning plan based on the usage environment to extend the lifespan of the charger.

By following the above steps, the charger casing can be effectively kept clean, ensuring the stable performance and safe use of the device.
