Maintain the electromagnetic radiation protection of electric vehicle chargers

To maintain the electromagnetic radiation protection of electric vehicle chargers, one can start from multiple aspects such as product selection, usage norms, environmental optimization, technological upgrades, and daily maintenance. The following are specific suggestions:

First, product selection

Select qualified products: Purchase and use certified charger products that meet safety standards. These products are designed in strict accordance with electromagnetic compatibility requirements. By adopting technical means such as shielding, filtering and grounding, the generation and leakage of electromagnetic radiation are effectively reduced, ensuring that the radiation level is far below the safety limit stipulated by the state.

When choosing a charger, you can refer to the radiation data provided by the product certification and the manufacturer. This information can usually be found in the product specification sheet or the official manual, which is helpful for consumers to make informed decisions.

Second, usage norms

Maintain an appropriate distance: When using a charger, try to keep a certain distance. Especially for sensitive groups such as pregnant women and children, they should try to avoid prolonged close contact with the charger. The intensity of electromagnetic radiation is inversely proportional to the distance. Increasing the distance can effectively reduce the impact of radiation.

Avoid prolonged exposure: Do not stay in the charger for a long time during peak charging hours. It is best not to stay in the car while charging to reduce radiation exposure time.

Third, environmental optimization

Rational layout of charging facilities: When planning the layout of charging facilities, scientific principles should be followed to avoid setting up too many chargers in densely populated or sensitive areas (such as hospitals, schools, etc.), so as to reduce the cumulative effect of electromagnetic radiation.

Enhance ventilation: Ensure good ventilation in the charging environment. Open the car Windows or activate the air conditioning ventilation system at appropriate times to reduce radiation accumulation.

Fourth, technological upgrading

Adopt shielding technology: For special areas or sensitive equipment, electromagnetic shielding measures can be taken, such as using shielding materials like metal plates and metal nets, to reduce the leakage and transmission of electromagnetic radiation.

Optimize circuit design: Shield and ground the key circuits to suppress the occurrence of electromagnetic noise. Meanwhile, optimize the on-board electronic and electrical system and adopt soft-switching technology to reduce the influence of transient electromagnetic fields.

Use high-efficiency filters: Install high-efficiency filters in the charger to reduce the impact of electromagnetic pulses on on-board electronic devices.

Fifth, daily maintenance

Regular inspection: Regularly inspect and maintain the charger to ensure it is in good working condition. If any abnormal situation is detected, such as a sudden increase in radiation values or abnormal heating of the equipment, it should be dealt with promptly to prevent the enhancement of electromagnetic radiation.

Timely replacement: For aged or damaged chargers, they should be replaced in a timely manner to avoid using inferior or substandard products and reduce the potential risk of electromagnetic radiation.
