The waterproof and dustproof grades of electric vehicle chargers and their purchasing relationship

The relationship between the water and dust resistance levels of electric vehicle chargers and their selection

First, the definition and standards of water and dust resistance grades

The water and dust Protection level of electric vehicle chargers is usually indicated by the IP (Ingress Protection) code, which is set by the International Electrotechnical Commission (IEC). The IP code consists of two digits:

The first digit: Dust protection level (0-6), indicating the protection capability against solid particles (such as dust).

The second digit: Water resistance grade (0-9), indicating the protection capability against liquids such as water.

IP65 indicates a dust resistance rating of 6 (completely dust-proof) and a water resistance rating of 5 (water-resistant).

Second, the relationship between water and dust resistance levels and the selection of chargers

The usage environment determines the level requirements

Indoor or sheltered places: such as garages and underground parking lots, a lower grade (such as IP44) can be selected to meet the basic requirements of dust and splash protection.

Outdoor or harsh environments: such as open-air parking lots, areas with heavy rain and dust. It is recommended to choose a high grade (such as IP65 or above) to ensure long-term reliability.

Safety and durability

Dust prevention: Dust entering the charger may cause short circuits in the internal circuits or poor heat dissipation, affecting its lifespan.

Waterproofing: Water ingress may pose an electric shock risk or cause equipment damage, especially in damp or rainy areas.

Regulations and Standards

Different countries and regions have clear requirements for the waterproof and dustproof levels of public charging facilities. For instance, European standards require that public charging piles at least meet IP54 standards.

When purchasing, it is necessary to confirm whether the charger complies with local regulations and industry standards.

Maintenance cost

Chargers with high-grade water and dust resistance have lower maintenance costs as they reduce the need for faults and repairs caused by environmental factors.

Third, purchasing suggestions

Clarify the usage scenarios

Indoor: IP44 or above.

Outdoor: IP65 or above.

Extreme environments (such as by the sea, deserts) : Consider IP67 or IP68.

Pay attention to brands and certifications

Choose well-known brands and ensure that the products have undergone strict testing and certification.

Check whether the product has passed relevant certifications such as CE, UL and IEC.

Consider additional functions

Some chargers are equipped with intelligent temperature control, overload protection and other functions, further enhancing safety and durability.

Budget and Cost Performance

Chargers with high-level water and dust resistance are usually more expensive, but in the long run, their reliability and low maintenance costs may be more cost-effective.

Fourth, Summary

The water and dust resistance level of an electric vehicle charger directly affects its safety, durability and applicable scenarios. When making a purchase, one should comprehensively consider factors such as the usage environment, regulatory requirements, brand reputation and budget to select the appropriate waterproof and dustproof grade. For outdoor or harsh environments, it is recommended to choose a charger with IP65 or higher to ensure long-term reliable operation.
