With the popularization of electric vehicles and the construction of charging facilities, the waterproof performance of electric vehicle charging cables has become an important consideration. In order to ensure the safety and reliability of charging cables in wet environments, relevant standards and test methods have been developed. The following will introduce some common waterproof performance test standards for electric vehicle charging cables.

1. IP rating standard: IP (Ingress Protection) rating is a common international standard for evaluating the dustproof and waterproof performance of electronic devices.The IP rating consists of two numbers, the first number indicates the dustproof rating and the second number indicates the waterproof rating. For example, IP67 indicates that a device is fully dustproof and water resistant to immersion in water up to 1 meter deep for 30 minutes. In waterproof performance testing of charging cables, the IP rating standard is usually referred to for evaluation.

2. Hydrostatic test: Hydrostatic test is a commonly used test method to evaluate the waterproof performance of charging cables. During the test, the charging cable is placed in a certain depth of water, a certain water pressure is applied, and it is observed whether there is water seepage or water leakage in the cable. The test results can determine whether the waterproof performance of the charging cable meets the requirements.

3. Leakage current test: Leakage current test is a method to evaluate the insulation performance of charging cable, which also indirectly reflects its waterproof performance. During the test, the leakage current in the cable is measured by applying a certain voltage. If the leakage current exceeds the specified safety range, it indicates that there is a problem with the insulation performance of the cable, which may lead to a decrease in waterproof performance.

4. Salt spray test: Salt spray test is mainly used to evaluate the waterproof performance of charging cables in corrosive environments. During the test, the charging cable is exposed to a foggy environment containing salt, and the cable surface is observed for corrosion, oxidation and other phenomena. Salt spray test can simulate the marine environment or bad weather conditions, to assess the corrosion resistance and waterproof performance of the cable.

OMG' has been in the field of electric vehicle cables for nearly 30 years of research and development and production experience, and has always maintained a high demand for the quality of charging cables, implementing performance testing and industry certification for each product. Over the years, OMG' has been committed to providing customers with new energy charging technology solutions that meet their actual needs.OMG' charging cables are not only waterproof, but also have the advantages of being soft, oil-proof, acid and alkali resistant, abrasion-resistant, and resistant to dragging. It should be noted that different regions and countries may have different standards and test methods. When choosing charging cables, we suggest referring to the relevant local standards and regulations to ensure that the cables chosen meet the requirements of waterproof performance.
