When driving out, mobile phones, dash cams and tablets often run out of power, and the car power bank thus becomes a "mobile power bank". Whether it's a fast charging head plugged into a cigarette lighter or a multi-functional power supply with multiple USB interfaces, safety and compliance are crucial for such products connected to vehicle circuits, and the CB certification for vehicle power supplies is an important part of this.
I. Introduction to Vehicle Power Supply Products
The vehicle power supply mainly draws electricity through the 12V or 24V power interface of the vehicle to charge electronic devices. Common types include cigarette lighter chargers, car inverters (capable of converting to 220V household voltage), and power modules with integrated USB interfaces, etc. With the popularization of new energy vehicles, dedicated on-board power supplies that are compatible with the circuits of new energy vehicles are gradually increasing, with more diverse functions and higher requirements for safety standards.
Ii. Reasons for Applying for CB Certification
1. International mutual recognition advantage: CB certification is based on IEC international standards. After obtaining the certificate, when exporting to over 40 member countries such as Germany, France, and Japan, there is no need to conduct full-item tests repeatedly. Only local difference tests need to be supplemented, which can save time and costs.
2. Safety assurance function: CB certification will test the electrical safety, insulation performance, and overheat resistance of the product, which can prevent vehicle malfunctions or safety accidents caused by short circuits or leakage.
3. Compliance entry threshold: Many countries and regions use CB certification as a reference for the entry of imported electronic and electrical products. Without this certification, the products may not be able to be sold in the local market.
Iii. Certification Processing Procedures
1. Select an institution: Choose a qualified testing and certification body that can provide CB certification services.
2. Submit materials: Submit the prepared documents and samples to the institution and pay the certification fee.
3. Sample testing: The institution conducts electrical safety, electromagnetic compatibility and other tests on the samples in accordance with IEC standards. If the samples are not up to standard, the enterprise needs to modify them according to the rectification suggestions and re-test.
4. Issue certificates: After the test is passed, the institution will issue a CB test report and certificate.
5. Follow-up maintenance: When there are changes to the product design or key components, it is necessary to report to the institution in a timely manner and re-evaluate if necessary.
The CB certification for vehicle power supplies is not only a "pass" for products to enter the international market, but also an important boost for ensuring user safety and enhancing product competitiveness. For manufacturing enterprises, planning the certification process in advance can enable products to adapt to domestic and international markets more quickly.
