From detection to customs clearance: The whole process of UAV battery CB certification is disassembled

As the "heart" of the aircraft, the UAV battery mainly provides power support for multi-rotor, fixed-wing and other models. At present, the mainstream products are mainly lithium polymer batteries, which have the characteristics of high energy density and fast discharge efficiency, and can meet the battery life needs of different scenes such as aerial photography, mapping, and agricultural plant protection. With the annual growth rate of the global UAV market exceeding 15% (source: Statista 2023), battery safety and international certification have become the focus of the industry.

Why do drones need CB certification?

CB certification as the International Electrotechnical Commission (IECEE) issued a "technical pass", can achieve "one test, multinational recognition". Through the certification of battery products can directly obtain the EU CE, Japan PSE and other 54 member states access qualification, to avoid repeated testing generated tens of thousands of dollars of costs. More importantly, the certification process will systematically detect 23 safety indicators such as overcharge protection and short-circuit protection of the battery, greatly reducing the risk of accidents such as spontaneous combustion and high-altitude power failure.

Certification application list

1, basic documents: enterprise business license, product specifications (including cell model/capacity/size parameters)

2, technical documents: circuit schematic, BMS protection board test report, UN38.3 transportation safety certificate

3. Sample preparation: Provide 3 sets of unpackaged cell modules and complete battery packs

4, auxiliary materials: product label design draft (need to include rated voltage, warning signs and other elements)

CB certification process

1. Pre-evaluation stage (3 working days) : technical parameter review and test plan formulation

2, laboratory testing (15-20 working days) : including thermal shock, extrusion test, high-altitude simulation and other extreme environment experiments

3. Report review (5 working days) : CB test certificate issued by IECEE certification body

4. Follow-up: Assist enterprises to complete the supplement of different provisions in different countries

Certification brings core values

In 2023, Amazon installed 12,000 uncertified drone batteries under the platform, and directly lost more than 10 million dollars. Products that pass CB certification not only get the priority of customs clearance, but also improve the bargaining power of overseas channels by more than 30%. After a head manufacturer in Shenzhen obtained certification, the re-purchase rate of its products in the German e-commerce platform increased by 58%.

In the current fierce competition in the global UAV market, CB certification is not only the "golden key" to open the international market, but also the authoritative endorsement of product quality. It takes about 45 days from document preparation to certificate obtaining. You are advised to start the certification plan six months in advance. Choose to cooperate with institutions that have experience in testing drone products, which can effectively avoid the risk of rework technical documents, so that your battery products can go smoothly in the international market.
