According to the state council concerning the adjustment of industrial products production license management directory and try out the decision of the simplify examination and approval procedures "(Guo fa (2017) no. 34), the electric bicycle products from the production license to implement mandatory product certification (CCC certification) management, started on August 1, 2018.

According to the state council concerning the adjustment of industrial products production license management directory and try out the decision of the simplify examination and approval procedures "(Guo fa (2017) no. 34), the electric bicycle products from the production license to implement mandatory product certification (CCC certification) management, started on August 1, 2018.

At present, has confirmed to electric bicycle 3 c certification unit five are: China quality certification center (CQC), RGL certification center co., LTD. (CCAP), Beijing light united certification center (CCLC), Guangdong quality inspection institute, Shenzhen quality inspection, and certification and inspection qualified institutions across the country only two, Guangdong, Shenzhen quality inspection, quality inspection hospital respectively.

It is understood that the Guangdong inspection institute is one of the Guangdong province electric bicycle 3 c certification and testing of the major institutions, mainly to undertake the government supervision and spot checks of industry and enterprise entrusted test work actively. In 2017, Guangdong quality inspection institute selective examination, 77 companies in the province 83 batches of electric bicycle products. After inspection, found that the 6 companies production batch product is unqualified, unqualified products are found at a rate of 7.2%.

According to the state council issued a new decision, electric bicycle products CCC certification to the GB17761-2018 as the test standard. This standard is important components of storage the battery. Is there any requirement? Guangdong inspection today (Guangdong province pledges inspect bureau directly under the CPC unit, battery products in Guangdong province selective examination undertake unit) with all of you to answer this question.

1. This standard 4.4 provisions:

Electric bicycle in addition to conform to the requirements of the provisions of this standard, the vehicle and parts (such as battery, car charger, etc.) also should comply with the safety requirements of relevant national standards, industry standards. The battery electric bicycle now use, mainly two kinds of lead acid battery and lithium ion battery.

Application in the national standard of electric bicycle lead-acid battery for: GB/T22199-2008: an electric moped in sealed lead-acid battery; Industry standard is: QB/T2947.1-2008: electric bike with battery and charger part 1: sealed lead acid battery and charger. Lithium ion battery haven't corresponding state, the industry standard for: QB/T2947.3-2008: electric bicycle battery and charger part 3: lithium-ion battery and charger .According to the principle of national standards for similar products in the industry standard, so electric bicycle use lead-acid batteries should meet the requirements of the standard GB/T22199-2008, lithium ion batteries to meet the requirements of the standard QB/T2947.3.

2. This standard 6.3.4.2 maximum output voltage of the battery:

Electric bicycle battery should be less than or equal to the maximum output voltage 60 v.7.4.4.2 from this standard test method for understanding, the maximum output voltage here refers to the open circuit voltage of battery when battery fully charged.

3. This standard 6.3.4.3 tamper-proof battery:

Electric bicycle batteries tamper-proof should satisfy the following requirements

A) battery is fixed in the battery box, storage battery and battery box of reasonable matching, battery box with battery box installation position reasonable matching, prevent change battery capacity and voltage;

B) battery and battery box wall the biggest gap is less than or equal to 30 mm, and do not shake;

C) electric bicycle shall not obligate extension on-board battery interface;

D) the electric bicycle can not have a peripheral battery tray;

From the above requirements analysis: a) and b) requirement is for battery manufacturers, battery manufacturers need to consider when the design.

4. The appendix A of this international standard. 2 battery main technical parameters:

The capacity (Ah), and nominal voltage (V).
