In order to enter the new commercial civilization of openness, transparency, sharing, and responsibility in major shopping malls, and to ensure the legitimate rights and interests of users, third-party certification organizations with CNAS and CMA qualifications are specially entrusted to test and certify the products of mall merchants. The mall has also launched product sampling inspection guidelines, that is, regularly sampling corresponding products and sellers based on channel sales, refunds, complaints and other data information. The sampling products are entrusted to a national legal third-party quality inspection organization to make judgments. Once product quality problems are found, Tmall Mall will conduct sanctions in accordance with regulations and publicize the results of sanctions. If the circumstances are serious, they will be directly reported to the industrial and commercial administration or even transferred to the public security organs. So how to handle the battery test report for the battery entering the mall? BCTC certification service

Qualification material requirements for batteries to enter Tmall

1. If the trademark is still in the acceptance stage, a list of operating products needs to be submitted. If the list contains products that need to pass national compulsory certification, it is necessary to provide the 3C certification of the product.

2. The following products need to provide quality inspection statements (each brand must provide at least one quality inspection statement issued by a third-party authoritative organization, and the content of the product inspection statement must include the brand name, product name, product model, and all necessary product Various test items), the necessary test items are as follows:

1. Power adapter:

The test items must include: label and clarification book review (including label scrubbing and content review), electric strength

2. Lithium battery:

The test items must include: discharge function, free fall, overcharge maintenance, short circuit test

3. Power bank:

The test items must include: symbols and clarifications to view, drop test, discharge function

Note:

1. The testing of power adapter and mobile power is based on GB4943, and the testing of lithium battery is based on GB18287;

2. After the merchants settle in, request to add brands and categories, and the specifications are the same as above. Tmall will conduct irregular inspections for businesses that have already settled in, please keep it for inspection.

Battery test statement

What are the battery test items?

According to the national standard of lithium battery: GB/T18287-2000, the test items of lithium battery include appearance, discharge function, high and low temperature function, charging persistence ability, cycle life; heat resistance, vibration resistance, bumping resistance, and free fall environment Adaptability; safety functions for overcharge maintenance, faulty power maintenance, and short circuit maintenance; safety functions for heavy object impact, thermal shock, overcharge, and short circuit; storage functions, etc. The following focuses on the test conditions and specifications in terms of power release function, high and low temperature function, cycle life, overcharge, overdischarge and short-circuit maintenance.

1. In terms of the discharge function test, the specification requires charging and discharging to the stop voltage at the specified charge-discharge rate under the condition of (20±5)℃, and the discharge time is not less than the specified value.

2. The function of high temperature and low temperature is tested at (55±2)℃ and (-20±2)℃ [for polymer lithium ion battery (-10±2)℃], and the battery will be taken out after the test. , Placed for 2h under the condition of ambient temperature (20±5)℃, the appearance of the battery should be no deformation or bursting. Comprehensive testing

3. The requirement for cycle life is to charge at 1C5A at ambient temperature (20±5) ℃ and discharge to the stop voltage, and place it for 0.5-1h before proceeding to the next charge-discharge cycle until the time of two consecutive discharges is less than 36min. , It is considered that the lifespan is stopped, and the cycle life of the battery should not be less than 300 times.

4. For over-charge, over-discharge and short-circuit maintenance, the battery is required to not burst, fire, smoke or leak under specified operating conditions.
