China News Service, Guangzhou, November 24th (Reporter Xu Qingqing) The reporter learned from the Guangdong Provincial Consumer Council on the 24th that the Guangdong Provincial Consumer Council and Dongguan Consumer Council have recently carried out a comparative test of electric bicycle products, and compared 20 mainstream brands and Models of electric bicycles (including the batteries and chargers attached to the vehicle, all of which are lithium-ion batteries) were tested, and only 8 of them were rated with a star rating or above.
It is understood that as of 2021, the number of electric bicycles in my country has reached 325 million.
This time, the focus is on testing the vehicle's speed limit, short-circuit protection, fire performance and other indicators.
The test results show that in the short-circuit protection test items, 13 models meet the standard.
In the test items of electrical clearance, creepage distance and solid insulation, 10 models meet the national standard.
In the battery overcharge protection test project, 20 models meet the national standard.
In the speed limit test item, the speed of 3 models can be tampered with, and the maximum speed exceeds the maximum speed limit (25km/h) after the speed limit is released; when the speed of 1 model exceeds 25km/h when the electric power assist function is used, the vehicle speed exceeds 25km/h. , The motor does not stop the power output.
The 17 samples have good waterproof performance and insulation performance in wet state.
In the fire performance test items, 19 models reached the national standard.
10 samples failed the product consistency verification.
The discharge test results of the lithium-ion battery on the vehicle show that the effective working time of 7 sample batteries is lower than the nominal capacity of the battery; The effective working time of the battery is low.
In the end, among the 20 samples, the samples of the nine brands and the five-star Diamond Leopard were rated as five-star; the samples of the two brands of Mavericks and Xiaodao were rated as four-star; Three stars; Xinri brand samples were rated two stars; other samples were not rated stars.
The Guangdong Provincial Consumer Council stated that from the overall point of view of the test, some products still have certain safety hazards in terms of anti-vehicle speed tampering, waterproof and fireproof performance, and short-circuit protection. Production or distributors assemble separately, there is a quality risk.
The problems of "shrinking" battery life, false labels, and illegal modification of some vehicles are more prominent.
The Guangdong Provincial Consumer Council reminds that once an "exceeding standard vehicle" causes a traffic accident, because some of its key technical indicators exceed the regulations of the electric bicycle standard, and its power performance is significantly higher than that of other non-motorized vehicles, it may be judged as a vehicle in judicial practice. Motor vehicles, so that the driver bears more responsibility in the determination of accident liability and subsequent compensation.
