To having car gens for, charger carrying of the car in the car is very common thing. Nevertheless, on May 8, chongqing city Consumer's Committee releases " the car carries charger to compare an experiment to report " show, the car carries charger quality not to make a person be at ease so however, be in especially electric and safe respect, 5 sample stealthily " bad news report " .
According to introducing, bencibi relatively the car of the experiment carries charger sample, all protect committee staff member to be in Beijing with the identity of average consumer by rights and interests of Chongqing city consumer east the store on the net is bought, buy 10 sample book in all. Its brand is nominal have China for, Hua Weirong boast, ox, green couplet, Jia Lang, Netease, green gigantic can, PHILIPS, first 10 brands such as division, BMW, producing area involves and other places of Beijing, Shanghai, Shenzhen, Hangzhou. The price is top for BMW356 yuan / , lowermost is Jia Lang 29.9 yuan / . Among them, the price is in 6 of 100 yuan of above, 100 yuan 4 the following.
Microtherm job that experiments to carry charger to 10 cars quite, high temperature job, be able to bear or endure temperature change, be able to bear or endure intensity of temperature rise of face of damp and hot, crust, overvoltage, use up without laden energy, electrostatic discharge immunity to interference, radiate is annoyed, transient state is conducted annoy etc.
This second 10 example all are double USB interface, 10 sample book are only 3 example (China for, honorable, Jia Lang) have interface of USB of a standard, namely the output voltage with this nominal interface, electric current is worth place of standard of applicable YD/T 2306-2011 to list a requirement. Reason environment experiment is opposite only above of 3 charger " standard USB interface " the test undertakes accordance decides as a result.
Because climate of winter of our city summer is more outstanding, difference in temperature is opposite bigger, the temperature inside summerly overhead traveling crane can be as high as 50 ℃ above, the temperature inside winter car also can drop to zero, highest Yi Chao crosses the humidity in air 80% , because this car carries charger to get used to ability to what temperature, humidity changes, very important to broad consumer. But the result shows, in microtherm, high temperature, be able to bear or endure temperature change, and be able to bear or endure in the test of damp and hot, only China for, honorable test accords with standard requirement as a result, jia Lang checks a result not to accord with a standard to ask.
In the meantime, on electric safety performance, the test makes a person make a heart as a result. Electric safety performance, main from intensity of crust face temperature rise, overvoltage, use up without laden energy it is dangerous to wait for a respect to inspect a product to whether can produce electric safety, and the product is used up without laden power. In this second test, 2 example are in Jia Lang, ox the instant of car engine strike a light, the attaint after overvoltage checks. The circumstance is shut to fall in engine in the car, the car carries charger charging to the equipment such as the mobile phone the n performance that the oneself below the circumstance uses up is poorer. In 10 example green couplet, BMW, Jia Lang, green gigantic can 4 sample satisfy a standard to ask, 5 (China for, Hua Weirong boast, ox, PHILIPS, first division) example does not accord with a requirement. The product of Netease company tags his to have FM signal to blast off, blue tooth function, do not apply to YD/T 2306-2011 standard to ask, this project does not have this product standard accordance decides.
In addition, electromagnetism compatibility can be goodish. Among them, radiation infests a project in the test, green couplet, Netease, green gigantic can 3 example do not accord with a standard to ask, will affect circumjacent product (on the car other electron equipment) regular job.
Chief still says related Chongqing city Consumer's Committee, the nameplate of 10 example product of this second test and manual content are not complete. Netease cloud player all uses the electric norms information such as output voltage electric current without charger on the packing box of CM599A example, manual, trade catalogue, the electric norms information on the electric norms information on the DLP2015P product outer packing of PHILIPS and prototype airframe is conflicting.
