Samsung confirmed that the batteries caused the explosion of the Galaxy Note 7

Samsung revealed this week that the batteries were responsible for the explosions of your device Galaxy Note 7, as a result of an analysis carried out by the signature south Korean in respect of this problem which has cost more than 5,000 million dollars.

The head of the division of mobile telephony, Koh Dong-jin, presented in Seoul the results of the analysis after that for months the company will keep silence about the causes of the problem.

According to the findings of the study, carried out by Samsung and three other entities (consultants, american UL, and Exponent, and the German company of technical inspection and certification TÜV Rheinland), it would rule out the theory of those analysts who consider that is squeezed to the limit the design of the device.

In this sense, the existence of hardware or software problems would be seemingly discarded. The crisis of the Galaxy Note 7 kicked off just days after it began to be sold on the 19th of August, when the company received reports of batteries to fire during the loading process.

Finally, Samsung decided to stop manufacturing this model on the 11th of October, after offering 2.5 million people who had purchased the device apparatus replacement batteries manufactured by another supplier and that came back to give you problems.

The event generated an operating loss, according to estimates by Samsung, about 6.1 trillion of won (5.209 million dollars approximately).

The investigation has taken over a month to 700 technicians and engineers recreating in the four centers of manufacturing of the Galaxy Note 7 (one from South Korea, one in Vietnam and two in China) processes of loading and unloading, with about 200,000 coupled devices and some 30,000 lithium-ion battery.

This did not allow the stack to expand and contract properly during the charge and discharge cycles, making the electrode positive and the negative will be in contact and create a short-circuit.

battery replacement, manufactured by a Hong Kong company, presented no problems originally, even though they appeared after the company had to increase its production to unprecedented levels to meet the demand of Samsung.

This generated failures in the quality controls and made several units are manufactured incorrectly without membrane isolation, making it easier again to generate a short-circuit.

"Today, more than ever, we are committed to face to earn the trust of consumers," said Koh in the presentation, where it is said that the technology giant from south korea has already implemented a series of quality control processes with new protocols and a new specific test of eight points for the batteries.
