Samsung Galaxy Note 7 fires and explosions were caused by defects within the battery. And also the company has currently discharged details of its investigation. The South-Korean technology conglomerate has additionally come back up with an eight-point precautions for its smartphone batteries. So as to make sure that such a situation doesn’t happen once more.
In line with the corporate, leading industry teams specifically UL, Exponent and TUV geographic area additionally conducted their own investigation into this issue. Therefore what precisely caused the issues with the Galaxy Note 7’s battery? Here’s an in depth explore Samsung’s explanation, in conjunction with ones given by the freelance investigation agencies.
Samsung Reveals Cause Of Galaxy Note 7 Fire :-
After months of testing, Samsung has finally unconcealed what caused its flagship Galaxy Note 7 to change state. At a group discussion, the Korean firm said that 2 separate faults with the battery were the reason behind the problems that saw some devices overheat and explode. Errors each in style and producing affected batteries by 2 completely different manufacturers.
Speaking regarding the issues, that forced Samsung to recall the smartphone. The corporate said: “Throughout the last many months, Samsung has endowed all of our efforts and substantial resources to finding the reason behind the Galaxy Note 7 incidents”.
“Our investigation examined each facet of the Galaxy Note 7 as well as hardware and software package, and connected processes, like assembly, quality assurance testing, and supply.”
Through a large-scale testing facility wherever around 700 Samsung researchers and engineers replicated the incidents by testing over 200,000 fully-assembled devices and over 30,000 batteries. Samsung finally finished the reason behind the problems.
Battery A issues
The work team found there was a difficulty with the planning in battery A. The problem: Not enough area to permit for the enlargement of its electrodes. Hence that happens throughout the conventional charge and discharge cycle of the battery. Samsung own rationalization is that “the negative electrode deflected within the higher right corner of the battery,” that is an abnormality within the style. In an exceedingly traditional battery, the positive and negative electrodes are properly separated. And also the negative electrode isn’t deflected neither is it touching the positive electrode. An additional contributory issue, consistent with Samsung was the tip of the negative electrode was incorrectly placed. Resulted in short-circuiting of the battery.
Samsung relied on a unique manufacturer for the second batch of battery once new units of the Note 7 were sent resolute replace the first ones. During this case, it’s like there have been issues with the producing quality and safety norms were unnoticed.
Samsung’s own report says there have been “high attachment blurs on the positive electrode,” that caused broken to the insulation tape and apparatus. And another time the positive electrode was touching the negative one, leading to the short-circuit. In addition, variety of batteries were missing the insulation tapes, that created the matter worse.
So what is Samsung doing to ensure this doesn’t happen again?
To reduce the probability of future battery failures, Samsung is implementing an 8-point Battery Safety make sure involves extra examination and testing. And up coaching for everybody concerned in handling batteries, each throughout assembly and shipping. It’s additionally adding extra space and brackets round the battery to safeguard it from crush connected failures, up the protection standards for the materials within the battery. And up its software package algorithms that control the battery charging temperature, current and period. Samsung confirmed that the forthcoming Galaxy S8 can like these new procedures and options. Noting that they’re going to not considerably impact the S8’s release date. Which is able to occur sometime once Mobile World Congress this year.
