Samsung To Implement 8 Point Battery Safety Check After The Note 7 Disaster

The mystery behind the explosive Samsung's Galaxy Note 7 devices has finally been unveiled. The company has announced that faults in the battery were the reason behind the Note 7 disaster and from now on they will be implementing an 8 point battery safety check to ensure the reliability of the upcoming devices. Samsung, at a press conference confirmed it and also updated the information on their official website. More than 2.5 million Note 7 devices were recalled after they started to overheat and explode while charging. The 8-point battery safety check feature is expected to tackle such issues and ensure nothing like that happens with the upcoming Galaxy devices, especially the S8.

Not only profit, but Samsung has also lost its brand value in recent times. Note 7 has contributed a major part in that. After the incident, the engineers at Samsung, have re-designed the manufacturing process to tackle the shortcomings and from now on the batteries will be thoroughly tested and checked to ensure the safety of the user. This checking process has been coined as the 8 point safety check and include the following sequential steps –

8 Point Safety Check

  • Durability test – This test will check the durability of the batteries by studying their behavior at extreme temperatures, during overheating, etc. They will also undergo nail puncture test and battery compression test to check whether they explode or not when subjected to variable pressure.

  • Visual Inspection - It involves inspection of the battery via human eye to check whether certain standard guidelines are fulfilled or not.

  • X-Ray Test- Abnormalities which are not visible to the naked human eye can be analyzed using X-rays. This test will help to detect any anomalies which are present inside the battery.

  • Charge and Discharge Test – The battery undergoes several cycles of continuous charging and discharging to ensure the longevity of the device.

  • TVOC Test – Rechargeable batteries have several volatile organic compounds (VOC) and TVOC test reduces the probability of leakage of such compounds.

  • Disassembling Test- This test involves disassembling the battery to check its quality. Stress is given on battery tab welding and insulation tape conditions.

  • Accelerated Usage Test – Simulations are done assuming accelerated consumer usage scenario which unveils minute but important details like battery life, overheating, etc.

  • Delta OCV Test – This is the final stage where the battery is being monitored for any sudden change in voltage during the manufacturing process. Such devices are eliminated from the assembly line, if found to be faulty.

Hence, it is clear that the company has taken major steps to avoid manufacturing failures after the Note 7 recall. Though, such steps will cause delay in the launch of several upcoming devices, the future releases will be devoid of battery defects. The newest device in-line is the Samsung Galaxy S8 and only the time will be able to tell whether it will end up following the same fate as that of S7.
