Laptop battery such as should be insulated between the poles of metal dust or copper with aluminum foil membrane perforation burr, resulting in micro short circuit. former situation is most serious, will directly cause a short circuit and a lot of heat production, resulting in some of the electrolyte vaporization, stretch battery case. addition, there is a special situation, the power charger or laptop due to special reasons, and instantly to the lithium battery provides high voltage / high current due to severe overcharge charging voltage suddenly rose from 12.6V 12.9V or higher, then there will be a high charging current generation, the battery internal circuit moves cut off the charging current, but part of the lithium battery charging overvoltage and overcurrent protection function design is weak, it may result in damage to the battery protection IC to protect and damaged so that the laptop battery, the overcharge after pole piece over the needle -like crystals of lithium metal, the pierce point lead to a number of micro short circuit, causing the battery temperature is gradually increased until the end of battery explosion and fire occurred, this is the main reason for many laptop battery "hot" plus cover layer umbrella from the point of view of the battery protection mechanisms, the charging part of the front of the battery pack, the traditional chip manufacturers provide solutions mostly played the role of the precise control of the charging voltage and charging current, Acer laptop battery over-voltage and over-current control does not provide the appropriate solutions so that the protection of the battery pack is completely dependent on the battery itself, such as the overcharge protection, over-discharge protection, overcharge current protection, over-discharge current protection, overheat protection and so on. "> According to the analysis, the lithium battery explosion is nothing less than caused by a short circuit or overcharge, most likely kinds of lithium battery manufacture, there are security risks can occur at any time because of the manufacturing process itself is flawed, leaving the product,Laptop battery such as should be insulated between the poles of metal dust or copper with aluminum foil membrane perforation burr, resulting in micro short circuit. former situation is most serious, will directly cause a short circuit and a lot of heat production, resulting in some of the electrolyte vaporization, stretch battery case. addition, there is a special situation, the power charger or laptop due to special reasons, and instantly to the lithium battery provides high voltage / high current due to severe overcharge charging voltage suddenly rose from 12.6V 12.9V or higher, then there will be a high charging current generation, the battery internal circuit moves cut off the charging current, but part of the lithium battery charging overvoltage and overcurrent protection function design is weak, it may result in damage to the battery protection IC to protect and damaged so that the laptop battery, the overcharge after pole piece over the needle -like crystals of lithium metal, the pierce point lead to a number of micro short circuit, causing the battery temperature is gradually increased until the end of battery explosion and fire occurred, this is the main reason for many laptop battery "hot" plus cover layer umbrella from the point of view of the battery protection mechanisms, the charging part of the front of the battery pack, the traditional chip manufacturers provide solutions mostly played the role of the precise control of the charging voltage and charging current, Acer laptop battery over-voltage and over-current control does not provide the appropriate solutions so that the protection of the battery pack is completely dependent on the battery itself, such as the overcharge protection, over-discharge protection, overcharge current protection, over-discharge current protection, overheat protection and so on.
