"I put my phone on the bedside table every night to charge it, and one charge is one night." Citizen Mr. Wang said that his mobile phone has just been bought for more than two months. It is a certain brand of smart phone, and the battery is a 3.7-volt lithium battery. After getting up early every day, I will find some heat in the back cover of the phone, but I don't care too much. In fact, there are not a few people who charge their phones all night like Mr. Wang.
As for why mobile phone batteries explode? Mr. Chen from a mobile phone store in Fengze Street in the urban area explained that most mobile phone batteries currently use lithium batteries. Lithium batteries usually explode due to several reasons. First of all, the battery itself is caused by the inside of the battery. There are defects; second, the battery is charged for a long time, and the current causes high temperature and high pressure, which causes hidden dangers; third, the mobile phone is placed next to high temperature or flammable objects.
[Charge a mobile phone, one charge is one night, which is very bad for the capacity and life of the battery." Mr. Chen reminded that the mobile phone should be placed in a place where heat is easy to dissipate during the charging process to avoid potential safety hazards, especially in emergency situations. Do not put the phone in a bed before going to bed, do not put the battery in a high temperature environment, do not violently hit or squeeze the battery, and avoid sun exposure during the charging process of the phone. Don't charge it in a low-temperature state; don't continue using it when the battery is deformed or swollen. If the mobile phone is found to be abnormal during charging, the power should be cut off immediately, and it should not be used again. Do not use the phone while it is charging.
Electric vehicles should be charged when 1/3 of the battery is left
In addition to mobile phones, many people also charge electric cars every day. The electric vehicle battery explodes or spontaneously ignites due to charging. How to correctly charge the electric vehicle battery?
A salesperson in an electric vehicle store on Zhongshan South Road in the urban area told the reporter that when the electric vehicle is left with 1/3 of its power, it is best to start charging, and do not wait for the power to be exhausted to recharge. It is best not to put the charger on the car. Long-term turbulence during driving will damage the electric car charger; try not to use fast charging, as fast charging will easily cause damage to the battery. In addition, the charging environment should be kept dry and clean.
Camera and MP4 are charged in a ventilated and easy-to-heat place
Various rechargeable electronic products are popular nowadays. In addition to mobile phones, there are also MP4, digital cameras, laptops, camcorders, etc. Mr. Chen reminded that when charging these small electrical appliances, it is best to plug the charger in a place with good ventilation and easy heat dissipation; use the charger to master the time, not "continuous combat", and unplug it once it is fully charged, not to mention it. Whether charging or not, plug the charger into the socket all day long. In damp weather, please pay attention to dusting all kinds of chargers to prevent the dust from absorbing moisture in the air and causing electric leakage.
