Why does the phone explode while charging?

A number of phone cases exploded when charging, causing injury or death to people both in Vietnam and around the world, causing many people to be nervous and confused.

According to experts, the phone explosion when charging can come from many reasons but in general, there are two main causes are the battery or the charger .

Phone exploded due to battery

Modern lithium batteries are now particularly popular among smartphone manufacturers. However, the researchers say that standard lithium batteries still carry risks and can theoretically explode. This explosive reaction is called the process of evading the battery's heat when its internal temperature reaches the limit.

However, if the phone you buy is genuine, you can be assured because the manufacturer has integrated some safety features into the battery. In the worst case, when the temperature is too high, the battery will only cause the phone to stop working.

But that's in case the phone battery is still safe and the phone is not damaged inside. If the user drops or has the impact of damaging the phone, it will change the mechanical and chemical structure of the battery, breaking the inner cells. This could cause the battery to swell and potentially explode.

Charging a phone in too high a temperature can also cause the battery cell to burst and cause a fire.

Not only that, charging a phone at high temperatures can also cause the battery cell to burst and cause electronic short circuits. It can lead to thermal resonance and the battery will get hotter and lead to explosion. This can happen when you are playing graphic games too heavy while charging your phone, charging your phone at high temperatures .

Signs of an unsafe and damaged phone battery, if charging can cause explosions include bulging, deformed batteries, frequent hot phones, very low battery power, frequent power outages .

In case of explosion due to battery charging, the device will burn due to the direct contact with air of lithium. It will cause users if using the phone when charging experiencing minor injuries, skin burns and some other mechanical injuries. Phone explosions due to broken batteries are unlikely to cause fatalities for users.

Phone explodes due to charging

A few years ago, when answering the press, Dr. Phung Anh Tuan, Deputy Head of Department of Electrical and Electronic Equipment of Hanoi University of Technology Electrical Institute said that a quality-guaranteed charger must include a shoulder device. game of electrical isolation between the two input and output sections - ie convert high voltage 220V to low voltage 5V.

The majority of deaths from using a phone while charging are caused by the fact that chargers do not guarantee quality that could cause an electric shock.

This means, if your phone charger is genuine and meets safety standards, its output voltage is very low, can not cause burns or death. However, if the charger is not up to the quality, they will not meet the safety requirements for isolating the power supply or if they have a damaged internal insulation, the output can be connected to the input. This means that the output voltage will be the 220V voltage.

At that time, your phone has a high risk of explosion due to high voltage and users may also get an electric shock if touching it, causing injury or death. The majority of deaths from using a phone while charging are caused by the fact that chargers do not guarantee quality that could cause an electric shock.

Nearly all manufacturers will equip a charger with safety standards for users. However, when this charger fails, many people buy poor quality chargers, counterfeit, fake goods to use. This is not recommended because it may endanger your phone and yourself. To prevent this, buy a phone manufacturer's charger or at least from a reputable manufacturer, which has full safety quality standards. This will make you safer every time you use your phone while charging.
