In recent years of newcomer reports, there are often hot news about the portable power banks explosions. More and more consumers are more afraid of mobile power, so let’s analyze today, why does the mobile power explode?

    The explosion of portable power banks, in fact, we still need to start from the principle of battery analysis. The battery of the portable power banks refers to the part of space with electrolyte solution, metal motor, cup slot or other container or composite container to generate current. A device that converts chemical energy into electrical energy. When all the materials needed for the internal reaction are out of control, it will cause overheating or short circuit in an instant, and then cause explosion.

    Because the battery is its reactant and carries it when it is fully charged, the explosion is inevitable according to the law of conservation of energy. Therefore, in order to avoid the phenomenon of explosion, manufacturers must avoid the battery. In essence, if the portable power banks want to avoid explosion, we can solve the problem from two aspects. 1. Quality problem of cell. 2. Design of circuit board. If we want to solve the explosion problem of the portable power banks , we must have safe celland circuit board, among which circuit board and cell are the top priority of security protection, which can also be said to be the core technology of the whole the portable power banks.

    There are many manufacturers of high-end the portable power banks . They are equipped with protection circuit, temperature sensor and a full set of safety protection system inside the battery of the portable power banks. Therefore, compared with ordinary portable power supply, such protection system can effectively control the thermal runaway caused by overheating, and can also control the low voltage of battery pack to lock the battery and prohibit charging, Such behavior.

    So if we want to control the explosion of the portable power banks , we must solve it from the root.
