Description

technical field [0001] The invention relates to the charging field, in particular to a battery charging system and a charging method thereof. Background technique [0002] With the rapid development of smart phones, more and more functions can be realized, and the supported screens are getting bigger and bigger, which leads to more and more power consumption of smart phones, and the battery life of smart phones is getting longer and longer. Short, in order to use the smart phone normally, it is necessary to charge the battery in the smart phone from time to time. The traditional charging technology includes switch charging and linear charging. Among them, the charging efficiency of switching charging is usually about 85%, and the charging efficiency of linear charging is usually At about 70%, both of them have the problem of high heat consumption. The traditional charging technology, no matter switch charging or linear charging, cannot support super-large current charging, s...

[0002] With the rapid development of smart phones, more and more functions can be realized, and the supported screens are getting bigger and bigger, which leads to more and more power consumption of smart phones, and the battery life of smart phones is getting longer and longer. Short, in order to use the smart phone normally, it is necessary to charge the battery in the smart phone from time to time. The traditional charging technology includes switch charging and linear charging. Among them, the charging efficiency of switching charging is usually about 85%, and the charging efficiency of linear charging is usually At about 70%, both of them have the problem of high heat consumption. The traditional charging technology, no matter switch charging or linear charging, cannot support super-large current charging, so it cannot realize fast charging of the battery, which in turn reduces people's interest in smart phones. Therefore, it is necessary to provide a charging method and a charging system to solve the above technical problems
