Abstract

The invention provides a charging method. At least two power supply units in a charger are controlled to supply electricity to at least two charging units in electronic equipment, so that the at least two charging units in the electronic equipment respectively charge batteries in the electronic equipment. By the method, the charger can provide at least two power supply current to the electronic equipment. Correspondingly, the electronic equipment also comprises a plurality of charging units; the plurality of charging units can respectively charge the batteries on the basis of at least two power supply current; each charging unit only needs to obtain relatively low power; various charging units can realize charging of the batteries with relatively high power as a whole; in the rapid charging process, various charging units only need to provide relatively low power under the premise of ensuring the charging efficiency; and relatively low heat is generated, so that a charging module does not generate a violent temperature rise.

Description

technical field [0001] The invention relates to the field of electronic equipment, and more specifically relates to a charging method, a charger and a charging module. Background technique [0002] With the development of electronic technology, the demand for fast charging is becoming stronger and stronger in the daily use of electronic equipment, and various fast charging technologies emerge in an endless stream. The essence of this fast charging is to convert the current provided by the external charger into a larger current. Charge the battery. [0003] Such as figure 1 Shown is a schematic diagram of fast charging in the prior art, the charger 101 provides 12V / 2A charging power for the mobile terminal 102, and the charging IC (integrated circuit, integrated circuit) 103 in the mobile terminal performs power conversion, and converts it into the battery charging required The charging current is 4.35V / 4A, and the charging current is output to the battery 104 to complete t...
