Abstract

The invention discloses a charging control device and method, and the device comprises an obtaining module which is used for obtaining the temperature of a cell and a preset total charging current corresponding to the temperature of the cell in a timing manner; a first distribution module which is used for obtaining the temperature of charging chips when the total charging current is greater than a preset current, and distributing the total charging current to the charging chips according to the temperature of the charging chip, wherein the number of the charging chips is not less than two. The device and method can enable the total charging current to be uniformly and reasonably distributed to all charging chips, achieves the effective control of the distribution of the total charging current, and reduce the heating during charging.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a charging control device and method. Background technique [0002] Currently, mobile terminals generally provide a rechargeable battery for power supply. When the mobile terminal is charging, one or more charging chips generally control the charging current. Since the battery capacity of the mobile terminal is constantly increasing, the charging current during charging also increases accordingly, and high current charging will cause the heat generated by the mobile terminal to increase during charging, and the temperature of the mobile terminal will rise. Effective control of charging current distribution can easily damage the battery or cause safety accidents. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [000...
