Abstract

The present invention provides a charging method and a charging device. According to the embodiment of the present invention, the method comprises the steps of detecting the temperature and the voltage of a target charging battery; determining a target temperature range within which the temperature is; when the voltage of the target charging battery is less than a preset first cut-off voltage, adopting a continuously changing pulsating current to charge the target charging battery, wherein within the same time, the charging amount of adopting the pulsating current to charge the target chargingbattery is greater than or equal to the charging amount of adopting a target constant current charging current value matching the target temperature range to charge the target charging battery, and the valley point current of the pulsating current is less than the target constant current charging current value. According to the present invention, the charging time of the target charging battery can be shortened effectively, at the same time, the probability that due to the polarization, the anode potential of the target charging battery declines to a lithium analysis potential, so that a safety problem occurs can be effectively reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a charging method and a charging device. Background technique [0002] With the development of the communication technology, the functions of the mobile terminal become more and more abundant, and the operating load of the mobile terminal also increases accordingly, resulting in shorter and shorter standby time of the mobile terminal. Therefore, the battery, as a carrier of energy supply for the mobile terminal, has been paid more and more attention in the application field of the mobile terminal. [0003] The current charging method mainly includes two stages of constant current charging and constant voltage charging. Specifically, when the battery voltage is lower than a threshold voltage, the battery is charged by the constant current charging method until the battery voltage reaches the above threshold voltage, and the constant current charging method is used to charge...
