The invention discloses a control method and
system for a power
bank capable of switching charging power, and relates to the technical field of power banks, and the method comprises the steps: building a
data connection relation with a cloud platform of a power
bank renting operator; if the
Bluetooth information of the target
mobile phone sent by the cloud platform is received, establishing
data connection with the target
mobile phone; acquiring electrical parameters of a plurality of modules in the
mobile phone to obtain real-time
power consumption and defining the real-time
power consumption as a1; comparing the
power consumption accumulated value a1 with a pre-selected high power consumption standard threshold value; if the real-time power consumption is greater than a large power consumption standard threshold, determining that a preset hot risk condition is met, and switching a charging mode of the power
bank to a low-
power mode; obtaining interaction information input to the power bank by a user in the charging process; and if the
signal for resetting the charging power of the power bank appears in the interaction information, disconnecting the
data connection between the power bank and the mobile phone, and resetting the charging behavior of the power bank to be high power priority. The method and the device have the effect of reducing potential safety hazards when the power bank is used for charging.
