The invention discloses a charging and discharging control device and method of a mobile power source. After a control instruction is received, whether direct current voltage input from a charging and discharging port meets a preset charging condition or not is judged, and if yes, a charging control signal is sent. When the charging control signal is received, direct current input from the charging and discharging port is received to charge a battery of the mobile power source, and the mobile power source is in a charging mode. If the direct current voltage input from the charging and discharging port does not meet the charging condition, a discharging control signal is sent. When the discharging control signal is received, boosting processing is carried out on the input direct current then the current is output to the charging and discharging port, the battery of the mobile power source is discharged, and the mobile power source is in a discharging mode. The charging and discharging control device and method of the mobile power source control the battery of the mobile power source to be charged or discharged according to the direct current voltage input from the charging and discharging port, the mobile power source is not simultaneously in the charging mode and the discharging mode, work turbulence of an inner circuit system of the mobile power source is avoided, and the use stability of the mobile power source is improved.
Description
Technical field [0001] The present invention relates to the technical field of mobile power supplies, in particular to a charging and discharging control device and method of mobile power supplies. Background technique [0002] The mobile power supply is a portable charger that integrates power supply and charging functions. It has the characteristics of large capacity, multi-purpose, small size, long life, safety and reliability, and can be used for mobile phones, digital cameras, MP3, MP4, and handheld computers anytime and anywhere. , Pocket game consoles and other digital products power supply or standby charging functional products. [0003] At present, the mobile power supply on the market has at least one discharge port for power output and a charging port for charging input for the mobile power supply. The charging and discharging function of the mobile power supply is realized by selecting different ports. Under normal circumstances, the discharge port of the mobile power...
