Problems solved by technology

The charging power of the existing mobile power supply is determined by the charger. If the charger used is not the original charger, the relevant parameters of the charging current that can be provided will change, or the external power supply itself will fluctuate, and the change of the charger will cause the charger to fail. If the power is higher than the power of the mobile power supply, it is possible to 'charge bad' the mobile power supply; and the fluctuation of the external power supply itself also affects the service life of the mobile power supply

Abstract

The invention discloses a mobile power source having a charge management function. The mobile power source comprises a charging interface, a charging circuit, a charging battery and a CPU. The charging interface is used for an external power supply to be accessed. The charging circuit comprises a voltage and current detection circuit and a voltage regulation circuit. The input end of the voltage and current detection circuit is connected with the charging interface and is used for detecting charging voltage and working current of the charging circuit. The CPU is connected with the voltage and current detection circuit and the voltage regulation circuit and used for controlling the voltage regulation circuit to work under the highest power of the mobile power source according to the charging voltage and the working current. The input end of the voltage regulation circuit is connected with the output end of the voltage and current detection circuit. The output end of the voltage regulation circuit is connected with the charging battery and used for charging the charging battery under the highest power of the mobile power source. By the adoption of the scheme, the influence on a mobile terminal of external current change is eliminated, and mobile power source damage caused by too high charging power and the influence on the service life of the mobile power source of the changing external power supply are avoided.

Description

technical field [0001] The invention relates to power supply technology, in particular to a mobile power supply with charging management. Background technique [0002] With the widespread use of electronic equipment, the use of mobile power is becoming more and more common. The charging power of the existing mobile power supply is determined by the charger. If the charger used is not the original charger, the relevant parameters of the charging current that can be provided will change, or the external power supply itself will fluctuate, and the change of the charger will cause the charger to fail. If the power is higher than that of the mobile power supply, it is possible to 'charge bad' the mobile power supply; and the fluctuation of the external power supply itself also affects the service life of the mobile power supply. Contents of the invention [0003] The invention provides a mobile power supply with charging management to solve the damage to the mobile power suppl...
