Abstract

The invention discloses a charger, a charging circuit thereof, and a charging control circuit. A voltage acquisition circuit acquires a current voltage of a battery, and a current acquisition circuit acquires a current charging current of the battery; the charging control module determines the voltage required to be output by a switching power supply according to the current voltage and the current charging current of the battery, and adjusts a feedback signal received by the switching power supply according to the voltage required to be output by the switching power supply, so that the switching power supply outputs the voltage required to be output; and the switching power supply is used for charging the battery. Therefore, the output of the switching power supply can be adjusted without a battery charging management chip, so that the multi-section charging of the battery is realized, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of battery charging, in particular to a charger, a charging circuit and a charging control circuit thereof. Background technique [0002] With the development of the times, energy storage technology is a strategic support for the transformation of future energy structure and the transformation of power production and consumption patterns. Driven by the development of energy storage technology and commercialization trends, batteries, as one of the protagonists, have received widespread attention. [0003] As an energy storage product, batteries inevitably need to be charged during recycling. If the charging is unreasonable and the chemical properties are not effectively charged, the service life and utilization rate will be greatly reduced, resulting in premature battery scrapping. Not only reduce the use value of the product itself. At the same time, because the battery is a heavily polluting product, it is difficu...
