Abstract

The invention discloses a charger, its charging circuit and a charging control circuit. The current voltage of the battery is collected by the voltage acquisition circuit, and the current charging current of the battery is collected by the current acquisition circuit; the charging control module is based on the current voltage of the battery and the current charging current. The charging current determines the required output voltage of the switching power supply, adjusts the feedback signal received by the switching power supply according to the required output voltage of the switching power supply, and makes the switching power supply output the required output voltage; the switching power supply is used to charge the battery . As a result, the output of the switching power supply can be adjusted without the need of a battery charging management chip, thereby realizing multi-stage charging of the battery and reducing costs.

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...
