Abstract

The invention relates to the technical field of power supplies and discloses a self-adaptive quick charging device. The self-adaptive quick charging device comprises a processor, a current regulator,a voltage regulator, a first fuzzy controller, a second fuzzy controller, a charging main circuit and a battery clamp, wherein the processor is used for acquiring a battery-end voltage, a charging current and a battery temperature signal of a battery to be charged on the battery clamp, and outputting a control current and a control voltage. The self-adaptive quick charging device based on fuzzy self-adaptive PID (Proportion Integration Differentiation) has the advantages of good stability performance, short dynamic response time, fast charging speed and high efficiency and the like, and realizes intelligent and quick charging.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to an adaptive fast charging device. Background technique [0002] During the charging process of the battery, the change of the charging current with time follows the charging acceptance characteristic curve of the lead-acid battery. Any current exceeding this characteristic curve will not only fail to increase the charging speed, but will also cause hydrolysis, gas evolution, increased pressure and temperature rise. The charging current less than this characteristic curve is the acceptable charging current of the battery, but this prolongs the charging time. In the prior art, there is no effective charging method for lead-acid batteries, and the charging speed is slow and the efficiency is low. Contents of the invention [0003] The invention provides an adaptive fast charging device, which solves the technical problems of lack of an effective charging method for a lead-...
