Embodiment Construction

[0053] The following will be combined with Figures 1 to 11 The present invention is further described, but it should not be used to limit the protection scope of the present invention. For the convenience of description and understanding of the technical solution of the present invention, the orientation words used in the following description are all subject to the orientation shown in the drawings.

[0054] Please refer to figure 1 , figure 1 A flow chart of a flexible follow-up intelligent charging method is provided for an embodiment of the present invention. Such as figure 1 As shown, the flexible follow-up intelligent charging method includes the following steps:

[0055] S1. Charge the battery with the input pre-charging current until the battery voltage value is greater than the cut-off voltage value during discharge, and end the pre-charging phase;

[0056] In this step S1, since the secondary battery is over-discharged or placed for a long time, the active mate...

Abstract

The present invention discloses a flexible follow-type intelligent charging method and a charging device. According to the time sequence, the method comprises a pre-charging stage, a first constant-current charging stage, a constant-voltage and constant-current pulse charging stage, a first constant-voltage charging stage, a second constant-current charging stage, a second constant-voltage charging stage and an equalization charging stage. Based on the flexible follow-type intelligent charging method and the charging device, the state of a battery can be monitored in real time. Meanwhile, according to the power receiving capability of the battery at each stage, charging voltage and current parameters can be actively changed, so that the entire charging process can be automatically implemented. Therefore, the common problems in the prior art, such as the undercharging and overcharging conditions of secondary batteries, the excessively high temperature rise, the excessive gassing and the like during the charging process, can be solved. As a result, a larger amount of electric quantity can be charged during the charging process. Meanwhile, the single use time and the actual service life of a battery are prolonged.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a flexible follow-up intelligent charging method and a charging device. Background technique [0002] Secondary batteries can be repeatedly charged and discharged, have good energy storage characteristics, are widely used in industrial production and civil transportation, and can gradually replace the use of fuel to achieve the purpose of reducing emissions and environmental protection. For example, electric forklifts, electric vehicles and other environmentally friendly electric vehicles are equipped with lead-acid batteries or lithium-ion batteries in large quantities. However, users in the market generally report two problems: one is that the battery is charged frequently, and it needs to be recharged after a short period of time after each charge; the other is that the actual service life of the battery usually only reaches 1 / 2 of the design life or even shorter , far...
