Embodiment approach

[0057] Based on the above problems, this embodiment provides a solution capable of performing constant dq / dv charging on each battery module. Specifically, when the charging capacity reaches the preset capacity value required by the corresponding capacity step, the charging current and charging voltage need to be adjusted. As an implementation, the calculation method of the first charging current and the first charging voltage in the next capacity step can be: calculate the first charging voltage in the next capacity step according to the preset voltage adjustment index, and calculate the first charging voltage in the next capacity step according to the battery The internal resistance and the preset voltage adjustment index are used to calculate the first charging current in the next capacity step. Wherein, the preset voltage adjustment index may be set according to actual design requirements, which is not specifically limited in this embodiment.

Abstract

Embodiments of the invention provide a charging method and apparatus. The method comprises the steps of detecting charging information in the current capacity step length, wherein the charging information comprises a charging current, a charging voltage and charging capacity of a battery; judging whether the charging capacity reaches a preset capacity value or not; if the charging capacity reaches the preset capacity value, calculating a first charging current and a first charging voltage in the next capacity step length; and charging the battery based on the first charging current and the first charging voltage in the next capacity step length. By virtue of the charging method and apparatus, quick charging is realized while relatively long battery cycle life can be maintained.

Description

technical field [0001] The present invention relates to the technical field of charging, in particular to a charging method and device. Background technique [0002] The traditional fast charging method generally adopts the constant current and constant voltage fast charging method, and its disadvantage is that the cycle life of the battery is relatively poor. How to provide a charging scheme that can still show a good cycle life while fast charging is an issue in this field. A big problem for technicians. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings in the prior art, the purpose of the present invention is to provide a charging method and device, which can maintain a good cycle life of the battery while realizing fast charging. [0004] In order to achieve the above object, the technical scheme adopted in the preferred embodiment of the present invention is as follows: [0005] A preferred embodiment of the present invention p...
