Abstract

The invention relates to a control method of solar clothes charging current, which comprises the following steps that: detecting outputted power of a solar battery; detecting dischargeable quantity and electromotive force of a built-in battery; detecting chargeable quantity and electromotive force of an external battery; solving power balance equations set; and charging the external battery according to the calculated charging current of the external battery. The invention also relates to a control device of the solar clothes charging current, which comprises a detection module, a calculation module and a charging module. Due to the adoption of the control method and the control device, the external battery can be charged within a minimal time.

Description

technical field [0001] The invention relates to the technical field of solar charging, in particular to a method and device for controlling charging current of solar clothing. Background technique [0002] In recent years, with the development of flexible solar cells, solar charging technology has been gradually applied to the traditional clothing field. Clothing provided with a solar charging device helps to solve the problem of charging outdoors or in emergency situations. [0003] In the prior art, the battery charging method is generally a constant voltage charging method or a constant current first and then a constant voltage charging method, and a pulse charging method is also used. Due to the continuous source of electric energy, these charging methods do not need to consider the utilization efficiency of electric energy, and generally adopt a larger or preset charging current or charging voltage until the charging task is completed. [0004] However, for solar clot...
