Document Type and Number:
WIPO Patent Application WO/2020/147178
Kind Code:
A1
Abstract:
Disclosed in the present invention are an electrical energy supply device and a MPPT control method. A master control MCU obtains a rising slope of an output voltage of a self-powered unit, and then looks up a table according to the rising slope to obtain a control parameter which enables the maximum harvesting power, so as to achieve small-current maximum power point charging control, overcome the technical problem in the prior art that the MPPT control method is not applicable to a small charging current, and achieve maximum power point charging control to an energy storage module by using a small current.
