Multi-type laminated battery system based on multi-terminal parallel intelligent manager

Abstract

The invention belongs to the field of intelligent management of laminated batteries, particularly relates to a multi-type laminated battery system based on a multi-terminal parallel intelligent manager, and aims to solve the problem of lack of a multi-terminal parallel intelligent manager matched with multi-type laminated battery. Therefore, the problems that the output voltage of different typesof laminated batteries cannot be flexibly adjusted and each battery cannot output the maximum power are solved. The system comprises a laminated cell unit which comprises N solar cells which are arranged in a laminated mode and are of different structures; an intelligent manager which comprises direct-current electric energy converters which are connected with the solar cells in parallel in a one-to-one correspondence mode and convert electric energy of different voltages into set direct-current voltages consistent in size and polarity; and a control unit which performs power optimization to obtain the optimal output voltage, and performs on-off control of the corresponding direct-current electric energy converters to realize the maximum power point tracking of the solar cells. According to the invention, the combined lamination of different types of solar cells can be realized, the output voltage of each cell can be flexibly adjusted, and the output maximum power of each cell is ensured.

Description

Technical field[0001]The invention belongs to the field of laminated battery intelligent management, and specifically relates to a multi-type laminated battery system based on a multi-terminal parallel intelligent manager.Background technique[0002]At present, the mainstream structural forms of tandem solar cells include: One structural form is two or more solar cells stacked in series, that is, all batteries are connected in series, and the design of all batteries requires current matching, that is, each battery The output current is the same. No matter how many junction solar cells are stacked in this type of series stack connection, there is only a pair of positive and negative output terminals, that is, both ends, which is convenient for the access of the use terminals. Another structural form is the mechanical superposition of two or more solar cells, that is, all cells are connected in parallel, so that the voltage and current output of all cells are separated and independent. ...
