A sixteen-series power lithium iron phosphate battery matrix equalization control device and method

Abstract

The invention relates to a 16 series power lithium iron phosphate battery matrix equalization control device and method. The device is composed of a battery condition data collecting unit, a bidirectional programmable control data processing unit, a single battery state information matrix generating unit, a single battery information matrix verification control unit and an equilibrium switch matrix control unit. A 16 series power lithium iron phosphate battery pack is connected with the exteriors of the battery condition data collecting unit and the equilibrium switch matrix control unit. The beneficial effects are that, a plurality of data collecting ports adapted to battery pack networks are composited, which meets the further cascade communication and equalization control requirements of a plurality of battery packs. Battery heterogeneous condition data is subjected to charge homogeneous processing, generated matrixes and verification matrixes are constructed and stored according to battery test characters, battery pack information matrixes after verification can be identified intelligently, locally-judged equalization information is transmitted to the equilibrium switch matrix control unit, and the accuracy, precision and efficiency of equalization control is raised.

Description

technical field [0001] The invention relates to the technical field of a power lithium iron phosphate battery management system, in particular to a sixteen-series power lithium iron phosphate battery matrix equalization control device and method.

Problems solved by technology

[0004] At present, the prediction of the state of charge of the sixteen-series power lithium iron phosphate battery is only based on directly collecting the voltage, current and temperature data of the single battery for the analysis of the state of charge of the single battery. The balance control only considers the state of the single battery, and Does not include the individual difference performance of the battery pack inconsistency during information collection. In order to achieve this goal, a comprehensive dynamic working condition device and a balanced control method for accurately predicting power lithium iron phosphate lithium batteries are indispensable
