  • Publication number: 20200209316
    Abstract: A new method for iteratively identifying parameters of an equivalent circuit model of battery, including the steps of: Firstly, dividing the model parameters into two parts, and the parameters in the first part are set to initial values, and the ones in the second part are identified with a least square method. Secondly, determining whether the obtained values of the second part meet the requirements of the equivalent circuit model of battery. If the requirements are not met, the parameters that do not meet the requirements in the second part are set to zeros. Then, the parameters in the first part are identified with the least square method. Otherwise, the ones in the first part are directly identified with the same method. Terminating the iteration process until all the parameters meet the requirements.

  • Publication number: 20200169097
    Abstract: A modularization system and a method for battery equalizers based on multi-winding transformers. By the inverse-parallel connection of the secondary sides of the odd and the even multi-winding transformers, the balancing in battery modules and between the odd and the even groups is realized based on forward conversion, and the balancing between the odd and the even groups and the automatic demagnetization for the transformers are realized based on flyback conversion. By only using a pair of complementary control signals, the direct, automatic and simultaneous balancing from any battery cell to any battery cell in the battery strings can be realized, thereby greatly improving the balancing efficiency and speed, and effectively improving the consistencies between the battery cells. The system has the advantages of high balancing efficiency, fast balancing speed, small size, low cost, high reliability, easy modularization, simple control, and nonuse of voltage detection circuits and demagnetizing circuits, etc.
