| description | The issue of evaluating the efficiency of high-voltage batteries of electrified vehicles at low temperatures is considered. A technique is presented for selecting the electrochemical type of batteries for operation in regions with a cold climate, which includes experimental obtaining of the charge-discharge characteristics of high-voltage batteries under conditions of normal and low temperatures and their analytical study. As a result of testing the methodology, regression dependences were obtained that describe the processes of charge-discharge of batteries of various electrochemical types (Li-Ion, LiFePO4, LTO) as a function of temperature. In connection with the emergence of new electrochemical types of batteries with increased resistance to hypothermia, the proposed method will allow us to evaluate their effectiveness and fully use electric cars in regions with a cold climate.
The purpose of the study is to develop a methodology for selecting batteries for low-temperature operation of electric vehicles and hybrids based on an experimental study and comparison of results.
The method used is mathematical planning of the experiment, correlation-regression analysis of experimental data with the construction of mathematical models of charge-discharge.
Main results — a method for choosing an electrochemical type of battery for operation in regions with a cold climate was developed and tested.
The novelty of the study is represented by mathematical models that describe the change in the capacity of high-voltage batteries depending on temperature.
The direction of further research is the refinement of models, the study of the low-temperature properties of new and promising types of chemical elements of high-voltage batteries. |
