Summary: Relevance of the topic. Developing a new service of using the battery for electric vehicles.
The aim of the study is study the process of balancing voltage on battery cells when using different precisely modules for protecting cells
To achieve this goal, you must accomplish the following tasks:
– Experimental model of battery cell;
– Development of algorithm of balancing of cells;
– Development of research methodology;
Object of research: is a module for balancing battery cells.
Subject of research: is the study of the time taken to fully charge the battery from the given accuracy of the recharge circuit protection circuit.
Research methods: the following methods were used to solve the tasks: experimental simulation of charge characteristics and simulation of the algorithm of balancing cells using Excel.
Scientific novelty of the obtained results. The results show the characteristics of the battery charge based on the developed algorithm of balancing, due to which it is possible to create a battery with a large number of cells, which will be evenly balanced after the charge, with each cell will have a simple control circuit.
The practical value of the results obtained is the ability to compare the charging time spent on the battery with different precision circuitry for recharging. But assess the feasibility of using more accurate recharge control schemes.
