CELL VOLTAGE BALLANCING CONTROL METHOD OF BATTERY MANAGEMENT SYSTEM

摘要

PURPOSE: The control method which can be efficiently proceed the voltage balancing about each cell of the battery management system of the vehicle using the electrical energy is offered. CONSTITUTION: The control method for the cell voltage balancing of the battery management system comprises the difference of the step. Two cell voltages distinguish whether difference is less than the standard value or not of two cell voltages arbitrarily selected between a plurality of cell voltages is the comparison reference the fixed the first phase reference domain and the step distinguish whether it belongs among the second section reference domain to a domain or not.
