A method and apparatus for diagnosing battery abnormality of an ecofriendly vehicle may include incrementing a count value based on a cell balancing starting voltage deviation which is a voltage deviation of a plurality of cells forming a battery module of the vehicle when a cell balancing mode for adjusting the voltage deviation of the plurality of cells starts and a cell balancing ending voltage deviation which is a voltage deviation of the plurality of cells when the cell balancing mode ends, storing the count value and the identifier or the identification number of the cell having the minimum voltage among the plurality of cells, and detecting cell abnormality based on the count value and the identifier or the identification number of the cell having the minimum voltage.
