Abstract
An electrically driven vehicle comprises a battery configured by connecting a plurality of cells in series; and a motor configured to transmit electric power to and from the battery. When an abnormality occurs in a cell voltage detection system configured to detect cell voltages of the respective cells of the battery, the electrically driven vehicle prohibits regenerative control of the motor. The electrically driven vehicle determines whether the battery is being charged, based on an open circuit voltage of a block that is comprised of at least two or more cells among all the cells constituting the battery. The open circuit voltage of the block is calculated from a voltage of the block and a battery current flowing in the battery.
