1. A battery management device comprising:
a range setting unit configured to set a limited measurement range that limits a range for measuring a voltage of each of a plurality of batteries for a vehicle, and
a measuring unit configured to measure the voltage of each of the plurality of batteries within the limited measurement range,
wherein
the range setting unit sets the limited measurement range adjusted based on a voltage value of each of the plurality of batteries when the voltage value of each of the plurality of batteries is to be estimated, and
the range setting unit sets the limited measurement range based on a measurement value for the voltage of each of the plurality of batteries within an entire range when the voltage value of each of the plurality of batteries is not to be estimated.
