1. A battery management apparatus, comprising:
a voltage measuring unit configured to measure a voltage of a battery at every preset voltage measurement cycle;
a communication unit configured to output voltage information for the voltage measured by the voltage measuring unit at every preset communication cycle;
a power unit configured to provide an operation power to the communication unit when the communication unit operates;
an environment information measuring unit configured to measure environment information including at least one of ambient temperature and humidity of the power unit; and
a control unit configured to:
receive the measured environment information from the environment information measuring unit,
judge whether the power unit is operable based on at least one of the received environment information, a capacity of the power unit, and a consumed current and a communication time consumed for the communication unit to output the voltage information, and
control an operation of the communication unit according to a judgment result about whether the power unit is operable,
wherein the control unit is configured to calculate a diagnostic coefficient for the power unit based on the environment information.
