A battery diagnostic apparatus includes a storage, a battery state manager, and a battery diagnostic device. The storage includes battery state history data including periodic battery charge state information. The battery state manager stores the battery state history data in the storage and retrieves the stored battery state history data. The battery diagnostic device is configured to determine a usage pattern depth of discharge in a state of charge based on the battery state history data, and predicts a remaining life of a battery based on the battery state history data and the usage pattern depth of discharge.
A battery diagnostic apparatus comprising:
A battery diagnostic method comprising:
The battery diagnostic method of claim 17, wherein the discharging the battery by driving the electric component further includes stopping an operation of an low voltage DC-DC converter that reduces a high voltage and provides a voltage to the battery.
The battery diagnostic method of claim 17, wherein the allowing of the battery to be discharged by driving the electric component is performed based on confirming that the state of charge of the battery is 50% or more than 50%.
