Abstract
A diagnostic technique for determining whether the degradation of a rechargeable battery is normal or abnormal is provided. A device for determining whether the degradation of a rechargeable battery is normal or abnormal comprises a device for measuring a degradation indicator of a rechargeable battery, a device for determining the usage quantity of the rechargeable battery, and a device for comparing the usage quantity with a reference usage quantity in the case where the measured degradation indicator exceeds a reference degradation value.
Claims15
An apparatus comprising:
- a battery pack including a memory apparatus that stores data indicating usage history of the battery pack;
- and
- an adapter adapted for coupling to the battery pack, the adapter including a reading means for reading the data stored in the memory apparatus when the battery pack is coupled to the adapter, and a displaying means for displaying the data read by the reading means so that a user of the battery pack can learn the use history of the battery pack.
