Abstract
In a method for detecting an internal short of a battery, the method includes: measuring a voltage of a battery a plurality of times; and determining whether or not the internal short of the battery occurs based on a difference between a first voltage value of the battery during a first time period and a second voltage value of the battery during a second time period when the battery is in constant current charging, wherein the second time period is a time period after the first time period.
Claims42
A method for detecting an internal short of a battery, the method comprising:
- measuring a voltage of a battery a plurality of times;
- and
- determining whether or not the internal short of the battery occurs based on a difference between a first voltage value of the battery during a first time period and a second voltage value of the battery during a second time period when the battery is in constant current charging,
- wherein the second time period is a time period after the first time period.
A method for detecting an internal short of a battery, the method comprising:
- measuring a current of the battery a plurality of times;
- and
- determining whether or not the internal short of the battery occurs based on a difference between a first current value during a first time period of the battery and a second current value during a second time period when the battery is in constant voltage charging,
- wherein the second time period is a time period after the first time period.
A method for detecting an internal short of a battery, the method comprising:
- measuring a voltage and a current of the battery a plurality of times;
- determining whether or not the battery is being charged based on the voltage and the current of the battery;
- and
- determining whether or not the internal short of the battery occurs based on a difference between a first voltage value of the battery during a first time period and a second voltage value of the battery during a second time period after a threshold time elapsed from a charging termination time point of the battery,
- wherein the second time period is a time period after the first time period.
An apparatus for controlling a battery, the apparatus comprising:
- a measuring unit configured to measure a voltage and a current of the battery a plurality of times;
