Abstract
A battery contact failure detecting device includes a battery including a plurality of battery cells; a connecting part including at least one of a busbar, a contactor, and a fuse and connects the battery cells to each other; a sensor configured to measure a current and a voltage of each of the battery cells; and a processor configured to count a number of abnormal occurrences based on the current and the voltage measured by the sensor to detect a contact failure of the battery cells due to a short circuit or open circuit of the connecting part.
Claims16
A battery contact failure detecting device comprising:
- a battery comprising a plurality of battery cells;
- a connecting part comprising at least one of a busbar, a contactor, and a fuse and connects the battery cells to each other;
- a sensor configured to measure a current and a voltage of each of the battery cells;
- and
- a processor configured to count a number of abnormal occurrences based on the current and the voltage measured by the sensor to detect a contact failure of the battery cells due to a short circuit or open circuit of the connecting part.
A battery contact failure detecting method comprising:
- measuring, by a sensor, a current and a voltage of each of a plurality of battery cells;
- counting, by a processor, a number of abnormal occurrences based on the current and the voltage measured by the sensor;
- and
- detecting, by the processor, a contact failure of the battery cells due to a short circuit or an open circuit of a connecting part connecting the battery cells to each other based on the counted number of abnormal occurrences.
