Abstract
A battery management device includes: a detection circuit to detect state information indicating a state of a battery; and a control circuit to monitor the state of the battery based on the state information detected via the detection circuit, and control a function associated with the battery based on a result of the monitoring. The control circuit is further to open a load break switch electrically connected between the battery and a power conversion device in response to detecting that the battery is in an abnormal state during charging or discharging of the battery.
Claims20
A battery management device comprising:
- a detection circuit configured to detect state information indicating a state of a battery;
- and
- a control circuit configured to monitor the state of the battery based on the state information detected via the detection circuit, and control a function associated with the battery based on a result of the monitoring,
- wherein the control circuit is further configured to open a load break switch electrically connected between the battery and a power conversion device in response to detecting that the battery is in an abnormal state during charging or discharging of the battery.
A battery management system comprising:
