Abstract
A battery management system includes: a contactor connected to a battery; a battery manager configured to output a control signal for controlling a state of the contactor to the contactor; a signal processor configured to receive a radio frequency (RF) signal generated during switching of the state of the contactor and to generate, based on the RF signal, a plurality of signal strength values respectively corresponding to a plurality of frequency bands; and a contactor state estimator configured to generate a state estimate value for estimating the state of the contactor by receiving the plurality of signal strength values and inputting the plurality of signal strength values into a pre-trained neural network model.

A battery management system comprising:
- a contactor connected to a battery;
- a battery manager configured to output a control signal for controlling a state of the contactor to the contactor;
- a signal processor configured to receive a radio frequency (RF) signal generated during switching of the state of the contactor and to generate, based on the RF signal, a plurality of signal strength values respectively corresponding to a plurality of frequency bands;
- and
- a contactor state estimator configured to generate a state estimate value for estimating the state of the contactor by receiving the plurality of signal strength values and inputting the plurality of signal strength values into a pre-trained neural network model.
A method of operating a battery management system comprising a contactor connected to a battery, the method comprising:
- outputting a control signal for controlling a state of the contactor to the contactor;
- receiving a radio frequency (RF) signal generated during switching of the state of the contactor;
- generating, based on the RF signal, a plurality of signal strength values respectively corresponding to a plurality of frequency bands;
- and
- generating a state estimate value for estimating the state of the contactor by inputting the plurality of signal strength values into a pre-trained neural network model.
