Application: Method and device for monitoring the state of health of a contactor (Patent ID: US20240201258A1)
The patent filed by Webasto SE describes a method for monitoring the state of health of contactors in a battery pack by measuring differential voltages across switchable contactors and determining their health based on these measurements. The method involves comparing the measured voltages with pre-set threshold values to assess the condition of the contactors and deliver information to control devices or users accordingly. Additionally, warning signals are generated if the measured voltages exceed warning threshold values, and the method includes steps to suppress switching of contactors in case of voltage anomalies.
Furthermore, the patent details the arrangement of contactors in the battery pack, the measurement of voltages in relation to reference potentials, and the generation of warning signals based on percentage thresholds of the pre-set voltage values. The method also involves continuous monitoring of contactors' health, setting of voltage threshold values, and transmitting warning signals to control devices or users. The patent also includes claims related to a battery control system for implementing the monitoring method, a battery pack configuration with switchable contactors, and a computer-readable medium storing instructions for executing the monitoring operations.
