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 outlines a battery control system and a battery pack configuration that implements the monitoring method described. The system continuously measures differential voltages across contactors and ensures their proper functioning by setting threshold values for comparison. By monitoring the state of health of contactors before any switching process and transmitting warning signals when necessary, the method aims to enhance the safety and efficiency of battery packs used for delivering electrical energy to electric drive units.
