Patent number: 11858354Abstract: An emergency disconnect circuit for use with a high-voltage (HV) bus of a battery electric system, e.g., aboard a mobile system, includes a pyrotechnic switch and a manual switch. The pyrotechnic switch configured irreversibly opens in response to an electronic triggering signal to disconnect an HV battery pack from the HV bus in a first manner. The manual switch is arranged on a low-voltage (LV) bus in series with and between the pyrotechnic switch and an LV power supply. Transition of the manual switch from an open position to a closed position connects the LV power supply to the pyrotechnic switch. This causes the LV power supply to discharge the triggering signal to the pyrotechnic switch. When used aboard a mobile system, an electronic monitoring unit generates the triggering signal in a second manner in response to a threshold impact event.Type: GrantFiled: April 11, 2022Date of Patent: January 2, 2024Assignee: GM Global Technology Operations LLCInventors: Li-Pen John Ho, Calvin Goodman, Rajesh Nagappala
