Publication number: 20240113514Abstract: Systems and methods are provided for a battery management system (BMS) having a protection circuit. In one example, a vehicle battery system may include the BMS, the BMS including a cutoff circuit electrically coupled to the protection circuit, and a battery pack, a positive supply line of the battery pack being electrically coupled to the cutoff circuit, wherein the protection circuit may include each of an input electrically coupled to a control input of the cutoff circuit, an output electrically coupled to an output of the cutoff circuit, and a control input of the protection circuit electrically coupled to the output of the cutoff circuit. In some examples, the protection circuit may further include a low-current leakage transistor configured to maintain the cutoff circuit in an OFF state upon detection of a reverse bias voltage. In this way, the protection circuit may mitigate unexpected switching ON of the cutoff circuit.Type: ApplicationFiled: December 13, 2023Publication date: April 4, 2024Inventors: Ke Xu, Weiwei Lin, Jiaping Zhang, Yue Li

Publication number: 20230253780Abstract: Systems and methods are provided for a battery management system (BMS) having a protection circuit. In one example, a vehicle battery system may include the BMS, the BMS including a cutoff circuit coupled to a short-circuit protection circuit, and a battery pack, wherein the short-circuit protection circuit may include a diode array, cathodes of the diode array being coupled to a positive terminal post of the battery pack and anodes of the diode array being coupled to a negative terminal post of the battery pack. In some examples, the cutoff circuit may further be coupled to a reverse bias protection circuit including a switchable current path arranged between a control input of the cutoff circuit and an output of the cutoff circuit. In this way, the vehicle battery system may be protected from unexpected voltage conditions via the BMS redirecting and dissipating excess current away from the cutoff circuit.Type: ApplicationFiled: April 18, 2023Publication date: August 10, 2023Inventors: Yue Li, Steve Gierlach, Weiwei Lin, Brian Large, Jiaping Zhang, Ke Xu

Patent number: 11663544Abstract: A method of early warning and risk assessment of incidents in a multi-tenant cloud environment is provided. The method includes: capturing a plurality of data metrics; automatically generating derived features from the plurality of captured data metrics; automatically selecting risk assessment features from the derived features and the captured data metrics; and predicting the risk of an incident in the multi-tenant cloud environment within a specified time window in the future and one or more possible root causes of the incident by applying the newly selected risk assessment features to a trained risk assessment model. The trained risk assessment model has been trained using machine learning techniques to predict the risk of an incident in the multi-tenant cloud environment within a specified time window in the future, provide an explanation of possible root causes of the incident, and assign a strength level to each possible root cause.Type: GrantFiled: January 28, 2020Date of Patent: May 30, 2023Assignee: salesforce.com, inc.Inventors: Jiaping Zhang, Ana Bertran, Elena Novakovskaia, Zhanara Amans, Garren Bellew, Philip Dolle

Publication number: 20230134412Abstract: A serial transmission controller for processing data transmissions between a memory and an external device is provided. The serial transmission controller includes a microcontroller, a scheduling unit, a transmission unit, and an interception control unit. The microcontroller obtains pipe data from the memory. The microcontroller reads a transfer request block from the memory according to the pipe data. The scheduling unit generates a transmission request according to the pipe data and the transfer request block. The transmission unit transmits a packet of the transfer request block according to the transmission request, and correspondingly generates a transmission response. When the interception control unit receives the transmission response, and the data length that has not been transmitted in the transfer request block is greater than 0, the interception control unit notifies the transmission unit to continue to transmit a next packet of the transfer request block.Type: ApplicationFiled: September 27, 2022Publication date: May 4, 2023Inventors: Jiaping ZHANG, Hongchao MA, Zhiqiang HUI, Lin LI
