Publication number: 20230388261Abstract: Systems and method for determining a topic cohesion measurement between a content item and a hyperlinked landing page are presented. In one embodiment, a plurality of content item signals is generated for the content item and a corresponding plurality of signals are generated for the hyperlinked landing page. An analysis of the corresponding signals is conducted to determine a measurement of topic cohesion, a topic cohesion score, between the content item and the hyperlinked landing page. A cohesion predictor model is trained to generate the predictive topic cohesion score between an input content item and a hyperlinked landing page. Upon a determination that the topic cohesion score is less than a predetermined threshold, remedial actions are taken regarding the hyperlink of the content item. Alternatively, positive actions may be carried out, including promoting the content item to others, associating advertisements with the content item, and the like.Type: ApplicationFiled: April 18, 2023Publication date: November 30, 2023Applicant: Pinterest, Inc.Inventors: Andrey Dmitriyevich Gusev, Wenke Zhang, Hsiao-Ching Chang, Qinglong Zeng, Peter John Daoud, Jun Liu, Grace Chin, Zhuoyuan Li, Jacob Franklin Hanger, Vincent Bannister

Patent number: 11287479Abstract: A physics-based calendar life model for determining the state of health of a lithium ion battery cell. The model accounts for parasitic reactions on anode and cathode particles to accurately determine degradation of a battery. By incorporating electrolyte decomposition in a cathode, the present calendar model can predict capacity retention as well as the substantial rise of cell resistance at high state of charge (SOC) and temperatures. The present calendar model is a simple algorithm, utilizing only three parameters, and determines the capacity retention and resistance rise based on temperature, SOC and time.Type: GrantFiled: July 23, 2019Date of Patent: March 29, 2022Assignee: CHONGQING JINKANG POWERTRAIN NEW ENERGY CO., LTD.Inventors: Saeed Khaleghi Rahimian, Junzhe Shi, Wenke Zhang, Ying Liu, Mehdi Forouzan, Yifan Tang

Patent number: 11223073Abstract: Techniques described herein relate generally to determining and applying threshold discharging C-rates for battery cells in low temperature environments. To combat internal resistance within a battery cell at low temperature, heat may be generated within a battery cell via a high discharge C-rate. A higher discharge C-rate may cause more heat generation with a battery cell and the higher temperature may mitigate the low temperature environment. As a result of the heat generation, a battery cell's capacity may be increased. Techniques described herein may identify, for a particular low temperature (0 degrees Celsius and below), a threshold discharge C-rate that if a battery cell is discharged above the threshold, the effect of temperature rising would be more dominant than the effect of the internal resistance and more capacity would be obtained from the battery cell.Type: GrantFiled: February 28, 2019Date of Patent: January 11, 2022Assignee: CHONGQING JINKANG POWERTRAIN NEW ENERGY CO., LTD.Inventors: Wenke Zhang, Brennan Campbell, Ying Liu

Patent number: 10511050Abstract: Battery health is determined by estimating a battery anode capacity, battery cathode capacity, and cyclable lithium capacity. Determining electrode and lithium capacity may include determining anode and cathode open cell voltages (OCV) at the beginning of battery life, and estimating the full cell OCV from the individual (half-cell) OCV values. Once the beginning of battery life information is known, the state of charge (SOC) for a battery is measured during battery life. The SOC measurements may be captured at a plurality of different levels. The cathode capacity, anode capacity, and cycle mobile lithium capacity are then determined from the beginning of life OCV data and plurality of SOC data. The capacities can be used to detect degradation, and a battery management system can take steps to reduce further degradation based on the capacity values.Type: GrantFiled: December 31, 2018Date of Patent: December 17, 2019Assignee: SF Motors, Inc.Inventors: Saeed Khaleghi Rahimian, Sangwoo Han, Junzhe Shi, Wenke Zhang, Ying Liu, Jun Hou, Chen-Yen Yu, Yifan Tang
