Patent number: 11325493Abstract: Various systems and methods for controlling a maximum current threshold of a battery system within a vehicle are presented. The systems may include a battery module, one or more vehicle systems, a battery management system having a battery monitoring unit that monitors a current parameter, and a battery control system that receives the current parameter from the battery monitoring unit. The battery control system may be configured to identify a current event for the battery module, determine a duration of the current event, compare the duration of the current event to a plurality of time thresholds, determine the current parameter based on the duration of the current event, determine a maximum current parameter based on the duration of the current event and the current parameter, and control the one or more vehicle systems such that a current of the one or more batteries does not exceed the maximum current parameter.Type: GrantFiled: March 18, 2019Date of Patent: May 10, 2022Assignee: CHONGQING JINKANG POWERTRAIN NEW ENERGY CO., LTD.Inventors: Jun Hou, Min Tian, Chen-Yen Yu, Minghao Dai

Patent number: 11121654Abstract: Dynamic stability control for electric motors is provided. The system determines, for an electric motor of the electric vehicle, a slip frequency indicating a difference between a synchronous speed of a magnetic field of the electric motor and a rotating speed of a rotor of the electric motor. The system compares the slip frequency with a threshold. The system activates, responsive to the slip frequency greater than or equal to the threshold, a slip limiter to adjust a current command to generate an adjusted current command that causes a reduction in the slip frequency. The system deactivates, responsive to an external torque command less than a subsequent current command received subsequent to transmission of the adjusted current command, the slip limiter.Type: GrantFiled: September 30, 2019Date of Patent: September 14, 2021Assignee: SF MOTORS, INC.Inventors: Apoorva Athavale, Ruonan Zhou, Chen-Yen Yu, Yifan Tang

Patent number: 10641836Abstract: Various arrangements for determining the state of health (SOH) of a battery of an electric vehicle are presented. A first OCV of the battery of the electric vehicle may be determined. Coulomb counting on the battery of the electric vehicle may be performed to determine an accumulated capacity value following the first OCV being determined. A second OCV of the battery of the electric vehicle may be determined after performing the coulomb counting. A change in OCV value may be calculated using the determined first OCV and the determined second OCV. A slope value may be determined by dividing the accumulated capacity value by the change in OCV value. The SOH of the battery may then be determined using the slope value.Type: GrantFiled: February 6, 2019Date of Patent: May 5, 2020Inventors: Jun Hou, Min Tian, Chen-Yen Yu, Junzhe Shi, Saeed Khaleghi Rahimian, 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

Patent number: 9647583Abstract: A variable magnetization machine controller has a current command module, a magnetization module and a reducing current module. The current command module computes a vector current command in a dq axis based on a torque command. The magnetization module applies a magnetization control pulse to a d-axis current of the vector current command. Thus, the reducing current module applies a reducing current to a q-axis current of the vector current command based on the torque command and one of an estimated torque of the variable magnetization machine and a measured torque of the variable magnetization machine.Type: GrantFiled: June 28, 2013Date of Patent: May 9, 2017Assignees: Nissan Motor Co., Ltd., Wisconsin Alumni Research FoundationInventors: Takashi Fukushige, Chen-yen Yu, Robert D.
