Publication number: 20230208169Abstract: An Energy Management Unit (EMU) integrates the on-board charger (OBC) and battery management system (BMS) and optional DC-DC to behave like a lab based Electrochemical Impedance Spectroscopy (EIS) device.

Patent number: 11415635Abstract: A controller for use in a battery charging system includes processing circuitry configured to perform certain tasks during battery charging operations, and other tasks during operational use of the battery. During a charging operation, the controller receives a measured DC impedance of a propulsion battery measured by a battery data acquisition and monitoring subsystem, obtains a reference DC impedance of a hypothetical battery, and determines an impedance degradation factor of the propulsion battery using the measured DC impedance and the reference DC impedance. During operational use of the propulsion battery, the controller obtains an operational reference impedance of the propulsion battery, determines a real-time effective impedance for the propulsion battery based on the impedance degradation factor and the operational reference impedance, and generates a feed-forward parameter based on the real-time effective impedance.Type: GrantFiled: May 23, 2019Date of Patent: August 16, 2022Assignee: Tesla, Inc.Inventor: Anil Paryani

Patent number: 11378954Abstract: A multi-processor architecture for automated driving systems can be used to improve performance and provide design flexibility. For example, a multi-processor architecture can be used to implement command generation and safety functionality in different processors. The command generation processor can be a high performing processor compared with the safety processor. The safety processor can verify the safety of commands output from the command generation processor and provide additional I/O channels that are typically absent on high performing processors. Additionally, processing of some sensor data can be moved to expansion modules with additional processors to reduce bottlenecks and provide design flexibility for systems with different sensing requirements.Type: GrantFiled: June 28, 2017Date of Patent: July 5, 2022Assignee: Faraday&Future Inc.Inventors: Anil Paryani, Michael Hong, Aziz Umit Batur, Bibhrajit Halder, Hong S.

Patent number: 11299049Abstract: The present disclosure relates to a vehicle power system. In some examples, the vehicle power system can include a plurality of redundant low-power buses coupled to respective low-power batteries. The low-power buses can be powered by a vehicle battery having a higher voltage than the voltage of the low-power batteries by way of a DCDC converter, for example. In some examples, the DCDC converter can be coupled to the low-power buses via a plurality of switches included in an Auxiliary Voltage Controller (AVC). The DCDC converter and the AVC can be housed in a common package to reduce the size, weight, and complexity of the power system while also improving the power system's durability.Type: GrantFiled: March 9, 2018Date of Patent: April 12, 2022Assignee: FARADAY & FUTURE INC.Inventors: John Steven Linehan, Steven E.
