Publication number: 20230006266Abstract: Systems and methods for storing energy for use by an electric vehicle are disclosed. Systems can include an electric vehicle battery pack including a rack configured to couple a plurality of independently removable battery strings to the vehicle, the battery strings configured to be selectively coupled in parallel to a vehicle power bus. The battery strings may include a housing, a plurality of electrochemical cells disposed within the housing, a circuit for electrically connecting the electrochemical cells, a positive high-voltage connector, a negative high-voltage connector, a switch within the housing, and a string control unit configured to control the switch. Each battery string can include a coolant inlet and a coolant outlet configured to couple with and sealingly uncouple from an external coolant supply conduit and an external coolant return conduit, and an auxiliary connector configured to couple with an external communications system and/or an external low-voltage power supply.Type: ApplicationFiled: February 22, 2022Publication date: January 5, 2023Inventors: Douglas D. Chidester, Nicholas John Sampson

Patent number: 11539087Abstract: The present disclosure is directed to energy storage systems for vehicles. In some aspects, the energy storage system may be used to power an electric automobile. The energy storage system may include a plurality of individual battery cells. The cells may be cylindrical and have a positive and negative terminal on the same side. The cells may be physically and/or electrically organized into bricks. The bricks may be physically and/or electrically organized into modules. The modules may be physically and/or electrically organized into strings. The strings may be physically and/or electrically organized into a pack. In some embodiments, packs, strings, modules and/or bricks may include flexible circuitry and/or may be liquid cooled.Type: GrantFiled: December 29, 2017Date of Patent: December 27, 2022Assignee: Faraday & Future Inc.Inventors: Douglas D. Chidester, Nicholas John Sampson

Patent number: 11381472Abstract: Methods, systems, computer-readable media, and apparatuses are presented for computer-assisted visualization of network devices. One example involves receiving a plurality of standardized network description files describing a plurality of vehicular communication networks connecting a plurality of electronic control units (ECU) for a vehicle. Each of the plurality of standardized network description files may describe a vehicular communication network in the plurality of vehicular communication networks. Each vehicular communication network may comprise a subset of the plurality of ECUs and one or more network communications paths interconnecting the subset of ECUs. The example can further involve automatically generating, based on the standardized network description files, a visual topology representation of the plurality of vehicular communication networks connecting to the plurality of ECUs.Type: GrantFiled: September 29, 2017Date of Patent: July 5, 2022Assignee: Faraday & Future Inc.Inventors: Abhijit Bansal, Douglas D. Chidester, Shan Deng, Jana Mahen Fernando, Matthew K. Lubbers

Patent number: 10259337Abstract: An adaptive multi-string battery for an electric vehicle is disclosed herein. The battery strings can adaptively be connected to the power bus bars based on the output voltage to be discharged with load. During operation of the vehicle, the voltage, current, and estimate charge can be constantly monitored to change the connected status of the battery strings to the power buses to allow connecting or disconnecting of the battery strings adaptively.Type: GrantFiled: October 28, 2016Date of Patent: April 16, 2019Assignee: FARADAY & FUTURE INC.Inventors: John Alser, Douglas D.

Publication number: 20180062988Abstract: A vehicle can use controlled area network (CAN) buses for communications within a subsystem but connect different subsystems using Ethernet connections. For example, a network interface (NIC) of a subsystem can receive a CAN message from a CAN bus and incorporate the CAN message into a user diagram protocol (UDP) message which can be then packaged into an Ethernet packet. The UDP message may include a table of contents (TOC). The TOC may include the message ID and the length of the CAN message. Once a NIC receives the message, the receiving NIC can extract the UDP message from the Ethernet packet, parse through the TOC to identify a CAN message relevant to the control units of the receiving NIC's subsystem, extract the relevant CAN message based on the TOC, and put the CAN message onto CAN buses to be sent to destination CAN devices.Type: ApplicationFiled: August 31, 2016Publication date: March 1, 2018Inventors: Mayank Sikaria, Douglas D.
