Patent number: 11818039Abstract: A network appliance can be configured for storing a plurality of flow table entries in a flow table of a match-action pipeline, wherein the match-action pipeline is implemented via a packet processing circuit configured to process a plurality of network traffic flows associated with the plurality of flow table entries. An extended packet processing pipeline of the network appliance can read a flow table entry of the flow table. The extended packet processing pipeline can be implemented via a pipeline circuit. The extended packet processing pipeline can determine that a network traffic flow associated with the flow table entry is expired or terminated. The network appliance can delete the flow table entry from the flow table by processing a traffic flow deletion operation after determining that the network traffic flow is expired or terminated.Type: GrantFiled: August 29, 2022Date of Patent: November 14, 2023Assignee: PENSANDO SYSTEMS INC.Inventors: Sameer Kittur Subrahmanya, Murty Kota, Tuyen Quoc, Harinadh Nagulapalli

Publication number: 20170324122Abstract: Battery packs and SOC monitoring systems are disclosed. The battery pack may include first and second adjacent battery cells and a strain gauge positioned between the first and second battery cells. A stress concentrator may be positioned between the strain gauge and one of the first and second battery cells. The stress concentrator may have a first surface contacting the strain gauge and a second surface opposite the first surface, and an area of first surface may be no greater than an area of the second surface. There may be three or more adjacent battery cells and two or more strain gauges and stress concentrators. A controller may be in communication with the strain gauge(s) and configured to receive strain data therefrom. The strain data may be used to determine a state of charge (SOC) and/or a state of health (SOH) of the battery cells or pack.Type: ApplicationFiled: May 3, 2016Publication date: November 9, 2017Inventors: Eric POIRIER, Tuyen Quoc TRAN, Benjamin A.

Patent number: 9302595Abstract: Systems and methods for controlling a vehicle having a traction battery with a plurality of cell groups each having a plurality of serially connected battery cells include balancing each cell of each cell group with a corresponding autonomous cell balancing circuit, and coupling a single output associated with each cell group to an associated battery monitoring circuit. An integrated driver and switch circuit adapts the voltage from an associated cell group for powering battery monitoring integrated circuits with a voltage range corresponding to a single cell voltage range to facilitate use of an existing battery monitoring integrated circuit design and subsequent input to a microprocessor-based battery controller. Cell balancing is performed at each cell with a battery monitor circuit associated with each group of cells.Type: GrantFiled: January 16, 2013Date of Patent: April 5, 2016Assignee: Ford Global Technologies, LLCInventors: Benjamin A.

Patent number: 9114714Abstract: A portable high voltage charging apparatus (HVCA) can be configured to controllably charge a hybrid electric vehicle (HEV) traction battery using energy provided by a low voltage (LV) lead acid vehicle battery. An HVCA can include a DCDC converter configured to boost a lower input voltage from the LV battery to a higher output voltage provided to the HV battery. The HVCA can be configured with a traction battery interlock, allowing offline charging of the traction battery. In an example embodiment, an HVCA can be configured to communicate with an HV battery control module via a CAN bus. An HVCA can be configured to transfer energy to the HV battery for a predetermined time period, then automatically stop the transfer process. An HVCA can be configured to receive user input to start and/or stop a charging process. An example embodiment can include a supplemental charger to boost LV battery voltage.Type: GrantFiled: September 27, 2012Date of Patent: August 25, 2015Assignee: Ford Global Technologies, LLCInventors: Thanh D.
