Publication number: 20240109447Abstract: An integrated portable extremely fast charger (XFC) may be installed for heavy-duty off-road vehicles, such as tractors and combine harvesters. The XFC shortens the charging period of plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) by providing >500 kW in a single charger. The proposed XFC integrates a solar farm and local energy storage system (ESS) such that the local grid only needs to provide the power gap between the vehicle battery and the local ESS during charging events, yielding a low-cost XFC installation and higher renewable energy penetration. Two design approaches for the XFC, conductive and wireless, are based on multiphase interleaved dc-dc converter circuit, permitting flexible access to electricity. Smart fault protection mechanism is also proposed to achieve high safety during charging events. The hexagonal prism charger may be integrated into the power electronic devices with a transformer, yielding a high compactness and power density.Type: ApplicationFiled: October 3, 2023Publication date: April 4, 2024Applicant: Drexel UniversityInventors: Fei Lu, Hua Zhang, Yao Wang, Shuyan Zhao, Reza Kheirollahi

Patent number: 11848417Abstract: Ionic liquid N-methyl-N-propyl-pyrrolidinium bis(fluorosulfonyl)imide (Pyr13FSI) was introduced into a hybrid network to obtain a series of gel polymer electrolytes (GPEs). Mechanical and electrochemical properties of the GPEs were tuned through controlling the network structure and ionic liquid contents, and ionic conductivity higher than 1 mS cm?1 at room temperature was achieved. The newly developed GPEs are flame-retardant and show excellent thermal and electrochemical stability as well as ultra-stability with lithium metal anode. Symmetrical lithium cells with the GPEs exhibit a stable cycling over 6800 h at a current density of 0.1 mA cm?2 and stable lithium stripping-plating at 1 mA cm?2, the highest current density reported for ionic liquid-based GPEs. Moreover, Li/LiFePO4 batteries with the obtained GPEs exhibit desirable cycling stability and rate performance over a wide temperature range from 0° C. to 90° C.Type: GrantFiled: May 2, 2021Date of Patent: December 19, 2023Assignee: DREXEL UNIVERSITYInventors: Xiaowei Li, Yongwei Zheng, Christopher Li

Patent number: 11843434Abstract: Low latency beamforming using phased antenna arrays is the key for practical deployment of envisioned millimeter wave (mmWave) Gbps mobile networks. This work aims towards reducing the overhead of the exhaustive sector-level sweep phase of the analog beamforming adopted in the IEEE 802.11ad standard. This system uses a reconfigurable antenna single RF chain in the sub-6 GHz new radio (NR) band to aid codebook-based beam selection in the mmWave band of the NR. The system exploits the congruence between the spatial propagation signatures of signals at both mmWave and sub-6 GHz frequencies to reduce the beam search space.Type: GrantFiled: March 26, 2021Date of Patent: December 12, 2023Assignee: Drexel UniversityInventors: Oday Bshara, Vasil Pano, Md Abu Saleh Tajin, Kapil R.

Publication number: 20230344431Abstract: A field-programmable analog array (FPAA) fabric includes a 6×6 matrix of configurable analog blocks (CABs). The implementation of programmable CABs eliminates the use of fixed analog subcircuits. A unique routing strategy is developed within the CAB units that supports both differential and single-ended mode circuit configurations. The bandwidth limitation due to the routing switches of each individual CAB unit is compensated for through the use of a switch-less routing network between CABs. Algorithms and methodologies facilitate rapid implementation of analog circuits on the FPAA. The proposed FPAA fabric provides high operating speeds as compared to existing FPAA topologies, while providing greater configuration in the CAB units as compared to switch-less FPAA. The FPAA core includes 498 programming switches and 14 global switchless interconnects, while occupying an area of 0.1 mm2 in a 65 nm CMOS process.Type: ApplicationFiled: March 16, 2023Publication date: October 26, 2023Applicant: Drexel UniversityInventors: Ioannis Savidis, Ziyi Chen
