“…According The electrochemical models of the VRB are based on the conservation law of mass, species concentration, and energy. Several VRB models have been developed [15][16][17]. These models give insights on membrane investigation, electrode design, electrolyte selection, and flow frame optimization [15,16].…”

This letter presents a design for a novel voltage controller (NVC) which can exhibit three different reactions using the integration of a vanadium redox battery (VRB) with solar energy, and uses only electrochemical potentials with optimal external bias voltage control to carry out hydrogen production and the conversion of carbon dioxide (CO 2 ) into methane and methanol. This NVC is simply constructed by using dynamic switch and control strategies with a time-variant control system. In this design, the interval voltage bias solutions obtained by the proposed NVC exhibit better voltage ranges and good agreement with the practical scenarios, which will bring significant benefits to operation for continuous reduction of CO 2 into value-added clean fuels using the integration of a VRB with solar energy or any other renewable energy resource for future applications.

Abstract:To improve the accuracy of insulation monitoring between the battery pack and chassis of electric vehicles, we established a serial battery pack model composed of first-order resistor-capacitor (RC) circuit battery cells. We then designed a low-voltage, low-frequency insulation monitoring model based on this serial battery pack model. An extended Kalman filter (EKF) was designed for this non-linear system to filter the measured results, thus mitigating the influence of noise. Experimental and simulation results show that the proposed monitoring model and extended Kalman filtering algorithm for insulation resistance monitoring present satisfactory estimation accuracy and robustness.

Abstract-Integrated microfluidic power generation and power delivery promises to be a disruptive packaging technology with the potential to combat dark silicon. It essentially consists of integrated microchannel-based electrochemical "flow cells" in a 2D/3D multiprocessor system-on-chip (MPSoC), that generate electricity to power up the entire or part of the chip, while also simultaneously acting as a high-efficiency microfluidic heat sink. Further development of this technology requires efficient modeling tools that would assess the efficacy of such solutions and help perform early-stage design space exploration. In this paper, we propose a compact mathematical model, called PowerCool, that performs electro-chemical modeling and simulation of integrated microfluidic power generation in MPSoCs. The accuracy of the model has been validated against fine-grained multiphysics simulations of flow cells in the COMSOL software that is unsuitable for EDA because of large simulation times. PowerCool model is demonstrated to be up to 425x times faster than COMSOL simulations while incurring a worst-case error of only 5%. Furthermore, the PowerCool model has been used to study and assess the efficacy of this technology for a test MPSoC.
