Phosphorus-doped three-dimensional hierarchical porous carbons (P-3DHPCs) have been synthesized by direct pyrolysis of mixture containing glucose, manganese nitrate and sodium hypophosphite without any hard templates. Glucose and sodium hypophosphite are used as carbon and phosphorus source in the facile template-free strategy, respectively. The P-3DHPCs not only possess favorable hierarchical pore...
Three-dimensional hierarchical porous carbons were synthesized by direct carbonization of glucose and zinc nitrate mixtures. The effects of carbonization temperature on the formation of the microscopic pore structure were studied. When tested in 6 M KOH by three-electrode system, the carbon sample carbonized at 750 °C shows the best electrochemical performance compared to the other samples. High specific...
This work report the synthesis of porous carbon with hierarchical pore structure and uniform nitrogen-sulfur-oxygen doping. The favorable pore structure (micro-, meso-, and macro-pores) is beneficial to ion adsorption and transportation, and the doping heteroatoms can introduce electrochemical active sites which contribute to additional pseudocapacitance. Therefore, the carbon material shows good...
This paper studies the optimal sizing and the experimental verification of a vehicle-used hybrid energy storage system (HESS). To determine the optimized combination that maximizes the traveling distance at an FTP driving pattern, an exhaustive search method was employed. Under constraints of cost, vehicle acceleration, and HESS gross weight, the optimal sizing can be derived. Next, for the purpose...
For verifying the strategy of the vehicle control unit(VCU), a real-time simulation environment needs to be established in advance. It is modified from our in-house simulator for the electric vehicle (EV) based on the hardware in-the-loop(HIL) structure and constrained by several communication devices, e.g. CAN bus, AI/O, DI/O, etc.. A dual energy storage system (DESS) has been modeled in this simulator...
