The term DC link has traditionally referred to the junction between two power conversion stages where an energy storage element (almost always a capacitor) acts as a buffer for each. A classic example is the capacitor placed between the rectifier and the voltage source inverter in a mains-supplied variable frequency drive (see Fig. 1). This… Read more »

New analytical model from Rice University helps fine-tune battery performance
Rice University engineers have devised a simpler and more efficient way to predict battery performance, which they claim is 100,000 times faster than current modeling techniques. The analytical model developed by materials scientist Ming Tang and graduate student Fan Wang of Rice University’s Brown School of Engineering doesn’t require complex numerical simulation to guide the… Read more »
Accelerated electrode drying could reduce battery production cost
A new EPIC project coordinated by Karlsruhe Institute of Technology (KIT) is aimed at accelerating the drying of electrodes for lithium-ion batteries, increasing the energy efficiency of this process and reducing production cost. KIT says innovative electrode drying management can reduce the cost of battery production and improve environmental performance. The quality of Li-ion battery… Read more »

New Li-ion superconductor could lead to safer batteries
Researchers from the Korea Institute of Science and Technology (KIST) claim to have developed a sulfide-based superionic conductor—a material with high ion transport properties corresponding to ion conductivity of 10 to 100 mS/cm at room temperature—that can be used as a high-performance solid electrolyte in all-solid-state batteries. All-solid-state battery technology could solve the safety issues… Read more »
DAF’s CF Electric refuse truck begins field tests in the Netherlands
As part of a field test of four comparable vehicles, the first DAF CF Electric 6×2 refuse collection truck has begun operations with Dutch public waste disposal firm ROVA. The vehicle will serve the Dutch city of Zwolle. Since the end of 2018, DAF CF Electric 4×2 tractors have been in operation for inner-city distribution… Read more »
A look at BMS validation testing
The battery pack is not only one of the most expensive components in an EV—it’s also incredibly complex, in some cases comprising thousands of individual cells. The tasks of preserving a battery’s efficiency, lifespan, thermal stability and safety rest upon the battery management system (BMS), an embedded controller that regulates the flow and distribution of… Read more »
