Coulombic efficiency (CE) is the ratio of the number of electrons transferred out of a battery to the number of electrons transferred back into the battery over a full charge cycle. It’s sometimes called Faradaic efficiency or current efficiency. The … [Read more...]
What is well-to-wheel efficiency in an EV?
Well-to-wheel (WTW, or W2W) efficiency is a way to measure the total efficiency of operating a vehicle, beginning with obtaining the fuel at the primary source, the ‘well,’ through the entire delivery chain and in the drivetrain of the vehicle, all … [Read more...]
How is the energy consumption and range of EVs measured?
Today’s testing standards for measuring the energy consumption and range of electric vehicles (EVs) are based on techniques initially developed for use with internal combustion engine (ICE) vehicles. How it works: the vehicle is run on a … [Read more...]
