Electropedia: The World’s Online Electrotechnical Vocabulary
Public consultation on joint ISO standard 80000 that defines quantities and units for space, time, thermodynamics, light, radiation and even the characteristic numbers for each of the foregoing closes October 11th.
“City at night” 1958 | Harald Rudyard Engman
Electropedia is produced by the world’s peak electrotechnical standardization organization that oversees 214 technical committees that provide a neutral and independent platform where agreement can be found on electrotechnical solutions with global relevance and reach. The IEC operates close-coupled with the European Committee for Electrotechnical Standardization (CENELEC)

Campus Electric Transit
University of Michigan | Washtenaw County
Widespread use of electric vehicles (EVs) on large university campuses offers significant possibilities but also presents challenges. Possibilities include reduced carbon emissions, aligning with sustainability goals, as EVs produce zero tailpipe emissions compared to gasoline-powered vehicles. Campuses could deploy electric shuttles, maintenance vehicles, or shared EV fleets, decreasing reliance on fossil fuels. EVs could integrate with campus microgrids, leveraging renewable energy sources like solar panels. They also promote quieter environments, reducing noise pollution in academic settings. Universities could foster innovation by integrating EV infrastructure into research, such as smart grid technology or battery development.
Pros include environmental benefits, lower operating costs (electricity is cheaper than fuel), and enhanced campus branding as eco-friendly. EVs require less maintenance, saving long-term costs. Students and staff benefit from cleaner air and modern transportation options.
Cons include high upfront costs for EVs and charging infrastructure, straining budgets. Limited range and charging times may disrupt campus operations, especially for time-sensitive tasks. Charging station availability could lead to congestion or inequitable access. Battery production raises ethical concerns about resource extraction. Retrofitting existing fleets and managing grid demand pose logistical hurdles.
Balancing these factors requires strategic planning, but EVs could transform campus mobility sustainably.
We have followed standards setting action in this domain since 1993. During todays colloquium at 15:00 UTC we will answer questions about our involvement, guided by our Safer-Simpler-Lower Cost – Longer Lasting advocacy in all relevant standards.

Wireless EV Charging
Wireless electric vehicle charging on streets uses electromagnetic induction to transfer power without physical connectors. A primary coil, embedded in the road surface, generates an alternating magnetic field when energized by an external power source. A secondary coil, installed on the EV’s underside, captures this field, inducing an electric current that charges the vehicle’s battery. Efficient power transfer requires precise alignment between coils, often aided by sensors or magnetic guidance systems.
Operating typically at frequencies of 20–100 kHz, the system ensures safe, non-contact energy transfer with efficiencies up to 90%. Power levels vary from 3.3 kW for slow charging to 22 kW or higher for faster systems. Infrastructure includes power inverters, communication modules for vehicle-grid interaction, and safety mechanisms to prevent electromagnetic interference or hazards. Dynamic charging, where EVs charge while moving, extends this concept using sequential coil activation along roads.
