Nuvve activates V2G school bus project in New York
San Diego-based V2G specialist Nuvve has begun operation of a V2G pilot in White Plains, New York. The batteries on five electric school buses, built by Lion Electric, are now providing power to Con Edison’s grid. The charging and discharging takes place at a depot in North White Plains. When plugged in, Nuvve’s V2G platform… Read more »
PREMO offers new inductive couplers for EVs and smart grid applications
PREMO, a manufacturer of inductive components, announces its new MICU family that covers a wide frequency range for power line communications (PLC) in smart grid and EV charging applications. PREMO says the inductive couplers provide these benefits: Non-intrusive (no need to disconnect cables, terminals, etc) Easy to use and install. Clamp, click and connect in… 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 »

TEPCO Ventures invests $2.5 million in V2G provider Fermata Energy
Fermata Energy, a provider of vehicle-to-grid (V2G) technology, has secured a $2.5-million strategic investment from TEPCO Ventures, the investment arm of Tokyo Electric Power. Fermata’s bi-directional chargers enable EV batteries to provide energy storage to the power grid, reducing power loads during peak times and consequently reducing electricity costs. Fermata Energy’s proprietary software system is… Read more »
A closer look at DC-DC converters
As far as we know, all EVs in production by major automakers use a conventional lead-acid battery for the 12 V system (surprising, but true – more on why in a bit) and this battery needs charging, just as it does in an ICE vehicle. While you could hang an alternator off the traction motor… Read more »
Nidec’s Ultra Fast Charger smooths out power demand from the grid
Nidec ASI’s new Ultra Fast Charger (UFC) incorporates 160 kWh of batteries, and functions as a buffer between a charging station and the electrical grid. It can use LV or MV grid connections and, according to Nidec, can supply 320 kW of power to a vehicle, while drawing only 50 kW from the grid. Nidec… Read more »
Bel Power Solutions sees strong growth in industrial electrification and its auxiliary power products
When many people think of electric vehicles, they imagine sleek passenger EVs like the near-quintessential Tesla Model S. However, EVs are by no means restricted to consumer use. As more and more industries move towards electrification, more and more industrial EV solutions will be needed. Bel Power Solutions is a power conversion product provider that… Read more »
Advancing BMS: Linear Technology launches its fourth-generation battery stack monitor
Engineers use battery management systems (BMS) to prevent problems that occur in Li-ion batteries when they are over-charged or over-discharged, including premature capacity loss and thermal events. A BMS ensures precise control and keeps the individual cells balanced, which is critical to extracting the most useful energy from a pack. Fortunately for EV systems designers,… Read more »
