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.

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 »

Texas Instruments introduces integrated battery monitor and protector
