A quick way to wear out EV batteries: V2G power won’t make sense without smarter grids
There was controversy recently when two different research groups came to two different conclusions about the practicality of using the lithium-ion batteries in electric vehicles as a source of power for the utility grid. The idea behind vehicle-to-grid (V2G) proposals is that EVs can send the power in their batteries to low-voltage microgrids or buildings, […]
The fundamentals of supercapacitor balancing
The low voltage available from a single supercapacitor forces most applications to use several supercaps in series. Here are the tricks involved in stringing these components together. Robert Chao | Advanced Linear Devices Inc. The average supercapacitor has a maximum charging voltage of between 2.5 and 2.7 V. For many applications a voltage this low […]
