Toyota to source recycled EV battery components from Redwood Materials
Redwood Materials, the battery recycling company founded by Tesla co-founder JB Straubel, is focused on two of the most critical battery components: cathode active materials (CAM) and anode copper foil. Together, these two components account for the majority of the cost of a battery cell, the company explains, and at the moment, they are produced… Read more »
How to improve EV traction motor efficiency
A look at improving motor efficiency in two main categories: electrical and mechanical. Regular readers of Charged don’t need to be told that the typical EV drivetrain is way more efficient from battery to wheels than its ICE-based equivalent, but it is perhaps less well-known that the approximate drivetrain efficiency ranges from 75-90% for the… Read more »
Packaging second-life EV batteries into a plug-and-play energy storage system
Q&A with Smartville CEO and co-founder Antoni Tong What do EV batteries have in common with athletes and politicians? Once they age out (or get voted out) of their positions, they have the opportunity to have a lucrative (and in the case of batteries, useful) second career. Repurposing depleted EV batteries for stationary storage applications… Read more »
