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 »

Rice researchers find inserting detours within a battery cathode improves charge/discharge rate
We have all heard the comforting bromide about our imperfections being our greatest strengths. Rice University researchers have recently proven this platitude in the context of battery charging cycles with the discovery that defects purposely inserted into the crystalline lattice of a lithium iron phosphate cathode actually cause the battery to work more, not less,… Read more »

Battery pack prices continue plummeting towards price parity with ICE vehicles
If you drove an EV back in 2010, it’s likely that you paid an average of about $1,100 per kilowatt-hour for your battery pack. By the end of 2019 this figure had fallen a full 87%, to $156 per kWh. According to BloombergNEF’s 2019 Battery Price Survey, the average price by 2023 will be approximately… Read more »
Wallbox’s bidirectional DC home charger turns heads at CES
Bidirectional charging encompasses several applications that can be collectively referred to as V2x (vehicle-to-grid, vehicle-to-home, maybe someday vehicle-to-brain). It’s expected to play an important role in tomorrow’s electrified, connected transportation ecosystem, but to date it exists only in pilots, most of them involving commercial fleets. So the new Quasar bidirectional EV charger from Barcelona-based Wallbox,… Read more »
