Tesla Model S battery pack data shows very little capacity loss over high mileage

‘Lithium’ battery capacity degradation is one of the main concerns of electric vehicle buyers and potential buyers. Since the resurgence of electric cars is relatively recent, meaningful long-term data on large battery packs is fairly rare. Only Tesla has battery packs with a capacity higher than 30 kWh on the road in any significant number and they only have been in operation for a few years (Roadster aside). But a few Tesla owners have accumulated impressive mileage on their vehicles and the data provides an interesting... [Lire la suite]

Better Battery-Control Software Could Double Charging Speed: Research

2014-chevrolet-spark-ev-prototype-sausalito-ca-nov-2012_100409382_l New battery charge estimation algorithms developed by engineers at the University of California (UC), San Diego, are on the verge of vastly improve the capabilities of current lithium-ion batteries. The changes center around improving charging times, potentially allowing for batteries that charge twice as fast as those currently available.The new algorithms make the process of monitoring battery packs much more sophisticated, not only allowing the...
