Which car firm will dominate the future? Tesla and its BEVs or Toyota with its hybrids? Schalk Cloete looks at the cost reductions coming down the line. He says that the hybrids have many more improvements on the way, whereas in terms of performance and efficiency the BEVs are already reaching their peak. Though further and considerable progress in battery technology is coming, it will benefit both. For city driving both will rely on battery … [Read more...]
Machine learning cuts new EV battery design testing times by months, years
Normally, battery prototype testing can take months and years to find the optimal design for fast-charging and battery life. Now scientists from Stanford, MIT and the Toyota Research Institute have developed a machine learning programme that can cut battery testing times by 98%. They’ve applied it to EV batteries. The faster a new and improved design is proven and taken to market the more rapid the uptake of EVs we’ll have. Matthew Vollrath at … [Read more...]
Will Toyota’s new battery design solve the looming shortage of vital metals for renewables?
We all know the important part played by lithium in battery manufacture. But there is a longer list of metals - including copper, cobalt and neodymium – that must ramp up supply for the continued rapid growth of EVs, solar, wind and other renewables technologies. EVs alone will increase the consumption of copper nine-fold by 2027. Cobalt prices already doubled in 2017. Neodymium use will rise by 700% in the next few decades to satisfy our need … [Read more...]
