Ultracapacitors supercharge stop/start systems
Electrification is quietly sneaking into “conventional” vehicles, as more models incorporate stop/start technology. Navigant Research predicts that 54% of new vehicles worldwide will have stop/start capability by 2022. Different automakers are applying stop/start in very different ways. For energy storage, a stop/start system may use Li-ion batteries, advanced-glass-mat (AGM) lead-acid batteries, ultracapacitors (UCs), or some… Read more »
Automotive segment consumes 10.5% of global advanced battery production
Batteries are big business. According to the latest Advanced Battery Tracker from Navigant Research, more than 6 billion advanced battery cells were sold in 2013, representing 40 gigawatts of power capacity and more than $13.4 billion in sales (a modest increase over 2012’s $12.8 billion). The majority of these batteries were manufactured in China. Most… Read more »
New simulation software provides a powerful tool for battery developers
