Such is the case with the "Fact of the Week" release, focusing on the total batter capacity increase for plug-in electric vehicles in 2015″

TOTAL BATTERY CAPACITY OF ALL PLUG-IN ELECTRIC VEHICLES SOLD INCREASED FROM 2014 TO 2015

The number of battery packs sold for plug-in electric vehicles (PEV) declined by 3.4% from 2014 to 2015. However, the total battery capacity for all PEVs sold between 2014 and 2015 increased by 22.6%. The rising battery capacities of PEV models have increased battery production even when sales of battery packs are down. Following the introduction of mass market PEVs in 2011, the total battery capacity sold increased nearly tenfold from 0.4 to 3.8 million kW-hrs by 2015.
