The cost of batteries for electric vehicles is falling markedly. Industry reports show that sales-weighted battery pack prices in 2019 were an average of USD 156 per kilowatt-hour, down from more than USD 1 100/kWh in 2010. The average battery pack size across electric light-duty vehicles sold (including battery electric vehicles and plug-in hybrid electric vehicles) continues an upwards trend; it is now 44 kWh, up from 37 kWh in 2018, and battery electric cars in most countries are in the 50-70 kWh range. This increase is driven by two trends: battery electric vehicle models with longer ranges are becoming available and are increasingly in demand, and the share of battery electric vehicles relative to plug-in hybrid electric vehicles is rising.
