Electric bus sales worldwide are growing at a rate of 20 per cent a year and could prove a "game changer" for the fast-expanding global battery market, according to a new report from research firm According to a recent report from IDTechEx , the electric bus market is growing at 20 % per year in unit price , which is “ a game changer ” for the battery market , as these vehicles require large - sized batteries ranging from 74 kWh ( for a fast charging e - bus ) to over 300 kWh ( for slow charging e - buses ) . As a result , the research house forecasts that the e - bus battery market will dominate the consumer electronics market by 2020 and reach $ 30bn by 2026 . " We expect that this sector will alter the entire value chain for battery production from material suppliers , battery manufacturers through to original equipment manufacturers , " said IDTechEx .
