The Shenzhen-based maker of e6 electric cars and K9 electric buses wants to more than double its battery production output this year, from 4 gigawatt hours (GWh) to 10, continuing at that pace for at least three years, according to Reuters. A GWh is a massive unit of electrical energy (equivalent to 1 billion watt hours) used to measure a battery maker’s annual production output.

"We have demonstrated that BYD is capable of adding 6 GWh every year with strong market demand," Matthew Jurjevich, spokesman for BYD's U.S. unit, said in an interview with Reuters published on Friday. At that pace of expansion, BYD could have 34 GWh of capacity by 2020 from its factories the same year Tesla’s $5 billion Nevada factory is scheduled to be churning out 35 GWh.
