BYD B series
The BYD B series are a line of battery electric buses produced by Chinese vehicle manufacturer BYD. It is the first bus model powered by BYD's Lithium Iron Phosphate Blade batteries. It is available as a 10-metre single-decker (B10), a 12-metre single-decker (B12) and as a 12-metre double-decker (B12D). History 
The BYD B series was launched on 29 July 2020, superseding the highly popular BYD K series. The bodywork was designed by Wolfgang Egger. According to BYD, the new bus models feature LED water lamps, USB charging ports, newer-generation wheel hub motors which are 6% more energy-efficient, as well as a lightweight aluminum frame reducing the body weight by up to 10%.
