BYD introducing battery-electric Type D school bus BYD is introducing a battery-electric Type D school bus. With length options of 35, 38, and 40 feet, BYD’s Type D battery-electric school bus can seat up to 84 and can be equipped with an ADA liftgate. The bus has a range of up to 155 miles on a single charge. The school buses can be charged overnight when energy demand is low, and electricity can be fed back into the classroom during school hours when the bus is parked keeping classrooms well-lit and students and teachers plugged-in. BYD made safety the top priority in its school bus design, including such features as electronic stability control to aid handling, a collision avoidance system, and a 360-degree monitoring system to detect pedestrians and cyclists when the bus is operating at slow speeds.
