What the BYD 8TT is built for
The BYD 8TT is a battery-electric tractor rated for a gross combination weight of 37.2 t (82,000 lb), the weight class of a standard semi-trailer combination (40 – 44 t in Europe and much of Asia, 80,000 lb in the United States): regional distribution, port and terminal shuttles and line-haul between depots.
Its rated weight is below the median of 48 t across the 16 electric semi trucks with a stated gross combination weight in our database.
Battery and charging
The BYD 8TT is offered with 422 – 563 kWh batteries of lithium iron phosphate (LFP) cells, close to the median of 563 kWh across the 25 electric semi trucks in our database. LFP cells hold less energy for their weight than nickel-based ones, but last more charge cycles and tolerate heat and fast charging well, which is why most heavy electric trucks now use them.
It charges by DC fast charging (DC up to 130 kW (422 kWh) or 230 kW (563 kWh)), full charge in 2.5 h (422 kWh) or 3.5 h (563 kWh) on DC.
BYD (RIDE) states 150+ miles with the 422 kWh battery and 200+ miles with the 563 kWh battery (241 – 322 km).
Power and drive
It weighs 11.8 – 13.1 t (26,000 – 28,900 lb) empty.
