Battery and charging
The Sinotruk HOWO TX Battery-Swap Tractor 6×4 is offered with 282 – 350 kWh batteries of lithium iron phosphate (LFP) cells from CATL, below 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 battery swapping, where a swap station exchanges the depleted pack for a charged one in about five minutes. Swapping keeps a truck working around the clock and is widespread on Chinese freight corridors, mines and construction sites, where swap stations serve whole fleets.
Power and drive
Its electric drive delivers 240 – 270 kW continuously and 360 – 410 kW at peak (550 hp); its peak power is below the median of 480 kW across the 26 electric semi trucks in our database.
