August 18, 2016. A grand ceremony is held at the Beijing Convention Center to celebrate the partnership between BYD Company Ltd. and Beijing Environmental Sanitation Engineering Group Ltd. BYD also launches the world’s first pure electric sanitation truck product line with 26 models . 

The Beijing Environmental Sanitation Engineering Group plans to replace 45% of its current diesel fleet for pure electric vehicles by the end of 2016, and replace the whole fleet with electric truck in 2017. 

The payload capacity of the 26 models of the electric trucks series is covering 1 to 32 tons, using as sweeping,compressing and transporting waste etc. The remarkable characters of the trucks are low noise, zero emission, efficiency, long driving ranges, and life-time batteries.   
Additionally to the BYD cutting-edge Iron-Phosphate Battery, the lineup is equipped with several other BYD core technologies. For example, the electric integrated axle assembly technology, which smartly combines the driving motor with the automatic gearbox and drive axle, largely improving transmission efficiency. At the same time, the integrated technology saves extra room for more batteries.  

Another important technology is the use of the independent electric motor to control the fan, and water and fuel pumps. Additionally, an innovative design completely integrates the control systems for both the vehicle’s superstructure and chassis. Another technology is the CAN (Controller Area Network) system, which further improves the vehicle’s reliability. The vehicle body is made of lightweight aluminum alloy which decreases the weight and extends both driving range and life span. The truck is equipped with cameras that grant a 360° view, so that the driver can monitor the whole operational process. The trucks are installed GPS, which renders the vehicle traceable in case of emergency. Furthermore, with Vehicle to Vehicle (V2V) feature, the trucks can be used as a charging unit to serve other trucks.
