It has been carrying out life-cycle management of green products through the three major procedures of green infrastructure construction, low-carbon technology innovations in products and solutions as well as product packaging and transport.


In terms of green infrastructure, ZTE takes its self-developed chips as the source, and carries out green infrastructure deployment of products and solutions in the three major fields of green site, green data center and low carbon energy for the company's energy consuming products.


Green site: It has gradually evolved from macro stack dominated by conventional independent machine room into cabinet mode. Integration level will be further increased in the future by advancing cabinet mode to derrick mode to significantly reduce carbon emission.


Green data center: Green energy-saving technologies have been fully integrated to increase energy utilization rate from the three major perspectives of flexible energy use, thorough use of cold resources and smart management, resulting PUE of no greater than 1.2 in some regions. The implementation of prefabrication idea shortened the construction cycle by 40%; on-demand expansion reduced initial investment by 30%.


Low carbon energy: ZTE's intelligent PV system, which supplies green power to sites, machine rooms and data centers, has realized smooth lamination in all scenarios; mixed use, peak load shifting and other innovative functions of intelligent lithium battery along with shunting control, remote management and other functions of intelligent power supply have realized targeted and intelligent power supply, which further increased power usage efficiency.


As for low-carbon technology innovations in products and solutions, in face of the huge challenges from energy consumption of board card and complete machine manufacturing for RAN, 4G and 5G base stations, ZTE has replaced manual energy conservation by remote automated approaches, and deployed base station energy saving functions. Since deployment of energy saving approaches in this year, it has cumulatively saved more than 1.5 million KWh of electricity, which's equivalent to saving of 468 tons of coal and planting of 133,712 trees. In respect of optimization of product testing procedures, ZTE has added DOAS based on ambient air-cooling practice of the high temperature area. The system takes advantage of difference between indoor and outdoor temperature to replace air-conditioning refrigeration mode in transition seasons, and dissipates heat of aging environment inside glass rooms to reduce air conditioning energy consumption.


By targeting on innovations in the whole life cycle of green products, ZTE has successfully carried out green infrastructure deployment of products and solutions in the three major aspects of green site, green data center and low-carbon energy, improved energy consumption of board card and complete machine manufacturing for RAN, 4G and 5G base stations through remote automated approaches, and optimized product packaging, thus successfully realizing cost reduction and efficiency improvement.



PanGood Power: Resolving Development Dilemmas of Bus Industry Through Innovative Bus Capacity Solutions

Accompanied with the dramatic drop in bus ridership in recent years, the entire bus industry is facing development dilemmas. Buses of certain routes had high empty-loaded rate in off-peak hours, while reduction of departure frequency would lead to overlong waiting time and drop in quality of bus service. To this end, "large space and elastic carrying capacity" has become the key breakthrough point for bus-related technological innovations.


PanGood Power has introduced "BMT" carrying capacity solution in the field of new energy bus, i.e., wheel-side drive system with four airbags and independent suspensions. It replaced the conventional radial-flux machine with axial flux motor of small size, light weight and high efficiency, used distributed driving solution and independent suspension structure, and removed rigid driving axle, transmission shaft, main reducer and differential, thus reducing loss of transmission efficiency and impact of bridge on interior layout and space.


Wheel-side driving system with four airbags and independent suspensions


This system has upgraded the conventional bus model to a new generation of low floor city bus with metro like features of easy access, full-flat floor and wide aisle. Firstly, bus carrying capacity has been effectively enhanced. Benefited from the full-flat floor comes with wheel-side driving system, effective standing area of the whole bus increased significantly. For example, maximum passenger capacity of 8m "BMT" reaches 85 persons, which's equivalent to that of 10m conventional bus model, and that of 10m "BMT" is equivalent to that of 12m conventional bus model.


10.7m "BMT" 12m conventional bus
Maximum passenger capacity of 96 persons Maximum passenger capacity of 98 persons

Structure comparison between new BMT and conventional bus models


Secondly, PanGood's wheel-side drive system with four airbags and independent suspensions endows the "BMT" with a body structure entirely different from that of conventional bus, creating essentially safe use environment for passengers: the one-step boarding feature of the bus can facilitate easy access of senior citizens, children, the disabled and other vulnerable groups, making bus use more convenient and reducing safety hazards.


At last, assembly of the whole system is highly integrated, at the same time of provision of sufficient power output, transmission, transmission shaft and other parts have been removed for simplified mechanical transmission structure which improves the transmission efficiency of the bus and effectively reduces the weight of the bus, increasing the light-weight degree of the complete vehicle. With the same passenger capacity, "BMT" boasts smaller size, lighter weight and lower energy consumption, which effectively reduce operating cost.


By now, "BMT" has been used by King Long, Golden Dragon, Higer, CRRC, Zhongtong and other domestic mainstream OEMs, the number of announced bus models reached more than 60, and over 4,000 such buses have been put into operation in over 40 cities throughout the country, including Shanghai, Fujian, Zhejiang, and Jiangsu. "BMT" plays a significant role in facilitation of energy conservation and emission reduction: on the premise of the same passenger capacity, the use of "BMT" solution can reduce bus weight by around 2-3 tons at production end, and reduce carbon footprint by approximately 4 tons; at operation end, it can reduce carbon emission and operating power consumption by about 120,000 tons and 26%-33% respectively on a yearly basis, and save approximately 15,000 kWh of electricity based on annual operating mileage of 70,000 km, which can realize effective optimization of operating cost while achieving energy conservation and carbon emission reduction. Lower carbon emission of the whole life cycle of vehicle can be realized through reduction of carbon footprint at production end as well as energy conservation and carbon emission reduction at operation end, which has demonstrative long-term effect on the realization of carbon peaking and carbon neutrality goals in the field of urban traffic.
