BEIJING, Sept. 12 (Xinhua) — The following is a summary of published science and technology news of China.

POWER BATTERIES

China’s installed capacity of power batteries registered rapid growth in August amid the boom of the country’s new energy vehicle (NEV) market, industry data showed.

Last month, the installed capacity of power batteries for NEVs rose by 121 percent, year on year, to a total of 27.8 gigawatt-hours (GWh), according to the China Association of Automobile Manufacturers.

E-COMMERCE LOGISTICS

China’s e-commerce logistics index saw a decline in August due to sporadic resurgences of COVID-19 cases, industry data showed.

The index came in at 104.2 points last month, down 2.2 points from the previous month, according to a survey jointly conducted by the China Federation of Logistics and Purchasing and e-commerce giant JD.com.

The survey attributed the contraction of e-commerce logistics businesses to disruptions caused by COVID-19 in market demand and supply in August.

INTELLIGENT UAV

With a fuselage length of fewer than two meters, a flight time of four hours, and a maximum speed of 110 km per hour, the E25 unmanned aerial vehicle (UAV) played a vital role in extinguishing a forest fire in southwest China’s Chongqing Municipality in August.

Intelligent UAVs are now being used in many scenarios, especially in complex environments, which can effectively reduce labor costs and improve work efficiency, said Zheng Wei, general manager of Chongqing Efly Technology Co., Ltd, E25’s manufacturer.

The UAVs were used for searching for potential ignition points and conducting fire detection and residual fire monitoring during the forest fire.
