On August 2, at the rice planting base of Dongxin Farm in Lianyungang, five plant protection drones were spraying pesticides for the integrated control of rice sheath blight, rice planthopper and other pests and diseases. The State Grid was charging these drones. The mobile energy storage shelter jointly developed by Lianyungang Power Supply Company and China Electric Power Research Institute can simultaneously meet the outdoor charging needs of four agricultural electric machinery such as plant protection drones.
"When our plant protection drone is fully loaded, it needs to updat the battery for continuous operation for about 15 minutes. In the past, charging with diesel generators was polluting, noisy and expensive. Now we use mobile energy storage methods. Charging the cabin is not only convenient and fast, but also energy-saving and environmentally friendly.” said Xu Shidong, director of the Agriculture and Animal Husbandry Center of Lianyungang Dongxin Farm.
Plant protection drones have "charging treasure"
Dongxin Farm is the largest state-owned farm in East China, with an area of ​​200,000 mu of arable land. It mainly grows rice, wheat, soybeans and other crops. Daily spraying and fertilization mainly rely on 120 plant protection drones for operation. Demand is high. According to estimates, using diesel generators to charge uavs costs 1.6 yuan/kWh to generate electricity, about 0.3 yuan per mu of farmland on average, and spraying pesticides and fertilizers about 20 times a year requires more than 1.2 million yuan in fuel costs. After using the mobile energy storage cabin, the charging cost can be reduced to 0.5 yuan/kWh, which can save 825,000 yuan per year and reduce carbon emissions by 384 tons.
"Our mobile energy storage shelter is specially designed for agricultural application scenarios, featuring high efficiency and stability, and can be used in harsh outdoor environments. Emergency lighting, power protection for important events and other scenarios, to achieve 'one machine with multiple uses'". Zhu Guangqing, deputy director of the Marketing Office of the State Grid Lianyungang Power Supply Company, said that the mobile energy storage cabin consists of 56 lithium iron phosphate battery packs, with a total capacity of 56.3 kWh, equivalent to the capacity of 2,253 smartphone batteries, using 32-amp AC The slow charging and 30 kW DC fast charging interface can meet the charging needs of different scenarios. A 2900 mAh plant protection drone battery can be fully charged in only 10 minutes at the fastest.
Plant protection drones are spraying pesticides
At present, with the continuous development of intelligent modern agriculture, the popularity of high-tech electric agricultural appliances such as plant protection drones is accelerating in the fields of agricultural irrigation, spraying, and fertilization. It is understood that as of 2021, Jiangsu Province has a total of 14,000 plant protection drones. This year, the province will continue to implement the pilot application of plant protection drones piloting aircraft subsidies, with an annual pilot subsidy fund of 50 million yuan. The comprehensive mechanization rate of crop cultivation and harvesting in the province, including the application of plant protection drones, has reached 83%. The main team of professional agricultural machinery services has basically been formed, and new models of agricultural machinery service entities such as "full mechanization + comprehensive farming" are gradually being launched.target drone
