It is worth noting that the drone industry leader Shenzhen Dajiang Innovation Technology Co., Ltd. (hereinafter referred to as Dajiang Science and Technology) proposed high-temperature storage items at the seminar, requiring the battery pack to be stored in a 60 ° C environment for 30 days and the discharge time is not low. At 1.5h, the battery should not be bulged, leaked, fired, or exploded. According to industry insiders, there are only one or two domestic companies that can meet this requirement. If this is proposed by Dajiang Science and Technology, it indicates that Dajiang Technology has locked in one or two suppliers, but it does not rule out that it will adopt other suppliers according to different product layouts. It is understood that there are currently about 30 companies with UAV production capacity, mainly in Guangdong Province. The first local standard is scheduled to be released in the next year. After Wang Feng’s marriage proposal ignited the drone market, the UAV industrial chain ushered in an outbreak, and the safety accidents that drones crashed due to battery problems and fires frequently caused the industry’s high attention. On September 16, the Guangdong Quality Inspection Institute brought together about 20 drones and lithium battery companies to hold the first local standard seminar for domestic lithium battery batteries. It is understood that the Guangdong Quality Inspection Institute is also the secretariat of the Guangdong Power Battery Standardization Technical Committee. The "Daily Economic News" reporter learned that the focus of the seminar discussion focused on the electrical performance requirements of the lithium battery of the drone, the range of high-temperature storage and environmental adaptability. He Longping told reporters that in the past two years, the drone market has developed rapidly, and many UAV companies and related accessory companies have begun to flood. The battery has become the chief culprit in the explosion and fire of many drones. In this context, the Guangdong Quality Inspection Institute put forward the standard. The original intention was that before the drone lithium battery industry had not broken out, the industry development was regulated, consumer safety was guaranteed, vicious competition was avoided, and the competitiveness of Chinese enterprises entering the international market was improved. The standard is expected to be released in June 2016. According to industry insiders, 80% of the UAV and UAV lithium battery companies are concentrated in Guangdong Province. The release of the local standard will help promote the development of the domestic drone battery industry. Regarding whether the standard is a mandatory standard, He Longping said that the standard will become the most important basis for UAVs to select suppliers. The threshold for UAV battery industry access is also the relevant quality inspection unit. Provide evidence for product implementation supervision. "This year, the domestic market of drone lithium battery is about 6 billion yuan. After the plant protection drone is up, this market will double again." He Longping said that the future development of UAV lithium batteries depends on the drone market. According to him, the lithium battery used in drones has a special environment and high price. Taking the battery of Dajiang Science and Technology "Elves 3" as an example, the market price is as high as 840 yuan / block. And generally one unmanned opportunity is equipped with multiple UAV batteries. “This market is very imaginative.†In May of this year, Xinwangda (300207.SZ) confirmed on the investor interaction platform that it has cooperated with Dajiang Science and Technology to supply its drone battery and power management system. In addition, it is understood that Desai Battery (000049.SZ) is also actively following the drone lithium battery industry. High temperature storage is difficult to live in most battery factories It is understood that there are about 30 domestic enterprises with lithium battery production capacity of drones. "Not only the UAV market in China, the United States and Europe is also on the rise." He Longping said. According to relevant participants, DJI Science and Technology combined with the use of different regions of the world, proposed a high temperature storage regulations at the seminar. "In terms of high-temperature storage conditions, after the battery pack is fully charged, the battery pack is stored in a 60 ° C environment for 30 days, and the battery (group) is removed from the storage environment. After the battery temperature drops to room temperature, the battery is rated at room temperature 0.5C. Capacity test, discharge time is not less than 1.5h, the battery should not be bulged, no leakage, no cracking, no fire, no smoke, no explosion." This provision was hotly debated at the seminar. The reporter noted that this single regulation has blocked most of the battery manufacturers in the drone battery industry. “The battery factory feels that the difficulty is too great. The technical requirements of Dajiang are indeed very strict, but it is also because of this, the DUA is very recognized in the domestic and overseas markets.†He Longping also revealed that “a well-known drone in the industry before Battery companies are notorious for their poor battery storage performance and poor drum kits. However, He Longping told reporters that for this high-temperature storage regulation, "we will combine the opinions of the whole industry to determine the specific parameters. After all, it is only the first draft."

UAV lithium battery standard high temperature storage energy is difficult to live in most enterprises
A few days ago, the Guangdong local standard for lithium battery for drones, "Technical Requirements for Lithium Ion Batteries and Battery Packs for Unmanned Aerial Vehicles" was held at the Guangdong Provincial Product Quality Supervision and Inspection Institute (hereinafter referred to as the Guangdong Quality Inspection Institute). He Longping, an engineer of the Guangdong Quality Inspection Institute, said in an interview with the Daily Economic News yesterday (September 21) that at the seminar, the UAV machine was most concerned about the high rate discharge performance of lithium batteries and high temperature storage. , cycle life and safety performance issues. The local standard is expected to be introduced in June 2016. He Longping believes that the standard will become the most important basis for UAVs to select suppliers, and it is a threshold for UAV battery industry access.
