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 at the Guangdong Quality Inspection Institute, said in an interview with the Daily Economic News yesterday (September 21) that at the seminar, about 20 companies discussed the standard issues of lithium battery for drones, including high rate discharge performance. , high temperature storage, cycle life and safety performance, the local standard is expected to be introduced in June 2016.
He Longping believes that this standard will become the most important basis for UAVs to select suppliers, and is a threshold for UAV battery industry access.
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 at 60 ° C for 30 days and the discharge time is not lower than 1.5h, the battery should not be bulged, not leaking, no fire, no explosion.
Li Zhenqiang, head of the High-tech Lithium-Ion Industry Research Institute, said that there are only one or two domestic companies that can meet this requirement. It is understood that there are currently about 30 companies with UAV production capacity, mainly in Guangdong Province.
The first local standard is expected to be released next year
After the singer Wang Feng proposed to marry the drone market, the relevant industry chain ushered in an outbreak period. However, due to the drone battery problem, the safety accidents that caused the fire were frequent, which gradually attracted the attention of the industry.
On September 16, Guangdong Quality Inspection Institute brought together about 20 companies to hold the first local standard seminar for domestic lithium battery for drones. 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 in, but the battery has become the chief culprit of many UAV explosions and fires. In this context, the Guangdong Quality Inspection Institute put forward the standard, the original intention is to regulate the development of the industry, protect consumer safety, avoid vicious competition, and improve the competitiveness of Chinese enterprises entering the international market. The standard is expected to be released in June 2016.
Li Zhenqiang said that 80% of the UAV and UAV lithium battery companies are concentrated in Guangdong Province. The release of this 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 for drone lithium battery is about 6 billion yuan. After the plant protection drone is up, this market will double." He Longping said that the future development of lithium battery for drones depends on the drone market.
According to him, the use environment of the lithium battery of the drone is special and the price is high. Take the battery of Dajiang Science and Technology "Elves 3" as an example, the market price is as high as 840 yuan / block, and generally there is a lot of unmanned opportunities. Block lithium battery, "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 lithium battery and power management system. In addition, it is understood that Desai battery (000049, SZ) is also actively entering the drone lithium battery industry.
High temperature energy storage is difficult to live in most of the battery factory
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 emerging." 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 at 60 ° C 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 sparked a heated discussion at the seminar. "Daily Economic News" reporter noted that this single rule has blocked most of the battery factory in the drone battery industry.
He Longping also revealed that “the battery manufacturer feels that the difficulty is too great. Dajiang’s technology requirements are indeed much more stringent, but as a result, the DJI drones are very recognized in the domestic and overseas markets.â€
Li Zhenqiang also told reporters that the performance of domestic lithium battery products for drones is quite different. According to the above criteria, only one or two companies in China can meet the requirements.
He believes that the regulations proposed by Dajiang Science and Technology indicate that Dajiang has locked in several suppliers, but it is not excluded that Dajiang uses different suppliers to supply different products. “A well-known drone battery company in the industry had poor battery storage performance due to poor battery storage performance and was notorious in the industry.†He Longping told reporters.
Li Zhenqiang said that the stability of traditional lithium batteries in high-temperature environment, discharge and other performance is inherently poor, it is difficult to meet the requirements of high-temperature storage of drones.
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."
