With the development of science and technology, high-risk occupations are gradually being replaced by equipment. Industrial drones focus on solving industry problems and improving efficiency, such as agricultural plant protection, power patrols, safety inspections, forest fire prevention, aerial surveys, police, and firefighting, playing an important role. This also reduces the possibility of accidents in various high-risk work, but after all, batteries are flammable and explosive products. So how should industrial drone batteries be stored and maintained? Below, lithium battery manufacturer Youchuangwei will introduce the maintenance methods for industrial drone batteries.
1. Storage temperature
Currently, lithium polymer batteries are commonly used in industrial drone batteries. The raw material for lithium polymer batteries is lithium metal, and the chemical properties of lithium metal are very active, making the processing, storage, and use of lithium metal highly environmentally demanding.
Lithium polymer batteries have high and low temperature adaptability. It can be used in environments ranging from -20 ° C to 60 ° C, as well as in processing environments ranging from -45 ° C. But this does not mean that their storage temperature is the same. It is best to maintain the storage temperature between 18 ° C and 25 ° C. The maximum value shall not exceed 30 degrees Celsius. The chemical properties of the battery are most stable at this temperature.
If the storage temperature is too high, the electrolyte inside the battery can easily penetrate the separator. If the storage temperature is too low, heating is required when removing and using the battery. Both of these situations can easily lead to increased battery consumption.
2. Dust control
When storing industrial drone batteries, it is necessary to strictly control the dust in the air. There are three reasons. Firstly, covering the exposed plug will affect the maximum effect of battery discharge. Secondly, mixing dust in the air with metal impurities on warehouse shelves can increase the internal resistance of the battery. Thirdly, the long-term impact on the battery's storage capacity increases its self consumption capacity.
3. Storage humidity
Moisture has a significant impact on industrial drone batteries. Not only in all aspects of production, but also in future battery storage, it cannot be ignored. Water vapor in the air may seep into the outer packaging of the battery. The electrolyte in a battery is a substance that is afraid of water. It is also very easy to absorb water and react with it until all electrolyte materials are fixed. In other words, its drinking capacity is endless until it loses its usefulness.
Other metal parts themselves have limited absorption of water, but metal parts are afraid of moisture. Because the presence of water can cause it to rust or corrode. The moisture in the material is the main source of moisture in the battery. The higher the environmental humidity, the easier it is for the battery material to absorb moisture. The battery will undergo irreversible chemical reactions, which will shorten its lifespan.
Firstly, the battery can be protected by controlling the dryness of the warehouse. Secondly, control the moisture content of the battery. When storing and using batteries, warehouse personnel should wear masks and anti-static clothing. This protection is bidirectional, which can protect the battery and protect us from dust. In the bathroom equipped with an automatic hand dryer, wash hands, blow dry and return to the warehouse.
4. Battery placement
According to the requirements for battery placement, it is recommended to maintain a space of 0.5-0.8 meters between the boxes. Firstly, this can prevent batteries from harming each other. Secondly, some flexible packaging batteries are self powered, and weak currents cannot be ignored. Thirdly, in the event of an accident, isolation can also be carried out as soon as possible.
