Precautions for UAV operation in high temperature weather in summer
Date:2021-06-03    Hits:2013

UAV is used in all walks of life, can perform all kinds of dangerous tasks without scruple, and has the characteristics of strong concealment, fast response, flexible operation, long-time continuous flight. The cost of development, production and use is much lower than that of manned UAV.


However, there are also some important points for attention in the use of UAV, among which the battery will be affected when working in the high temperature environment in summer, and the battery performance will be seriously reduced, and the internal temperature of the battery will also be continuously increased. The sudden rise of battery temperature due to strong exothermic reaction will lead to thermal runaway, which may cause fire, explosion and other phenomena. Moreover, in the high temperature environment, the battery voltage increases, if the battery is used, it may cause the battery to heat up, and the stored battery will also aggravate the leakage.

Suggestions on high temperature UAV operation in summer

1. Before the UAV takes off, the battery must be fully charged before use to ensure that the battery is in a high voltage state. If the battery is not fully charged, not only the initial voltage of the battery is low, but also the high temperature environment will continue to reduce the battery voltage, which aggravates the risk of insufficient voltage. The battery appearance of UAV should be inspected to confirm whether there is damage, deformation, etc. Check whether the metal sheet of battery interface is damaged or ablated. Check whether the battery charging cable is loose, and whether the battery insertion and removal process is smooth.

2. After the UAV takes off, it operates the stick gently to avoid violent posture. In high temperature environment, the voltage will drop very quickly, so we should pay attention to the power at any time and shorten the flight time. It is recommended to return in advance to avoid low power return.

3. The battery of UAV should not be charged in the high temperature environment and exposed to the hot sun. The battery should not be charged immediately after flying in the high temperature environment, and the charging time should not be too long. The battery will be fully charged when the charger turns green, and it is not allowed to charge for a long time. The battery shall not be used in case of peculiar smell, heating, deformation, discoloration or any other abnormal phenomenon; If the battery is in use or charging, it should be removed from the electrical or charger immediately and stopped using. Do not use batteries in extremely hot environment, such as in the car in direct sunlight or hot weather. Otherwise, the battery will overheat and may ignite, which will affect the performance of the battery and shorten its service life. The battery can only be used under the conditions specified by the cell, otherwise the performance of the battery will be reduced or the service life of the battery will be shortened.


4. When the UAV equipment is not in use, the battery should be removed and stored separately. Do not place the battery close to heat source, inflammable and explosive materials. Avoid long-term storage in high temperature outdoor, otherwise the battery activity will be greatly reduced, and even lead to irreversible decline of lithium battery performance. Keep the storage environment dry. Do not place the battery in places where water leakage, ice and snow melting and humidity may occur. Do not place the battery in the fully discharged state for a long time, so as to avoid the damage of the battery cell caused by the over discharged state, otherwise it will not be able to be used again. For long-term storage, be sure to store at - 10 ° C35 ° Storage in the environment within the scope of C. If it is not used for a long time, it is recommended to recharge and discharge once every 2-3 months to ensure the battery activity.
