How to solve the problem of short life of lithium battery for drones in winter?

How to solve the problem of the short life of the lithium battery of drones in winter? With the increasing scale of drones, some complex drones have appeared on the market, but these drones have an obvious problem with limited endurance. . Battery problems have caused voltage drops, insufficient flight power, and even more serious accidents. In addition to the cold winter temperatures, this is also a very severe test of the function of lithium batteries. Insufficient lithium battery life in winter is even more of a problem. On low-current devices, such as laptops and mobile phones, it is much easier to calculate battery life. But for UAVs, electric vehicles and other systems with large operating currents, large current changes, and chaotic operating conditions, the dynamic calculation of battery life requirements becomes much more complicated. If the battery is left outdoors for a long time, its discharge function will be greatly reduced. If you go to fly while flying at room temperature, problems will definitely occur. What we have to do at this time is to increase the alarm voltage, and then insulate the battery. Before removing the battery, the battery should be placed in a warm environment, such as a house, car, insulated box, etc. Take off quickly to install batteries and perform flight missions. When flying at low temperatures, try to shorten the flight time to half of the normal temperature to ensure flight safety. Charging and energy saving issues have led to the emergence of smart batteries. Now lithium batteries are all the rage. As we all know, there are special requirements for charging lithium batteries. At present, many lithium battery packs use multiple batteries in series and parallel. Due to individual differences in batteries, it is impossible to achieve a 100% balance between charging and discharging. Therefore, a complete set of charging processing circuit is particularly necessary. And this is the second function that a smart lithium battery must have for charging and discharging a perfect lithium battery pack. To further simplify the lithium battery of aspiring drones, take out the modules that do not need to be made repeatedly in the smart battery, and put them into the hovering or charger, such as the discharge processing module and the charging processing module. Not only can the processing cost be reduced without changing the original function, but also the processing capacity can be increased. This is also of great significance to environmental protection, because it does not process circuits that cannot be copied (future electronic waste). The maintenance of the forward flight safety battery is very important. Make sure that the battery is fully charged before flying to ensure that it is in a high-voltage state. Fully preheat the battery to over 25 degrees to reduce the battery resistance. It is recommended to use a battery preheater to preheat the battery. Hover for about 1 minute after takeoff to make the battery make full use of the internal heat, fully preheat itself, and reduce the internal resistance of the battery. The insulation method used for aircraft batteries, such as the sponge pad of the battery, and the thermal insulation grid used for the body with insulated air circulation. Knowing these truths and fulfilling the above suggestions, our winter flight safety factor will be greatly improved, and we can use drones more carefully. The flying principle of unmanned aerial vehicle lithium battery The hovercraft has a larger dead weight and requires more current to maintain its power. Motor hovering continues to stop, such as climbing full throttle, the battery will continue to discharge high current; in plateau areas, where the air is thin and the air pressure is low, the hovering requires a higher motor speed to maintain power, and the battery output current is further increased. The above conditions, coupled with the low temperature in winter, make the voltage drop of the battery further increase; in severe cases, it may even cause the battery to shut down and cause the hovering power supply to fail and collapse due to lack of voltage. The lower the battery temperature, the lower the battery voltage after takeoff. After the battery temperature rises, the voltage slowly returns to normal. If a low-power takeoff occurs, the battery voltage is low at the beginning, and as the battery's body temperature is low, the voltage will quickly drop, which greatly increases the risk of insufficient voltage. So we always focus on our best. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
