What should we do when the UAV Lipo battery could not last long in winter ?

In the market,there are varies of UAV when UAV is increasingly wide range of applications.But also appeared an obvious problem----the limited last time.Battery problem causes the voltage dips,flight underpowered,even more serious case is that sometimes happens aircraft crash etc.Now the cold winter temperatures, for the performance of lithium batteries,it is a very serious test.

UAV battery life shortage problem more often happens in winter

About how to calculate of last time,for some small current devices,it is much simpler,such as the laptop computers, mobile phones and so on.But for UAV,and auto-cars,those kind of things need big current,the the changes of current is big.For complex systems, we need to calculate the dynamic life, then the situation becomes much more complicated.

If the battery is placed outside for a long time, it will greatly reduce the discharge performance, If you still fly in normal temperature status,there will be some problem happens.At this kind of situation,we should do increase alarm voltage.Before take-off,battery should be put in a warm environment, such as the house, the car, incubator and so on.Quick to take off,and perform missions,when the battery is installed.Try to shorten the flight time at a low temperature to room temperature, half of the state, in order to ensure flight safety.

As we all know that there are special requirements when we charge the Lipo battery.Currently a large number of lithium batteries using a multi-core string and form.Since the batteries are individual differences, resulting in the charge and discharge couldnot be 100% balance. Therefore, a complete charge management circuit is particularly necessary.And this is the Smart lithium’s second function - to improve the 2 cell lipo batteries pack charge management, and discharge management.

Ideal UAV intelligent lithium battery, it should be further simplified function,The module does not need to repeat that the shift from manufacturing intelligent battery came out into the aircraft or into the charger,for example: discharge management module, charge management module.Not only can reduce the function without changing the original premise of the production costs, increase productivity, but also has great significance in terms of environmental protection, because those who do not have to repeat the production of the circuit may not necessarily be repeated exist.
