Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle batteries, in particular to an intelligent battery for unmanned aerial vehicles. Background technique [0002] The battery management of existing drones can realize functions such as power management, abnormal protection, and host computer communication. However, in actual use, the battery current output is very large, and the interference to the battery management board itself is also great, which often leads to abnormal communication data with the host computer, which leads to misjudgment of the battery status by the UAV, which in turn leads to unmanned The flight abnormality of the drone has seriously affected the flight safety of the drone. In addition, the batteries of existing drones also have the following problems: [0003] 1) The existing drone battery has a self-power supply system inside itself, but it cannot power off the management chip, that is, the management IC (i...

AI Technical Summary

Problems solved by technology

[0003] 1) The existing drone battery has a self-power supply system inside itself, but it cannot power off the management chip, that is, the management IC (integrated circuit). Therefore, when the program is abnormal, the management chip cannot reset itself , although a hardware or software watchdog can be added, but this is more likely to cause an external reset and cause abnormal operation;

[0004] 2) The current of the existing drone battery is very large when it is discharged. Oxide-Semiconductor Field-Effect Transistor (MOSFET for short) will generate a lot of heat. At the same time, when the battery is internally balanced and self-discharged, a large amount of heat will also be generated by a large resistor. Traditional battery casings are airtight and there is no heat dissipation device. , In this way, the heat generated by the battery operation cannot be dissipated in a timely and effective manner, which seriously affects the life of the components in the battery;

[0005] 3) The contact area of ​​the connector through which the large current passes is relatively large, and the plug-in resistance is better. However, the connector for external signal transmission in the existing drone battery often uses a smaller connector, and its contact The area is small, and it often needs to be plugged and unplugged many times during use. After multiple plugs and plugs, it is prone to poor contact, especially when used with a smart charger, this connector wears out faster
