Unmanned aerial vehicle power supply Drone Power Supply: How does the drone strike supply power? Built-in high-capacity battery ensures long standby time, and two batteries can be replaced at any time. UAV power supply: how to calculate the voltage of the UAV battery in seconds?
One second is a battery cell, which is 3.7 V, and several seconds refers to the number of batteries in series. Portable devices that require high power in series are typically powered by a battery pack of two or more batteries connected in series. If a high voltage DC-DC converter is used, the size of the conductor and the switch can be made small. Another problem with using battery packs is the possibility that one of the batteries in the battery pack will fail.
It’s like a chain, and the more batteries you have in series, the higher the chance of this happening. As long as there is a problem with one battery, its voltage will drop. In the end, a “disconnected” battery may interrupt the delivery of current. It is not easy to replace the “bad” battery. Precautions for battery series connection (1) DC-DC converters of the same manufacturer, model and batch should be selected to ensure the consistency of various performances among batteries, and single batteries should be selected as far as possible. In the process of use and maintenance, the relevant data of each battery can be easily observed. It is forbidden to use batteries of different manufacturers, different models, different types, different capacities, different performances and different degrees of age in series or in parallel. Batteries with inconsistent performances are not easy to maintain and will affect the life of batteries. (2) It is better to connect the batteries in series. Appropriate DC-DC converters should be selected and then connected in series to form a battery pack. In general, only batteries with a capacity of more than.h can be connected in parallel. (3) Installation position The battery should be placed in a ventilated, dry place away from heat sources and in a place where sparks are not easy to occur. The batteries should not be placed too densely. At least a distance should be kept between single batteries.
