The unmanned aerial vehicle intelligent charger comprises an AC / DC unit, a DC / DC unit, a microprocessor, a balance charging module, a battery module, a battery module voltage detection unit, a USB power supply unit, a USB output charging jack, a voltage / current sensor, a keyboard, a display unit, a heat dissipation fan driving unit, a heat dissipation fan, a wifi unit, a USB interface, an isolated type communication interface chip and a thermistor sensor. Since an active balancing technology is employed, the charging efficiency and the charging speed are improved, and the service life and the safety of a lithium battery are effectively protected; the microprocessor is provided with the USB interface and supports program updating of hardware with a USB port or an SD card; the microprocessor is connected with the WIFI unit so as to realize such functions as real-time monitoring of a client through an mobile phone APP and the like; the microprocessor unit automatically adjusts and controls the size of DC / DC output signals according to the DC / DC output signals detected by the voltage and current sensor; by use of the isolated type communication interface chip, EMI (electromagnetic interference) is reduced, and the wiring length and the signal-to-noise performance of a system are greatly improved; and by use of the battery module voltage detection unit, each independent battery in the battery module can be monitored, and each battery is effectively controlled.

Description

technical field [0001] The invention relates to the technical field of charging for unmanned aerial vehicles, and more specifically, relates to an intelligent charging machine for unmanned aerial vehicles. Background technique [0002] With the development of science and technology, drone technology is becoming more and more mature, and the control of drones is becoming more and more stable, and related applications in military, disaster relief, and civilian applications have greatly developed. However, a major bottleneck of this technology lies in the low battery life of drones. UAVs basically rely on batteries for power supply. Batteries are one of the most critical systems for drones to fly. Batteries are also widely used in unmanned vehicles. The aircraft starts the engine and the auxiliary power unit, and also provides supporting power for the necessary avionics control equipment, and provides uninterrupted power supply for the protection of navigation equipment and fli...

Problems solved by technology

[0004] The existing equalization technology is mainly divided into energy transfer balance between batteries and external energy input balance. Energy balance between batteries is to charge the energy of high-power batteries to low-power batteries. Now many special-purpose chips or single-chip solutions use external balance. This method is realized through controllable energy consumption. In this method, an energy-consuming element is generally used to consume energy, thereby waiting for other battery cells to be fully charged or reducing the voltage of some battery cells. This scheme The disadvantage is that the energy consumption and heat generation are too large
