[0025] In order to make the purpose, technical scheme and advantage of the present application more clear, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of the present application.

[0026] Figure 1 is a circuit schematic diagram of a kind of anti-overload battery high voltage protection module shown in an exemplary embodiment of the present application, referring to Figure 1 , provide a kind of anti-overload battery high voltage protection module, comprising:

[0027] Resistance wire, triode, mos tube and stabilizing diode;Wherein,

[0028] One end of the resistance wire is connected with the generator output negative pole, and the other end is connected with the battery negative pole;The emitter of the triode is connected with the battery negative pole, and the collector of the triode is connected with the generator output negative pole;The negative terminal of the stabilizing diode is connected with the base of the triode, and the positive terminal of the stabilizing diode is connected with the generator output negative pole;The gate of the mos tube is connected with the collector of the triode, the drain of the mos tube is connected with the battery negative pole, and the source of the mos tube is connected with the generator output negative pole.

[0029] In specific practice, anti-overload battery high voltage protection module will cooperate with the battery voltage regulating system in prior art to act together.When the generator voltage is lower than the battery voltage or higher than the battery voltage but less than a particular value, the battery voltage regulating system acts on the system, and the engine is controlled by PID algorithm, so that the fuel mixed unmanned aerial vehicle battery and generator are in an optimal state, and work stably.

[0030] When the generator voltage is higher than the battery voltage and exceeds a certain value, the anti-overload battery high-voltage protection module enters the working state. The anti-overload battery high-voltage protection module will work together with the battery voltage stabilizing and regulating system. The battery voltage stabilizing and regulating system will quickly pull down the throttle to a certain value to reduce the power generation, and the anti-overload battery high-voltage protection module will shield part of the hardware function of the battery voltage stabilizing and regulating system, so that the battery can quickly absorb excess power as a large capacitor, achieving the effect of voltage stabilization.

When the voltage of the generator is higher than the voltage of the battery but does not exceed a certain value, the power generated by the generator will slowly charge the battery under the protection of the resistance wire, effectively protecting the service life of the battery, in addition to providing power to the unmanned aerial vehicle power system.

[0035] When the voltage exceeds a certain value, the anti-overload battery high-voltage protection module will shield the resistance wire and turn into a fast charging mode to achieve the function of absorbing excess power. The anti-overload battery high-voltage protection module detects the voltage value between the resistance wire, which is initially set to 3.3V. When the voltage between the resistance wire exceeds 3.3V, the mos tube is turned on and the resistance wire is short-circuited.

[0036] As Figure 1 shown, the mos tube adopts N-channel, the source is connected to the ground (the negative electrode of the generator) as the output end, the drain is connected to the negative electrode of the battery as the input end VCC, R4 is the resistance wire, when the voltage between the two ends exceeds 3.3V, the 3.3V voltage stabilizing diode is turned on, the transistor 2N5401 is a PNP type transistor, the emitter and the base generate a conduction current, so that the emitter and the collector of the transistor are turned on, and therefore the gate of the mos tube generates a voltage value, the mos is turned on, the R4 resistor is short-circuited, and the fast charging effect is generated.

[0037] It can be understood that the technical scheme shown in the embodiment can enable the anti-overload battery high-voltage protection module to enter a working state when the voltage of the generator is higher than the voltage of the battery and exceeds a specific value, at this time, the anti-overload battery high-voltage protection module will work together with the battery voltage stabilizing and adjusting system, the battery voltage stabilizing and adjusting system will quickly pull the throttle to a specific value to reduce the power generation, and the anti-overload battery high-voltage protection module will shield part of the hardware function of the battery voltage stabilizing and adjusting system, so that the battery can quickly absorb excess power as a large capacitor to achieve the effect of voltage stabilization.
