Fast charging control method and system for drone nests

Abstract

This invention provides a method and system for fast charging control of drone nests. By adjusting the environment inside the nest to achieve a suitable charging environment for the battery, it acquires real-time information on the charger's own temperature, charging voltage, and charging current, as well as information on the battery's single-cell voltage and temperature. It analyzes the charging SOC curve and controls the charging voltage and current in real-time based on the charger and battery status. It adds over-temperature, short-circuit, over-voltage, and over-current protection functions and promptly feeds abnormal information back to the background alarm via the drone nest. When the drone is about to enter long-term storage, the low-charge battery will be charged to the storage voltage, or the fully charged battery will be discharged to the storage voltage before power is cut off for storage. This invention achieves real-time sensing of the nest's internal temperature, ensuring charging and discharging within the set temperature range, reducing safety hazards, and avoiding the problem of reduced battery life caused by storing fully charged batteries.

By obtaining the next task time, the charging mode is selected according to the storage time of the aircraft. In the task mode, full charging is performed, and in the storage mode, quantitative charging or discharging operations are performed, which improves battery life and avoids power waste. The division of charging stages and real-time monitoring of the working status of the battery and charger further improves the safety of charging and battery.

[0085] 3. This invention innovatively proposes a fast charging control system for UAV nests, comprising at least: a nest control terminal and a charger control terminal, an ambient temperature regulation terminal, and a battery control terminal, each communicating with the nest control terminal. The nest control terminal and the charger control terminal each execute their respective control strategies. The battery control terminal handles battery anomalies. The battery status parameter monitoring system acquires battery status information in real time, intelligently analyzes the battery SOC, and adjusts charging according to the battery status. On the other hand, it can monitor battery anomalies and promptly trigger protection circuits to protect the battery and the entire nest from safety accidents. The system selects the charging mode based on the UAV's upcoming operating state, which is beneficial for battery storage and can effectively extend battery life. Attached Figure Description

[0169] The battery control terminal is configured to: read the battery voltage, single-cell voltage, and battery temperature and send them to the battery cell control terminal and / or charger control terminal; sequentially perform overvoltage detection, overcurrent detection, and short-circuit detection; when overvoltage occurs, perform overvoltage protection and stop charging or discharging; when overcurrent occurs, perform overcurrent protection and stop charging or discharging; when short circuit occurs, perform short-circuit protection and stop charging or discharging; when no overvoltage, overcurrent, or short circuit occurs, determine whether charging or discharging is complete; if so, the process ends; otherwise, return to continue reading the battery voltage, single-cell voltage, and battery temperature.

[0170] Specifically, such as Figure 3 and Figure 4 As shown, the nest control terminal and environmental control equipment are included. The nest control terminal controls the battery charger via a relay and communicates with the environmental temperature control terminal, such as an air conditioner, which is controlled by the nest control terminal.

[0171] The drone battery charger does not include a charger control terminal, a charging module, or a temperature measurement unit. The charger control terminal can read the current charger temperature, communicate with the battery to obtain battery parameter information, and communicate with the drone control terminal to transmit temperature information to the drone control terminal. The charger control terminal is connected to the drone control terminal through a relay to realize charging control.

[0172] The drone battery mainly consists of a battery control terminal, an analog front-end acquisition module, a battery protection module, and an equalization circuit module. The battery control terminal mainly performs signal processing, control, and communication functions. The analog front-end acquisition module mainly collects parameters such as battery voltage, charging current, discharging current, single-cell voltage, and battery temperature. The battery protection circuit module uses signals to control relays to allow or prohibit charging and discharging. The equalization circuit mainly collects the voltage of individual cells and charges each cell evenly to achieve a balanced state.

[0173] This embodiment controls the air conditioning to adjust the environment inside the drone's storage compartment to achieve a suitable charging environment for the battery. It then acquires real-time information on the charger's own temperature, charging voltage, and charging current, as well as information on the battery's single-cell voltage and temperature. It intelligently analyzes the charging SOC curve and controls the charging voltage and current in real time based on the charger and battery status. In addition, this method adds over-temperature, short-circuit, over-voltage, and over-current protection functions by setting temperature detection, short-circuit detection, and over-voltage and over-current detection. Abnormal information is promptly fed back to the background alarm through the drone's storage compartment. When the drone is about to enter long-term storage, the low-charge battery will be charged to the storage voltage or the fully charged battery will be discharged to the storage voltage before power is cut off for storage.

[0174] The specific charging control process is as follows:

[0175] Step 1) Before issuing the charging command, the device checks whether the ambient temperature meets the charger's operating temperature range;

[0176] Step 2) If the operating temperature range is not met, turn on the environmental conditioning device to make the battery environment meet the charger's operating temperature range; otherwise, proceed directly to step 3).

[0177] Step 3) Turn on the charger. The charger performs a self-test and selects a charging mode. The self-test includes a communication self-test with the nest control unit and reading its own temperature to determine the charging status based on the task situation. Select the charging mode.

[0178] Step 4) Read parameters such as battery voltage, charging current, single-cell voltage, and battery temperature in real time, and perform SOC analysis;

[0179] Step 5) Monitor battery temperature. When the charger temperature or battery temperature exceeds the set threshold but does not exceed the abnormal temperature limit, pause the charging process, wait for a period of time, and then re-enter Step 1). If the abnormal temperature limit is exceeded, stop charging and report the abnormal situation to the background.

[0180] Step 6) Perform overvoltage, overcurrent, and short circuit monitoring; if any abnormality is detected, prohibit or disconnect charging.

[0181] Step 7) Determine whether the battery should enter the first charging stage (pre-charging) based on the remaining battery voltage;

[0182] Step 8) Determine whether to enter the second charging stage based on the remaining battery voltage: constant current charging, repeat steps 5) to 7).

[0183] Step 9) Determine whether to enter the third charging stage based on the remaining battery power: constant voltage charging, repeat steps 5) to 7).

[0184] Step 10) Determine whether to enter the third charging stage based on the remaining battery power and charging status: charging is stopped;

[0185] Step 11) When the remaining battery power is detected to be higher than the storage voltage, the charger enters the battery discharge state until the battery voltage is discharged to the optimal storage voltage and then stops working.
