The aircraft battery is a very important onboard component of the aircraft. During flight, when the main power supply and other auxiliary power sources fail, the onboard battery is needed to supply power to important equipment, radio stations, and instruments on the aircraft, in order to maintain the aircraft's flight to the nearest airport for landing. According to airworthiness regulations, onboard batteries must be able to maintain power supply for at least half an hour (Etop flight time is one hour), and batteries with a capacity less than 85% are not allowed to be installed on the aircraft. Aircraft batteries are time and space accessories that must be removed from the aircraft for testing, charging, and capacity testing after a certain period of installation.

At present, most aircraft generally use alkaline cadmium nickel batteries, which have better performance than lead-acid batteries in all aspects, but are also expensive. According to the survey, the service life of aircraft batteries in Chinese airlines, especially small and medium-sized airlines, mostly does not reach the design life of the battery, and some are even less than a quarter of the service life. The reason is due to inadequate charging methods or charging equipment. Research and practice have shown that the charging process of a battery has a significant impact on its lifespan, while the discharge process has a relatively small effect. Therefore, adopting the correct charging method and charging device, and regularly testing the discharge performance of the battery can effectively extend its lifespan and ensure the safe operation of the aircraft.

Product Description

Intelligent battery charging and discharging machine (charging+discharging test+battery maintenance)

The intelligent battery charging and discharging machine (aviation) is a comprehensive device developed by our company specifically for aircraft batteries (lead-acid and cadmium nickel alkaline batteries, lithium batteries). It integrates charging, discharging, fast charging, and testing. It is not only suitable for testing the charging and discharging capacity of on-board batteries of large civil aviation aircraft such as Boeing and Airbus, but also for testing the charging and discharging capacity of on-board batteries of large and medium-sized helicopters, business jets, Cessna, Challenger, Gulfstream, Bell, Sikorsky, Euroclass, McDonnell Douglas, Bell, Hawker Beech, Pilatus, Y-5, Y-12, Z-9, Z-10 and other series of aircraft and other aircraft. It is versatile. Intelligent charging mode, realizing automatic conversion between constant current and constant voltage; Accurate testing of battery capacity through constant current discharge enables maintenance personnel to have a clear understanding of battery performance; Optimizing the adjustable intermittent pulse fast charging method can greatly accelerate the chemical reaction rate of the battery, shorten the time for the battery to reach full charge, and improve the efficiency of battery use; Effectively ensure the safety of their work. LCD display, intelligent control, detection and display of all test data: current, battery pack voltage, duration, capacity, temperature, etc. The data is transferred to a USB flash drive and matched with data processing software to display and print various charts.

Main features and functions of intelligent battery discharge device

● Display mode: Large LCD screen display, Chinese menu prompts, real-time display of all test data: voltage, current, capacity, duration, and internal temperature, etc.

Control method: Controlled by a microcontroller, set parameters such as the protection voltage, discharge current, discharge capacity, and discharge duration of the entire battery pack through the keyboard.

● Automatic shutdown function: Automatically stop discharging when any of the following conditions are met: time, capacity, and protection voltage.

● Automatic alarm function: It will automatically sound an alarm when there is high temperature or disconnection of the battery pack connection.

Real time monitoring function: Real time display and control of various set parameters (such as voltage, current, time, capacity, etc.).

● Record query function: The discharge meter can store 8 sets of discharge data (10 hours per set), and users can query according to their needs.

● Data transfer function: It has standard USB interface and RS232 interface. After the discharge is completed, the data can be directly uploaded to the computer through USB flash drive or RS232 interface, solving the problem of large capacity data storage.

Data processing function: After the discharge data is analyzed and processed by the supporting data processing software, various curve charts can be automatically generated and printed.

● Computer remote control function: discharge parameters can be set and modified through the computer; Control the discharge device to start and stop discharging.

● Parallel function: Two or more discharge meters of the same model can be connected in parallel by a parallel panel (optional accessory). Each machine operates independently and has flexible control methods.

Calibration and correction function for voltage and current display values: mainly used to calibrate the total voltage and current of the battery pack.

The power consuming components use specially made alloy resistors with high power density, no open flames, safe and reliable, and long lifespan.

Utility model patent: Feedback type power lithium battery formation and group detection system.

Integrated design of control circuit and power consumption components, compact size, easy to carry, and forced air cooling for heat dissipation.

● Extended function: Used in conjunction with our company's online monitoring device for battery pack parameters, it can detect the voltage of individual batteries, calculate battery internal resistance and remaining capacity, in order to more accurately detect deteriorating batteries and ensure the reliability of battery pack operation.

Data processing software

Directly obtain the discharge information of the discharge meter, process and analyze it, and generate current curve graphs, voltage curve graphs, detection data, etc., which can be output to HTML, Excel, and Word to form test reports, and support printing for convenient user archiving. Based on these charts, the performance trend of the battery pack can be viewed, providing a scientific basis for judging the quality of the battery pack.
