Study on Airborne Battery Ground Maintenance System

An airborne battery ground maintenance method was proposed and a ground maintenance system was developed in order to meet the airborne battery ground maintenance needs, which based on the basic principles of battery maintenance, combined with PCI bus technology, and digital power supply, electronic load and other digital devices with MODBUS, SCPI protocol. The system, which solved the traditional single function and lack of systematic reviews and other issues, achieved the onboard battery charge maintenance, discharging maintenance and charge-discharge cycle maintenance (activated), to ensure the operation of the safety, while achieving the battery safety assessment through the voltage, current, capacity, and time of process parameters the detection and analysis. Experimental results showed that the system, maintains voltage range of 0-35V, maintaining current range of 0-4A, the maximum reference error less than 0.1% , accuracy class G of 0.1, met the airborne battery ground maintenance needs, effectively ensuring the airborne battery stable and reliable operation in emergency use.
