On November 5, 2025, an open class in the format of student project defense was held in group TKS 22-1K of the Department of “Radio Engineering and Telecommunications” at ALT University named after Mukhamedzhan Tynyshbaev, under the supervision of ALT Associate Professor Bakhytzhan Estemesovich Mamilov.
Topic of the open class:
“Modeling Charge and Discharge Processes of Batteries / Virtual Battery Testing”
During today’s open class, the charge and discharge processes of accumulator batteries (AB) were simulated in a special virtual environment. The participants studied the changes in battery characteristics over time, the influence of internal resistance, capacity degradation, and charging algorithms in a practical format.
Through virtual testing, the operating modes of the battery, temperature effects, and the relationship between current and voltage were analyzed, and tests were carried out in conditions close to real industrial environments.
In addition, the purpose of using batteries in telecommunication equipment and their operating principles were discussed. Batteries provide a constant DC power supply to ensure uninterrupted operation of communication networks. In the telecommunications field, the –48 V DC standard is commonly used, ensuring network safety and stability. In case the main power supply is interrupted, the battery automatically switches on, allowing the equipment to continue operating without interruption.
This session enabled participants to:
✅ Understand the theoretical and practical foundations of battery operation
✅ Conduct system analysis by modeling charge/discharge dynamics
✅ Master the mechanisms of uninterrupted power supply in telecommunication infrastructure
