Russian scientists develop model to extend battery lifespan

By Ahmad El-Assasy Researchers at Tomsk Polytechnic University (TPU), together with colleagues from Novosibirsk, have developed a digital model that allows real-time assessment and adjustment of battery operating conditions in electric buses. According to TV BRICs , this innovation can significantly increase battery life by accurately accounting for thermal and electrical processes. This is reported by the official website of the Russian Ministry of Education. The model was created as a result of comprehensive research, including field tests of transport, collection of operational data and mathematical modelling of battery degradation processes. Key parameters were taken into account: charge level, temperature fluctuations, number of passengers and speed of movement. "Our model combines physical and chemical modelling, statistics and neural network approaches. It adapts to specific routes, taking into account climate and charging modes, which allows us to optimise battery performance in real time," explained project leader Nikita Martushev, associate professor at the TPU School of Information Technology and Robotics. Field tests were conducted on urban and suburban routes, during which dozens of parameters were recorded, from charge level and temperature to engine torque. Based on the data obtained, the scientists built a mathematical model of the traction system that allows them to assess the impact of temperature and electrical modes on battery wear. The results showed that a 15°C increase in temperature reduces battery life by 30 per cent, and operation at 43°C reduces it by almost half. Accelerated charging or discharging twice as fast as normal reduces the battery life by 30 per cent, and four times faster reduces it by 47 per cent. The study also identified the optimal operating conditions: a charge level of 25% to 65% and a temperature range of 20–30°C. Additional charging stations along the route allow battery heating to be controlled and significantly slow down their wear and tear. read more Gold prices rise, 21 Karat at EGP 3685 NATO's Role in Israeli-Palestinian Conflict US Expresses 'Strong Opposition' to New Turkish Military Operation in Syria Shoukry Meets Director-General of FAO Lavrov: confrontation bet. nuclear powers must be avoided News Iran Summons French Ambassador over Foreign Minister Remarks News Aboul Gheit Condemns Israeli Escalation in West Bank News Greek PM: Athens Plays Key Role in Improving Energy Security in Region News One Person Injured in Explosion at Ukrainian Embassy in Madrid News China Launches Largest Ever Aircraft Carrier Sports Former Al Zamalek Player Ibrahim Shika Passes away after Long Battle with Cancer Videos & Features Tragedy Overshadows MC Alger Championship Celebration: One Fan Dead, 11 Injured After Stadium Fall Lifestyle Get to Know 2025 Eid Al Adha Prayer Times in Egypt Business Fear & Greed Index Plummets to Lowest Level Ever Recorded amid Global Trade War News Flights suspended at Port Sudan Airport after Drone Attacks Videos & Features Video: Trending Lifestyle TikToker Valeria Márquez Shot Dead during Live Stream News Shell Unveils Cost-Cutting, LNG Growth Plan Technology 50-Year Soviet Spacecraft 'Kosmos 482' Crashes into Indian Ocean Arts & Culture "6 Ayam" Sets Streaming Date
