The Center for Advanced Life Cycle Engineering (CALCE) and the Department of Electrical Engineering (EE), Syed Babar Ali School of Science and Engineering (SBASSE), at Lahore University of Management Sciences (LUMS) have recently started a research collaboration in the field of batteries and reliability. This partnership will support the research of Doctoral Students Huzaifa Rauf and Hayder Ali from Lahore University of Management Sciences. 

SBASSE is the first private research-focused school of science and engineering in Pakistan and stands out as one of the region’s top schools. Much like CALCE, SBASSE practices a no-boundaries philosophy, which encourages cross-disciplinary collaborations. The school’s impressive scholars and its global collaborations make it a great partner in furthering battery research.

Huzaifa Rauf concentrates on the storage reliability improvement of EVs through machine learning techniques

EVs can play a pivotal role in climate change mitigation through the decarbonization of the transportation sector. However, electrical storage is still a bottleneck with many well-documented issues with prevalent Li-ion batteries including environmental degradation, capacity fade, ageing-induced degradation, and end-of-life repurposing. These factors play a pivotal role in the cost of EVs and directly affect their uptake. 
The current collaboration includes innovative research on the development of accurate estimation models for battery performance, maintenance, prognostics, and health management. It utilizes machine learning (ML) techniques which provide a significant developmental scope to estimate the best parameters and approaches that cannot be identified using conventional techniques. The current strategy includes a non-invasive approach with low computation and high accuracy to model battery degradation.

 

 

Hayder Ali concentrates on the Impact of Energy Intensive Apps on in-service Smart Phones

There has been increasing usage of smartphones with energy-intensive apps such as social media, gaming and video conferencing/streaming. For instance, a record 62 million downloads of video calling apps were reported in March 2020. These apps are generally energy-intensive and put a significant strain on the smartphone battery, causing reliability issues such as temperature to rise, resulting in slow operation and sometimes causing unexpected shutdowns. Other battery reliability issues, such as premature shutdown and thermal runaway, may also be seen in certain circumstances. 
It is therefore critical to accurately model the phone performance and reliability during in-service (active) operation and recommend algorithms to improve battery performance. The research focuses on an experimental investigation to measure and evaluate the operational charge/discharge profile, temperature, and terminal voltage of energy-intensive apps and features, such as video calling and gaming, in the in-service operation of various smartphone manufacturers, such as Apple, Samsung, and Vivo. Our research also assesses different apps' short- and long-term effects on smartphone battery life. In addition, the investigation will be done on the influence of the app's algorithm on energy efficiency in terms of operational performance.
