A review of Li‐ion battery temperature control and a key future perspective on cutting‐edge cooling methods for electrical vehicle applications

AbstractCovid‐19 has given us a new way to look at our globe with regards to minimise air and noise pollution and thereby upgrading global environmental conditions. This positive pandemic outcome indicates that green energy is the future of energy, and one new origin of green energy is lithium‐ion batteries (LIBs). Electric vehicles are constructed with LIBs, but they have a number of disadvantages, including poor thermal performance, thermal runaway, fire dangers and a higher discharge rate in low‐ and high‐temperature conditions. The underlying fault of LIBs is their temperature reactivity. Extreme temperatures and challenging working circumstances can cause lithium‐ion cells to malfunction and cause the battery pack (BP) to overheat. For optimal performance in vehicles and long‐term LIB durability, LIBs must be thermally managed within their operating temperature span. This paper presents an overview of several cooling strategies used to maintain the internal BP temperature. This paper discusses cooling techniques using air, liquid and phase change material (PCM), heat pipe. Additionally, various BP configurations and heat generation techniques are explored. This research also discusses the usage of nanomaterials to address the BP's heat‐related problems. This study emphasises the use of nanomaterial to boost the heat conductivity of coolant in order to raise the batteries temperature into their ideal working range (PCM as well as liquid cooling). This article also provides some of the research gaps that have been found and the crucial areas on which attention should be directed in order to build the best lithium‐ion battery thermal management system technology.

The COVID-19 pandemic has impacted the higher education sector significantly. It forced the stakeholders to do new things and brought many innovations to educational activities. As the pandemic hit the shores of many countries, among other things and sectors, education activities were disrupted. Many, not well-advanced universities in terms of technology and learning management systems (LMS) embarked on a forced recess, using the period to put online education platforms in place. The advanced universities immediately migrated contact teaching and learning to online platforms. This paper aimed to investigate the immediate effects that the pandemic has on South Africa’s higher education systems in terms of how both lecturers and students were made to use new technologies/tools, how the tools enhanced teaching and learning, how assessments transformed due to the pandemic, and if some of the interventions employed during the pandemic will find usefulness when the pandemic has finally retreated. In this study, universities that are offering engineering degrees in South Africa are used as a case study, and data were obtained from both engineering students and engineering lecturers at these universities through qualitative (survey with open-ended questions) together with quantitative (surveys with closed-ended questions) research methods. The study shows that higher education activities cannot go back to the way they were before the pandemic. The study brings to light that some old techniques will be combined with some innovations employed during the pandemic to ensure effectiveness and greater throughputs in the higher education systems going forward.
