Review compares lithium-ion battery state-of-charge estimation methods
—
in EngineeringWhat the study found This paper reviews methods for estimating the state of charge (SOC), meaning the remaining charge, of lithium-ion batteries in electric vehicles. It describes the approaches in terms of their algorithms, mathematical models, strengths, weaknesses, and error rates. Why the authors say this matters The authors say SOC is an essential parameter…
PTFE membrane showed lower thermal stress than Nafion
—
in EngineeringWhat the study found Using PTFE (polytetrafluoroethylene, a heat-resistant plastic) membrane instead of Nafion in a fuel cell reduced thermal stress by 44% in the study's simulation. Why the authors say this matters The abstract says membranes are necessary for fuel-cell chemical reactions, and that temperature changes generate thermal stress that affects membrane performance. The…
V2G cycling impact on lithium-ion cell lifetime depends strongly on temperature
—
in EngineeringStudy quantifies lithium-ion cell degradation from vehicle-to-grid cycling using real-world EV charging data, revealing that shallow V2G cycling at moderate depths maintains cell functionality.
