Hardware Related Influencing Factors and Optimization of Charging Efficiency

With the rapid popularization of portable electronic devices (such as smartphones and tablets) and the accelerating adoption of electric vehicles globally, the demand for fast, efficient, and stable charging solutions has become increasingly urgent.This paper focuses on analyzing the key hardware factors that determine charging efficiency, centering on two core components: chargers and batteries.For chargers, it evaluates three critical metrics-power conversion efficiency, heat dissipation capability (discussing overheating protection triggers and component aging risks), and output parameter stability (linking stability to charging continuity, safety, and device lifespan).For batteries, it explores how cell material ionic conductivity (lithium ion vs. lithium iron phosphate (LFP) batteries, electrolyte performance) and structural design (packaging, tab layout) influence ion/electron transfer efficiency.Based on these analyses, the paper proposes targeted optimization directions: using GaN/SiC materials for chargers, enhancing thermal management and output stability, and innovating battery materials (high nickel ternary, lithium manganese iron phosphate (LMFP), silicon carbon composites) and structures (lamination process, full tab design).The study acknowledges limitations, including the neglect of software, environmental factors, and cost considerations, and suggests future research focus on hardware and software integration.
