With the rapid development of the low-speed electric vehicle (LSEV) market, accurately grasping the influencing factors of battery lifespan has become particularly critical. For Battery Management System (BMS) development, this dataset can be used to formulate charge-discharge strategies, design thermal management systems, regulate battery balancing, and develop lifespan prediction algorithms. In terms of vehicle operation management, the data can optimize fleet charging scheduling, develop maintenance plans, monitor battery health status, and evaluate usage costs. For product design optimization, this dataset provides important guidance for heat dissipation system design, charging system matching, and performance parameter optimization. By analyzing lifespan driving factor data, manufacturers, distributors and end users can better understand and manage battery lifespan. This dataset and its analysis results are primarily targeted at the daily operation and management of low-speed power batteries. Through the rational application of this data, the service life of batteries can be effectively extended, operational efficiency optimized and costs effectively controlled, which holds significant practical significance for promoting the healthy development of the low-speed electric vehicle industry. 1) Temperature stress calculation: Temperature stress = Reference stress (1.0) + Temperature deviation coefficient; 2) SOC stress calculation: SOC stress = Reference stress (1.0) + SOC over-limit stress + SOC range stress. For SOC lower than 20%: 0.02 additional stress per 1% decrease; for SOC exceeding 80%: 0.02 additional stress per 1% increase; 3) Rate stress calculation: Rate stress = Reference stress (1.0) + Charging rate stress + Discharging rate stress; 4) Capacity retention rate calculation: Capacity retention rate = 100% - (Temperature stress + SOC stress + Rate stress) × Number of cycles / 100; 5) Remaining lifespan prediction: Predicted remaining lifespan = Nominal lifespan (8 years) × (Current capacity retention rate / 100%).
