Building a battery charging speed prediction model for low-speed electric vehicles in North China during winter enables clear understanding of regional battery charging efficiency, thereby formulating differentiated strategies to improve the operating efficiency of low-speed electric vehicle battery systems. This model can accurately predict regional charging demand and charging speed during winter. Efficient charging facility layout can meet users' charging needs, reduce waiting time, and improve user satisfaction. Additionally, understanding differences in charging speed across regions helps optimize power configuration of charging equipment to ensure efficient operation of charging facilities. The data facilitates scientific battery management and maintenance, timely identification of abnormal charging states, extension of battery lifespan, and reduction of maintenance costs. Analyzing charging speed data across regions and seasons also allows development of targeted user service strategies to enhance user experience and increase management revenue. 1. Data Collection: The original data comes from the company's business collection data, including original data fields such as battery voltage (V), battery capacity (Ah), State of Health (SOH, %), initial State of Charge (SOC, %), target SOC (%), ideal operating voltage (V), actual operating voltage (V), ideal charging current (A), actual charging current (A), etc. 2. Algorithm Rules: By establishing the battery charging speed prediction model for low-speed electric vehicles in North China during winter, the basic performance parameters of the battery, actual operating conditions, as well as the impacts of region and season are comprehensively considered. 1) SOH factor = 0.95 − 0.005 × (100 − SOH); 2) Rated energy (kWh) = (battery voltage (V) × battery capacity (Ah)) / 1000; 3) Actual energy (kWh) = rated energy × SOH factor; 4) Energy to be charged = actual energy × (target SOC/100 − initial SOC/100); 5) Actual charging power = actual operating voltage × actual charging current / 1000; 6) Basic charging time (hours) = energy to be charged / actual charging power; 7) Voltage factor (η_V) = 1 − 0.001 × |actual operating voltage − ideal operating voltage|; 8) Current factor (η_I) = ideal charging current / actual charging current; 9) The actual charging time adopts a function mapping model: actual charging time = f(basic charging time, η_V, η_I, SOH factor, region, season).
