This dataset focuses on analyzing the impact of discharge cut-off voltage on the capacity of lead-acid batteries, revealing the quantitative relationship between termination voltage setting and battery service life, and providing key discharge management basis for the company (as a battery manufacturer) and external relevant stakeholders, with significant application value, which is specifically reflected in the following aspects:
1. Optimizing battery discharge management strategies: The company can scientifically set discharge termination thresholds by analyzing the impact of different cut-off voltages on capacity, ensuring available capacity while avoiding over-discharge damage, thereby significantly extending battery cycle life and maintaining its performance stability.
2. Guiding the development of battery management systems: This dataset can provide references for Battery Management System (BMS) R&D enterprises, equipment manufacturers and system integrators, supporting them in optimizing voltage protection points, improving state-of-charge estimation algorithms, predicting battery health status and other related work, and promoting the development of lead-acid battery application systems towards intelligent and precise management.

1. Data Collection:
Real-time recording of lead-acid battery capacity test data under different discharge cut-off voltages, including fields such as test sample number, test time, discharge cut-off voltage/V, and battery capacity/Ah.
2. Data Preprocessing:
(1) Denoise the collected data to ensure data accuracy.
(2) Aggregate the historically collected data (including this collection) to form dataset X, and calculate the average value of the battery capacity field in dataset X.
3. Calculating Linear Regression Slope a and Intercept b:
(1) Based on dataset X (with discharge cut-off voltage as the independent variable and battery capacity as the dependent variable), use the SLOPE function to determine the slope a based on the principle of least squares, and use the INTERCEPT function to determine the intercept b.
(2) The slope a represents the degree of influence of unit discharge cut-off voltage change on battery capacity, and the intercept b represents the capacity value of lead-acid battery under the reference discharge cut-off voltage.
4. Result Application:
(1) Calculate the proportional coefficient k: k = |a / average battery capacity| × 100%.
(2) If k ≥ 7%, it is judged as "high impact"; if 4% ≤ k < 7%, it is judged as "medium impact"; if k < 4%, it is judged as "low impact".
