This dataset focuses on analyzing the correlation between ambient temperature and the charging efficiency of lead-acid batteries, providing a critical basis for optimizing temperature adaptability for the company (as a lead-acid battery manufacturer) and external stakeholders, with remarkable application value. Its specific application values are reflected in the following aspects:
1. Optimize charging parameter settings: The company can develop differentiated charging voltage and current control strategies by analyzing the correlation between temperature and charging efficiency, adjust charging parameters according to different temperature conditions, thereby improving the charging efficiency of batteries under various ambient temperatures and extending battery service life.
2. Guide the selection and usage of charging equipment: This dataset can provide scientific references for charging equipment manufacturers and end-users, supporting their decision-making in aspects such as temperature compensation function selection for chargers, charging environment optimization, and operation and maintenance, helping users properly use lead-acid batteries according to actual temperature conditions.

1. Data Collection: Real-time recording of charging efficiency test data for lead-acid batteries under different ambient temperatures, including fields such as test sample ID, test time, ambient temperature (℃), and charging efficiency (%).
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 charging efficiency field in dataset X.
3. Calculation of Correlation Coefficient:
(1) Based on dataset X (with ambient temperature as the independent variable and charging efficiency as the dependent variable), use the CORREL function to calculate the correlation coefficient r between ambient temperature and charging efficiency.
(2) The value range of the correlation coefficient r is [-1, 1]. The closer its absolute value is to 1, the stronger the correlation between the two variables; the closer its absolute value is to 0, the weaker the correlation between the two variables.
4. Result Application: If |r| ≥ 0.8, it is judged as "strong correlation"; if 0.5 ≤ |r| < 0.8, it is judged as "moderate correlation"; if |r| < 0.5, it is judged as "weak correlation".
