Description

Technical Field

[0002] With the rapid development of new energy sources, battery usage scenarios are expanding. To better approximate real-world usage scenarios, it is often necessary to simulate real-world charge and discharge behavior in subsequent battery tests based on actual battery data to verify cycle life and energy efficiency. This simulated data is often presented in spreadsheet format, requiring users to combine this data with process flow charts for charging and discharging. This data is not only massive but also complex and variable, with one or even multiple dimensions. Traditional process flow editing of this data is not only highly complex but also inefficient and prone to errors, making subsequent inspections a significant workload. Furthermore, many upstream battery companies provide test procedures to battery manufacturers in common file formats such as Excel, CSV, or TXT.
