Currently, the battery pack consistency evaluation indicators are unclear and are roughly divided into single-parameter and multi-parameter evaluations. Single-parameter evaluation usually uses voltage or SOC to characterize the consistency of the battery pack .
The consistency evaluation method needs to be applicable to batteries with different aging paths and different health states. For subsequent error analysis and method verification, this paper uses 18,650 cells to perform 0.3C, 0.5C, 1C, 1.5C, and 2C cycle tests at 25 °C, 35 °C, and 45 °C to simulate batteries in different health states.
