电动自行车动力4820-A电池寿命分析数据

在规定的循环寿命测试制度下，分析电动自行车动力电池的容量保持率、放电容量衰减情况对以及应容量的变化率，用于评估该类型电池在长时间循环放电情况下的性能衰减情况、电池性能稳定性分析以及电池使用寿命预测。1.数据来源
在规定的循环寿命测试制度下，循环记录电动自行车动力4820-A电池800次的实时容量数据。
2.数据处理
2.1实时预警
基于电动自行车动力电池放电寿命要求，通过设置监测阈值并实现智能预警，当测试结束时，若循环记录600次中均没有预警，则继续循环至800次，容量保持率取800次的数据；若实时容量低于初始容量60%时，循环过程中有进行预警，则采用预警时的数据作为终止容量，结束循环；
2.2性能衰减变化率
采用以下公式计算电池性能变化相关的参数：
（1）容量保持率=实时容量/初始容量*100%；
（2）容量衰减率=（初始容量-终止容量）/初始容量*100%；
（3）容量变化率=(终止容量-实时容量)/终止容量；
3.数据应用
通过分析电动自行车动力电池的容量保持率、放电容量衰减情况对以及应容量的变化率，用于评估该类型电池在长时间循环放电情况下的性能衰减情况、电池性能稳定性分析以及电池使用寿命预测。

Under the standardized cycle life test regime, this dataset analyzes the capacity retention rate, discharge capacity decay, and capacity change rate of power batteries for electric bicycles, aiming to evaluate the performance degradation, analyze battery performance stability, and predict the service life of this type of battery under long-term cyclic discharge conditions.
1. Data Source
Under the standardized cycle life test regime, real-time capacity data of the 4820-A power battery for electric bicycles was cycle-recorded over 800 cycles.
2. Data Processing
2.1 Real-time Early Warning
Based on the discharge life requirements of power batteries for electric bicycles, monitoring thresholds are set to enable intelligent early warning. At the end of the test, if no early warning is triggered during the first 600 cycles, the test will continue until 800 cycles, and the capacity retention rate will be calculated using the data from the 800th cycle; if the real-time capacity drops below 60% of the initial capacity and an early warning is triggered during cycling, the data at the time of early warning will be used as the termination capacity to end the test.
2.2 Performance Decay Change Rate
Parameters related to battery performance changes are calculated using the following formulas:
(1) Capacity Retention Rate = (Real-time Capacity / Initial Capacity) × 100%;
(2) Capacity Decay Rate = [(Initial Capacity - Termination Capacity) / Initial Capacity] × 100%;
(3) Capacity Change Rate = (Termination Capacity - Real-time Capacity) / Termination Capacity;
3. Data Application
By analyzing the capacity retention rate, discharge capacity decay, and capacity change rate of power batteries for electric bicycles, this dataset is used to evaluate the performance degradation, analyze battery performance stability, and predict the service life of this type of battery under long-term cyclic discharge conditions.
