在规定的循环寿命测试制度下，分析电动两轮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，循环记录电动两轮车锂离子4816-B动力电池800次的实时容量数据。
2.数据处理
2.1实时预警
基于电动两轮车锂离子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
通过分析两轮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 specified cycle life test regime, this dataset analyzes the capacity retention rate, discharge capacity attenuation status and corresponding capacity change rate of power batteries for electric two-wheelers, aiming to evaluate the performance attenuation, stability analysis and service life prediction of this type of battery under long-term cyclic discharge conditions.

1. Data Source
Under the specified cycle life test regime, real-time capacity data of the 4816-B lithium-ion power battery for electric two-wheelers was cyclically recorded across 800 cycles.

2. Data Processing
2.1 Real-time Early Warning
Based on the discharge life requirements of lithium-ion power batteries for electric two-wheelers, 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 recorded cycles, continue the cycle until 800 cycles are completed, and use the data from the 800th cycle for capacity retention rate calculation;
- If the real-time capacity drops below 60% of the initial capacity and an early warning is triggered during the cycle, use the data at the time of the early warning as the termination capacity to end the test in advance.

2.2 Performance Attenuation 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 Attenuation 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 attenuation status and corresponding capacity change rate of power batteries for electric two-wheelers, this dataset can be used to evaluate the performance attenuation of this type of battery under long-term cyclic discharge conditions, conduct battery performance stability analysis, and predict battery service life.
