HJ12L摩托车起动电池启动耐久性数据

在规定充电、放电制度下，分析HJ12L摩托车启动电池的放电电压衰减情况、在启动放电下的温控性能以及对应参数的变化率，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
在规定的充放电制度下，循环记录36000次的65A放电2s的电压，和电池内部的温度。
2.数据处理
2.1实时预警
基于启动电池放电2S电压和电池内部温度性能要求，通过设置监测阈值并实现智能预警，当循环至放电电压＜8.0V结束循环，或者当循环至电池内部温度>40℃结束循环；
2.2性能衰减变化率
采用以下公式计算性能衰减变化率：
（1）放电电压变化率=(放电终止电压-放电结束电压)/放电终止电压；
（2）电池内部温度变化率=(电池终止温度-电池内部温度)/电池终止温度；
当测试结束时，若循环记录36000次中均没有预警，则放电终止电压和电池终止温度取36000次的数据，若循环过程中进行预警，则采用预警时的数据作为放电终止电压和电池终止温度

Under the specified charging and discharging regimes, this dataset analyzes the discharge voltage attenuation, temperature control performance under start-up discharge, and change rates of corresponding parameters of the HJ12L motorcycle starting battery, 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
Cyclically record the 65A 2s discharge voltage and the internal temperature of the battery for a total of 36000 cycles under the specified charging and discharging regimes.

2. Data Processing
2.1 Real-time Early Warning
Based on the performance requirements for the 2s discharge voltage and internal temperature of the starting battery, monitoring thresholds are set to enable intelligent early warning. The cyclic test will be terminated if the discharge voltage drops below 8.0V, or if the internal temperature of the battery exceeds 40℃.

2.2 Performance Attenuation Change Rate
The following formulas are adopted to calculate the performance attenuation change rates:
(1) Discharge voltage change rate = (Discharge termination voltage - Discharge end voltage) / Discharge termination voltage;
(2) Battery internal temperature change rate = (Battery termination temperature - Battery internal temperature) / Battery termination temperature;
At the end of the test, if no early warning is triggered throughout the 36000 cycles, the discharge termination voltage and battery termination temperature will be extracted from the data of the 36000th cycle. If early warning is triggered during the cyclic test, the data collected at the time of early warning will be used as the discharge termination voltage and battery termination temperature.

3. Data Application
By analyzing the discharge voltage attenuation of the motorcycle starting battery, the temperature control performance under start-up discharge, and the change rates of corresponding parameters, this dataset supports the evaluation of performance attenuation, battery performance stability analysis and service life prediction of this type of battery under long-term cyclic discharge conditions.
