Abstract

In work, the process of monitoring of the electric variable on a 14 Ah prismatic LiFePO4 battery has been carried out. The variables monitored include electric current, voltage, energy and internal resistance to be analyzed for its effect on the temperature variable on the battery. An analysis of the relationship between the increase of temperature and the efficiency of energy has also been done. This process succeeded in getting the electrothermal value or heat arising from the electric variable in the battery. In the end, the values obtained would be processed using machine learning with SVM and Random Forest methods

基于机器学习的电池温度变化率估计
在工作中,对14ah柱形LiFePO4电池进行了电变量的监测过程。监测的变量包括电流、电压、能量和内阻,分析其对电池温度变量的影响。分析了温度升高与能量效率之间的关系。该方法成功地获得了电池中由电变量产生的电热值或热量。最后,使用SVM和Random Forest方法对得到的值进行机器学习处理
