|
摘要
为给出考虑整车参数和实际工况时系统的电动汽车驱动电机动态温升计算方法,在概括主要研究思路的基础上,给出了电动汽车驱动电机动态温升研究方法的具体实现过程。首先,将实际电机的特性曲线嵌入到在Advisor整车系统中,基于拉格朗日极值定理,建立逆动态电流解耦模型,实现了运行工况下考虑整车参数的电机瞬态电流提取;其次,将工况电流作为Ansys温度场模型的输入,计算了实际行驶时驱动电机的动态温升;最后,搭建实验测试平台进行实验测试。实验结果和仿真结果显示了很好的一致性,证明了所提电动汽车驱动电机动态温升计算方法的准确性和有效性。
This study aims to achieve the whole calculation method for the dynamic temperature rise of the driving motor in electric vehicle( EV) considering the parameters of the vehicle and the practical conditions. Based on the summary of the main research ideas,the temperature rise of the drive motor in EV at driving condition is proposed. First,the characteristic curve of the actual motor is embedded in the entire vehicle system of the Advisor. The Lagrange Extreme Value Theorem is utilized to formulate an inverse dynamic current decoupling model. The motor instantaneously current considering the vehicle parameters is extracted at driving conditions.Secondly,the extracted operating current is adopted as the input of the Ansys temperature field model. The dynamic temperature rise of the drive motor during practical driving is calculated. Finally,an experimental test platform is set up for testing. The experimental and simulation results have the characteristics of compliance. The accuracy and effectiveness of the proposed dynamic temperature rise method for EV drive motors are verified.
