针对现有电动汽车电池状态估计方法存在运算效率低和估算准确率低的问题,提出一种模型以估算电动汽车电池荷电状态(state of charge,SOC)和健康状态(state of health,SOH)。采用堆叠降噪自编码器(stacked denosing auto encoder,SDAE)...针对现有电动汽车电池状态估计方法存在运算效率低和估算准确率低的问题,提出一种模型以估算电动汽车电池荷电状态(state of charge,SOC)和健康状态(state of health,SOH)。采用堆叠降噪自编码器(stacked denosing auto encoder,SDAE)清洗电压、电流和温度数据中的异常数据和空缺数据,减小对估算精度的影响。引入动态通道剪枝(dynamical channel pruning,DCP)技术对Informer模型进行稀疏化处理,提高剪枝后模型的性能和稳定性。将清洗过的数据输入DCPInformer模型实现SOC和SOH的精确估计。实验结果表明,所提出的SDAE-DCPInformer模型估计SOC的平均绝对误差和均方根误差分别达到0.25%和0.38%,估计SOH的平均绝对误差和均方根误差分别达到了0.51%和0.64%。与传统Transformer等模型相比,所提模型预测SOC和SOH的速度更快,估算准确度有效提升,拥有的更好稳定性和泛化性。展开更多
