According to the electric heater heat management method and system, the readable storage medium and the electronic equipment, a flow sensor is replaced by the temperature sensor, the anti-interference performance of the electric heater heat management system is improved, the service life of the electric heater heat management system is prolonged, and collapse of the heat management system caused by failure of the flow sensor is avoided; an error source of the electric heater is considered, an actual mass flow feedback model based on a multiple regression analysis method and a least square method is established, errors are reduced, and the robustness of a thermal management system is improved; in view of the problem that the connection between working conditions is lack of control due to the fact that the working conditions of an electric heater are different due to different operation states of a new energy automobile, input power needs to be independently set for each working condition; the input power calculation value is calculated according to the current mass flow obtained through calculation of the actual mass flow feedback model, then the real-time input power of the electric heater is reversely and dynamically adjusted, and the situation that the performance and the service life of the electric heater are affected by sudden change of the input power is effectively avoided.
本发明提供的电加热器热管理方法、系统、可读存储介质及电子设备,通过温度传感器代替流量传感器,提高电加热器热管理系统的抗干扰性和使用寿命,避免因流量传感器失效导致热管理系统崩溃;考虑电加热器本身自带的误差来源,通过建立基于多元回归分析法和最小二乘法的实际质量流量反馈模型减小误差,提高热管理系统的鲁棒性;考虑到新能源汽车运作状态不同导致电加热器工况不同需要针对每个工况单独设置输入功率而导致工况之间的衔接缺少控制的问题,通过构建热管理控制函数,根据实际质量流量反馈模型计算得到的当前质量流量计算输入功率计算值,进而反向动态调整电加热器的实时输入功率,有效避免输入功率突变影响电加热器性能和使用寿命。
