The invention discloses a parameter calibration device and method for a vehicle electric heating system. The device comprises an environmental chamber, an enthalpy difference wind tunnel, an electric heater, a warm air pipeline, an air conditioner module, a power supply and a control module, the power supply is connected with the electric heater, cooling liquid is arranged in the warm air pipeline, and the electric heater is used for heating the cooling liquid; a first measuring module is arranged in the enthalpy difference wind tunnel, and the air conditioner module is used for blowing heat of the heated cooling liquid into the enthalpy difference wind tunnel; the first measuring module is used for measuring the air outlet flow and the air outlet temperature of the air conditioner module. The control module is used for determining the air side heat absorption capacity according to the air outlet flow and the air outlet temperature, determining the consumed power of the electric heater corresponding to each set of control variables and the liquid side heat release capacity, and determining the target cooling liquid flow and the target air conditioner air outlet capacity according to the consumed power, the liquid side heat release capacity and the air side heat absorption capacity. According to the method, the target cooling liquid flow and the target air conditioner air outlet volume at the required environment temperature can be selected, and parameter calibration is achieved.
