The invention relates to the field of heat management control and calibration of new energy automobiles and in particular relates to a calibration method and a calibration system for radiator performance parameters, which can solve the problems of time consumption and complicated modification of cooling systems of conventional radiator performance parameter calibration tests. The calibration method for radiator performance parameters comprises the steps that an air supply device makes intake air speed of a test vehicle achieve target air speed; a heating device makes inlet temperature of a radiator achieve target temperature; when the inlet temperature of the radiator is at the target temperature, performance parameters of the radiator are calibrated. By using the air supply device to simulate intake air condition of a test vehicle and using a heating device in the test vehicle to accurately simulate a constant temperature water tank in a wind tunnel experiment, calibration tests of radiator performance parameters can be performed without modifying cooling systems, so that test expenses in complete vehicle development is effectively reduced, the development period of complete vehicles is shortened and the efficiency of complete vehicle development is improved.
Description
technical field [0001] The invention relates to the field of thermal management control and calibration of new energy vehicles, in particular to a calibration method and a calibration system for radiator performance parameters. Background technique [0002] The thermal management system is an essential part of new energy vehicles. The system can monitor new energy vehicles from an overall perspective, so that all key components can work at a suitable temperature to ensure the smooth operation of new energy vehicles, thereby providing drivers with Good driving experience. For example, the thermal management system can monitor the temperature of the drive motor and power battery in real time and make reasonable adjustments when the temperature is too high or too low to keep the drive motor and power battery at a certain temperature level during driving. Usually, the main way for the thermal management system to adjust the temperature of new energy vehicles is to coordinate th...
