Problems solved by technology
Once the battery is short of power during the test, it will have many adverse effects on the test results of the vehicle; especially in the process of vehicle performance and emission testing, the increase in generator load will have many adverse effects on fuel consumption and emissions. The validity of the test results is reduced. If the temporary charging device is activated, it will cause problems such as battery overheating and rapid battery loss. The test items cannot be carried out normally, which greatly reduces the test efficiency and there are hidden dangers of charging safety.

The invention relates to the technical field of automobile charging, and specifically discloses a charging device and a charging method. The charging device is used for charging the test vehicle, the test vehicle is provided with an ECU module, the charging device includes a first power supply, a charger, a stand control module, a relay and a display module, and the relay is configured to be connected to the first power supply and the charger respectively , the charger is used to charge the battery of the test vehicle, the display module is used to display the power of the battery, the bench control module is connected to the ECU module, the display module and the relay respectively, and the bench control module is configured to When the storage battery is in a state of power shortage, the control relay is turned on so that the charger can charge the storage battery. The charging device can charge the test vehicle in time to ensure that the test vehicle has sufficient power when the test vehicle is tested again, improves the test efficiency, and has high safety.
Description
technical field [0001] The invention relates to the technical field of vehicle charging, in particular to a charging device and a charging method. Background technique [0002] During the test of the test vehicle on the powertrain bench or the vehicle hub, due to problems such as electrical loss or abnormal state of the sample wiring harness, it often occurs that the battery of the test vehicle is insufficient. Once the battery is short of power during the test, it will have many adverse effects on the test results of the vehicle; especially in the process of vehicle performance and emission testing, the increase in generator load will have many adverse effects on fuel consumption and emissions. The validity of the test results is reduced. If the temporary charging device is activated, it will cause problems such as battery overheating and rapid battery loss. The test items cannot be carried out normally, which greatly reduces the test efficiency and there are hidden dangers...
