The ideal one, which is positioned as a medium and large-scale SUV, is a new energy vehicle with a high degree of concern. Long endurance, large space and intelligent configuration are its advantages, with 6 and 7 seat models available. The power side of the ideal one is included in the category of vehicle models, so its pure electric endurance and fuel consumption must also be concerned by everyone. This time, we test the pure electric endurance and fuel consumption of the ideal one. This paper is the pure electric endurance test part. The general PHEV model only supports slow charging, but the ideal one supports both slow charging and fast charging, which is very convenient for public use. According to official data, slow charging takes 6 hours to fully charge; while in the fast charging state, it only takes 30 minutes to charge the power from 20% to 80%. We use the fast charging pile to fully charge the ideal one. The official pure electric range of ideal one is 180km, and the instrument panel displays 180km after full charge, which is consistent with the official data. After charging, carry out the preparation before the test. First, check the tire pressure value. The tire pressure of all four vehicles is 2.5bar, which is consistent with the tire pressure value required by the vehicle nameplate, and also meets the requirements of later test standards and recommended tire pressure values of vehicles. The air conditioner in the car is set to 22 ℃, and the air volume control is 2 grids, which is switched to the external circulation mode. The vehicle has two levels of energy recovery adjustable: "standard" and "strong". It needs to be adjusted to the "strong" state throughout the test. Driving power preference we choose comfort, steering force is also comfortable. It is necessary to explain that at present, the ideal one software system mainly includes three driving modes: extended range mode, hybrid mode and electricity retention mode. Among them, the extended range mode can be understood as pure electric mode, hybrid mode is oil electric hybrid mode, and electricity retention is the priority to use oil and electricity. Then the average energy consumption and subtotal mileage are cleared and the test is officially started. The test route is the outer ring road of Guangzhou University, with a single ring road of about 15km, asphalt pavement, 16 traffic lights, speed limit of 60km / h in the whole section, basically simulating the suburban road conditions. We will record the accumulated mileage, endurance and power consumption every 30 minutes. In the test process, the ideal one has three different driving modes: extended range mode, hybrid mode and power holding mode. We need extended range mode for the whole test. In the extended range mode, the vehicle adopts pure electric drive. The extender will not be activated until the remaining power of the vehicle is less than 17%. The speed limit of university town is 60km / h. on the premise of no violation, we try to improve the speed during the test, adopt the habit of daily driving, two drivers alternate driving, and reduce the test error as much as possible. The drive motor with a total torque of 530nm has a good acceleration effect for the ideal one. The whole acceleration process is very linear, and there is not too much abrupt feeling. Even with the "strong" kinetic energy recovery setting, the drag force is moderate, and the braking deceleration is close to the feeling of the fuel vehicle. After 126.9km driving, the power battery shows that there is still 17% left and the meter shows that the pure electric endurance is 31km left. At this time, the vehicle automatically activates the range extender. Therefore, when the remaining 17% power is measured, the pure electric range of the ideal one is 126.9km, while the official data is that it can drive 180km with pure electric power when the power is used up. It is worth mentioning that the pure electric endurance of 126.9km currently ranks first in our PHEV model list. In addition, the average power consumption of the vehicle is 16.8kwh/100km, which is not high. At the end of the test, we charged the vehicle from 17% to 100% with the fast charging pile. The total charging time is 1 hour and 15 minutes, the charging degree is 30.20 degrees, and the charging efficiency is not high. According to the charging degree and the actual pure electric endurance, the actual average charging power consumption of the ideal one is 23.8kwh/100km. It should be noted that the "driving power consumption" displayed in the ideal one car does not include the energy consumption of other electrical equipment such as vehicle air conditioner. From the charging chart, we can see that the charging power of the vehicle is close to 60kW at the beginning of charging, but with the increase of time and SOC, the charging power will gradually decrease. The charging power for most of the time is about 15kw. When the SOC is close to 100%, the power of trickle charging will be maintained at about 6kW. The SOC quantity of the start and stop in the figure above is the data provided by the charging point of special call, and we will take the actual vehicle table display as the standard. It can be seen from the test data record that from the beginning to the end of the test, the indicated endurance consumption is always greater than the actual mileage. And with the increase of test time and driving distance, the gap between the two is growing. In general, the apparent endurance of the ideal one is relatively weak. summary
