The test drive model is equipped with a 70kWh ternary lithium battery pack provided by Contemporary Anpu Technology Co., Ltd., with an energy density of 135Wh/kg. During the test, we switched the vehicle to energy-saving mode and started the external circulation of automatic air conditioner. The temperature is set at 24℃, all the windows are closed, and the sound system is also closed.
Since it is a test, we must measure the limit. We tried our best to consume the battery power. When we drove the car to the charging station, the meter showed that there was still 4% power. The charging port on the passenger side is DC fast charging. It takes 2 hours from the start of charging to the stop of charging, and the charging amount is 6 1. 17 kWh. At this time, the battery in the car shows 100%. So the charge from 0% to 100% should be 63. 17 kWh, which is somewhat different from the official capacity of 70kWh. We also take 63. 17kWh as an important reference data, and make the following measured calculations.
In the road section test, we started from the starting point of G7 Jingxin Expressway, arrived at the Sixth Ring Road, and started to drive southwest along the expressway. During the period, the road was smooth, and the driving assistance functions such as adaptive cruise were not turned on. Acceleration and deceleration depend entirely on human operation. The final measured power consumption per 100 kilometers is 20.5 kW/h. According to the official 70kWh battery capacity, the actual cruising range of the vehicle is about 34 1 km. If calculated according to the previous capacity of 63. 17kWh, the actual cruising range of the vehicle is about 308km.
Before testing the power consumption of urban road conditions, we experienced a power exchange service that Weilai was proud of. We can find the nearest power exchange station through the car map or Weilai APP, and we can check the current queuing situation. Compared with the charging pile, its biggest advantage is its high speed, and the whole power exchange process takes about 10 minutes. What needs to be spit out is that the attitude of the power station staff is not as good as expected. Because I haven't experienced the power exchange service before, I don't know much about the ordering process. Asked about the staff, the other party was impatient. I hope this is just an example.
When the battery is changed and ready to leave, the battery inside the car shows 95% and the battery life is expected to be 409km. It should be noted that the battery with 100% capacity cannot be replaced by the power exchange service. Like this, 95% power is enough, and some car owners have switched to batteries with 80% power. At this moment, I feel very happy
During the test in the city, we didn't run the whole loop, but the main road and the auxiliary road alternated and passed through the city center, trying to restore the average speed of daily commuting. The final measured power consumption per 100 kilometers is19.2 kw/h/h. According to the officially announced battery capacity of 70kWh, the actual cruising range of the vehicle is about 364 kilometers. If calculated according to the previous capacity of 63. 17kWh, the actual cruising range of the vehicle is about 329 kilometers.
According to the test results, there is still a certain gap between the actual cruising performance of Weilai ES6 and the cruising range given by the government. At present, NEDC cruising range can only be used as a primary reference, and whether this reference standard needs to be extended is also an open question. At present, pure electric vehicle owners are more or less anxious about mileage. Before the battery technology breaks through the bottleneck, they can only rely on the later service system to protect the interests of car owners. A series of services such as battery replacement, door-to-door charging and battery upgrade launched by Weilai have played a positive leading role in the new energy market.
