The model participating in the test this time is the BMW iX3, equipped with a leading model of 80kWh, NEDC has a range of 500km, we are fully charged, and the measured cruising range is 464km.
The winter endurance test standards and environment are as follows:
All vehicles maintain the same planting weight, according to the weight of the people on board, using mineral water counterweight.
Tire pressure is consistent across all vehicles
All vehicles depart with full power (SOC: 100%).
The temperature on the day was 10 °C - 18 °C (the weather was so hot that we were helpless)
All vehicles maintain uniform air conditioning settings, synchronous on and off.
All vehicles are prohibited from opening windows throughout the vehicle.
Assisted driving is used throughout the process, with a work vehicle as the headcart, and the ACC speed is set at 105km.
The standard mode is used throughout the whole process, and the kinetic energy recovery is medium.
After the vehicle power limit, take the initiative to leave the team and drive at the maximum limit speed until the nest.
The endurance results of 12 electric vehicles are shown in the figure:
Travel distance after power limitation:
BMW iX3 drivers share the performance of the model after the power limit:
The BMW iX3 still traveled 6 kilometers after the meter range was 0 kilometers. The power of the table is limited, but in the ground driving, the actual power of the vehicle is not limited, at least at the maximum speed of the ground is still strong, after acceleration can obviously feel the feeling of pushing back, and still achieve overtaking on the ground road.
Due to the speed limit on the surface road, the vehicle can still maintain a speed of 60km/h one second before the vehicle is completely broken, so there is no obvious power limitation during the entire trip, and when the power is felt, the next second the vehicle breaks down.
Although the table shows that the power is limited, but there is no power limit in the actual driving, which will make the driver unable to judge how many kilometers the vehicle can travel after the table is 0, I think there is still an actual power limit, so that you can judge whether to wait for rescue nearby or park the vehicle in a safe place, I hope that in the later stage, in addition to the table, there can be some other power limitation tips.
