What is the range of the BYD Song Pure Electric?
2 Answers
The range of the BYD Song is 405 kilometers. As a new energy vehicle, range is one of the key metrics for electric vehicles. The longer the range, the more practical the electric vehicle becomes. Several major factors affect the range of an electric vehicle: Battery Capacity: The most direct factor affecting the range of an electric vehicle is undoubtedly the battery capacity. Larger battery capacity allows for longer range. However, as the battery capacity of new energy vehicles increases, the battery weight also increases, which can lead to reduced range due to the added load. This trade-off makes energy density an important factor in evaluating battery quality. Drag Coefficient: The drag coefficient refers to the amount of air resistance a vehicle must overcome while driving, which directly affects power output during movement. Previous studies have shown that at a speed of 60 km/h, 60% of a car's power is used to overcome air resistance. Therefore, a lower drag coefficient results in less resistance and relatively lower energy consumption. Vehicle Weight and Load: Heavier new energy vehicles place greater loads on bearings and tires, leading to increased rolling resistance. This requires more energy during acceleration, thereby affecting range. Research has shown that reducing the weight of a new energy vehicle by 100 kg can increase the range by 10-11%, while also reducing battery costs by 20% and daily wear costs by 20%.
I've been driving the BYD Song EV for several months now. The official CLTC range is 605 kilometers, but in daily use, it's far from achievable. In city driving with frequent stops and starts, the average range drops to around 450 kilometers before the warning light comes on. On the highway, when the speed exceeds 100 km/h, the power consumption spikes, reducing the range to below 380 kilometers. In winter, the battery is particularly sensitive to cold, and turning on the heater directly cuts the range to 350 kilometers. It's better in cooler summer weather. If charging is convenient, such as having a home charging station, I recommend keeping the battery level between 20% and 80% to prolong battery life and maintain more stable range. Overall, it offers good value for money, but don't expect the advertised numbers—test drive it in real-world conditions when choosing a car.
