What is the pure electric range of BYD Qin Plus DM-i?
1 Answers
The range exceeds 1000km, with a tested fuel consumption of 4.6L per 100km when the battery is depleted. The BYD Qin is a high-performance sedan independently developed by BYD Company Limited, featuring the second-generation DM technology (which allows switching between pure electric and hybrid modes). Battery capacity: The most direct factor affecting the range of an electric vehicle is undoubtedly the battery capacity. A larger battery capacity allows for a longer range. However, as the battery capacity of new energy vehicles increases, the weight of the battery also increases. Since additional weight leads to reduced range, this can become counterproductive. Therefore, the energy density of the battery is also a crucial factor in determining its quality. Higher energy density means that the battery can store more electricity per unit volume or weight. For two batteries of the same capacity, the one with higher energy density will be lighter. Drag coefficient: The drag coefficient refers to the amount of air resistance a vehicle must overcome while driving, which directly affects the power output during operation. Previous studies have shown that when a car is moving at 60 km/h, 60% of the power is used to overcome air resistance. Therefore, a lower drag coefficient means less resistance, resulting in relatively lower energy consumption. Features like hidden door handles, closed front grilles, and optimized wheel designs found in some current models can effectively reduce the vehicle's drag coefficient.
