Can the BYD Qin DM run without charging?
3 Answers
The BYD Qin DM can operate without charging. When the battery level drops below a certain point, the vehicle primarily relies on its engine for power. The BYD Qin is a high-performance sedan independently developed by BYD Co., Ltd., featuring the second-generation DM technology that allows switching between pure electric and hybrid modes. Below are some details about the BYD Qin DM: Introduction 1: The DM version inherits the family's Dragon Face design theme, characterized by a large grille-style front fascia adorned with multiple horizontal chrome strips, giving the front end a more refined visual appeal. Introduction 2: The headlights on both sides feature a matrix-style design, exuding a sharp and dynamic feel, complemented by the newly added air vents below, which highlight a sporty theme.
Yesterday I took my sister's Qin DM on a business trip, covering 650 kilometers without charging once. The hybrid design of this car is ingenious—it keeps running even without a charging port, as the engine automatically charges the battery to maintain a minimum 15% charge. On the highway, the actual fuel consumption was 5.8L, and in city traffic, it was just over 6L. However, remember to set the SOC to forced charge retention; otherwise, the system will foolishly prioritize battery consumption. My monthly fuel cost is around 800 yuan, 30% cheaper than my neighbor Lao Wang's fuel car. No need to worry if you don’t have a home charger.
Mechanical enthusiast here to explain the principle: The Qin DM can run perfectly fine without charging. Its engine comes with a generator module, automatically activating range-extending mode when the battery is low, while the wheel-side motor operates as usual. Lab data shows a full-tank comprehensive range exceeding 1000km, with fuel consumption when the battery is depleted being about 8% higher than the fuel version (approximately 6.5L/100km). Key points to note: acceleration response slows by 0.3 seconds in battery-depleted state, and air conditioning cooling power drops by 15%, but it's perfectly fine for daily commuting. A three-month no-charging test showed only a 0.5% drop in battery health, proving it's more durable than pure electric vehicles.
