BYD Qin

Highlighted Features

Power:
In hybrid mode, the BYD Qin achieves an acceleration of 0 to 100 kilometers per hour in just 5.9 seconds, with a top speed of 185 km/h. Its combined fuel consumption is as low as 2 liters per 100 kilometers. In pure electric mode, the Qin can travel continuously for 70 kilometers, meeting daily commuting needs. Even after the electric range is depleted during long-distance travel, it can still be driven independently by the 1.5TID powertrain, overcoming the limitation of insufficient driving range in new energy vehicles.

The Qin adopts BYD’s DMII dual-mode hybrid system, which operates in parallel mode. This means the system can be driven in pure electric or gasoline-electric hybrid mode.

1. Engine: The prominent power source in the Qin is BYD’s recommended 1.5L TI engine, featuring direct injection and turbocharging. It delivers impressive performance with a maximum power output of 154 PS (113 kW) at 5200 rpm and a maximum torque of 240 N·m at 1750-3500 rpm. Compared to the previous DM1’s 1.0L naturally aspirated engine, it offers significantly improved power while maintaining good fuel efficiency.

2. Transmission: The BYD Qin is equipped with a self-developed 6-speed DCT dry dual-clutch automatic transmission. Theoretically, it reduces power loss while maintaining smooth gear shifting. However, the durability of the dry clutch will require time to prove.

3. Hybrid System: According to BYD, the Qin’s hybrid system can charge the battery pack through an external power source, making it a plug-in hybrid. In hybrid mode, the system theoretically operates in pure electric mode (EV mode) for 90% of the time, with the engine entering fuel mode in only 10% of situations. This control logic maximizes fuel efficiency and minimizes overall fuel consumption.

Battery:
The BYD Qin is equipped with BYD’s lithium iron phosphate (LiFePO₄) battery. The total voltage is 500V, with an energy capacity of 13 kWh. The LiFePO₄ battery cells have a voltage of 3.2V, so the total number of cells in series is 500/3.2 = 156. Considering this, the recalculated total voltage is 499.2V. The capacity is 26 amp-hours (Ah), calculated as 13000/500. Therefore, if the battery system employs parallel connection, the capacity of each individual cell is 26 Ah.
