How much is the difference between BYD dmi burning oil without charging and pure electricity?

When BYD's DMI (Hybrid Electric Vehicle) is only powered by fuel without charging, its operating cost lags far behind that of pure electric vehicles. Specifically:

Calorific value comparison: the calorific value of gasoline is 1.5 times that of coal, which means that gasoline with the same quality can travel less distance than fuel with the same quality. Based on the power consumption per 100 km, the cruising range of electric energy on electric vehicles is about 22 km, while the fuel of gasoline vehicles can travel about 19.57 km 1.

Economic analysis: Assuming that the fuel consumption of a BYD Dmi is 4.5 liters per 100 kilometers, under the background of oil price and electricity price, the cost under this driving mode is as follows:

Gasoline vehicle: the fuel consumption cost per 100 kilometers is 49 yuan RMB 1.

Electric car: Because the cost of electric energy is much lower than that of steam.

Oil, so the cost of 100 kilometers is only 15 RMB 1.

Cost consideration of BYD Dmi: Although BYD has excellent performance in cost control, even plug-in hybrid vehicles usually have to increase their prices by more than 20,000 yuan compared with traditional fuel vehicles with the same configuration. This is because the cost of the hybrid system is higher than that of the conventional fuel vehicle 2.

To sum up, if BYD Dmi only relies on fuel without external power supply, then it will drive every 100 kilometers.

The economic cost will be at least higher than 16.5 yuan. This difference increases with the increase of driving distance, especially in areas with no charging facilities and high power costs, which may be more significant.
