As the country continues to launch various preferential policies for new energy vehicles, such as no lottery, no restrictions on the line, no purchase tax and so on.
Domestic consumers want to buy new energy vehicles, also become more and more up.
But many people who want to buy new energy vehicles are not very clear about the performance of new energy vehicles.
In fact, we can divide new energy vehicles into five categories: weak mixed/mild mixed, light mixed, strong mixed, plug-in electric and pure electric.
Here, the gas-electric mixing degree can be simply understood as the percentage of the power of the automotive electrical system in the total power.
As shown in the following figure, we compare these five types from different angles, and also add English abbreviations commonly seen in daily life to facilitate your understanding.
In general, with the increase of electric/oil mixing degree, gradually from weak mixing to light mixing, to strong mixing, and finally to pure electric, its fuel saving efficiency is gradually improved.
When we talk about electric vehicles, we can more accurately define them as hybrid, plug-in and battery electric vehicles in the table above.
From another perspective, the increase of electric/oil mixing degree is actually the increase of battery energy, which also corresponds to the increase of pure electric range, which is closely related to the performance of the battery.
As can be seen, from weak mixing to light mixing, to strong mixing, and then to the final pure electric battery, the battery is also from the traditional lead-acid battery, to nickel metal hydride battery, and then to lithium battery.
So, the battery is the core.
“Quality sense” new energy vehicle cost center of gravity must be in the whole power battery part, battery cost can not come down, compared with the same price fuel car in the quality of the sense must be stretched.
This difference is especially pronounced for pure electric vehicles.
Because the core pain point of pure electric cars is the endurance range, there is only one way to have enough endurance range at present. The cost of power batteries with higher energy density and larger capacity is basically one-third or even higher of the whole vehicle.
So in the whole vehicle work material configuration and even sound insulation this aspect compared with the same price fuel car is too far.
But the gap is being narrowed by progressive manufacturers.
