When Huawei is also putting chips on the extender, everyone should sweat for EV products.
Some people say that the extender is the product of imperfect technical form and second,000, based on the fact that this is a technology of burning oil to generate electricity and using electricity to drive, which is equivalent to taking off the pants and putting x.
Moreover, electric vehicles also have to burn oil, which is simply a shame, and there is a deviation in the understanding of electric vehicles.
Yes, the use of internal combustion engines to generate electricity, and then the electric drive vehicles, the theory is not wrong, there is more than one process, but from a rational point of view, charging and installing internal combustion engines to generate electricity, strictly speaking, are a way to replenish energy.
Where does the electricity our pure electric vehicles need come from? According to the current way of obtaining electricity, a large part is still thermal power generation, not to mention the pollution and waste pollution generated by thermal power generation, and how much waste can be generated during operation.
If the generator is directly moved to the car, is it less wasteful from the entire electricity production process?
Moreover, the traditional engine work efficiency is not high, one is the extreme thermal efficiency is very low, the other is the high thermal efficiency operation range is narrow, in order to cope with different road conditions and driving needs, in most cases, the efficiency of the engine is very low.
However, the internal combustion engine of the extended range structure has a high thermal efficiency, such as the ideal ONE, although it is a domestic 1.2T small three-cylinder, but the comprehensive thermal efficiency of the engine is close to 35%, and the power generation efficiency is more than 90%, which is not low.
Objectively speaking, this engine is not very strong, but it is already in good condition, and if it is replaced by a small displacement engine of Nissan and Toyota, the efficiency can be better.
For example, Nissan's e-Power architecture exclusive engine, because of the realization of the thermal efficiency and output power of the constant operation of the goal, the ultimate thermal efficiency is 50%, under normal circumstances, there is also 40%.
This means that this technical architecture is feasible, the comprehensive pollution is the least, there is no charging trouble in the direct sense, and according to the law of conservation of energy, the electricity of pure electric vehicles must be converted through other channels, so how much pollution is generated by other channels?
Huawei has long entered the zengcheng market.
Whether it is the SF5 of the year or the M5 that appears today, it is a set of positive range extended range architecture, a high thermal efficiency internal combustion engine, a set of battery packs, the main role of the internal combustion engine is to drive the generator to generate electricity, and the electricity generated is supplied to the motor to drive the vehicle.
The advantage of this architecture is that the engine is constantly in a stable and high-efficiency state, and anything is about efficiency, and this structural state is not bad.
It is more fuel-efficient than fuel vehicles, and from the general structure of electric vehicles, it does not need to increase the burden on external electrical energy, and at the same time, it can also save the trouble of no charging pile.
The current new energy direction structure has been very obvious.
One is the field of pure electric vehicles, the absolute king of the technical direction, one is the plug-in hybrid architecture, with BYD DM-i as the technical representative, plug-in oil strategy, low fuel consumption and long endurance, the other is the extended range architecture, in fact, the extended range is a kind of plug-in, the difference is that the internal combustion engine acts as a generator, burning oil to generate electricity, so that the motor works.
Looking at something new with a key attitude always leads to a better outcome.
The result of the range increase is the same as that of the plug-and-mix model, although the technical form is easier to understand, but if you want to do a good job in the reliability and stability of each step, while ensuring lower fuel consumption and higher power generation efficiency, you still need to promote technology, rather than keyboard typing can be completed.
Those who say that the extended range architecture is chicken ribs, do you know how to improve the thermal efficiency from 40% to 41%?
