In the past four months this year, oil prices have already risen seven times. Now the oil price we are afraid that everyone has seen for all to see, I have to say that as a big crude oil importer, the oil producing country will have a big cold if it blows a little wind, not to mention that in recent days, the oil producing countries have come to a tornado, and the domestic oil price has been directly swept up in the sky.
Oil prices are about to break the ten yuan mark, and the raw materials for new energy vehicles have also risen. Tesla has experienced the third round of price increases, and the price of mineral products such as nickel and lithium directly related to ternary lithium batteries is also rising, after all, in this international situation, no bulk product can stand alone. But for ordinary people, travel cars are just needed, whether it is to work, or weekend travel, a car can directly increase their travel radius several times. Driving a fuel car wallet is painful, driving an electric car and worrying about the charging station, so is there a choice, you can choose "I want it all" in high oil prices and endurance anxiety?
Obviously, electric drive is an efficient way of driving, but this does not mean that the electric drive of the car must only rely on charging energy supply. For example...... Hybrid.
Electric drive torque is more powerful
Hybrid is not a new technology, it has been applied as early as 76 years ago, the closest to the actual application is the German "Mouse" tank.
At the end of the war, the Germans began to build a super heavy tank weighing more than 100 tons, and if the vehicle was driven directly by an engine, the early gasoline engine-driven version could only walk at 15 kilometers per hour. In order to achieve higher speeds, Porsche, which participated in the design, opted for an electrically driven tank, charging the battery with an engine that could reach speeds of up to 25 km/h.
In modern electric-driven vehicles, electric vehicles tend to accelerate faster than fuel vehicles at the same price point because they can reach maximum torque at the start. Historically, even on 100-ton giants, electric drives are equally applicable. With electric drive, the vehicle can be adjusted steplessly and the power output is smoother.
More choices in the space
In addition to being powerful, another big benefit of hybrid is that it is easy to maneuver the space. Vehicle energy is mainly transmitted by wires, which are bendable, so the engine and electric motor can be placed in the appropriate position.
Fuel vehicles are different, horizontal and vertical layouts directly affect the performance of the vehicle, and some vehicles' engine drive shafts also need to occupy valuable space inside the car, resulting in a bulge in the center of the car.
On naval ships, after replacing components such as drive shafts and transmissions with cables, the internal space can be greatly expanded, and the noise is smaller, which is more suitable for battleships.
Britain's Type 45 destroyers and Queen-class aircraft carriers, the United States' Zumwalt-class destroyers all use all-electric propulsion, and China's 055-class destroyers are also under development.
Reasonable arrangement can reduce the size of the car's power compartment as much as possible, leaving as much space as possible for passengers, and avoiding the central bulge, and the complex fuel tank and exhaust arrangement of the chassis can also be simplified.
Quieter driving
When driving a fuel vehicle, when starting and when idling at low temperatures in winter, it is often louder, and the noise will be reduced after the vehicle starts, which is caused by changes in engine load and speed. Although this phenomenon does not directly affect driving, it does affect comfort and high-quality.
Hybrid vehicles are different, the engine is always running within a stable load and speed range, the noise can be kept at a low level at any time, and the idle jitter phenomenon will be greatly improved.
Easy speed-up, more space arrangement options, and better NVH performance are all advantages that hybrids have found in long-term applications.
In the hybrid vehicle, BYD is an unavoidable topic, due to the development of a blade battery that is not inferior to the ternary lithium battery, and the DM-i hybrid system is installed on the car, BYD has become a fragrant food in the hybrid car.
Different from the general hybrid vehicle, DM-i hybrid will not use the engine after the battery is exhausted, but will intervene in the engine power when the battery power is low, and help the motor drive the wheel while charging to ensure that the vehicle will not have an extreme power loss. In the oil-electricity conversion, it can be guaranteed to be smooth enough.
More importantly, due to the use of lithium iron phosphate batteries, less affected by international commodities, the current bydir of BYD Tang DMi hybrid price has been lowered to the level of 180,000 yuan, and the previous fuel version of Tang price is close. For trams, it is not easy to achieve this level.
Because the battery is cheap and the power is sufficient, BYD currently has a version with a pure electric range of more than 100 kilometers, which is enough for daily travel, and the fuel tank and engine are left for long distances.
However, compared with the pure fuel vehicle with the same configuration, the hybrid car is still small and expensive, so is the fuel money saved enough to offset the price difference of the car? Let's do the math.
Taking the BYD Tang Hybrid Version as an example, its average fuel consumption per 100 kilometers is 5L (note that this is a achievable fuel consumption, because the more the hybrid is blocked, the more provincial); the BYD Tang fuel version, the average fuel consumption is about 10L. In other words, the hybrid version can save half of the oil money, at the current oil price, saving 4 cents per kilometer.
So what is the difference between the two? At present, the fuel version has only one configuration, and the author inquired about the hybrid version with a considerable configuration, which is about 57,000 yuan more expensive. The hybrid version is exempt from purchase tax, and the final difference is about 40,000. In other words, driving 100,000 kilometers can be saved, and normal family cars can be returned for 10 years.
In fact, this comparison is not fair, because the hybrid version is better silent, the acceleration is stronger and smoother, which is equivalent to enjoying a more advanced car in the past 10 years. In addition, BYD's hybrid car also has a 220V external discharge function, usually outings can also be roasted, wild cooking, is not very cool? In this comparison, is the hybrid version already exploded the fuel version?
