One point of view, both plug-in hybrid and plug-in hybrid have a good suppression of the fuel consumption of the internal combustion engine, why can't the former be regarded as a new energy vehicle?
In the domestic market, the hard criterion for defining whether it is a new energy vehicle is whether the cruising range in pure electric mode can reach more than 50km, and it is obvious that the hybrid system without plug-in hybrid is basically about 5km because it cannot be equipped with a large-capacity battery pack.
Plug-in hybrid is equipped with a larger capacity battery pack, and it is easy to run out of 50km of pure electric range, one is that the domestic CLTC test intensity is relatively weak, and the other is that as long as the battery pack capacity is more than 8kWh, it can ensure that the vehicle has a range of at least 50km.
Becoming a plug-in hybrid means becoming a new energy vehicle, and the advantages of exemption from purchase tax and no driving restrictions are almost overwhelming in front of fuel vehicles.
In fact, in terms of use, there is not much difference between plug-in hybrid and non-plug-in hybrid, the former can provide a certain mileage of pure electric driving ability, and the latter can only rely on the internal combustion engine for the whole process.
For example, the Mondeo recently unveiled an all-new E-hybrid, compared to the BYD Han DM-i, which sells well.
The characteristics of the Mondeo E-hybrid are that whether it is 10km or 1000km, it can achieve a fuel consumption performance of about 5L, and the BYD Han DM-i can run about 70km-90km of actual pure electric range when fully charged.
If the comprehensive fuel consumption of Han DM-i is also about 5L after feeding.
In fact, more plug-in hybrid models have restrictions, and the theoretical data only provides reference, for example, small battery packs generally cannot be fully charged, and they are generally charged to about 80% to stop, and the pure electric range is discounted in winter and when the air conditioner is turned on.
The real division of new energy vehicles should be from the perspective of carbon emissions.
Pure electric vehicles do not emit carbon dioxide and other pollutants into the atmosphere when driving, and truly get rid of gas stations, PHEVs, REEVs and HEVs are all carbon emission reduction products, and they still have to rely on gas stations.
Previously, the BYD Han DM-i was driven about 3,000km, with a total mileage of about 700km for pure electric driving, and the other more than 2,400 kilometers for internal combustion engine drive, with a total fuel cost of about 1,000 yuan.
A new powertrain composed of an internal combustion engine, an electric motor, and a battery can be called a carbon reduction product, and there is no technical superiority or disadvantage in nature, only different choices.
Two days ago, I test-drove the Mondeo E-hybrid, and I felt that it was the same as Toyota and Honda, a typical economic performance-oriented HEV hybrid product.
One is that its power combination is more ingenious, the combination of 1.5T engine with motor and battery pack makes the power reserved, and the acceleration performance is stable at about 7 seconds, which is the high power standard of EA888.
The other is that the fuel consumption is not high, the data of CLTC is that the fuel consumption is about 4.5L per 100 kilometers, and there is no problem with the fuel consumption control at about 5L in the case of improper daily movement of roadblocks.
The logic is to use a combination of motor + battery to work in the low-speed working interval where the thermal efficiency of the internal combustion engine is low, such as starting, U-turning, and stopping, and the internal combustion engine directly drives the vehicle when accelerating and cruising at high speed.
Compared with the 2.0L and 2.5L engines of other HEVs, the 1.5T engine has a stronger reacceleration ability, especially when cruising at a speed of 60km/h and 70km/h, and the engine speed is not high, and the fuel consumption and power are taken into account to a certain extent.
If you take a step back and compare the 2.0T fuel version of the Mondeo, in the case of similar acceleration ability, the fuel consumption can be reduced from 8L to 5L for daily use, and the fuel consumption reduction capacity of about 60% can be regarded as a very excellent technology in carbon emission reduction.
In fact, the purpose of equipping the internal combustion engine with an electric motor is to avoid the low thermal efficiency of the internal combustion engine and make the thermal efficiency of the internal combustion engine higher in the state of comprehensive use.
The difference is that HEVs cannot be licensed on new energy license plates, and cannot be driven in pure electric mode during short-distance trips, but it is also the case that their lower weight, higher reliability, and lack of constraints by charging piles also bring convenience to daily use.
In the European market, the definition of PHEV is becoming more and more stringent, because a large number of consumers are driving PHEVs as gasoline vehicles, and the ability to emit pollutants into the atmosphere is the same as that of diesel engines.
