Advantages and disadvantages of plug-in hybrid electric vehicle

Plug-in cars have the following advantages and disadvantages:

Advantages of plug-in cars:

1, the oil saving effect is good

The biggest feature of hybrid vehicles is "fuel saving". Among the hybrid vehicles on sale in the market, the hybrid vehicles of Prius, Camry and Lexus CT200h have the best market response. The new generation Prius is equipped with a 1.8L engine, and its fuel consumption per 100 kilometers has dropped to 4.3 liters. The recently launched Camry hybrid has a fuel consumption of 5.3 liters per 100 kilometers, which is 32% less than the Camry gasoline model with the same displacement.

2. Strong endurance

Compared with plug-in hybrid vehicles, under the premise of imperfect infrastructure such as charging piles, the purchase and use of hybrid vehicles are more convenient and easy to operate. At the same time, the endurance of hybrid vehicles is much higher than that of plug-in hybrid vehicles.

3, the maintenance cost is low

Although the maintenance cost is the same as that of the gasoline version, it will be higher than that of the ordinary car, especially the battery, which is expensive once it is damaged after the warranty period. Similarly, taking Camry as an example, all Camry models enjoy a three-year or 100,000-kilometer vehicle warranty, and the battery of Zunrui hybrid models can enjoy a five-year or 200,000-kilometer warranty. If the battery fails within the above-mentioned period, the manufacturer will guarantee or replace the car with a brand-new battery. If the battery is replaced beyond this period, it will cost about 20,000 yuan.

Disadvantages of plug-in cars:

1. There are few models to choose from.

At present, among automobile enterprises, Toyota is the first enterprise to vigorously develop hybrid technology, and the hybrid models on sale include Camry, Prius and Lexus CT200h h. In terms of independent brands, independent brands including Changan, Chery and SAIC Roewe have launched hybrid vehicles. Unfortunately, these models are not only "short-lived" in the market, but also stop in the fields of rental and official vehicles. There are very few models available for consumers to choose from in the market.

2, the car price is high and the subsidy is low.

The cost of plug-in hybrid vehicle is relatively high, mainly because it relies on the traditional engine structure, and the development of engine start-stop technology and energy recovery technology in the field of racing tends to be mature for many years. After the technology was decentralized to the passenger car field, after the development and evolution of several generations of models, the technology became more mature. Due to the low cost of MHEV hybrid system, the government’s policy on new energy vehicles is inclined, and its cost performance is still excellent.

3. High maintenance cost

For the models with two hybrid technologies, the most direct factors that consumers consider are the maintenance rate of used cars after five years and the maintenance cost in daily use. From the perspective of the surplus value of used cars in five years, the MHEV hybrid version has certain advantages, because the plug-in hybrid version has a high battery utilization rate, which reduces its service life to a certain extent. Moreover, the plug-in hybrid version has a defect that it is prone to power loss. Although various manufacturers have adopted multiple spare batteries to prevent power loss, once the battery is damaged, it will be a great maintenance cost. At present, the residual value of used cars of hybrid models in the market after three years is about 40%, and the loss is still relatively large.

4, daily use of plug-in hybrid is a bit cumbersome.

In the daily use process, plug-in hybrid power is difficult to charge simply by relying on the energy recovery of the engine because of its large energy reserves, and the battery is in a state of power loss for a long time, which is very harmful to the battery life. Therefore, plug-in hybrid power system needs consumers to use it frequently and charge it with an external power supply. At present, there are two kinds of charging methods: fast charging and slow charging, which need professional charging stations to charge. But at present, most garages in sub-districts do not have hardware standards for establishing fast charging stations, and the time for slow charging is usually 6-8 hours, which sometimes affects the travel of car owners.

5. Expand information:

Who is more suitable for oil-electric hybrid or plug-in hybrid?

At present, the hybrid new energy vehicles on the market mainly include MHEV hybrid vehicles and plug-in hybrid vehicles, and various manufacturers have also launched corresponding products. The advantages of the two technologies complement each other, and they shine brilliantly in the field of mid-level cars and performance cars respectively. But now, with the continuous decentralization, more models have enjoyed the technical supplement, so how should ordinary consumers choose the products of these two technologies in their daily lives?

At present, the mainstream MHEV oil-electric activity system is a 48V power supply system, which supplies energy through engine power recovery. After the engine start-stop system works, the power supply system works to help the engine start and stop smoothly and provide energy for additional power supply facilities such as air conditioners. Plug-in hybrid provides a relatively high-power motor, and uses energy recovery and external power supply at the same time. The engine and motor can work at the same time and provide a high-performance mode, which is the mainstream development trend of MHEV hybrid system at present.

MHEV hybrid research and development costs are low, and the starting price of products is low.

For the two hybrid systems, the cost of MHEV hybrid system is relatively low, mainly because it relies on the traditional engine structure, and the development of engine start-stop technology and energy recovery technology in the field of racing tends to be mature for many years. After the technology was decentralized to the passenger car field, after the development and evolution of several generations of models, the technology became more mature. Due to the low cost of MHEV oil-electric hybrid system and the development of several generations of vehicles, the average technical price of its products in the market has decreased. Although the current MHEV oil-electric hybrid system and the government’s policy on new energy vehicles are inclined, its product cost performance is still excellent.

In terms of ride comfort and driving quality, MHEV oil-electric hybrid is more dominant.

No matter what kind of hybrid technology, it is to help the vehicle achieve better driving texture, power and handling. When the engine is started and stopped, the MHEV hybrid system can reduce the vibration of the engine, improve the ride comfort of the whole operation, and provide better driving texture. Although the MHEV hybrid electric system will not change the overall power of the engine and can not effectively improve the running power, it can obviously improve the driving quality of the whole vehicle. This is why many luxury brand models will introduce the MHEV hybrid system version after the change.

Plug-in hybrid pure electric driving is more environmentally friendly.

As for normal urban road conditions, how much contribution do the two hybrid technologies make to fuel consumption? From the working principles of the two technologies, the MHEV hybrid electric system only improves the energy efficiency and converts the energy into the energy of the motor and power supply system. Taking an intermediate vehicle as an example, the fuel consumption can be reduced by about 1L per 100 kilometers, which is more obvious for the mature Japanese hybrid electric system. Plug-in hybrid power can provide nearly 50 kilometers of pure electric mileage, and the effect of fuel saving is more obvious. Taking the main driving speed range and mileage of the city as a reference, the daily fuel consumption reduction in urban transportation will be amazing.

To sum up, plug-in hybrid power system, because of the advantages of pure electric mileage, its fuel consumption is more dominant, for future energy emissions.
