The design concept of "dual use of oil and electricity" makes people feel "really fragrant"

However, there are many hybrid car models.

Let many consumers make it difficult to choose.

Then follow the experts.

Understanding Hybrid Vehicle from Technical System

Choose the car that suits you best.

What is a hybrid car?

Hybrid electric vehicles are referred to as "hybrid vehicles" and generally refer toCombining the traditional internal combustion engine technology with the motor technology.As a power source, a car canSwitching power sources under different driving conditionsSo as to optimize the energy use efficiency and give consideration to the endurance of fuel vehicles and the environmental protection characteristics of electric vehicles.

According to the structural form of power system

Series hybrid electric vehicle (SHEV)

Only the engine works to drive the generator to provide drive for the motor.

√ Advantages

The engine always generates electricity in the high efficiency range, which can provide a smoother driving experience and fuel-saving effect at low speed, and the energy recovery system is also more efficient.

X shortcomings

When driving at high speed or needing high power output, the fuel consumption performance is poor, and the motor conversion efficiency is reduced, resulting in higher fuel consumption than ordinary fuel vehicles.

Parallel hybrid electric vehicle (PHEV)

The engine and motor can work simultaneously or separately.

√ Advantages

In pure electric drive mode, the use cost is low; In the hybrid drive mode, the dynamic performance is excellent.

X shortcomings

We can’t rely solely on pure electric drive for a long time, and we can’t fully reflect the economic advantages of electric new energy. In pure fuel mode, fuel consumption may be difficult to control.

Series-parallel hybrid electric vehicle (CHEV)

The engine can also generate electricity while driving the output with the motor.

√ Advantages

Combining the advantages of series and parallel technology, the fuel economy, power output energy efficiency, cruising range and driving experience are better.

X shortcomings

The overall system layout of the automobile is more complex, and the requirements for the control system are higher, so the daily maintenance cost is relatively high.

According to the external charging function

Plug-in hybrid electric Vehicle

A hybrid electric vehicle that can obtain electric energy from off-board devices under normal use.

Unplugged hybrid electric vehicle

A hybrid electric vehicle that obtains all the energy from on-board fuel under normal use.

How to choose a hybrid car that suits you?

Charging condition

√ There are charging conditions:Suggested choicePlug-in hybrid vehicle, convenient for power supply, not limited by time and place. with regard toShort daily commuteFor consumers, it can maximize the economy.

× No charging condition:It is recommended to choose an electric drive with a long cruising range and support DC fast charging.Series hybrid vehicle, series hybrid vehicle or non-plug-in hybrid vehicleWhen the power is insufficient, you can still rely on the internal combustion engine to work, which avoids the problem of mileage anxiety and reduces the inconvenience of frequent charging and charging time.

Fuel consumption situation

In addition to the actual fuel consumption performance of the car, it is recommended to choose.Low loss/feed fuel consumptionA hybrid car.

In the case of no charging, the output economy of the engine determines the use cost.

ifOften run long distances.% of consumers don’t recommend choosing series hybrid cars, because the economy of high-speed fuel consumption is relatively poor, so choose.Parallel and series-parallel hybrid vehiclesMore appropriate.

Loss of electricity and fuel consumptionRefers to the fuel consumption that depends solely on the engine for output when the automobile is exhausted or insufficient.

Feed oil consumptionRefers to the fuel consumption of the engine not only for power output, but also for charging the battery.

Power battery capacity

The sustainability of the peak power output of the motor is often limited by the output of the battery.

If necessary, often.Long distance driving, high capacity batteryThe model is a better choice;

If it is mainlyShort-distance travel in cities, you can consider choosing.Medium or low capacity batteryTo balance cost and performance.

Buying a computer is fooled into paying more money, buying a TV for one year leads to serious quality problems, and after-sales work is perfunctory and evasive. These behaviors have become the most headache for consumers. On October 29th, based on the feedback data from 96111 of Huaxi Media Call Center, the complaint information of Sichuan Consumer Council in the third quarter and the complaint cases of China Consumers Association, Huaxi Dushi Bao launched a "black list" of home appliances, which was divided into five categories: stores, computers, televisions, water heaters and water purifiers, exposing the digital home appliance enterprises with the most concentrated complaints from consumers and defending consumers’ rights to the end. Readers can also continue to call 96111 to give feedback on the consumption problems you have encountered, or pay attention to the micro-signal "I Home Appliances" of our home appliances, and we will protect your rights.

Store category and computer category: Lenovo, which sells "Water Depth" in World A, has been complained 13 times in more than 10 months.

According to the data of China Consumers Association, from the end of last year to now, there have been as many as 13 complaints about Lenovo computers in Sichuan alone, and most of them occurred in World Computer City A, mainly because of price fraud, including a price difference of as high as 1,800 yuan and quality problems, and the number of complaints far exceeded that of other brands of computers.

On the afternoon of February 27th this year, Mr. Hou, who lives in Jinjiang District, Chengdu, and his friends bought Lenovo laptops in Chengdu A World Computer City. After arriving in A World, the sales staff took them to the Lenovo store on the second floor. "I was going to buy a computer with the fourth generation of Intel i5 processor. The salesperson recommended three Lenovo brands to me, which were divided into three grades: high school and low school. I chose the middle grade and converted it to 3,980 yuan." The salesperson said that this computer is Lenovo’s all-around 50 series. "I also told me that its processor is Intel’s fifth-generation processor, and the fourth-generation processor is dual-core. This computer is quad-core and has better performance."

Mr. Hou searched online with his mobile phone on the spot, but he couldn’t find Lenovo Almighty 50 all the time. "The salesperson said that this is a new model that just came out, so I believed it. He also said that the 4-core game is absolutely stable, and the graphics card is 2g, and the system is windows8.1. I can reinstall the windows7 system, so I believed him and paid the money." However, when Mr. Hou came home, he found that this computer configuration was actually unique in 1g, and the cpu was only the processor of intel Pentium, which was far from the fourth-generation processor of Intel i5 mentioned in the store. Finally, under Mr. Hou’s repeated communication, the merchant agreed to replace the computer.

The same Lenovo computer, Mr. Wu of Chengdu also encountered a similar problem on the second floor of A World. At the end of December last year, he planned to buy Lenovo all-around 50n2980 notebook, and set the price at 4500 yuan. After payment, the sales staff lied that the n3540 computer had higher configuration performance and the price remained unchanged on the pretext that it was out of stock. After buying it back, Mr. Wu found that the n3540 model was not only low in configuration, but also the highest price of this computer on the Internet was about 2,800 yuan, and the lowest price was 2,699 yuan. For this reason, he complained that he wanted to make up the difference of 1,800 yuan.

From November 5, 2014 to September 20, 2015, the Lenovo computer purchased by Ms. Rao was replaced once and repaired three times. After two months of maintenance, it still could not be used. Its production record: the serial number of the first exchange product is: pf04y8wg, and the serial number of the new computer product after exchange is: Pf05r884, repair record and warranty are all used.

Pf04y8wg product serial number. To this end, Ms. Rao complained that Lenovo computers had factory defects and demanded compensation for return.

Since the end of last year, Dell Computer has been complained twice in Sichuan, namely, price fraud and repeated improper maintenance; Asus computer was complained twice about price fraud; Shenzhou Computer was complained of a price fraud. Color TV category:

Konka’s after-sales maintenance was controversial. After welding, it was said that the consumer was damaged by external force.

According to the information of China Consumers Association, Mr. Su bought Konka 55-inch TV with model led55f5510pf on December 24th, 2014. After using it on July 8th, 2015, there was a problem with the high-definition interface hdmi.

On July 11th, 2015, Konka’s service personnel came to the door for inspection. Mr. Su said that he took apart the back of the TV. After a simple inspection, he did not explain the cause of the failure. As a result, he did not repair it well, so he said that it was damaged by human external force, which was not covered by the warranty. He needed to take the circuit board away. Mr. Su couldn’t figure it out. "This interface is inside the TV. We haven’t removed it. Why is it damaged by external force?" What makes him even more angry is that within 42 days, there were five calls before and after, and there was no reply from the after-sales service. "Let our consumers be chilling!"

Water heaters: Wanhe water heaters have been bought for five years, and the manufacturers have kicked the ball to the sellers.

In April, 2010, Miss Liang bought a Wanhe water heater at Hongpailou Store in oriental home, Chengdu, because she was ready to decorate the new house. Because the new house was not decorated, she didn’t ask the merchant to deliver it. However, in December, 2012, Miss Liang learned that oriental home would close, so she made a special trip to oriental home to inquire about the delivery of water heaters. "At that time, Wanhe’s sales staff asked me to contact Wanhe water heater after sale. I dialed the telephone to communicate the situation on the spot. The other party told me that the information had been recorded in Wanhe’s official delivery system, so I need to install it at any time and call at any time."

In 2015, when Miss Liang’s house was renovated, she contacted after-sales installation. On March 18th, she received an after-sales call from Wanhe Chengdu, saying that it could be installed in the afternoon. However, ten minutes later, another staff member called and told Miss Liang that no record was found in the system and asked her to send the purchase receipt. When Miss Liang did so, Wanhe still claimed that no relevant information was found in the system, so that consumers could find oriental home to solve it themselves.

"However, when communicating with Wanhe by telephone in December 2012, the manufacturer made it clear that there were records in the system and they could contact the delivery and installation at any time." Miss Liang is puzzled. In this regard, Wanhe Electric Company said in its reply that according to the contract, the products should be provided by the "oriental home Store" that sells Wanhe products, and Wanhe Factory does not assume the responsibility of providing products. It is believed that the time span is five years, and the "oriental home Store" has been closed for more than two years, which does not rule out the possibility of losing relevant documents in this store.

Water purifier: Angel called for repair many times during the warranty period, but he didn’t come.

In June, 2014, Mr. Liu from Chengdu bought an Angel water purifier in an electrical mall, with a shelf life of one year. On May 14th, 2015, before the maintenance period, the power light of this Angel water purifier suddenly turned off and no water was produced.

Mr. Liu called for repair, but the maintenance staff kept pushing it from that afternoon to that evening, and then from that evening to May 17, and finally nothing happened on the 21st. So Mr. Liu complained about Angel’s after-sales service again, and the customer service promised to contact him immediately, but nothing happened on the 22nd. It took a whole week, and the maintenance period was about to pass. Mr. Liu contacted the maintenance personnel many times, but he didn’t give a reply or repair, and didn’t even return a phone call.

Coincidentally, Ms. Xu bought the Angel water purifier on October 2 last year, and the water purifier could not discharge water in June this year. Thinking that the warranty period was less than one year, Ms. Xu called Angel several times to ask for the warranty, but Angel kept shirking it. After a month’s delay, the matter has not been answered and solved.

Sichuan Consumer Protection Committee: Complaints about household appliances accounted for the highest proportion in the third quarter.

According to the statistical analysis report of consumer complaint information in the third quarter of 2015 released by Sichuan Consumer Protection Committee, in the third quarter of this year, consumer protection committees at all levels in the province accepted 6,636 consumer complaints, including 1,673 household electronic and electrical complaints, accounting for 25.21% of the total complaints, accounting for the highest proportion.

From the statistical data, the quality of goods and services still ranks first in the total number of complaints and becomes the main complaint of consumers. The focus of consumer complaints is mainly reflected in the quality of audio-visual products and after-sales service. At the same time, compared with the same period in 2014, the proportion of complaints about contracts and after-sales services increased significantly. In the number of consumer complaints in commodity categories, household electronic appliances are still the first.
