Open up new energy to travel BYD Hanchang test (end)

　　[car home Long-term Test] The content editor of this issue will talk to you about the pure electric vehicle type, which is very important and also a part that you are very concerned about-charging and power consumption. Let’s take a look at whether the performance of Han EV can make our eyes shine and stop being "afraid of electricity".

● Battery/charging information

　　Han EV is equipped with a 76.9kWh battery pack, which supports wall-mounted charging box (household charging pile), household charging connection device (household 220V socket) and DC charging pile. The maximum charging power is 7/1.6/100kW respectively, and the charging time is 13.5/50/1.3h (official data).

● Install charging piles.

　　The installation process of household charging piles is not complicated. First of all, you need to go to the property management office of the community to issue a consent form for installing charging piles. Before, many residential properties refused or evaded or prevented owners from installing charging piles for various reasons. However, after the state issued corresponding policies to encourage residents to build their own charging piles and clearly stipulated that residential properties should give support and help, this situation has been significantly improved.

　　Take Chengdu as an example. After preparing the consent form issued by the property management, the copy of the parking space title certificate/owner’s ID card and the technical specification information of the charging pile, you can submit an application to your power supply bureau. Then the staff of the power supply bureau will contact you for on-site exploration, mainly to find an available electric box nearest to the parking space for placing new meters. It is only the first step to determine the location of installing the new electric meter. It takes a long time to install the electric meter until the power supply bureau sends other staff to install it.

　　After the construction of the power supply bureau is completed, the owner can apply for the installation of charging piles through the "Difenhui+"applet and the "Private Pile Application" entrance in the WeChat WeChat official account of "BYD Auto Sincere Service". It should be noted that BYD only provides charging equipment, cable laying and construction standards, and the "workers" who come to the door for construction are actually BYD’s cooperative installers, and they also run the charging pile installation business of some other new energy brands.

　　For users who don’t know about the installation of charging piles, it is better to report the installation through "private piles" first, and then communicate with the residential property/power supply bureau and make an appointment for the installation time after waiting for the on-site survey by professionals.

　　The installation time of the charging pile depends on the wiring length and whether it needs to be punched. All wires will be covered with plastic pipes to avoid potential safety hazards. The length of the cable provided by the manufacturer is 30 meters, and the extra part needs to be paid by the owner. In addition, the household charging pile provided by BYD is not equipped with a protective box. If you meet a friend who comes to rub the electricity … it is quite embarrassing.

　　The actual maximum charging power of my household charging pile is 6kW. Although the power is not high, it is enough to meet the requirement of having sufficient power when driving to work the next day. Of course, the fast charging speed has to be DC charging pile (fast charging), and its charging power is more than ten times that of household charging pile. In less than 30 minutes, the remaining power can be increased from 30% to 80%, basically leaving you without much mileage worry.

● Power consumption

　　When it comes to the power consumption of pure electric vehicles, the most intuitive feeling of most friends is that it is related to the cruising range. We can’t just look at the amount of electricity consumed by the motor. The performance of the vehicle in many aspects, such as energy recovery and aerodynamic effects, will affect the cruising range. The drag coefficient of Han EV is only 0.233Cd, such as hidden door handle, rim shape and flat chassis will improve the aerodynamics of the vehicle.

　　By the end of March, 2021, the long-distance survey has traveled more than 7,000 kilometers, and the total average power consumption is 18.3kWh/100km, which is lower than the data in the previous period. After the temperature rises gradually, the number of functions such as warm air and seat heating decreases, and the corresponding power consumption is also decreasing.

　　Like traditional fuel vehicles, Han EV will also have higher power consumption when driving on the congested roads that stop and go in urban areas. In addition, outdoor temperature, whether the air conditioner is turned on or not, especially warm air, and seat heating will all have an impact. After the actual test, the editor found that high-speed cruising has a great influence on the performance of vehicle power consumption and the accuracy of cruising range. The power consumption of cruising at 120km/h is more than double that of cruising at 100 km/h. In daily driving, reasonably reducing some speed will still have a positive effect on the improvement of cruising range.

　　　It should be noted that comparing the output power and power consumption at speeds of 120km/h and 100km/h only shows the impact of high-speed cruising on power consumption. Combined with the output power of only about 12kW when cruising at 100km/h, it is unnecessary to test the speed below 100km/h separately. Everyone can rest assured that the endurance of Han EV at 100km/h and below will not bring too much burden to power consumption.

　　When it is necessary to slow down, linear control braking is more conducive to the vehicle to recover energy, but it will not recover capacity when braking with big feet. In addition, operations such as predicting in advance and avoiding sudden acceleration when driving will also make the remaining power "drop" slower.

■ Micro-experience

　　Han EV has a very pleasing function-in-car PM2.5 filter/car air purifier, which is very practical for editors who have rhinitis and are very sensitive to air quality. It can not only purify the air automatically, but also automatically turn it on when the air condition in the car is monitored to be poor.

● Summary

　　After the owner of BYD Han EV has the free installation service of household charging piles, except that he needs to go to the property management office to issue a certificate and the power supply bureau to submit an application, other parts can be safely handed over to the professional team of BYD. The whole installation service process, materials and fees (if exceeding the limit) have strict standards and regulations, and the owner does not have to worry about it at all, which is quite good. In terms of power consumption or endurance, the new car improves the endurance of the whole vehicle by means of energy recovery and wind resistance reduction. Of course, warm air, high-speed cruising above 100km/h and other conditions will have a great impact on power consumption, but fortunately, the cruising range under the working condition of Han EV NEDC exceeds 600km, coupled with high charging efficiency, there is almost no mileage anxiety when using it. OK, that’s all the content of this long-term test. If you have any questions or want to communicate with Han EV, you can click on my editing blog to communicate with me. See you next time.
