New energy vehicles are now the first target for consumers to buy cars. The government is also relatively supportive of the development of new energy vehicles, and has issued many related policies. For example, consumers can enjoy certain subsidy policies when purchasing new energy vehicles. Among them, consumption Consumers are more concerned about the issue of charging. Many consumers want to install the policy of charging piles. The editor will introduce you to the installation of charging piles today. Let’s take a look!
The charging time of each brand and model of electric vehicles is different, and it needs to be answered from two conveniences, fast charging and slow charging. Fast charging and slow charging are relative concepts. Generally, fast charging is high-power DC charging, which can fill 80% of the battery capacity in half an hour. Slow charging refers to AC charging, and the charging process takes 6 hours to 8 hours. The charging speed of electric vehicles is closely related to the power of the charger, the charging characteristics of the battery and the temperature. At the current level of battery technology, even fast charging takes 30 minutes to charge to 80% of the battery capacity. After exceeding 80%, in order to protect the battery, the charging current must be reduced, and the charging time to 100% will be longer.
Introduction to Electric Vehicle Charging Pile Installation: Introduction
1. After the user signs the car purchase intention agreement with the car manufacturer or 4S shop, go through the confirmation procedures for the car purchase charging conditions. The materials to be provided at this time include: 1) the car purchase intention agreement; 2) the applicant’s certificate; 3) fixed parking space property rights or use Proof of right; 4) Application for installing electric vehicle charging equipment in the parking space (approved by the property stamp); 5) Floor plan of the parking space (garage) (or on-site environment photos). 2. After accepting the user’s application, the auto manufacturer or 4S shop will verify the authenticity and completeness of the user’s information, and then go to the site with the power supply company to conduct electricity and construction feasibility surveys according to the agreed survey time. 3. The power supply company is responsible for confirming the user’s power supply conditions and completing the preparation of the “Preliminary Feasibility Plan for the Electricity Use of Self-use Charging Facilities”. 4. The auto manufacturer or 4S shop is responsible for confirming the construction feasibility of the charging facility, and together with the power supply company, issue the “Confirmation Letter of Charging Conditions for the Purchase of New Energy Passenger Cars” within 7 working days.
It should be noted that it is difficult for the neighborhood committee, property management company and fire department to coordinate. Their questions focused on several aspects: the charging voltage is higher than that of residential electricity, and the current is stronger. Will it have an impact on the electricity consumption of residents in the community and affect the normal life of residents? In fact, no, the charging pile avoids some hidden dangers at the beginning of the design. The property department is worried about inconvenient management, and the fire department is afraid of accidents.
If the early coordination problem can be solved smoothly, then the installation of the charging pile is basically 80% completed. If the 4S store is free to install, then you don’t have to pay for it. If it is installed at your own expense, the costs involved mainly come from three aspects: First , the power distribution room needs to be re-distributed, and the DC charging pile is generally 380 volts. Such a high voltage must be powered separately, that is, an additional switch is installed. This part involves Fees are subject to actual circumstances. Second, the power company pulls the wire from the switch to the charging pile for about 200 meters, and the construction cost and the cost of the hardware facilities of the charging pile are borne by the power company. It also pays management fees to the property management company, depending on the situation of each community.
After the construction plan is determined, it is time for the installation and construction. Depending on the conditions of each community and the location of the garage, the construction time is also different. Some only take 2 hours to complete, and some may take a whole day to complete the construction. In this step, some owners like to stare at the site. My experience is that it is really unnecessary. Unless the workers are particularly unreliable, or the owner himself has certain technical knowledge, the owner is also thankless at the construction site. In this step, what the owner has to do is to first arrive at the site and communicate with the property, realize the connection between the property and the workers, check the cables used by the workers, whether the labels and quality of the cables meet the requirements, and write down the numbers on the cables. After the construction is completed, drive the electric car to the site to actually check whether the charging pile can be used normally, then visually measure the number of meters under construction, check the number on the cable, and compare the cable usage with the visual distance. If there is a big difference, you can pay the installation fee.
