Specifically, it includes whether there is a parking space, whether it can access the line of the national grid, whether the community power supply meets the requirements of the charging pile, and whether the installation of the charging pile can get the consent of the community property. If the home meets the installation conditions, the owner needs to prepare the relevant materials. These materials include: car purchase invoice, ID card, vehicle driving license, property consent certificate, etc.
The procedures required to apply for charging piles include the following steps: The applicant needs to fill in the "New energy.Tram charging pile installation application registration form. Provide proof of the use of the parking space. For the purchased parking space, a copy of the purchase invoice, parking contract or agreement should be provided, and the lease term should be more than one year; For rental Spaces, a rental contract is required.
How about the process and cost of applying for the installation of charging piles? Communication with the property In order to obtain the property to issue a certificate of consent for the construction of the charging pile, it is necessary to communicate with the property. If you have a fixed parking space, proof of ownership is required. If there is no fixed parking space, you can negotiate with the property to install charging points in rental or public parking Spaces.
Application for commercial charging pileProcess site audit: When seeking a site for charging station construction, pay attention to understanding the nature of land and ownership of property rights, and promptly go to the local land and resources department for land legality audit, so as to confirm the ownership and use nature of the land for installing charging stations. Work preparation: Confirm the site, scale and quantity of the charging pile construction, and also confirm the budget and procurement of equipment for the construction of the charging station.
1, for short-wave signals, its wavelength is shorter, generally between 100 meters and 10 meters, its frequency range is lower than the medium wave, generally between 3MHZ and 30MHZ. In radio broadcasting are used in three bands, one is long wave, one is medium wave, the other is short wave, such signals are also vulnerable to buildings and other electromagnetic interference in the surrounding space.
2, the AM mode and the FM mode of the car radio are two modes of the radio, of which AM represents the medium wave broadcastFM stands for short wave. In the course of daily use of vehicles, shortwave broadcasting is more common because of its better transmission effect. However, it may be affected when used in remote areas. The car radio is a voice entertainment configuration installed on the vehicle and is one of the most common devices in the car audio and video system.
3, under normal circumstances, most users usually only listen to local radio programs, buy frequency modulation amplitude modulation (AM/FM) two-band radio can be. To listen to long-distance domestic and foreign radio programs, you need to buy a multi-band radio with short wave. Love music, to sound qualityFor high users, should buy FM stereo radio, the advantages and disadvantages of the matching stereo headphones, to reproduce FM stereo broadcast sound effect greatly.
4, FM is frequency modulation. The frequency of the carrier varies with the amplitude of the modulating signal. AM stands for frequency modulation. The amplitude of the carrier varies with the amplitude of the modulated signal. FSK frequency shift keying. It's a digital signal that modulates the frequency of the carrier. ASK refers to amplitude keying. This modulation method is to adjust the amplitude of the sine wave according to the difference of the signal. Amplitude keying can be implemented by multiplier and switching circuit. PSK phase shift keying.
5, FM is the meaning of frequency modulation. China National Radio has: the first program of China National Radio (Voice of China) Medium wave: 63981001161 KHZ FM: 101 MHZ (only for the Beijing area) shortwave: 6030, 7509649800 KHZ.
In the absence of charging piles, the following ways can be used to charge: Solar home charger: Solar home charger is a device that uses solar energy to charge electric vehicles. It canMonitor your home's power needs, optimize solar charging, and return power to the grid. Smart chargers can adjust the charging rate of electric vehicles according to the home's electricity needs, preventing system overload.
When there is no charging pile at home, we can take the following ways to solve the charging problem: When buying a new car, we can ask the 4S shop for a charging pile, or charge in a nearby building or public charging station, but this method is relatively troublesome. Choose to charge in the fixed charging pile outside, it is recommended to buy a longer range of electric vehicles, which can better solve the charging problem.
Such asIf you don't have a charging station, you can also take the following ways to charge: Solar home charger This charger is a collaboration between the American car manufacturer Etrel and Circontrol. It is able to monitor a home's electricity demand, use solar energy to optimize charging, and return excess power to the grid. In addition, the smart charger can also adjust the charging rate of the electric vehicle according to the household electricity demand.
[Pacific Automotive network] The car has no charging pile can be charged, for new energy vehicles, there are usually three solutions when there is no fixed charging pile and the vehicle needs to be charged. The first possibilityTo use flying line charging, followed by the use of public charging piles, and finally the use of charging piles inside the unit. First of all, flying line charging is currently used by many owners who do not have fixed charging piles.
When electric vehicles do not have charging piles, we can adopt three methods to solve the problem. The first method is to use the flying line to charge, the second method is to go to the public charging station to charge, and the third method is to use the charging pile inside the unit to charge. Flying line charging is a common solution for owners who do not have fixed charging piles. In this case, we can charge the vehicle by means of a plugElectricity.
No charging pile can be charged in the following ways: Solar home charger: This charger is jointly developed by American car manufacturers Etrel and Circontrol. It is reported that the device can monitor the household electricity demand, optimize the charging when using solar energy, and feed electricity back to the grid. In addition, in order to prevent system overload, the smart charger can adjust the charging rate of the electric vehicle according to the household electricity demand. The charger is expected to go into service next year.
