Nasıl are EV şarj istasyonlar set up?
Jun 25, 2023
With the vigorous development of the new energy industry, electric vehicles are becoming more and more common in life. Automakers such as BYD, BMW, and Tesla have all rolled out all-electric vehicles, while hybrid vehicles are more common. In order to be able to easily charge the batteries of these electric vehicles, charging stations must be established. How to set up the charging pile? Let's take a quick look.
An elektrikli araç şarj istasyon esas olarak oluşur üç parçalar% 3a güç kaynağı sistem% 2c şarj cihazı ve izleme sistem.
The şarj cihazı is the core of the entire charging kazık elektrik sistem, olan olan genellikle bölünmüş içine DC şarj grup ve AC şarj grup. The DC şarj yığın, yani, off-board charger, enables fast battery charging. The AC şarj set mainly sağlar the function of slow şarj the vehicle. The output is AC and should be connected to the built-in charger.
A toll monitoring system consforms of one or more workstations or servers, including monitoring workstations, data servers, etc. These computers are connected through a network. The monitoring workstation sağlar an interface for human-computer interaction charging monitoring to realize monitoring and charger data acquisition and query. The data server stores the raw data and statistical analysis data of the entire billing system, and sağlar data services and other application services.
Power sistem standart gereksinimler
1. Güç gereksinimleri
1) Şarj kazık çalışmalıdır at a voltaj of 10 (20) KV.
2) AC şarj edilebilir pil paketler çalışmalıdır at a voltaj of 380 V veya 220 V
3) DC şarj yığın çalışmalıdır at a voltaj 380 V.
2. Güç kalite gereksinimler
1) The voltage deviation of the power supply should be equal to the voltage deviation of 10 (20) kV, and the subsequent three-phase power supply should not exceed the ±7 of the rated voltage. The voltage sapma of a single-phase 220 V supply must not exceed plus 7 percent , {{{}} percent of the the rated voltage.
2) The frequency deviation shall not exceed ±0.2 Hz.
3) The harmonic voltage limit of the utility grid requires that the total harmonic distortion rate of 10(20)kV three-phase voltage is less than 5 percent , while the total harmonic distortion rate of 380V three-phase voltage is less than 4 percent ;
4) Ne zaman koşuyor at maksimum yük, make sure that the power factor of the 1{0 (20) KV side of the transformer is not less than 0.95.
