Πώς είναι EV φόρτιση σταθμοί set up?

Με το δυναμική ανάπτυξη του του νέου ενέργειας βιομηχανίας, ηλεκτρικά οχήματα γίνονται περισσότερα και περισσότερα κοινά σε ζωή. αυτοκινητοβιομηχανίες τέτοια όπως BYD, BMW, και Tesla έχουν όλα rolled out όλα-ηλεκτρικά οχήματα, ενώ υβριδικά οχήματα είναι περισσότερα κοινά. In order to be able to easy charge the batteries of these electric vehicles, charging stations must be established. How to set up the charging pile? Let's take a quick Κοίτα.
An electric vehicle charging station is κυρίως compose of three parts: power supply system, charger and monitoring system.
This power supply system κυρίως supplies power to the charger, mainly composed of primary equipment (switches, transformers, switching circuits, etc.) και δευτερεύον εξοπλισμός (συμπεριλαμβανομένης ανίχνευση, προστασία, έλεγχος εξοπλισμός, κ.λπ.) , and is specially equipped with active filtering equipment to eliminate harmonics and stabilize the power grid.
The charger is the core of the entire charging pile electrical system, which is usually divided into DC charging group and AC charging group. The DC charging stack, i.e., off-board charger, enables fast battery charging. The AC charging set mainly provides the function of slowly charging the vehicle. The output is AC and must be connected to the built-in charger.
A toll monitoring system αποτελείται of one or more workstations or servers, include monitoring workstations, data servers, etc. These computers are connected through a network. The monitoring workstation provides 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 provides data services and other application services.
Next, we will focus on power systems and chargers (AC charging stack and DC charging stack).
Power system standard requirements
1. ισχύς απαιτήσεις
1) The φόρτιση σωρός πρέπει λειτουργία at a τάση από 10 (20) KV.
2) AC επαναφορτιζόμενη μπαταρία πακέτα πρέπει λειτουργία at a τάση από 380 V ή 220 V
3) The DC φόρτιση stack should operate at a voltage of 380 V.
2. Ισχύς ποιότητα απαιτήσεις
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 deviation of a single-phase 220 V supply must not exceed plus 7 percent , -10 percent of the rated voltage.
2) Η συχνότητα απόκλιση πρέπει δεν υπερβαίνει ±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) Πότε τρέξιμο at μέγιστο φορτίο, make sure that the power factor of the 10 (20) KV side of the transformer is not less than 0.95.
