Hello, I am studying the design of DC fast chargers. I learned some information about their varieties and the approximate principle of operation (Vienna Rect. - LLC DC/DC - Output). Usually, after Vienna Rectifier, you can get a maximum voltage of about 840VDC, and then lower it to the...

Hi, I am conducting a study on the subject of: charging with alternating current compared to charging with direct current. Now I am studying the issue of placing charging stations in the parking lots of shopping centers. The time spent in the shopping center is 2 - 3 hours. Which option for...

Hi! Is there any protection from AC voltage on the control pilot line? Or it can not happen?

pilot and neutral in the charging cable, then the EVSE will drive about 12mA around the neutral-earth loop. That certainly is a pure DC leakage greater than 6mA, but whether it is enough to actually cause trouble is debatable. Thanks for the information! I found a good solution for...

miimura, Yes, right. My switch responds to AC leakage (30 mA). The article states about DC leakage (6 mA), which can occur if the signal lines (5 V / 12 V DC) are damaged, the leakage of which can lead to incorrect operation of the controller. As far as I understand, this requirement applies to...

Hi! I found an article that talks about changing the requirements for charging stations. In particular, he talks about the DC fault current monitoring. EVSE RCD protection and the 18th Edition I'm a little confused about all this. This protection is needed only for those stations that have...

UMC cut open - Tesla Model S UMC cut open and modified to J1772

You are best! Thank you so much:)

In the High Powered wall charger, such a miniature contactor:

Good day! Does anyone have pictures of the disassembled mobile connector? I want to know about his insides, and is there a contactor in it? If so, which one? Or somehow his principle of work is arranged differently? If anyone knows - tell me) Thank you in advance for your answers!
