In China, since the home is still only at the beginning, I am looking forward to what will happen in the future. Write the case of the United States, most of the blog posts directly from the "NECA 413: National Electrical Installation StandardTM for EVSE", IWC meeting materials opened in March 2011.
This article refers to the address: http://
The National Electrical Contractors Association is a US electrical company that organizes a lot of UL's electrical safety aspects. The initial control was from NECA.
1. Portable charging (Level 1)
At this point, in general, the charging device follows the car, using a universal plug. In the UL regulations, the Level1 charger has three basic functions: leakage protection, insulation protection and ground detection. It is not discussed here. Power rating, the US voltage is designed to be 125V (Rated), 15A or 20A maximum current.
As shown in the figure, in the wiring process, if you want to DIY, just separate the line corresponding to the plug of the garage and pass the air switch in the power distribution box. As shown in the figure below, you need to select the cable of the appropriate size to charge with a certain current. In the figure below, GFCI (which is already in EVSE) is configured on the socket to prevent some people from using "Mode 1" charging, but it is forbidden in this US.
2. Faster charging (Level 2)
Because Level1 is slower, there is Level2. Because the socket may be misplaced at work, it must be hardwired together (the latest NECA allows the socket to be used). At this time, the voltage is substantially 240V, which is similar to that in China. Therefore, the EVSE from the United States does not have to worry about being damaged by high voltage transients in China, and its own reference value is 20V higher.
The current Level 2 is generally 16A or 32A, and the 80A defined by SAE currently seems to be out of reach. Be sure to choose the right line and the correct connection switch, pay attention to the above connection method.
3.Level 3
What is embarrassing is that the United States generally does not provide three-phase power to the home, but this Level3 has some overlap with DC charging in terms of power, and the use of three-phase rectification on electric vehicles is not a default option, so it is temporarily ignored. It.
I was on vacation today, I was going to the hospital to help with the appointment. The 3rd hospital in Shanghai is really very **. It will not be built for more than 70 days. Tomorrow, I have to go to the hospital with a cigarette to visit a hospital. I hope everything will go smoothly.
