Can a 7kw charging station connect to 220V household electricity.

Can a 7kw charging station connect to 220V household electricity? The answer is that a 7kw charging station can connect to household 220V electricity. It is worth noting that household 220V cannot be fast charged, after all, it is already not easy for household lines to withstand slow charging of 6-7 kilowatts. The general household electricity meter is 10A (40A), and its current=power/voltage, which is about 7000/220=32A.

What should be noted when using a 220v7kw household car charging station?
 
1、 Site selection before installation of car charging stations
Before installation, it is necessary to consult with the property management of the community to see if the installation of car charging stations is allowed in the community. If installation is allowed, it is still necessary to apply for the installation of car charging stations at the local power bureau; If not allowed, you can find a professional car charging station installation company or local power bureau to coordinate.
 
Also, when choosing the installation location, it is important to be careful not to occupy too many public resources, and to choose some relatively easy to dock locations. If there is an underground parking lot, it is best to install it in the parking lot, and if it is installed outdoors, moisture-proof work needs to be done in advance.
 
2、 Requirements for installation lines of car charging stations
For current household car charging stations, the power is generally around 6000 watts. If calculated based on this power, the current passing through the wire is 27.27A. However, according to the wire selection criteria, the maximum current generally needs to be greater than 30% of the rated current. Therefore, the selection of the wire should generally not be less than 4 square millimeters, and it is recommended to choose copper core multi strand wires. If the wire is chosen too thin, it is easy to cause the wire to heat up during the later charging process, thereby affecting the safety of the entire charging station and vehicle.
 
3、 Electricity bill
If there is no problem connecting the charging cable of the new energy vehicle to household use, but attention should also be paid to electricity bills. The electricity cost for residents is around 60 cents per kilowatt hour, but the electricity consumption for charging new energy vehicles over a long period of time should not be underestimated, especially now that household electricity is charged in a tiered manner. Another issue is charging efficiency. If connected to a household 220V charger, the charging time is a major concern. Firstly, the power of household sockets is not very high, with a maximum of only about 6kw, which is likely to take more than ten hours to fully charge the battery.
 
When installing a charging station, it is necessary to have a solid grounding, because if there is no grounding wire, leakage will occur, which will cause safety problems. Moreover, if the system detects a leakage or poor grounding, it will stop charging and cause a charging fault. Before charging, it is necessary to distinguish between the fast and slow charging interfaces of the vehicle and select the corresponding charging method. And after the charging is completed, it is still necessary to remove the charger in a timely manner to prevent overcharging from damaging the power battery. Try to fully charge the battery at once during the charging process, and do not interrupt the charging process before it is completed. Try to avoid charging in extremely cold conditions during winter, as this can not only affect the charging speed but also easily lead to a decrease in the capacity of the power battery.
