How to choose a home EV charger?

With the rising adoption of electric cars, the charging infrastructure is attached to immense importance. Nevertheless, public fast charging imposes intense pressure on the power grid, and it costs more. How to choose a home EV charger?

1. Power supply

Is it possible for you to get 220V power input when you want to install a 7kw EV charger at home? Is it possible for you to apply for 380V power input when you want to install an 11kw or 22kw EV charger at home? In China, some people can apply for three phases, but some cannot. In Russia, some do not have access to electricity while some have. So, make sure the power supply you can get.

2. Charging Speed

1) OBC is the abbreviation for an on-board charger which is used to change the alternate current (AC, from the power grid)into direct current(DC, which can be stored in a battery). Do you have OBC in your car? If not, you cannot choose an AC charger, such as NIO ET7 and ET5. If you have, the power of OBC decides the power of the AC EV charger.

2)  After making sure that there is OBC in your EV, then you also need to consider the battery capacity to make the right decision about the selection of the power of home use EV charger. For example, the power in AC the OBC can accept is 11kw in Tesla Model Y. The battery capacity of the Tesla Model Y Standard Range is 54kwh. In this way, whether you have access to three-phase electricity, the charging time is acceptable. But if you have bought a Rivian R1T Explorer Optional version of which the OBC accepts power in AC is 19.2kw, this is another situation: when using a 7kw charger, it will take 15 hours! So, the better choice is to install an 11kw charger when you are not limited to single-phase electricity, which only takes 9.6 hours to fully charge.

3. With cable or socket type

There is inevitably something like some robbers will cut down charging cables to make profits and the damage to the charging gun results from casual handling of the charging gun or severe weather. That is why here comes the socket type. But you can choose the cable type if the charging gun is not fragile.

For home-use EV chargers, Bluesky has diverse options for you and our three-phase charger can support single-phase input.
