There are some free public chargers available. Paying stations often set their fees based on the amount of energy that is delivered to the electric vehicle. The pricing of other charges is per minute. The size of the battery, the power of the charger, and the effectiveness of the vehicle's energy supply all affect costs.
The highest rated electric vehicle charger that may be installed at home is 22kW, in contrast to public charging stations that use DC energy. You can't install a 22kW EV charger at home on a single-phase energy supply; instead, you need a three-phase electricity supply.
In addition to requiring EVs that can charge at that rate-the majority, as of this writing, cannot-22kW charging also calls for specialized charging cables. Since most non-premium EVs lack these charging cables, a 22kw charger can only charge an EV at a maximum speed of 7kW.
22 kW of charging can be helpful if you need to charge multiple EVs. You have more possibilities for charging, for instance, if you have many electric cars in your home. The EVs are then guaranteed to be charged more quickly by a 22 kW charger, which facilitates easier "sharing" of the charger.
You might find 22kW three-phase charging helpful if you own more than one electric vehicle. For example, having a faster charging option might be more convenient if you own multiple EVs. In this case, a 22kW would make it easier to share a single charger by enabling you to charge your automobiles more quickly.
It will typically take 4 to 8 hours to fully charge your car using the most popular 7kW charger, which equates to an overnight battery life. You can still charge your automobile with a 3-pin connector if you are unable to install a special home charger.
Although many of the more recent chargers can produce up to 50 amps, experts advise using at least 30 amps.
It depends on a number of factors, including the charging power your charging station offers. In general, the faster the charging procedure, the higher the charging power of both the car and the charging station. As such, the charging speed of a 22 kW wallbox is twice that of an 11 kW wallbox.
