If one station is in use, it gets the full 30 amps of available power. If another vehicle plugs into another charger on that circuit, each charging stations would receive 15 amps of power. Using our formula, we can see how this affects the amount of kW delivered to the EV:
Suppose you have an EV with a 7.2 kW rating. This means if you use the charging station from Example 1, your EV can accept the full 7.2 kW of power that the charging station can supply. However, if you plug this same EV into the charging station from Example 2, it can still only accept a maximum of 7.2 kW of power.
These stations come with various amperage ratings to meet the power needs of different EVs. For instance, the Blink Series 7 Level 2 Charging Station can deliver up to 80 amps of power to your EV.
When deciding how many amps your home charging station should have, consider your average miles driven per day, how often you would be able to charge at home, and your vehicle’s charging rate. For example, using a 16-amp charging station for eight hours would provide you 95 miles of range each time you charge.
EV charging stations, also known as Electric Vehicle Supply Equipment ( EVSE), are the lifelines of electric vehicles. They’re the places where EV possessors recharge their vehicle’s batteries. Understanding how important power these stations need is pivotal for icing effective and accessible charging.
After one hour of charging, your EV will have an added 7.2 kilowatt hours (kWh) of energy. To calculate how long it will take to charge your entire battery based on your EV charging station, take the vehicle’s battery capacity, in kWh, and divide that by the charging station’s kW output.
