AC (Alternating Current): Electricity that changes direction.

DC (Direct Current): Electricity flows 1 direction

kW (Kilowatts): Power

kWh (kilowatt-hours): Energy used

AMP (Ampere): Speed

VOLT (Voltage) Pressure

  • AC: Alternating Current. It is the type of electricity that flows in both directions at regular intervals. For EV drivers, AC chargers are typically slower than DC chargers. , AC current is the kind of power that comes from the power plant to homes and businesses.
  • DC: Direct Current. It is the type of electricity that flows in only one direction. and is the type of power that comes from a battery. DC chargers are faster than AC chargers and can deliver up to 300kW of power. This means that an EV can be charged to full in a matter of minutes.
  • kW: Kilowatt. It is a unit of power that measures the rate at which energy is being transferred. The motor in an EV typically has a power output of several hundred kW. The kW rating of a charger indicates how much power it can deliver.
  • kWh: Kilowatt Hour. It is a unit of energy that measures the amount of power consumed over a period of time. The battery in an EV typically has a capacity of several kWh. The kWh rating of an EV charger indicates how much energy it can deliver in an hour.
  • AMP: Ampere. Unit of measurement that indicates the speed of electric current flow. If you have a battery with a high amp-hour rating, you will need a charger with a high amp rating to charge it quickly.
  • Volt: Voltage. Unit of electrical pressure that measures the force that pushes electrons through a conductor. The voltage of an EV charger determines how much power it can deliver.

Go electric ✌🏼
