They are called chargers, but in fact are only supply units that provide power and some first level diagnostics for your electric or hybrid vehicle. The charger is actually on board the vehicle and regulates the amount of power supplied to the batteries. The main purpose of a charging station is to establish communication with the vehicle and to transfer power to the vehicle while providing proper grounding, shock protection, overload protection and general safety.
There are three charging levels:
- Level 1 – 110/120 Voltsﾠ
- Level I supply units provide charging through a 120 volt, alternating-current (AC) plug. Level 1 charging can be used in a standard 15A duplex receptacle. Level 1 charging equipment does not require the installation of charging equipment but usually requires a dedicated 20 Amp circuit.
- It will come with a cord set you can plug into any household 15A receptacle and the other end is a J1772 connector that plugs into the vehicle.
- Level 1 charging can take up to 20 hours to fully charge a depleted battery depending on the battery bank size. This would be considered a secondary form of vehicle charging. Primary charging should be provided with a Level II supply unit.
- Provides the slowest rate of charging
- Compatible with home outlets and works for all models; could be portable.
- 5 to 8 kilometers per 1 hour of charging
- About 2-30 hours to fully charged.
- Level II charging is the most widely used medium for electric vehicle charging.
- Uses a dedicated circuit that is 208V to 240V and 30A to 100A.
- 12 to 90 kilometers per 1 hour of charging, depending on the model.
- About 2-10 hours to fully charged.
- Residential, MURB (Multi-Unit Residential Buildings),Workplace, Public and Fleet all utilize 30A charging.
- Level III or properly named DCFC (Direct Current Fast Charger) is another form of charging utilizing DC power (direct current) providing much faster charge times.
- Charge times are significantly faster ranging from 15 minutes to 45 minutes.
- Typically, the battery is only charged to approximately 80% of its capacity.
- The remaining 20% can take up to 6 hrs. on a trickle charge to complete.
