Charging stations are the point of power for electric vehicles, ranging in style and charging levels. The main purpose of a charging station is to establish communication with the vehicle and to transfer power to the PEV while providing proper grounding, shock protection, overload protection and general safety.
There are several levels of charging, offering a range in charge time and infrastructure simplicity:
|Charging Level||Voltage & Current||Charging Time||Equipment|
(AC Low Power Slow Charging)
|230VAC & 15Amp||8-10 hours for a full charge||IEC 60309/IEC62196-2 Type 2|
(DC Low Power Fast/AC High Power Charging)
|DC – 48/72V & 200A AC – (up to 43KW)||3-5 hours for a full charge||GB/T 20234.3 DC/AC IEC62196-2 Type 2|
(Fast DC Charger)
|500-1000Vdc & 200A||Less than 1 Hour||CHAdeMO/CCS2/GB/T 20234.3|
Because Level 1 charging does not require the installation of special charging equipment and the equipment is supplied with the vehicle, it is widely regarded as the simplest and most easily accessible charging method for drivers. However, for EV drivers, due to the lengthy charge time, most charging stations are expected to be Level 2. AC Level 1 is appropriate for PHEVs with smaller batteries.
Because of their high-speed charging capability, DC Fast Chargers will primarily be commercial-grade charging, with potential applications at highway rest stops, fueling stations, fleet bases, commercial parking lots, and car dealers.
