Frequently Asked Questions

What are the various types of electric car charging?
There are three types of electric car charging: 
Level 1 charging:
Level 1 charging is the slowest mode of charging. Level 1 charging is typically done with the charger that comes with the car. The charger plugs into the 110 Volts socket that is at most homes. Level 1 charging is also known as trickle charging and charges the car at about 4 to 5 miles per hour. This means that a car with a 100 mile range will get fully charged in about 24 hours. Level 1 charging is not convenient for apartments, but it can be used in single family homes or in places where cars are parked for a very long time such as the long term parking in airport garages. Level 1 charging uses the J1772 connector and the peak power in Level 1 charging is 1.92KW.

Level 2 charging:Level 2 charging is a very versatile mode of charging and even at its slowest more than three times faster than Level 1 charging. Level 2 charging uses the J1772 connector and it can charge from 6.24KW to 19.2KW depending on the specific charger model and infrastructure available for charging.
The final speed at which the car gets charged is determined by the onboard charger on a vehicle. Thus, even if the external charger has a higher capacity, the charger that is on the vehicle may limit the speed at which the car gets charged.

DC fast charging:DC fast charging is used to rapidly charge the car. There are three standards for DC fast charging – CHAdeMO, CCS and Tesla Supercharger.

CHAdeMO CHAdeMO originated in Japan and is used by Nissan, Mitsubishi and Kia. Cars that support CHAdeMO in US have an additional CHAdeMO charging socket apart from the J1772 charging socket. The CHAdeMO supports a charging rate between 40KW and 60KW.

CCS or Combined Charging SystemThe Combined Charging System is a means of  delivering high-voltage direct current via a special electrical connector derived from the J1772 standard. Thus cars having a CCS socket will support Level 2 charging with a J1772 charger and a DC fast charging with a CCS charger on the same socket itself. The CCS standard now enjoys wide industry support with GM, BMW, Mercedes-Benz, Fiat-Chrysler, Ford, Honda, Volkswagen and others supporting the CCS standard. Current CCS fast chargers are typically as fast as CHAdeMO chargers, but in the future CCS chargers may even deliver 350KW of power.

The CCS coupler has the J1772 port at the top and  dc fast charging is enabled by the two pins at the bottom.

Tesla Supercharger
Tesla has its own proprietary protocol where it can deliver upto 120KW per car through its superchargers.
