Types of EV Charger
- There are two types of chargers : AC Charger and DC Chargers
- The capacity of the AC chargers from 2 kW to 22 kW and that of DC charger is from 2 kW to 200 kW + DC.

Methods of Charging
- The supply to battery pack is done by direct current.
- The AC supply is first converted in to DC in order to supply to battery.
- In the case of AC Electrical vehicle supply equipment ( EVSE ), the AC power is given to the on-board charger of the Electrical Vehicle which converts it to DC.
- Similarly, DC Electrical vehicle supply equipment ( EVSE ) supply DC Power directly to the battery, bypassing onboard charger.
Mode 1 Charging
- It is also known as dumb charging.
- It also permits no communication between Electrical vehicle and Electrical vehicle supply equipment
Mode 2 Charging
- The mode 2 charging is used for home charging and it has inbuilt protection and control capability.
Mode 3 & 4 Charging
- These types of chargers provide separate charger device to supply power to electrical vehicles.
- It has improved control systems and it is used for commercial / public charging.
