Types of EV Chargers

 

The details of electrical vehicle battery voltage, battery capacity for two wheel, three wheel and four wheel is given below.

Types of vehicles

Battery voltage

Battery capacity ( kwh )

E – Two Wheelers

48 – 72 V

1.2 – 3.3

E – Three Wheelers

48 – 60 V

3.6 – 8

E – Cars ( 1st generation )

72 V

21

E – Cars ( 2nd generation

30 – 80 V

Types of 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.

Types of AC Chargers

Types of DC Chargers

3 Pin

CHAdeMo

Type 1

Combo 2

Type 2

Type 2

Modes 1 to 3

Mode 4

 

Methods of EV 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 EV charging

  • It is also known as dumb charging. 
  • It also permits no communication between Electrical vehicle and Electrical vehicle supply equipment

Mode 2 EV charging

  • The mode 2 charging is used for home charging and it has inbuilt protection and control capability.

Mode 3 & 4 EV charging

  • These types of charger provides separate charger device to supply power to electrical vehicles. 
  • It has improved control systems and it is used for commercial / public charging
