Types of EV Chargers

EV Battery Voltage & Battery Capacity

  • In this article, two wheelers, three wheelers and four wheelers battery voltage and battery capacity, types of EV Charger and methods of charging is given. 
  • 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 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.

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 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.
