3 levels of EV charging-explained in depth

3 levels of EV charging

If you have an Electric Vehicle (EV) and you are very much concerned about the battery and charger. Here in this article, you get to know all about 3 levels of EV charging. 

3 levels of EV charging-explained in depth

What is the Electric Vehicle (EV)?

EV functions on an electric motor rather than an internal combustion engine (ICE) like any other vehicles. Electric Motor runs using the power stored in the batteries. When the word batteries come, charging or charger word hits into our mind, just like our mobile phone’s battery.

 EVs are popularly known for their eco-friendly, quiet and speed features.

Electric Vehicles doesn’t have ICEs instead electrical energy is stored in a storage battery or ultracapacitor, converted from chemical energy in a fuel cell or converted from mechanical energy in a flywheel.

The electric energy is helpful in the functioning of the electric motor than passes onto the wheels.

3 levels of EV charging

To any battery operated vehicles charging is must and important part of an EV. The battery needs to be charged when the battery discharges.

If you see, we require power to charge a mid seized EV is the same as you put an electric stove which connected to + 40A, 240VAC circuit developing around up to 9.6kW.

Most mid-sized EVs carry a 6.6kW onboard charger designed for a 4- to a 5-hour charge. (6.6kW is derived by multiplying 220V by 30A.)

But these chargers are limited by costs, size, and thermal issues. These are with three-phase AC power in most European homes and onboard chargers can be made with a two-phase system.

According to battery university, Renault provides the compact-onboard chargers and it also has a smaller two-phase system. It offers the onboard charges that range from 3-43kW.

There are 3 categories of charging

  • level 1-1.5kW typical
  • Level 2-7kW typical
  • Level 3- 50kW typical (Tesla V2 stations charge at 120kW)
  • Extra Fast Charge: 150kW; up to 400kW (Tesla V3 stations charge at 250kW)

Level 1-1.5kW typical

This type of charger we used as the regular household outlet of 115VAC, 15A. Takes 7 to 30 hours to charge for 1.5 kW. It works for 12kWh not exceeding.

It is suitable for overnight charging for EVs such as e-bikes, scooters, electric wheelchairs, and PHEVs.

EV driving range per minute charges 130m.

Level 2- 7kW typical

Suitable for Wall-mount; 230VAC, 30A two pole, charges a mid-sized EV in 4 to 5 hours.

Chargeable at home and public charging stations for EVs. It produces about 7kW to feed the 6.6kW onboard EV charger.

EV driving range per minute charges 670m. 

3 levels of EV charging

Level 3- 50kW typical (Tesla V2 stations charge at 120kW)

This includes DC Fast chargers 400-600VDC, up to 300A; ultra-fast charging by bypassing the onboard charger and feeding the power directly to the battery.

It delivers the power 50 kW of power that can go up to 120 kW to fill a Li-ion battery to 80 percent in 30 minutes.

EV driving range per minute charge at 50kW: 4.6km.

Extra Fast Charge- 150kW; up to 400kW (Tesla V3 stations charge at 250kW)

This charges a high amount to charge an EV as it is 400kW power equal to 16 households.

EV range per minute charge at 400kW – 37km.
