How EV Charges and What are the Different Charging Levels?

July 8, 2022 0 Comments

Electric Vehicle demand is increasing all around the world, even in Australia. Many drivers are excited to do the right thing like saving the environment by using green fuel as well as saving costs down the line. EV buying is costly, which is one of the main reasons several Australians are not buying it. Another reason is they are concerned about finding charging stations on the road. In Australia, three levels of charging points are available for EV charging.

How EV charge?

Home utilities make use of AC fed from the grid domestic socket. Alternating current [AC] means changing direction often while flowing. It can be efficiently transferred across long distances. Direct current or DC is also used for powering devices. It is electricity that is stored in batteries. It travels in a straight line to power the device directly. 

When an electric device is plugged into a socket, it receives AC power. The batteries in your electrical devices store DC, so there is conversion happening within the device. EVs even work the same way in power conversion. Grids power is converted within the car by an onboard converter for storage as DC in the battery that fuels your vehicle.

Different EV charging levels

Type 1 and type 2 stretch charging cable is commonly used to charge EVs, especially at home. There are levels 1, 2, and 3. Level 3 is a supercharger but the crucial thing to remember is that the charging capabilities of each EV differ. Fortunately, the car determines the speed of power acceptance. Therefore EV owners need not be concerned about plugging in a charging port that is capable to deliver more power than the capability of your EV to handle it. The car does not allow the charger to deliver more power than it can handle. 

Level 1 charger 

It is suitable for the domestic outlet of 120V available at home, public stations, and workplaces. Every EV can be charged with a level 1 charger from a standard domestic outlet. Its charging speed is too slow – 3 to 5 miles in an hour. Cars with small batteries less than 25kWh are compatible, but for large batteries type 1 charger is extremely slow for daily charging unless you don’t drive often or drive less distance every day. 

Level 2 charger

The majority of BEV owners prefer a type 2 charger for their daily charging. Install level 2 charging equipment at workplace, home, and even in public locations train stations, plaza malls]. Level 2 charger needs 208 to 240V and has a charging speed of 12 to 80 miles in an hour based on power output and maximum charge rate of the vehicle. The level 2 charging equipment allows EV owners to charge their car 10X faster at home. It means their EV gets fully charged overnight even if the battery was nearly empty when plugged in. 

Level 3 chargers

It is the fastest charger handling 400V to 900V with a charging speed of 3 to 20 miles in a minute. A high voltage supply is necessary for type 3 charging, which only some residential areas have. Level 3 charger and charging is extremely costly than level 1 and 2.
