Electric vehicle charging levels & speeds in strata car parks and commercial settings.

When it comes to EV charging speeds you need to understand two concepts; power supply and EV charging levels.

Power Supply

The charging speed of your EV charger is determined by the power supply you have available to the charger. This power supply will either be what is called single phase or three phase power supply. 

Single phase will typically get you around 7.4 kilowatts (kw) power supply which is around 40km of range per hour of charging. 

Three phase will get you around 22kW power supply which is around 120km of range per hour of charging. Around three times faster than single phase.

For charging in existing buildings or commercial settings single phase or three phase can be used. Most buildings have three phase power coming into the building however giving three phase power to each resident’s individual EV charging stations would use too much of the building’s power supply so wouldn’t be feasible. Generally, larger buildings choose to supply residents with single phase power in their individual car spaces which is more than adequate for the average persons driving and charging habits. If they want a faster charging option available in the building they may provide three phase power to dedicated EV charging spaces (generally visitor car spaces allocated for EV charging).

EV charging levels

Once you understand the power supply you have available you can work out the charging speed you can get with your charger. 

There are three levels of charging; Level 1, Level 2 and Level 3. The higher the level of charging, the faster the charging process. 

Level 1
Level 1 is when you are charging from a General Power Outlet (power point). It is the slowest of all the charging speeds. This can be a good entry level place for strata car parks to start if residents are resistant to EV charging infrastructure. It still allows residents to have access to some sort of power for EV charging in their individual car space and can also be utilised by non EV residents for their general usage (eg. vacuuming).

Level 2
Level 2 is the most commonly used level of charging for daily EV charging. The charging speed and range you get depend on whether you have a single phase or three phase power supply. For strata car parks we generally only install single phase capabilities to each individual residents car space as three phase uses too much of the building’s power supply.

Level 3
Level 3 is the fastest level of charging available. Unlike Level 1 & 2 charging which uses alternating current (AC), level 3 charging uses direct current (DC). This is why you will see the chargers used in Level 3 being called DC chargers. These chargers are the most expensive of all the chargers and are not generally used in residential strata settings due to their cost and power requirements.

What range do I get from each charging level?

The charging level dictates the range you will get per hour of charging. Below is a table that summarises the charging speeds for all levels.
