With the variety of charging cables available in the market, it can be challenging to determine which one is best for your needs.
In this blog, we will explore the differences between 7kW, 11kW, and 22kW charging cables for electric vehicles, particularly the Tesla Model 3 and Model Y.
We will also discuss the differences between single-phase and three-phase charging, the charging capabilities of each cable, and why you might choose a 22kW charger over an 11kW charger based on cost, weight, and charging speed.
Single Phase and Three Phase Charging Cables
When it comes to electric vehicle charging, there are two types of Type 2 charging cables: single-phase and three-phase. A single-phase Type 2 charging cable is designed for single-phase charging and is suitable for charging at a maximum power of 7.4kW.
A three-phase Type 2 charging cable is suitable for both single-phase and three-phase charging and provides a higher charging power output, resulting in faster charging times.
Ed from Juicd Garage does a great job explaining the difference between 7kW, 11kW and 22kW Chargers. Check out his video below:
Charge Times Between 7kW, 11kW, and 22kW Chargers
The main difference between a 7kW, 11kW, and 22kW charger for an electric vehicle is the charging rate.
A 7kW charger will charge the battery at 7 kilowatts per hour, while an 11kW charger will charge the battery at 11 kilowatts per hour, and a 22kW charger will charge the battery at 22 kilowatts per hour.
However, it's important to note that the maximum charging rate depends on the vehicle's onboard charger. The Tesla Model 3 and Model Y, for example, have a maximum AC charging speed of 11kW, so they won't charge any faster using a 22kW charger.
Is It Better to Purchase a 22kW Over an 11kW Charging Cable?
When it comes to charging your electric vehicle, choosing the right charger is crucial. Here are three reasons why you might want to consider a 22kW charger over an 11kW charger:
Cost
While a 22kW charger may have a higher price tag, it can provide more value in the long run. Investing in a 22kW charger provides the flexibility to charge other Tesla Models, such as the Model S and X, which have a maximum AC charging speed of 16.5kW.
Weight
Although a 22kW charger may be slightly heavier due to its larger size and higher power output, the weight difference is usually minimal. The benefits of faster charging may outweigh the minor increase in weight.
Charging speed
A 22kW charger with 32A will charge 22kW over three phases, while an 11kW charger with 16-20A will charge slower over a single phase (compared to a 7kW, 32A charging cable). While this difference may not be significant enough to concern most users, it's worth considering if you have specific charging needs.
When it comes to EV charging cables, understanding the differences between single-phase and three-phase cables is essential. The main difference between 7kW, 11kW, and 22kW chargers is the charging rate, with 22kW chargers being the fastest. However, whether to choose a 22kW or 11kW charger depends on factors such as cost, weight, and charging speed, which may vary based on individual preferences and needs.
