Understanding Gen 2 vs. Gen 3 EV Wall Chargers and Tips for Multiple Charger Installations

Section 1: Understanding the Differences Between Gen 2 and Gen 3 Wall Chargers

When it comes to installing a second wall charger in your garage, there are several things you need to consider. One of the most important is understanding the differences between Gen 2 and Gen 3 chargers. As one user pointed out in a recent conversation, power sharing is not available between these two types of chargers. This means that if you have both a Gen 2 and a Gen 3 charger installed, they will not be able to share power.

Another key difference between these two chargers is their amperage limits. While a Gen 2 charger can go up to 80 amps, a Gen 3 charger is limited to just 48 amps. This means that if you're planning on using separate breakers for each charger, as many users do, you'll need to make sure that you choose the right size breaker for each one.

If you're wondering whether upgrading your Gen 2 charger would be worth it, the answer is probably no. While some users have reported faster charging times with a Gen 3 charger, this likely has more to do with other factors such as battery size and temperature than with the charger itself. Ultimately, unless you're experiencing significant issues with your current setup, it's probably best to stick with what you have.

Do You Really Need Two Wall Chargers?

One question that often arises when considering adding a second wall charger is whether it's really necessary. As one user pointed out in the conversation above, having two chargers may not be as beneficial as you think. In fact, for many households, one charger may be all that's needed.

If you have multiple EVs and high daily mileage commutes, then having two chargers might make sense. However, if you only have one or two cars and don't drive long distances every day, then charging each car on different nights may be sufficient. With an 11kW charger, charge times are fast enough that waiting until the next night to charge shouldn't be a problem.

It's also important to keep in mind that having two chargers pulling 120A could be problematic for a typical home with a 200A service. If you're not sure whether your home can handle the additional load, it's always best to consult with an electrician before proceeding.

Tips for Installing Multiple Wall Chargers

Assuming you've decided that installing multiple wall chargers makes sense for your household, there are several tips you should keep in mind when doing so. First and foremost, make sure that your wiring is up to code and capable of handling the load from multiple chargers. This includes checking wire sizes, distance, shielding, and other factors.

Secondly, be aware of how much power each charger is drawing at any given time. This can help prevent overloading your electrical system and causing damage or safety hazards. Finally, communicate clearly with your family members about who needs to charge their car when and which charger they should use.

By following these tips and taking the time to carefully plan out your installation, you can ensure that your multiple wall chargers work seamlessly together without causing any problems or safety concerns. Whether you're preparing for a CyberTruck or simply looking to streamline your EV charging routine, investing in multiple wall chargers can be a smart move for any EV owner.
