Charging Your Tesla Model 3 and Rivian R1S: Tips & Solutions for Multi-EV Homeowners

Title: Model 3 and Rivian in the Same Garage: Charging Solutions for Electric Vehicle Owners

Exploring Different Charging Options
As electric vehicles (EVs) become more popular, many households find themselves owning multiple EVs from different manufacturers. One such example is having a Tesla Model 3 and a Rivian R1S in the same garage. In this situation, charging both vehicles efficiently can be a challenge due to their different charging connectors – Tesla uses its proprietary connector while Rivian utilizes the J1772 standard.
There are several options to consider when it comes to charging these two vehicles at home:

1. Install a Rivian-specific or third-party charger that can charge both vehicles.
2. Add a second Tesla charger (black/J1172 version) and link them together for management.
3. Replace the current Tesla charger with a black/J1172 Tesla version with a longer cable and use a Tesla adapter when charging the Model 3.
4. Replace the current Tesla charger with a white/Tesla version with a longer cable and use a third-party adapter when charging the Rivian.
Each of these solutions has its pros and cons, but ultimately, your choice will depend on factors such as cost, convenience, and available space in your garage.

Maximizing Efficiency and Flexibility
For those who want to charge both vehicles overnight or take advantage of off-peak electricity rates, adding a second Tesla charger (option 2) might be the best solution. This allows you to charge both cars simultaneously without needing adapters or extension cords.
Another option worth considering is creating a "Frankenstein" setup using your existing Tesla Gen X charger, combined with a J1772 adapter and extender cable. While this may seem complicated, it should work well and provide enough distance between the two vehicles for convenient charging. However, if you choose this route, make sure each component is rated correctly for the desired amperage.
If you prefer a simpler solution, replacing your Tesla wall charger with a NEMA 14-50 plug and using the included J-1772 cord that comes with the Rivian might be ideal (option 3). You can also purchase a Tesla mobile adapter and NEMA 14-50 adapter to switch between charging the two vehicles as needed. This setup is flexible, cost-effective, and relatively easy to implement.

Choosing the Right Equipment for Your Needs
When selecting equipment for charging multiple EVs in one garage, it's essential to consider factors such as amperage, compatibility, and ease of use. For example, if you require more than 40 amps for fast charging, a single J1172 charger may be best for the Rivian, while using an adapter to charge the Tesla.
Upgrading to a 60-amp circuit (breaker and wiring) could provide a higher amped charge for both vehicles, ensuring faster charging times when you're on the run. In this case, products like the ChargePoint Home Flex offer reliability and functionality at an affordable price point.
In conclusion, owning multiple electric vehicles from different manufacturers doesn't have to be a headache when it comes to charging solutions. By carefully considering your needs and available options, you can create an efficient and convenient home charging setup for both your Tesla Model 3 and Rivian R1S.
