Rivian Portable Charger is sensitive to grounding and can be finicky when it comes to power quality. The light on the charger frequently goes red on 120v and 240v, even if other EVSEs have no issue. To solve this problem, one should consider changing out the breaker for the 240v circuit to a ground-fault protected breaker. This will help if you can’t improve the grounding in your home itself. However, GFCI breakers are notorious for causing problems with EVSEs. According to NEC 406.3(d)(3)(c), if you don’t have good grounding, you use GFCI outlets or circuits for added protection. If you’re tripping the circuit interruptor due to ground fault, then there’s something wrong with your equipment itself. It is recommended that one install a second ground rod and bond them with a continuous #4 copper wire straight to the panel (And then actually run a ground wire from the panel to your EVSE if it’s not wired properly already). Better grounding will almost always improve outcomes.

It is also important to note that all EVSEs are required to have ground fault protection, even mobile ones. It is the cause of many of the errors people are seeing. The unit is detecting a ground fault, or falsing off a redundant GFCI. To avoid these problems, it is better to have a hard wired EVSE. It is also recommended that one buy a second EVSE and hardwire it at home, as plugging and unplugging will get old fast and it's not great for the receptacle. Understanding potential problems such as the ones discussed in this thread can be very helpful.

It is also important to note that the Rivian Portable Charger has a built-in ground fault protection system. This means that it will shut off if it detects a ground fault. It is recommended that one check the ground connection of their EVSE and make sure it is properly grounded. If it isn’t, then one should consider having an electrician come out and fix the problem.

In addition, it is important to understand how the Rivian Portable Charger works in order to get the most out of it. The charger uses a combination of current sensing and voltage sensing to determine when to start charging and when to stop. It also has a built-in timer so that it will automatically turn off after a certain amount of time. This helps prevent overcharging and ensures that the battery is not damaged by excessive charging.

Finally, it is important to remember that the Rivian Portable Charger is sensitive to grounding and power quality issues. It is important to take steps to ensure that your home’s electrical system is up to code and properly grounded. If you are having trouble with your charger, then it may be worth considering changing out the breaker for the 240v circuit or installing a second ground rod. Understanding potential problems and taking steps to address them can help ensure that your charger works properly and efficiently.

Is the Rivian Portable Charger sensitive to grounding?

Yes, the Rivian Portable Charger is very finicky when it comes to power quality and grounding. The light on the charger frequently goes red on 120v and 240v, even when other EVSEs have no issue. If you’re having ground fault issues, the issue lies with the EVSE itself and poor quality manufacturing. Consider changing out the breaker for the 240v circuit to a ground-fault protected breaker or adding a second ground rod and bonding them with a continuous #4 copper wire straight to the panel.

Does the Rivian Portable Charger have built in ground fault protection?

Yes, all EVSEs are required to have ground fault protection, including the portable charger that comes with the truck. The NEC was amended to require a GFCI breakers on 14-50 outlets that are used for EV charging.

What is the best way to avoid nuisance tripping of GFCI breakers?

Installing a hard-wired EVSE at home is recommended as it will help avoid nuisance tripping of GFCI breakers. Choose a model that is power-share ready so that one is prepared for the next EV, and you do not have to run a 2nd dedicated line. It is also recommended to leave the mobile charger in your vehicle for when it is needed on the road.

What is the best way to ensure proper grounding?

Proper grounding is essential for safe and reliable charging. It is recommended to install a dedicated ground rod at least 8 feet away from any other metal objects, such as water pipes or gas lines. Bond the ground rod to the panel with a continuous #4 copper wire. Make sure that the ground rod is connected to the panel in a manner that will not be affected by corrosion or other environmental factors.

Is it necessary to use a surge protector when charging with the Rivian Portable Charger?

Yes, it is highly recommended to use a surge protector when charging with the Rivian Portable Charger. Surge protectors are designed to protect your EVSE from power spikes and surges that can damage your charger and potentially cause fires. Look for surge protectors that have been tested and certified by Underwriters Laboratories (UL).
