Charge Rivian with Tesla Wall Charger: Is it Possible?

Are you a proud new owner of a Rivian R1T or R1S electric truck/SUV? Congratulations! As more electric vehicles hit the roads, charging infrastructure becomes increasingly important. Can Rivian owners use Tesla’s ubiquitous wall connectors to charge their vehicles? Let’s dig in and find out Charge Rivian with Tesla Wall Charger: Is it Possible?

An Introduction to Rivian and Tesla Charging

Rivian vehicles come equipped to utilize Level 2 and DC fast charging based on the North American standard, known as J1772. This differs from Tesla’s proprietary charging connector. However, Rivian does include a J1772 adapter with the vehicle, allowing access to a wide range of third-party chargers, including Tesla wall connectors with the proper additional adapter.

Tesla wall connectors supply up to 48 amps at 240 volts. Using the in-box J1772 adapter along with a Tesla-to-J1772 adapter allows a Rivian to connect and draw up to 40 amps for optimal charging speed. Let’s take a closer look.

Can You Charge a Rivian with a Tesla Wall Connector?

Yes, a Rivian can connect to and charge from a Tesla wall connector by using:

  1. The J1772 adapter included with Rivian vehicles
  2. A third-party adapter that converts the Tesla connector to J1772

This allows the Rivian to establish the required communication protocol (handshake) with the Tesla charger and start a safe charging session.

Many owners have reported success charging their R1T or R1S using Tesla wall connectors in this manner without issue. However, charging speed may be reduced unless properly configured. Let’s take a look at why.

There are two adapters needed to charge a Rivian using a Tesla wall connector:

1. The included Rivian J1772 Adapter

  • Rivian provides a J1772 charging adapter with both the R1T truck and R1S SUV models.
  • This adapter converts Rivian’s charging port to the widely used J1772 connector standard.
  • This adapter alone DOES NOT allow connecting to Tesla chargers, an additional Tesla-to-J1772 adapter is also required as outlined next.

2. A Tesla-to-J1772 Adapter

  • There are a few aftermarket options available, such as the TeslaTap Mini.
  • This adapter converts the Tesla wall connector to a J1772 plug that the Rivian OEM adapter can connect to.
  • Using the Rivian J1772 adapter along with one of these aftermarket Tesla-to-J1772 adapters enables connecting the Rivian for charging.

Charging Speed Comparison of Rivian with Tesla Connectors

The maximum charge rates supported by the platform 3 Rivians (R1T and R1S models) are:

  • Up to 11.5kW on a 48 amp 240V AC supply on a 60A circuit
  • Up to 7.7kW on a 32 amp 240V AC supply on a 40A circuit

In comparison, a Tesla wall connector can supply:

  • Up to 11.5 kW at 48 amps
  • 7.7 kW at 32 amps

So theoretically, a Rivian can charge at full speed from a properly configured 48 amp Tesla wall connector. However, most existing Tesla wall connectors are likely limited to 40 amps rather than the full 48 amps in consideration of typical electrical service capabilities.

At 40 amps, the maximum charging rate for Rivian from a Tesla wall connector would be limited to around 9.6 kW. This is still a decent L2 AC charging speed that will meet most owners’ daily driving needs. But it falls short of the 11.5 kW maximum that is possible on a higher amperage circuit.

The takeaway? While using a Tesla wall connector is possible with Rivian vehicles, pay close attention to the available electrical circuit rating and Tesla wall connector configuration to ensure optimal charging speed.

Safety should always come first when installing or modifying electrical systems. Consult a qualified electrician if unsure of wiring requirements and capacity for the electrical circuit that will power the Tesla wall connector used by your Rivian vehicle.

Most existing Tesla wall connector installations should have enough excess capacity to supply a charging Rivian without wiring upgrades. But careful consideration should be made around:

  • The home’s main electrical panel capacity
  • The size of the circuit breaker powering the wall connector
  • The wall connector’s configured maximum current draw

As a best practice for optimal charge rate in a Rivian, the circuit breaker and wall connector should be rated to supply 48-amps at 240V on 6 gauge copper wire. This requires at least a 60A circuit in most cases. Upgrading may be required if the existing electrical service or Tesla wall connector limits amperage below this level.

Again, please consult a licensed electrician before modifying existing electrical wiring or circuits powering a Tesla wall connector that will be used by a Rivian vehicle.

Setting Charge Current and Limiting with a Tesla Charger

Tesla wall connectors can be configured to limit the maximum current supplied during a charge session. As outlined above, 40-amps are commonly used as a compromise between charge speed and home electrical service capacity.

If charging a non-Tesla vehicle like a Rivian, the wall connector’s charge current should be confirmed and adjusted to the maximum supported level. This ensures the fastest charging times.

Depending on the specific Tesla wall connector model, this can be accomplished by:

  • Using the Tesla mobile app
  • Initiating a manual firmware update procedure
  • Adjusting an internal DIP switch

Reference the installation guide for your specific Tesla wall connector model for detailed steps to configure the charge current. Consider setting amperage to the maximum 48A supply if electrical system capacity allows to enable the quickest Rivian charging time.
