It's worth noting that owners of earlier Lucid Air models (2022-2024) with the Version 1 mobile charger will need to purchase the new Version 2 charger to use the Range Exchange system.

How It Works

Using the Range Exchange system is straightforward:

1. Plug the Range Exchange adapter into the Lucid Air's charge port
2. Connect the other end to the receiving vehicle's charge port
3. Initiate the charging process from the Lucid Air's center display
4. Set a minimum state of charge for the Lucid Air to prevent over-discharging

Real-World Testing

To test the Range Exchange system, we connected a Lucid Air Grand Touring to a Chevrolet Equinox EV. Here's what we found:

• The system delivered a consistent 9 kW of power
• Over a 2-hour charging session, 19 kWh was transferred
• The Equinox EV's state of charge increased by 18-19%
• Estimated range increased by 60 miles

These results demonstrate that the Range Exchange system is capable of delivering its full rated power, making it an effective tool for assisting stranded EVs or topping up a friend's battery.

Practical Applications

While the ability to charge other EVs is impressive, it's important to consider the practical applications of this technology. Most EV owners who run out of charge are likely to be within a few miles of their destination or a charging station. In these cases, a quick 20-30 minute charge using the Range Exchange system could provide enough power to reach the intended destination.

For example, in just 30 minutes, the system could deliver between 10 and 18 miles of range, depending on the efficiency of the receiving vehicle. This could be a lifesaver for someone who has miscalculated their remaining range.

Comparison to Other Vehicle-to-Vehicle Charging Solutions

While Lucid's Range Exchange system is innovative, it's not the only vehicle-to-vehicle charging solution on the market. Here are some alternatives:

Ford F-150 Lightning Pro Power Onboard

The Ford F-150 Lightning offers a 240V outlet in the bed, which can be used to charge other EVs. This system uses the truck's battery as a power source and requires a separate mobile charger.

Vehicle-to-Load (V2L) Adapters

Some EVs, like certain Hyundai and Kia models, offer V2L capability. These systems typically provide a standard outlet that can be used with a mobile charger. However, they generally charge at a slower rate compared to Lucid's Range Exchange system.
