Rivian Warns Against Old Adapters For R2 EV Charging

Rivian issued a warning this week to owners of its new R2 electric vehicle regarding the use of charging adapters. The company stated that older, high-amperage charging adapters may not be compatible with the R2's charging system and could overheat, potentially leading to melting.

This advisory stems from Rivian's decision to maintain a 400-volt architecture for the R2, a choice made to help manage production costs. While this voltage is standard for many EVs, the R2's specific charging implementation can place a higher demand on adapters. The company emphasized that using an incorrect adapter could pose a safety risk and damage charging equipment.

Rivian has not specified which older adapters are problematic but strongly recommends consulting the vehicle's manual or official Rivian charging accessory guides to ensure compatibility. The company is likely to offer or recommend specific adapters that are certified to work safely with the R2's charging infrastructure. Owners are encouraged to verify their adapter's specifications before attempting to charge the R2 to prevent any potential hazards or equipment damage.
