An electrified powertrain system including a battery pack, electric motor, and a local controller. In response to a connection of the battery pack to an offboard charging station having a station controller, the local controller receives a reported charging limit from and transmits an initial charge request signal to the station controller. The initial charge request signal is a request for charging power or current at the reported charging limit. The vehicle controller also detects a threshold oscillation of the charging limit during an active charging event during which the battery pack recharges. In response to the threshold oscillation during the active charging event, the vehicle controller temporarily reduces the initial charge request to a derated level.
