Detecting and mitigating charge signal oscillations during off-vehicle charging event

The invention relates to detecting and mitigating charging signal oscillations during an off-vehicle charging event. An electrified powertrain system includes a battery pack, an electric motor, and a local controller. In response to a connection of the battery pack to an off-board charging station having a station controller, the local controller receives a reported charging limit from the station controller and transmits an initial charging request signal to the station controller. The initial charging 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 is recharged. In response to the threshold oscillation, the vehicle controller temporarily reduces the initial charging request to a derating level during the active charging event. 本发明涉及在车外充电事件期间检测并缓解充电信号振荡。电气化动力总成系统包括电池组、电动马达和本地控制器。响应于电池组到具有站控制器的车外充电站的连接，本地控制器从站控制器接收所报告的充电极限并将初始
