Zusammenfassung:The disclosure provides an electrified vehicle measurement error compensating charge voltage request. A vehicle charging system includes a charger configured to adjust an output voltage to achieve a voltage request and output a measured output voltage. The vehicle charging system further includes a controller programmed to measure a terminal voltage of a traction battery being charged and receivethe measured output voltage from the charger. The controller is further programmed to output the voltage request as a sum of a full charge voltage and an estimated voltage measurement error between the measured output voltage and the terminal voltage. 本公开提供"电动化车辆测量误差补偿充电电压请求"。一种车辆充电系统包括充电器,所述充电器被配置为调节输出电压以实现电压请求,并且输出测量的输出电压。所述车辆充电系统还包括控制器,所述控制器被编程为测量充电的牵引电池的端电压并且从所述充电器接收所述测量的输出电压。所述控制器被进一步编程为将所述电压请求输出为完全充电电压与所述测量的输出电压和所述端电压之间的估计电压测量误差之和。
