The invention relates to operator-selected operation of an electric propulsion system with reconfigurable series/parallel voltage sources. An electric propulsion system includes a rotating electric machine having an output member, a rechargeable energy storage system ("RESS") connected to the electric machine, a user interface device, and a controller. The RESS includes a plurality of battery modules and a switching circuit configured to connect the battery modules as a selected battery configuration in a parallel connection ("P-connection") configuration or a series connection ("S-connection") configuration in response to an electronic switching control signal. The user interface device receives a driving mode signal indicative of an operator request for a desired driving mode of the electric propulsion system. A controller programmed with a mode-specific electrical loss associated with a desired driving mode establishes a selected battery configuration in response to the driving mode signal and presents a driving mode recommendation via a user interface device when the loss associated with the desired driving mode exceeds a calibrated loss threshold.

    本发明涉及一种具有可重新配置的串联/并联电压源的电力推进系统的操作者选择的操作。电力推进系统包括具有输出构件的旋转电机、连接到电机的可再充式能量存储系统(“RESS”)、用户界面装置和控制器。RESS包括多个蓄电池模块和开关电路,开关电路被配置成响应于电子开关控制信号按并联连接(“P‑连接”)配置或串联连接(“S‑连接”)配置作为选定蓄电池配置连接蓄电池模块。用户界面装置接收指示电力推进系统的所期望驾驶模式的操作者请求的驾驶模式信号。编程有与所期望驾驶模式相关联的特定于模式的电气损耗的控制器响应于驾驶模式信号建立选定蓄电池配置,并且当与所期望驾驶模式相关联的损耗超过经校准损耗阈值时经由用户界面装置呈现驾驶模式推荐。
