解决方案

48V电气系统优于目前的12V系统，在为风扇、泵、电动助力转向系统和压缩机供电时提供4倍的功率和更高的效率。虽然高压意味着效率更高，但汽车法规要求如使用高于60V的系统时要使用相对昂贵的屏蔽电缆（以便进行电流隔离），因此48V系统可降低成本。在轻度混合动力车辆中使用的48V系统是企业推动汽车电气化发展的第一步，不仅性价比更高，还可减低排放量。 ST的产品种类齐全，包括硅功率MOSFET、保护元件、栅极驱动器和微控制器，符合AEC-Q100和AEC-Q101标准，可构建经济高效的48V车辆设备。

48V启停系统

启动/停止系统自动关闭并重新启动内燃机引擎，缩短空车时间，从而提高燃油经济性，减少二氧化碳排放。对于车辆驾驶在花费大量时间的城市拥堵交通环境而言，这项功能尤其有用。这需要功率电子器件能够在起动期间应对高电流问题，在高温下的引擎开/关循环期间确保可靠性。 ST的解决方案包括硅功率MOSFET、保护元件、栅极驱动器和微控制器，均符合AEC-Q100和AEC-Q101标准。
