    • Various arrangements for determining a voltage of a voltage source using pre-charging are presented. Such arrangements may include a measurement module which includes an analog to digital converter, a driver, and an interface. The interface may be electrically coupled with the analog to digital converter and the driver. The driver may be configured to output current to charge a capacitor. After a first predefined period of time, the driver may stop outputting current to pre-charge the capacitor. After the driver has stopped pre-charging the capacitor and a second predefined period of time has elapsed, the analog to digital converter may be configured to measure a voltage of the capacitor. Such arrangements may include a capacitor, wherein the capacitor is electrically coupled with the interface of the measurement module.
    • 提出了使用预充电来确定电压源的电压的各种布置。 这种布置可以包括包括模数转换器,驱动器和接口的测量模块。 接口可以与模数转换器和驱动器电耦合。 驱动器可以被配置为输出电流以对电容器充电。 在第一预定义的时间段之后,驱动器可以停止输出电流以对电容器预充电。 在驱动器停止对电容器进行预充电并且第二预定时间段已经过去之后,模数转换器可被配置为测量电容器的电压。 这种布置可以包括电容器,其中电容器与测量模块的接口电耦合。
