1. A method comprising:
using a signal generator, providing a first test signal to a battery voltage measurement circuit that is coupled to a battery;
using a first analog-to-digital converter (ADC) circuit, receiving a first voltage signal from the battery voltage measurement circuit and providing a first output signal based on the first voltage signal from the battery voltage measurement circuit, wherein the first voltage signal is received by the first ADC circuit from the battery voltage measurement circuit in response to the first test signal: and
using a processor circuit coupled to the first ADC circuit, validating the first ADC circuit based on a correspondence between a characteristic of the first test signal and information about the voltage in the battery voltage measurement circuit in the first output signal;
wherein the processor circuit controls the signal generator to provide the first test signal.
