[0002] The battery internal resistance and temperature detection device is a device used to measure the internal resistance and temperature of the battery. This device usually consists of two parts: the internal resistance measurement part and the temperature measurement part. The internal resistance measurement part calculates the internal resistance of the battery by applying an AC signal to the battery and then measuring the returned signal. The size of the internal resistance can reflect the health status of the battery, because as the battery ages, its internal resistance will gradually increase. The temperature measurement part usually uses temperature sensors such as thermistors or thermocouples to measure the temperature of the battery. The temperature of the battery has a great influence on its performance and safety. Too high or too low temperature will affect the life and performance of the battery.
