Claim 9:
10. The method of claim 8, wherein determining that the battery module fails, when the first thermal-runaway parameter is greater than the first threshold, the second thermal-runaway parameter is greater than the second threshold, and the difference is less than or equal to the difference threshold comprises:
determining that the battery module fails, when the first temperature is greater than a first temperature-threshold, the second temperature is greater than a second temperature-threshold, and the temperature difference is less than or equal to a temperature difference threshold; or
determining that the battery module fails, when the first combustible-gas-concentration is greater than a first gas-concentration-threshold, the second combustible-gas-concentration is greater than a second gas-concentration-threshold, and the gas concentration difference is less than or equal to a gas-concentration difference threshold; or
determining that the battery module fails, when the first smoke-concentration is greater than a first smoke-concentration-threshold, the second smoke-concentration is greater than a second smoke-concentration-threshold, and the smoke concentration difference is less than or equal to a smoke-concentration difference threshold.
