    摘要: Disclosed is a method for detecting an internal short of a battery, which may include: acquiring first charge state information related to a charge state of the battery; detecting a first reference time point when the first charge state information satisfies a reference condition; acquiring second charge state information related to the charge state of the battery; detecting a second reference time point when the second charge state information satisfies a reference condition; and detecting an internal short of the battery based on a difference between a charge amount from the first reference time point to the second reference time point and a discharge amount from the first reference time point to the second reference time point.

    摘要: The invention relates to a method for evaluating a state of health (SOH) of an electric battery of an electric vehicle, said method comprising a step of:
    - performing a given number (m) of tests on the electric battery, each giving results,
    - associating each result to a state of the battery, a given number (N) of states of the battery being possible,
    - estimating a probability of each state of the battery on the basis of a Bayesian calculation, and
    - estimating the SOH in function of the probability of each state and of the results of the tests, called estimated SOH.
