Abstract
A system may include a battery and a processor configured to continuously record a voltage and current as a function of time. A time window may be determined based on the current as a function of time. During the time window, an accumulated electric charge may be substantially zero and an accumulated absolute value of the electric charge may substantially equal a stored comparison value. The processor may calculate an energy loss of the battery and a charge loss rate of the battery within the time window. The processor may further determine whether an internal short circuit exists within the battery based on the charge loss rate and a predetermined threshold value. In response to determining that the internal short circuit exists, the processor may generate an indication that the internal short circuit exists.
