This strategy relies on the ability to not only detect a short circuit in its nascent stage, but also on the ability to track its growth so that the severity of the short circuit can be determined and it can be classified based on how imminent the danger is.
Recently, a pulse current based probe was also designed, which would send high amplitude pulse currents to detect short circuits and estimate the short resistance based on the voltage response of the battery .
For a typical battery, current, voltage and temperature sensors measure the following parameters, while also protecting the battery from damage: The current flowing into (when charging) or out of (when discharging) the battery. The pack voltage. The individual cell voltages. The temperature of the cells.
Current sensors are the main source of information for charging and discharging cycle information by reporting the status of battery SOH to the battery management system. They may be located onboard or externally. With the increase of battery capacities in HEVs/EVs, the requirements on higher current ranges are increasing.
Extended Kalman filter (EKF) , , , , Luenberger observer , and other observers have also been deployed to detect short circuits. The percolation of artificial intelligence into the battery domain especially for prognostics is also worth mentioning.
It is known from the literature [45, 57, 89] as well as from our own preliminary tests that an internal short circuit leads to a very inhomogeneous heat distribution. For this reason, the cell temperature field was recorded by numerous temperature sensors (Figure 2).
