Customer ServiceThis study investigates the external short circuit (ESC) fault characteristics of lithium-ion battery experimentally. An experiment platform is established and the ESC tests are implemented on ten 18650-type lithium cells considering different state-of-charges (SOCs). Based on the experiment results, several efforts have been made.
Abstract: External short circuit (ESC) and overcharge are two types of electrical failures in lithium-ion batteries for electric vehicles. Experimental study has been conducted to quickly and accurately diagnose these faults, which is critical to ensure battery safety.
Since the ESC current of the module is much larger than that of the cell, the ESC safety of the cell does not mean the ESC safety of the module, which has been proved in test 1. We take the battery module as the research object to analyze the influencing factors of the magnitude of the ESC current.
The internal resistance of the battery module is affected by the number of series and parallel connections, defined as n / m × r, where r is the internal resistance of a single cell and m is the number of parallel connections. Then the total ESC current Im of the battery module is calculated as shown in Eq. (2).
Due to the different number of series and parallel connections within the module, the maximum voltage of the battery modules is 32.4 V, 48.6 V and 97.2 V, and the capacity is 160 Ah and 50 Ah, respectively. Table 1 shows the basic information of the ESC test samples. Table 1. Specification of the battery modules for ESC test.
In contrast, there are clear distinctions in the ESC of batteries in terms of fault level and short-circuit duration time. It typically occurs at the system level or at the battery pack level with exposed connection terminals.
