Therefore, accurately identifying the safety status of the battery pack is of great research significance to improve the battery system's reliability, enhance the safety performance of the whole vehicle, and promote the popularization of electric vehicles. 1.2. Literature review
To this end, the study proposes an intelligent diagnosis method for battery pack connection faults based on multiple correlation analysis and adaptive fusion decision-making.
Literature review The safety status of the battery pack is usually monitored by the Battery Management System (BMS) installed in the electric vehicle. The BMS evaluates the state of the battery pack by using signals such as current, voltage, and temperature collected during the operation of the battery system.
As can be seen in Fig. 2, the connection fault of the battery pack has the following two characteristics: 1. When the fault occurs, the voltage of the faulty single unit is characterized by a gradual deviation from that of the healthy single team.
Experimental results show that the prognostic model can be implemented among various battery packs with satisfactory accuracy and reliability. The mean absolute errors and root mean square errors are less than 2.5% and 3.1%, respectively, under various application occasions. Previousarticlein issue Nextarticlein issue Keywords
