In this paper, the fault diagnosis of battery systems in new energy vehicles is reviewed in detail. Firstly, the common failures of lithium-ion batteries are classified, and the triggering mechanism of battery cell failure is briefly analyzed. Next, the existing fault diagnosis methods are described and classified in detail.
The cooling performance of a battery pack is influenced by several factors. As the power demand for lithium-ion batteries in electric vehicles increases, so do the requirements for the battery thermal management system (BTMS).
The most immediate and observable consequence of a cooling system failure is a rapid increase in the overall temperature of the battery system [110, 111]. This uncontrolled rise in temperature can have several detrimental effects on the battery.
With the increase in vehicle running time and the uncertainty of operating conditions, the vibration, corrosion of components, and expansion of battery gas production can trigger the failure of internal connection components of the battery system, such as loose nuts or welding joints and poor contact [46, 48].
The internal cooling scheme can reduce the maximum internal temperature of the battery and improve the temperature uniformity between batteries. The data shows that the temperature standard deviation decreased by 5 times compared to external cooling at the same pump power of 0.024 W.
The fire hazards related to the battery system of NEVs have aroused the rising attention on battery thermal safety issues . Although the BTMS based on PCM and liquid direct cooling has superior thermal protective performance for battery packs, the cost and the weight limits their application in NEVs.
