The code part of paper "Autoencoder-Enhanced Regularized Prototypical Network for New Energy Vehicle Battery Fault Detection". The problem of class imbalance is effectively solved. Input samples are passed through a neural network to obtain their embeddings or feature representations.
To this end, a combined model-based and data-driven fault diagnosis scheme for lithium-ion batteries is proposed in this article. First, a model-based fault estimation method with sliding mode observer is developed to estimate the voltage, current, and temperature sensor faults.
To cope with restrictions, the fault can be incorporated into a battery state (e.g., short circuit (SC) current, sensor fault) as U 1, S O C, f T , . The fault severity can be directly estimated from the battery state, which leads to the improvement in fault response time and fault estimation accuracy.
To describe the cross-superposition of various faults during lithium-ion battery operation, a new hybrid fault coding method is proposed. This method uses chromosome coding in a genetic algorithm to unify different fault scenarios. The design of the hybrid fault coding is shown in Fig. 2.
Literature review Battery fault diagnosis involves detecting, isolating, and identifying potential faults in lithium battery systems to determine the location, type, and extent of the faults.
When dealing with SC fault, the reference SOC can be calculated using the Coulomb counting method since the input current is known. Due to the depletion effect of SC resistance, the SOC of a faulty battery cell will experience a reduction compared to a normal battery cell.
The resultant abnormality in the intercell contact resistance is defined as battery connection fault, . Such a type of fault can cause an uneven current flow into a cell, leading to a severe cell imbalance in a battery pack and an increase in heat generation . 4.1.3. SC faults
