Slight variation to vaux idea. I suggest you use a relay to switch them. Bring the new wire from the battery for power and use a relay connected to the interior lights (the coil) to open/close the circuit. Add a fuse to protect your new wire/connection and all should be good.
In summary, in practice, the problems faced by battery fault analysis are mainly online use, sensitive characteristics and accurate detection. To overcome the problem of feature sensitivity, a fault diagnosis method based on a wavelet time-frequency diagram and image feature extraction is proposed in this paper.
A fault diagnosis method for electric vehicle power batteries based on a time-frequency diagram is proposed. First, the original voltage signal is decomposed by improved variational mode decomposition to eliminate the influence of battery inconsistency on battery feature extraction.
Here are some common wiring faults and failures in a Battery Management System: Loose connections – Loose or improperly connected wires can result in intermittent connections, voltage imbalances, and inaccurate readings. This can lead to incorrect charge and discharge control, impacting the overall performance of the battery.
Common battery faults mainly include overvoltage, external short circuits, internal short circuits, sensor faults, etc. [ 6 ]. However, battery fault diagnosis is much more complex because the internal state of the battery is not measurable. In practice, there is only battery voltage, and temperature is a direct response to battery failure.
Therefore, the detection of abnormal changes in battery voltage can be used to detect faults in advance. However, the battery voltage presents nonlinear and time-varying characteristics, so the analysis of the abnormally sharp challenges hidden under the voltage can be challenging.
In the battery system, the BMS plays a significant role in fault diagnosis because it houses all diagnostic subsystems and algorithms. ... Soft internal short circuit (ISCr) in lithium-ion batteries is a latent risk, and it is a primary reason for thermal runaway with blaze and explosion.
