This invention provides a method and system for reconstructing the full-band electrochemical impedance spectroscopy (EIS) of lithium-ion batteries. The method includes: performing distributed relaxation time (DRT) analysis on each group of battery EIS samples to obtain DRT spectra; aligning the DRT spectra on the logarithmic time constant axis and performing ensemble statistics, selecting peaks and / or valleys that stably appear under multiple operating conditions based on statistical stability, and mapping them to obtain a set of conditionally invariant characteristic frequencies; selecting characteristic frequency points that satisfy the sampling budget from the set of conditionally invariant characteristic frequencies, and performing sparse EIS measurements on the target battery at these characteristic frequency points to obtain sparse complex impedance inputs; generating a full-band complex impedance sequence based on the sparse complex impedance inputs using an autoregressive reconstruction model; and performing battery state estimation and fault diagnosis based on the full-band complex impedance sequence. This invention significantly improves the continuity of the spectral shape and the generalization ability across operating conditions under sparse sampling conditions, while reducing the full-spectrum testing time and sampling burden.

A light emitting module for a vehicle includes a light source configured to generate light during its operation, a condensing lens located at a front side of the light source in a direction in which light generated by the light source propagates, and configured to change a propagation direction of the input light, and a multi-faceted lens located at a front side of the condensing lens in the direction in which the light generated by the light source propagates, and including a back surface through which the light passing through the condensing lens is input, and a plurality of portions whose front surfaces have different protrusion heights.

This invention discloses an adaptive transmission method for trunked intercom based on wireless local area networks (WLANs), comprising the following steps: collecting link-state and service-state indicators to form a state vector; calculating the carrying window and delay budget using sliding window statistics and exponential weighting, generating a resource profile including congestion and risk levels; layering voice frames and labeling key frames with the latest delivery timestamp; selecting representative terminals for group clustering based on access point identifier, channel, and link quality; and generating transmission parameters by calling an improved BBRv3 under resource profile constraints in the unicast pipeline; prioritizing the transmission of key frame copies, aggregating completion summaries, determining majority completion, and retransmitting missing key frames with targeted compensation and updating completion; switching the distribution mode and performing gray-scale rollback when delay exceeds limits, busy-occupancy surges, or roaming occurs; recording indicator and parameter versions, establishing a template library through scenario fingerprint matching, and storing versioned data. This invention improves the reliability of key voice delivery and reduces the risk of delay jitter and packet loss under congestion and roaming conditions.
