Measure the electrolyte temperature of 10% or more of the battery cells. At least once per year, the quarterly inspection will be augmented as follows: In the case of a lead-antimony battery, measure and record specific gravity and electrolyte temperature of all cells.
To the best of the authors’ knowledge, the contributions of this article are as follows: A complete solution for the whole life cycle online inspection and fault detection of EV batteries is proposed, using the SOC, SOH algorithm and drive method for special scenario application described in the paper.
When the battery shows signs of degradation (decrease in 10% from last test) or is below 90% of the manufacturers rated capacity it is recommended that the batteries be capacity tested annually.
With the continuous development of Evs (electric vehicles) and new energy, smart BESS (battery energy storage system) charging stations came into being, and the EV battery testing technology is particularly important.
Fortunately, new technologies in the world of non-destructive battery testing, such as CT inspection, hold the secret for many manufacturers. By detecting failures early to avoid downstream costs, manufacturers can stay ahead of the curve and ride this surge of upward growth.
While the IEEE Standards reflect the ideal level of maintenance, Eagle Eye recognizes that battery users may have more stringent or less strict requirements and these can be accommodated and if necessary, a custom maintenance procedure can be written.
