The following mainly analyzes the lead-acid battery short circuit caused by excessive charging current, charging voltage of a single battery exceeds 2.4V, internal short-circuit or partial discharge, excessive temperature rise and valve control failure, and summarizes the treatment methods of lead acid battery short circuit as follows:
To ensure these cells to operate in safety and with efficiency is not an easy task [ , , ]. For the past few years, some analysis reports on spontaneous combustion accidents of battery packs from different institutes have shown that the micro-short circuit (MSC) of cells is the “culprit” of the accidents [ , , ].
This usually happens during some-or-other incident, but it can also be the result of human carelessness or malice. Short circuiting a battery deliberately, or accidentally connects the positive and negative battery nodes, forcing them to be the same voltage. The result, as Wikipedia puts it aptly, is a connection with almost no resistance.
When installing a lead-acid battery, insulation measures shall be taken for the tools which are being used. When connecting, connect the electrical appliances other than the battery first, ensure there is no short circuit, and finally connect the battery.
Micro-short circuit (MSC) of a lithium-ion battery cell is a potential safety hazard for battery packs. How to identify the cell with MSC in the latent phase before a thermal runaway becomes a difficult problem to solve. We propose a diagnosis method to detect the MSC according to the remaining charging capacity (RCC) variations between cells.
A quantitative diagnosis method for the micro-short circuit fault of lithium-ion batteries is proposed. The remaining charging capacity is estimated using the charging cell voltage curve transformation. Estimated the leakage current and micro-short circuit resistance with low computational complexity.
