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:
ACTUAL SHORT CIRCUIT CURRENTS FOR VRLA BATTERIES “shorted” lead acid battery has the capability of delivering an extremely high current, 100 to 1000 times the typical discharge current used in most applications. Electrical systems using batteries must be properly protected to avoid potentially dangerous fault conditions.
battery’s short circuit current is typically estimated by dividing its open circuit voltage by its internal resistance.
Battery system circuit resistance, state of charge and temperature can reduce the nominal zero-voltage short circuit currents. Potentially dangerous short circuit conditions can be prevented with a better understanding of battery and circuit protection operation.
Estimated short circuit values can vary widely depending upon the test method and measurement technique. Multi-stepped discharge test methods that use a large span in current and voltage provide the best accuracy in estimating battery short circuit current and resistance.
Often, the peak short circuit current occurs within 5 to 15 milliseconds. Without some form of protection such as a fuse or breaker, a short circuit condition can cause permanent damage to the battery. In effect the battery can itself becomes the fuse.
