1. Lead acid battery short circuit is mainly shown in the following aspects： 1.1 The open circuit voltage is low, and the closed circuit voltage (discharge) quickly reaches the end voltage. 1.2 When discharging at high current, the terminal voltage drops to zero rapidly.
Practical considerations such as the effects of temperature, state of charge and type of circuit protection device are also presented. battery’s short circuit current is typically estimated by dividing its open circuit voltage by its internal resistance.
2. The main reasons for the internal short circuit of the lead-acid battery include: 2.1 The quality of the separator is poor or defective, allowing the active material of the plate to pass through, resulting in virtual or direct contact between the positive and negative plates.
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.
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.
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.
