The battery external short circuit test, which evaluates the electrical performance and safety of batteries by short circuiting them from outside to simulate use that may cause fire or rupture. ESPEC can carry out external short circuit tests with high currents of up to 24 kA (a world-first).
You may also notice that the battery becomes hot or swollen during use, which can indicate a short circuit. Finally, you can use a multimeter to test the voltage of each cell in the battery. If one cell has a significantly lower voltage than the others, it may be shorted.
Tests to evaluate the electrical performance or safety of lithium-ion batteries and other secondary batteries include continuous charging tests, external short circuit tests, overcharging tests, over-discharging tests, and large-current tests. External short circuit tests simulate incorrect battery usage.
Disconnect the battery, starting with the negative (-) terminal followed by the positive (+) terminal to avoid accidental short circuits. Look for cracks, bulges, or leaks. If you see any of these signs, replacing the battery is best. Over time, corrosion can build up on the battery terminals, which might cause a short.
Any wire connecting to a sensor can touch or short with another wire that is battery positive ie 12V+ so the sensor is fed directly from the battery. What will the sensor do in those conditions? Fail open circuit or fail short circuit? If short circuit then will that cause a fire or damage to other wiring?
Connect the positive (+) terminal first, followed by the negative (-) terminal. Ensure the connections are tight and secure. If you’ve addressed the potential external causes and still suspect an issue with the battery, consider conducting a load test. This requires a specific tool and can be done at most auto parts stores or mechanic shops.
