What causes a lithium battery pack to malfunction?

However, failures can cause lithium battery packs to malfunction. The type of problem will be based on the construction of the battery pack, how it is charged, how it is used and handled, and environmental factors.

What causes a lithium ion battery to fail?

One of the most common failures is the result of the battery pack overheating. Overcharging the battery is one cause to heating issues. The excess charge combines with higher temperatures (such as direct sunlight). The battery pack experiences an increased level of stress. Thermal runaway is another factor that can impact lithium ion batteries.

What happens if you use the wrong battery pack charger?

Using the incorrect charger for the lithium battery pack can also cause a range of problems. Most battery pack chargers for lithium-ion batteries are designed to prevent overcharging. However, using the wrong charger can cause overcharging or over voltage of the lithium battery pack as well as swelling.

What causes a battery pack to swell?

Swelling can occur for a number of reasons. For example, moisture may have intruded into the battery pack. Overcharging is also a common reason for battery pack swelling. Aging can also cause the battery pack to swell. As it ages, the battery pack can cause an elevation in temperatures. Example of a swollen lithium battery pack.

What happens if a battery pack is leaking?

Battery pack with cell leakage due to outgassing. Users who have electrolyte leakage should take the necessary precautions to not come in contact with the liquid or the electrolyte residue. The electronics that come in contact with the electrolyte leakage can also short circuit. You may notice that the battery enclosure is large and bulging.

What happens if a battery cell fails?

Consequently, the electrolyte may cause propagating circuit board failures, leading to external heating of the cell and forcing the cell into thermal runaway. Safety issues can occur when the battery cell or the circuit is mechanically stressed or damaged.

Examining Failures in Lithium-ion Batteries

Lithium-Ion battery cell failures can originate from voltage, temperature, non-uniformity effects, and many others. Voltage effects can occur either due to overvoltage or undervoltage effects. Overvoltage effects happen when there is an increase in the charging voltage of the cell beyond the predetermined upper limit of 4.2 V per cell.

Lithium ion battery degradation: what you need to know

Low temperatures, high SoC, high (charge) current, high cell voltage and insufficient NE mass or electrochemically active surface area can all cause lithium plating. It is standard practice to put 10–20% spare capacity in the NE to prevent overcharge. 35 Local overcharge can also occur at the edges of the electrode, so spare surface area or "overhang" …

Fault diagnosis and abnormality detection of lithium-ion battery packs …

From the detection results and the voltage variation trajectories of cells, it can be concluded that the detected abnormality is a rapid descent of voltage caused by the battery pack that is discharged with a high rate current in a low voltage stage. This kind of improper behavior that the E-scooter operates in the extreme environment may trigger the over-current and under …

5 Reasons for Battery Failure

High Cut-off Voltage. In the case of rechargeable batteries, manufacturers prescribe a cut-off voltage for the batteries. The voltage at which a battery is supposed to have discharged is its cut-off voltage. Actually, there is still some power left in it, but this threshold for recharging ensures longer battery life. Many portable device ...
