The low temperature causes the inside of the rechargeable battery to freeze, thereby reducing the mechanical and chemical properties of the battery's internal resistance. It can be rotated to a suitable temperature, and after a period of time, the rechargeable battery will recover some of its working capacity. However, if used frequently, the rechargeable battery will experience a significant reduction in its lifespan due to lithium deposition at ultra-low temperatures.
In daily life, we often encounter situations where lithium batteries won't charge. The specific issues vary depending on the device, and therefore the solutions will differ. Below are some solutions for when a lithium battery won't charge, which we hope will be helpful.
It is common to encounter situations where lithium batteries cannot be charged:
1) What to do if my mobile phone lithium battery won't charge?
1. If a mobile phone lithium battery fails to charge due to large temperature fluctuations, this is often because lithium batteries are not designed for low-temperature environments. When used in extremely cold conditions, the battery's internal structure can freeze, increasing internal resistance and reducing chemical activity, leading to a sharp decrease in discharge capacity, or even preventing discharge altogether. Simply moving the battery to a suitable temperature environment will allow it to recover some capacity after a period of time. However, prolonged use at low temperatures can cause lithium plating, severely reducing the battery's lifespan or rendering it unusable.
2. If your phone battery is frequently used while charging, and this prevents it from charging properly, then the battery is likely degrading too quickly due to constant high-activity charging, eventually reaching the end of its lifespan. In this case, the battery needs to be replaced.
3. A possible short circuit caused by a faulty charging port may trigger the phone's battery protection board, preventing charging. This requires inspection and repair of the charging port.
4. If your phone works while charging but gets very hot, and then quickly runs out of power or completely stops charging, the battery is likely bulging or damaged and needs to be replaced.
5. If a mobile phone's lithium battery automatically shuts down outdoors without being charged, and remains uncharged for an extended period (usually about a week), the battery is still in a low-current self-discharge phase. Prolonged self-discharge can deplete the battery, resulting in excessively low charge and preventing it from charging. In this case, try using a charger with a higher output voltage (voltage difference should not exceed 3V) for activation charging. Monitor this process closely. Once the battery has a certain amount of charge and can be used normally, switch to a regular charger for continued charging.
6. Another possibility is that the charger is faulty, so it is recommended to check the charger first.
2) What to do if the lithium battery of an electric vehicle won't charge?
1. If an electric vehicle battery fails to charge due to large temperature fluctuations, it's often because the battery itself isn't designed for low-temperature operation. When used in a cold environment, the battery's internal structure can freeze due to the extremely low temperature, increasing internal resistance and reducing chemical activity. This leads to a sharp decrease in discharge capacity, or even complete failure to discharge. Simply moving the battery to a suitable temperature environment will allow it to recover some capacity after a period of time. However, prolonged use at low temperatures can cause lithium plating, severely reducing the battery's lifespan or rendering it unusable.
2. If an electric vehicle's lithium battery is frequently completely discharged, also known as excessive deep discharge, and this prevents the battery from charging (assuming the charger is working properly), then the battery is degrading too quickly due to frequent high-activity discharge, eventually reaching the end of its lifespan. In this case, the battery must be replaced.
3. A possible short circuit caused by a faulty charging port may trigger the electric vehicle's lithium battery protection board, preventing charging. This requires inspection and repair of the charging port.
4. Another issue could be a problem with the electric vehicle's lithium battery charger, so it's recommended to check the charger first.
3) What to do if the car's lithium battery won't charge when starting?
1. If a car's lithium-ion battery fails to charge due to large temperature fluctuations, it's often because lithium-ion batteries are not designed for low-temperature environments. When used in cold environments, the battery can freeze internally due to the low temperature, increasing internal resistance and reducing chemical activity, resulting in a sharp decrease in discharge capacity, or even complete failure to discharge. Simply moving the battery to a suitable temperature environment will allow it to recover some capacity after a period of time. However, prolonged use at low temperatures can cause lithium plating, severely reducing the battery's lifespan or rendering it unusable.
2. A possible short circuit caused by a malfunction in the charging port of the car's starting lithium battery may trigger the protection function of the car's starting lithium battery protection board, preventing it from charging. This requires inspection and repair of the charging port.
3. After a period of time, the lithium battery in a car will enter a dormant state.
It may not charge at first and will take a long time to charge. Generally, it can be activated and restored to normal capacity after 3-5 normal charge-discharge cycles. It is recommended to use the standard charging method for this "natural activation" method, which is the best.
4. Another possibility is that the charger is faulty, so it is recommended to check the charger first.
