Several solutions for lithium-ion batteries that cannot be charged

1. How to deal with if the mobile phone lithium ion battery cannot be charged (1) The mobile phone lithium ion battery cannot be charged due to the large environmental temperature change. This situation is mostly because the lithium ion battery itself is not a low-temperature battery and is changing to a low-temperature environment When it is used, it will freeze inside the battery due to the low temperature, which will increase the internal resistance of the battery and decrease the chemical activity, resulting in a sharp drop in the discharge capacity, or even no discharge. This can be transferred to a place with a suitable temperature. After a period of time, the battery will recover part of its capacity. If it is used frequently, the battery's life will be seriously attenuated or scrapped due to the low-temperature evolution of lithium ions. (2) When the mobile phone battery is in use, it is often used while charging. This behavior causes the battery to charge. If the charger is normal, then the battery is often in a highly active state, which causes the battery to decay too fast and the life is exhausted. . This can only be replaced by the battery. (3) The battery protection board of the mobile phone triggers the protection function and cannot be charged due to the possible short circuit caused by the failure of the charging interface. This requires overhauling the charging interface. (4) The mobile phone can be used when it is charged, and it is easy to get hot. After it is not charged, it will soon be out of power or directly out of power. In this case, the battery may be swollen or scrapped. This can only be replaced. (5) Since the mobile phone lithium-ion battery is not charged outdoors, it has not been charged for a long time after the automatic shutdown, usually about a week. At this time, the lithium-ion battery is still in low-current self-discharge, and the time is too long, or the battery will be exhausted, that is, over-discharge, causing the battery to be too low and unable to charge. At this time, you can replace the charger with a higher output voltage (the pressure difference should not exceed 3V) for activation charging. This should always be paid attention to. Once the battery can be charged and has a certain amount of power, the replacement will be normal for the charger to charge. (6) Another problem is that there may be a problem with the charger, so it is recommended to check the charger first. 2. What should I do if the lithium-ion battery of an electric vehicle cannot be charged? (1) The electric vehicle battery cannot be charged due to a large environmental temperature change. This situation is mostly because the electric vehicle battery itself is not a low-temperature battery and is changing to a low-temperature environment. When it is used, it will freeze inside the battery due to the low temperature, which will increase the internal resistance of the battery and decrease the chemical activity, resulting in a sharp drop in the discharge capacity, or even no discharge. This can be transferred to a place with a suitable temperature. After a period of time, the battery will recover part of its capacity. If it is used frequently, the battery's life will be seriously attenuated or scrapped due to the low-temperature evolution of lithium ions. (2) Lithium-ion batteries in electric vehicles are often used up when they are in use, which is often said to be excessive deep discharge. This behavior causes the battery to be unable to charge. If the charger is normal, then the battery is often in high activity. Under the condition of power consumption, the battery will decay too fast and its life span will be exhausted. This can only be replaced by the battery. (3) The electric vehicle lithium-ion battery protection board automatically triggers the protection function and cannot be charged due to the possible short circuit caused by the failure of the charging interface. This requires overhauling the charging interface. (4) Another problem is that there may be a problem with the charger of the lithium-ion battery of the electric vehicle, so it is recommended to check the charger first. 3. How to deal with if the lithium-ion battery cannot be charged when the car starts (1) The lithium-ion battery cannot be charged due to the large environmental temperature change. This situation is mostly because the lithium-ion battery itself is not a low-temperature battery. When it is used in a low temperature environment, the internal resistance of the battery will increase and the chemical activity will decrease due to the low temperature, which will cause the battery's internal resistance to increase and the chemical activity to decrease, resulting in a sharp drop in the discharge capacity, or even no discharge. This can be transferred to a place with a suitable temperature. After a period of time, the battery will recover part of its capacity. If it is used frequently, the battery's life will be seriously attenuated or scrapped due to the low-temperature evolution of lithium ions. (2) A possible short circuit is caused by the failure of the charging interface of the car's starting lithium-ion battery, so that the car's starting lithium-ion battery protection board automatically triggers the protection function and cannot be charged. This requires overhauling the charging interface. (3) The car starts the lithium-ion battery and enters the dormant state after being placed for a period of time. This may not be able to charge at the beginning, and it needs to be charged for a longer time. Generally, the battery can be activated after 3-5 normal charge and discharge cycles, and the normal capacity can be restored. It is recommended to use the standard method of charging, which is the best natural activation method. (4) Another problem is that there may be a problem with the charger, so it is recommended to check the charger first.
