Electric car battery drum is one of the common failures of electric vehicle batteries, which directly affects the life of the electric vehicle lithium battery. Many people have encountered, and the mobile phone batteries that are generally used in general use are easy to drum, and everyone knows that lithium battery drums are very dangerous. Electric car batteries are no exception.
The reason for the electric vehicle lithium battery drum bag is the core component of the electric vehicle, the lithium battery drums this word, and believes that the riders are not strange. In recent years, the phenomenon of battery drums is not uncommon, so many consumers are very troublesome. Because once individual battery drums occur in a set of batteries, replace the entire set of batteries.
1. Safety valve pressure over high electric vehicle lithium battery has a safety valve in order to ensure safety. When the pressure in the electric vehicle battery rises, the safety valve will automatically open, and perform pressure, so that the battery can be used to ensure normal use of the battery.
And when the pressure in the battery rises, the safety valve does not open, there will be a lithium battery drum bag. 2 The precipitation is too fast, which in turn leads to insufficient chemical reactions. At the same time, if the temperature in the battery is rising very fast, the inflation is not in time, there will be a problem of drums.
3, the lithium battery of some electric vehicles in series is used in series, which can have more capacitance, and when the series battery is too much, it can cause the gas composite in the battery, thereby appearing the lithium battery drum. 4, the battery is unqualified if the lithium battery does not pay attention to the protection, there is an excessive pressure, and the lithium battery drum bag will occur. 5, charger inferior charger to the electric vehicle lithium battery is not turned back, no charge according to the battery of the battery, resulting in a large number of batteries, after multiple times, the battery will be charged.
If the charger mixed with different models can also cause the battery to be drumped. Different models of batteries, the charger is different, but some electric cars users will be used frequently in the process of use, and they will use the 60V charger charger. 48V battery, take 20AH charger charge 12AH battery , Charging voltage and current do not match, it will cause the battery to be drumped.
6. If the safety valve is not good, the electric car battery will have a safe valve. It will release too much pressure through this valve, but there is a different battery because the safety valve is not good, therefore causing lithium battery drums.
Deformation. 7, ambient temperature summer high temperature exposure battery or charging ambient temperature is too high, which will also cause deformation of the battery shell. Depending on the battery power, the charger can be floated after 2 hours, and after the ambient temperature is high, the battery surface temperature should be naturally cooled, and the electric vehicle lithium battery avoids charging in a high temperature environment.
The above four are common reasons for electric vehicles lithium battery drums, and to avoid lithium battery drums, then, in addition to mastering the cause of their drums, pay attention to two points: good batteries are also tossing, especially Many people do not pay special attention to maintenance during riding electric vehicles, rugged roads, often brakes, and excessive loads can cause lithium batteries to be damaged, and often check the battery, in order to ensure the normal operation of the battery, On the other hand, it is also to protect your personal safety and avoid accidents. How to effectively avoid lithium battery drums? 1. Develop regularly check the battery's habitual quality and good batteries will not be tossed! Especially in the process of using electric vehicles, do not pay attention to maintenance, heavy load, emergency stop, road sections, etc.
will damage the battery. What we have to do is regularly checking lithium batteries, observing whether the battery is running normally to ensure your personal safety. 2.
3. Select the matching charger battery in the process of use, the charger that matches the battery model should be selected. Take a 60V charger charge 48V battery, take 20AH charger charge 12AH battery, charging voltage and current do not match, can cause the battery to be filled.
Of course, the charger of the lead battery charger and lithium battery can also be mixed. 4, don't just use the roadside charging station, although it can be quickly charged, it is too large, the lead-acid battery cannot be affected, and the number of times is used, and it may cause a battery drum. The above is the cause of lithium battery drums, the quality of lithium battery is not limited, the battery's protective system is easy to collapse, and it is easier to cause drum phenomena.
A battery that is far from quality is not high, avoid this happening. Lithium battery drums, mainly related to battery quality, so try to choose high quality, reputation, good brand battery when choosing batteries. .
