一、安全阀压力过高
1、 Relief valve pressure too high
电动汽车电池为了保证安全都会有一个安全阀，当电动汽车电池内的压力上升的时候，安全阀会自动打开，毕竟进行释压，这样就能保证电池的正常使用。而当电池内的压力上升，安全阀却打不开的时候，就会出现鼓包的情况。
In order to ensure safety, electric vehicle batteries will have a safety valve. When the pressure in the electric vehicle battery rises, the safety valve will open automatically. After all, the pressure will be released, so as to ensure the normal use of the battery. When the pressure in the battery rises, but the safety valve cannot be opened, there will be a bulge.
二、充电电流过大
2、 Excessive charging current
通常情况下，正规厂家生产的电动汽车电池都是有一定的充电电流值的，而因为各种原因导致的电压过高、充电电流过大，就很容易导致电极板上的析出过快，进而导致化学反应不充分。而与此同时，如果电池体内的温度上升很快，排气却不及时，自然就会出现鼓包的情况。
Usually, the electric vehicle batteries produced by regular manufacturers have a certain charging current value, and the excessive voltage and charging current caused by various reasons can easily lead to too fast precipitation on the electrode plate, resulting in insufficient chemical reaction. At the same time, if the temperature in the battery rises rapidly and the exhaust is not timely, the bulge will naturally occur.
三、串联过充电
3、 Series overcharge
有些电动汽车的电池是串联使用的，这样可以拥有更多的电容，而当串联电池充电过多的时候，也会导致电池内气体复合不良，从而出现鼓包的情况。
Some electric vehicle batteries are used in series, which can have more capacitance. When the series battery is overcharged, it will also lead to poor gas recombination in the battery, resulting in bulging.
四、电池不合格
4、 Unqualified battery
如果电池在设计之时不注意对企业的化留留有避道的话，就会出现体内压力过大，电池鼓包的情况。
If the battery is not designed to avoid the chemical retention of the enterprise, there will be too much pressure in the body and the battery will be bulging.
以上四种是电动汽车电池鼓包常见的原因，而要想避免电池鼓包，那么，除了掌握其鼓包的原因之外，还要注意两点：
The above four reasons are common for battery bulging of electric vehicles. In order to avoid battery bulging, in addition to mastering the reasons for battery bulging, two points should be paid attention to:
、经常检查电池
First, check the battery frequently
再好的电池也经不过使用的折腾，尤其是很多人在骑电动汽车过程中并不会特别注意保养，道路崎岖、经常急刹车、载重过多等都会导致电池是受损，而经常检查电池，一方面是为了保证电池的正常运行，另一方面也是为了保护自己的人身安全，避免出现意外状况。
No matter how good the battery is, it can't stand the toss of use. In particular, many people don't pay special attention to maintenance when riding electric vehicles. Rugged roads, frequent sudden braking and excessive load will lead to battery damage. Regular battery inspection is not only to ensure the normal operation of the battery, but also to protect their personal safety, Avoid unexpected situations.
第二、选品牌产品
Second, choose brand products
调查研究表明，百分之八十的国人在买东西的时候会习惯性的买便宜的，而便宜的产品能有高性价比的很少，因此，使用年限通常都不会很高，出故障率却会很高
The survey shows that 80% of Chinese people will habitually buy cheap products when shopping, while few cheap products can have high cost performance. Therefore, the service life is usually not very high, but the failure rate will be very high
