Electric vehicle batteries and why is the drum kit
Dec 09, 2016

A, safety valve pressure too high

Electric car battery to ensure safety there is a safety valve, when pressure rises when in the electric car battery, the safety valve will automatically open, after all, release, so that you can guarantee the normal battery use. And when the rise in pressure within the battery, do not open the safety valve when there will be bubbles.

Second, the charge current is too large

Normally, regular factory production of electric car charging current of the battery has some value, and for a variety of reasons leads to high voltage, charge current is too large, it is easy to cause precipitation on the plate too fast, leading to chemical reactions is not sufficient. Meanwhile, if battery temperature rises rapidly, the exhaust does not timely, bulge will appear natural.

Three, series charging

Some electric car batteries are used in series, so you can have more capacity, and when an in-line battery charging when too many, can also lead to gas recombination within the battery is bad, thus the drum kit.

Four, battery is not a qualified

If the batteries do not pay attention to in the design of the enterprise there is a refuge from the road, and there will be too much pressure in the body, battery drum kits.

Four is the electric car battery drum kit common cause, in order to avoid battery drum kit, then, in addition to its bulge causes, but also pay attention to two points:

First, always check the batteries

Good batteries but the use of agonizing, and especially when a lot of people ride electric cars, will not pay special attention to maintenance, rugged roads, regular braking, excessive load, will cause the battery to be damaged, and always check the batteries, in order to ensure the normal operation of the battery on the one hand, on the other hand in order to protect their personal safety and avoid accidents.

Second, select brand products

Research shows that 80% people in the habit of buying cheaper when buying something, and rarely cheap can be a highly cost-effective products, therefore, useful life is usually not very high, the failure rate is very high. In response, Xiao bian recommended is better quality products, don't go for cheap, take big losses.
