With the increasing application of lithium batteries, accidents of lithium batteries often occur. Among many accidents of lithium batteries, explosion is the most common. If we avoid the explosion of lithium batteries, the following discussion will be of great help to our use.
How to properly maintain and use lithium battery?
I. overcharge danger: Unplug the charger in time after full charge, and keep charging for no more than 8 hours.
In life, many users buy lithium battery electric vehicles home, will choose according to the lead-acid battery charging method, the first three to five times to charge the battery in 10-12 hours. However, lithium batteries do not need to be activated in this way, which will affect the life of lithium batteries. More exotic people say that the battery of an electric car will continue to charge for another hour after it is fully charged. It's also wrong to do this. The right thing to do is to turn off the power supply directly after it's full of electricity. Lithium batteries should not be charged overnight and continuously for more than eight hours in case of fire.
2. Do not charge and discharge lithium batteries in depth frequently
Many people think that the number of times lithium batteries are recharged hundreds of times in the instructions of electric vehicles is just once plugged in and out, even once used. In fact, this is a misunderstanding. The number of times on the instruction is actually the number of times the charge and discharge are completed. Lithium batteries are different from nickel-cadmium batteries. Lithium batteries have no memory effect. It can be charged at any time, and it can also maintain the battery when there is surplus electricity. For lithium batteries, the correct way to turn on is slow charging.
3. Lithium batteries are afraid of cold and heat, and should not be used in extreme environments.
In daily life, the parking problem of electric vehicles is very easy to be ignored. In summer, electric vehicles are exposed to the sun, and in winter, they are randomly parked on the roadside or in the yard. This has a great impact on the service life of lithium batteries. Because the transport rate of lithium ions in lithium batteries in electrolytes and electrodes is directly related to temperature. In theory, the working temperature of lithium-ion batteries can work normally between - 20 and 55 C, but when using lithium-ion batteries, it should be noted that the temperature between 5 and 35 is harmless to lithium-ion batteries, and the temperature beyond the range will cause certain damage to the batteries. So users in the North should store batteries at home as much as possible in winter, not outdoors. At the same time, attention should be paid to avoiding summer sun exposure.
4. Charge with an adapted charger to avoid high current
Because lithium ions in lithium batteries are very active, the chemical activity of lithium batteries is much more active than that of lead-acid batteries. So the requirements for lithium battery chargers are very high. Once miscellaneous chargers or unsuitable fast chargers are used, the service life of lithium batteries will be affected, and even explosions will occur because of excessive temperature. So when charging, use your own original or adapted charger. Avoid roadside fast charging pile as far as possible, because the rated voltage of fast charging pile is very large, although it is very convenient to use, but the battery damage is very serious.
Attention to the above points can prolong the service life of lithium batteries and minimize the risk of spontaneous combustion of electric vehicles. Finally, let me remind you that the charging of electric vehicles should avoid charging in narrow and inflammable places such as indoor or corridor, and should choose open and dry outdoor charging.
