As more and more electric vehicles enter thousands of households, making people travel more convenient and faster, but without enough battery power as a driving force, it will also bring trouble to people in the process of driving. Most electric vehicles on the market today use lithium batteries. Although lithium batteries rarely have the memory effect of nickel-cadmium batteries, the principle of memory effect is crystallization, and this reaction is hardly produced in lithium batteries. However, the capacity of lithium battery electric vehicles will still decrease after repeated charging and discharging. The reason is complicated and diverse. It is mainly the change of the positive and negative materials themselves. From the molecular point of view, the hole structure of lithium ions is accommodated on the positive and negative electrodes. It will gradually collapse and block; it will eventually reduce the number of lithium ions in the lithium battery electric vehicle battery that can move freely during charging and discharging. For the first charge of the lithium battery, the charging time and method of the lithium battery, Xiaobian will be explained in detail below. Note that this is wrong It is wrong to blindly pursue the 12-hour ultra-long charge and the use of lithium battery power to automatically lose power. If you have done it in the wrong way, please correct it in time. Correct use The correct use of lithium batteries actually comes down to 3 points, Xiaobian summarized the following three major charge and discharge problems: 1. Charge according to the standard time and procedure, even if it is the first three times; (Small PS: In particular, do not charge more than 12 hours) 2. When the lithium battery appears to be too low when the electric vehicle is running, the lithium battery should be charged as soon as possible. (Small PS: This is strongly not recommended for fast charging stations, super damage to the battery. The market said that the battery is running out of recharge and the battery is charging for a long time is not all right, it depends on the type of battery, for "try to put The electric vehicle battery runs out of power, and it is best to use it. It is only used on nickel batteries. The purpose is of course to avoid battery memory effects.) 3, lithium battery electric vehicle activation does not require a special method, the lithium battery will naturally activate in the electric vehicle driving. If you deliberately use the "first three 12-hour long charge activation" method that is circulated, it will only be futile and have no effect. Lithium battery daily maintenance and preservation The lithium primary battery has a very low self-discharge, and can be stored for 3 years. It can be stored under refrigeration conditions, and the effect will be better. It is a good method to store the lithium primary battery in a low temperature place. The lithium battery can be stored for more than half a year at 20 ° C because of its low self-discharge rate and most of its capacity can be recovered. The self-discharge phenomenon of lithium batteries, if the battery voltage is stored for less than 3.6V for a long time, it will cause the battery to over-discharge and damage the internal structure of the battery, reducing battery life. Therefore, the lithium battery stored for a long time should be recharged every 3 to 6 months, that is, the charging voltage is 3.8~3.9V (the optimal storage voltage of the lithium battery is about 3.85V), which is not suitable for filling. Lithium batteries have a wide application temperature range. They can still be used outdoors in the winter in the north, but the capacity will be much reduced. If you return to room temperature, the capacity can be restored and affected by a certain temperature. Unlike lithium-ion batteries, lithium primary batteries cannot be charged and charging is dangerous. Other precautions, equivalent to lithium-ion batteries. The car purifier is also called a car purifier or a car Air Purifier, which usually consists of a high-voltage generating circuit negative ion generator, a micro fan, an air filter and other systems. Its working principle is as follows: the micro-fan (also known as ventilator) in the machine circulates the air in the car, and the polluted air passes through the PM2.5 filter and activated carbon filter in the machine to filter or adsorb various pollutants, and then After the negative ion generator installed at the air outlet (the high voltage in the negative ion generator generates DC negative high voltage during operation), the air is continuously ionized to generate a large number of negative ions, which are sent out by the micro fan to form an air flow of negative ions to achieve the purpose of cleaning and purifying the air.
