Classification of new energy automobile power lithium battery, maintenance method of dynamic lithium-ion battery pack. With regard to new energy vehicles, the battery is the life of new energy vehicles. There is no battery.

It is the battery of the new energy car, and the consumer is also the first to pay attention to the quality of the battery when purchasing new energy cars. The classification power lithium battery of the new energy vehicle power lithium battery is important from the positive electrode, the negative electrode, the electrolyte, the diaphragm, etc., requires high energy density, long life, reliable safety; its working principle is between the positive and negative electrode material and the electrolyte Electroless movement occurs.

Classification of new energy automobile power lithium batteries 1, lithium-ion battery: is one of the most common battery types on electric vehicles, although it is not long since 1970, it is not long, but with high energy density, circular service life The feature quickly occupies the vast majority of the electric car battery market, and now there is two kinds of lithium ion batteries and ternary lithium ion batteries that sell the electric car. 2, NiMHD battery: It is the only battery system in which the battery system used in hybrid vehicles is actually verified and commercialized, larger, and 99% of existing hybrid lithium batteries are nickel-hydrogen powered lithium batteries. Commercial representative is Toyota's Prius.

3, fuel power battery: It is a device that fuel and oxidant to directly convert its chemical energy into electrical energy by electrode reaction. The fuel power battery should not be charged, which has the advantages of higher energy, long service life, less maintenance work, and sustained high power supply. In addition, the fuel power battery vehicle can reach the same continuation mileage as the fuel car.

4, lead-acid battery: as a relatively mature technique, due to its low cost, and can discharge high-magnification, is the only electric vehicle for large quantities of electric vehicles. However, it is very low in lead-acid batteries, compared to power, and energy density, and this electric vehicle that is power source cannot have a good vehicle speed and battery life. 5, graphene battery: About the power lithium battery of future new energy vehicles, most reliable, discussion is the graphene battery.

Based on this material to combine lithium ion battery, there are two methods of use: First, the composite of graphene is used as a conductive agent of a lithium ion battery; the second is to directly use it as a negative electrode, and the effect is the activity of the lithium ion battery pack, thereby Improve the battery life, charging speed. Maintenance method of dynamic lithium-ion battery pack 1 Regular test: In the process of use, if the mileage of electric cars suddenly falls in a short period of time, it is likely that there is a minimum battery in the lithium-ion battery pack. Short-circuit phenomenon such as grid, polar plate softening, polar active substance.

At this point, you should check, repair or group in time to professional battery repair mechanism. This can relatively extend the life of the power lithium-ion battery pack to maximize expenditure. 2 Prohibiting the direct and negative of the power lithium ion battery pack to prevent any metal or other conductive object other than the battery pole press bolt and the conductive belt to contact the positive and negative electrode of the power lithium ion battery, this operation may cause the personal Damage or property loss.

3 Note Temperature: The power lithium-ion battery pack must not be exposed to a high temperature, if the temperature exceeds 60 degrees, then the battery will be transferred in time; the temperature is too high not only destroy the internal structure of the battery, but also Danger. 4 Note: When using the power lithium-ion battery pack, in order to ensure that it is necessary to pay attention to the first parallel, if you buy a custom battery pack, then you don't have to worry about this problem. If your lithium-ion battery group is made by yourself, you must pay attention to the problem of tandem and parallel.

The above is the classification of new energy vehicle power lithium batteries and maintenance methods of dynamic lithium-ion battery packs. The energy source of electric vehicles, since the birth of electric vehicles, the power lithium battery technology has always been one of the key factors affecting the practical process of electric vehicles. Improve power density, energy density, service life, and reduce costs have always been the core of electric vehicle power lithium battery technology.
