The difference between battery car big battery and small battery ternary lithium ion battery

The difference between battery car big battery and small battery ternary lithium ion battery

Release date:2018-11-16 author: clicks:

The difference between a battery car big battery and a small battery ternary lithium ion battery is:


1. The size of the battery generally refers to the size of the battery (of course, the volume and weight of the battery are also the same). For example, the battery capacity is 20AH, which means that the electric current of 1A can be used for 20 hours.


2. The larger the battery capacity value, the more electricity the ternary lithium-ion battery stores. The more the battery car can travel or the longer it runs.


3. Reasonably select the battery capacity and obtain the maximum price-to-price ratio. For example, choose the battery capacity that is 3 times the distance of the regular activity (work), which can ensure normal driving, the lowest payment cost, and so on.


The size of the battery determines its capacity and power.


(For example: I put two different sizes of batteries and two bottles of different sizes, then you say that the big bottle is filled with more water or the smaller bottle is more water / that is definitely a big bottle!! The difference is here!!)


The battery voltage and capacity are printed on the battery!


The big battery car can run faster and can run longer! (Small battery will not say)


If you don't understand, you can HI me! !


There are two main types of lithium iron phosphate lithium ion batteries used in automobiles, one is a lead-acid battery with an electrolyte (wet type), and the other is a maintenance-free type battery (dry type). The length of service life of a car battery depends not only on the structure and quality of the battery, but also on its operation and maintenance.


The maintenance-free battery (dry type) is completely sealed without adding distilled water and adjusting the concentration of the electrolyte. Generally, no electrolyte overflows onto the surface of the battery.


The maintenance of the battery (wet) is more troublesome. In addition to the maintenance items of the maintenance-free battery mentioned above, the following two aspects should be noted: First, check and adjust the height and concentration of the electrolyte of lithium iron phosphate lithium ion battery, electrolysis The height of the liquid should be between the highest (MAX) and the minimum (MIN). Too low will reduce the capacity of the battery and cause the plate to vulcanize. If it is too high, it will overflow to the surface of the battery to corrode the poles, wires and the body. The concentration of the electrolyte has a great influence on the working condition of the battery.


At present, every battery of a car (mostly called a battery in a car) is 12V, each battery has a large capacity, and the smallest car battery has a capacity of 32 Ah. If the capacity is small, it is possible for the car, but it is not easy to start in winter.


Your question is not clear. There are two kinds of electric vehicles. One is electric bicycles (including electric motorcycles, electric bicycles, electric wheelchairs, electric handicapped vehicles, electric tricycles, electric freight cars, electric police cars, etc. ), the other is an electric car. Electric vehicles are divided into fully charged and hybrid electric vehicles.


Let me talk about electric bicycles. One battery has 12V and 20V. Of course, there are 36V, 48V, 60V, or even 72V. Of course, these voltage electric vehicle batteries are all obtained by combining different battery cells. Moreover, the capacity of the electric bicycle battery is much smaller than that of the automobile. Most of the battery capacity is 20Ah, and the capacity is also 10Ah, 12Ah, 14Ah, 30Ah, 36Ah, 42Ah, 50Ah, 58Ah, 60Ah, 76Ah and other different specifications. Generally, most electric bicycles use 20Ah, and some large electric vehicles such as electric vehicles and electric vehicles use batteries with larger capacity. There is no national standard for the battery capacity of electric bicycles.


In order to reduce the trouble and safety of the rider, electric bicycles mostly use maintenance-free battery (dry) batteries.


Then talk about electric cars. Electric vehicles At present, lithium manganese oxide lithium ion batteries are a major trend in replacing fuel vehicles. However, due to the limitation of the manufacturing process and manufacturing technology of the battery, the unit power of the battery is small and the unit volume is large. As a result, the electric vehicle is still in the stage of development and trial use, and is not fully put into the market. There are also some hybrid vehicles that are also developed and produced by different automobile manufacturing companies. These companies have not agreed on battery voltage standards and battery capacity standards. Just one thing, the batteries used in most hybrid cars today are nickel-metal hydride batteries.


Also, the terminal of the car battery is a standard car battery head, and the battery connector of the electric car is a screw or a lead connector.


The amount of electricity discharged by the battery under specified conditions (including discharge intensity, discharge current and discharge termination voltage) or the length of discharge time is called battery capacity, and the unit is A·h or A·min. A car battery is a reversible DC power source that converts chemical energy into electrical energy and electrical energy into chemical energy. It is connected in parallel with the generator.


It supplies power to the starting system and the ignition system during engine start.


When the engine is stopped or low idle, it supplies power to the vehicle's electrical equipment.


When there is a demand for electricity exceeding the output of the charging system, it provides current for a limited period of time.


The battery also absorbs the transient overvoltage in the circuit to keep the voltage of the automotive electrical system stable and protect the electronic components.


If the battery is not used for a long time, it will slowly discharge itself until it is scrapped. Therefore, the car should be started once every certain time to charge the battery. Another method is to pull out the two electrodes on the battery. It is necessary to remove the positive and negative electrode wires from the electrode column. First, unplug the negative wire or remove the connection between the negative electrode and the chassis of the car. Then remove the other end with the positive mark (+). The battery has a certain service life and will be replaced in a certain period of time. The same order should be followed when replacing, but when the electrode wires are connected, the order is reversed, first connected to the positive electrode and then to the negative electrode.


When the ammeter pointer indicates that the storage capacity is insufficient, it should be charged in time. The storage capacity of the battery can be reflected on the instrument panel. Sometimes the power is not enough on the road, and the engine can't start. As a temporary measure, you can ask other vehicles for help. Use the battery on the vehicle to start the vehicle, connect the negative and negative poles of the two batteries, and connect the positive pole to the positive pole. .


The density of the electrolyte should be adjusted according to the standard according to different regions and seasons.


Distilled water or special rehydration solution and nano-carbon sol battery activator should be added when the electrolyte is deficient. Never use pure water instead. Because pure water contains a variety of trace elements, it will have an adverse effect on the battery.


Uninterrupted use of the starting opportunity when starting the car causes the battery to be damaged due to excessive discharge. The correct method of use is to take no more than 5 seconds for each time the car is started, and the interval between starts again is not less than 15 seconds. In the case of multiple starts and still not in the car, you should find the reason from other aspects such as circuit, ignition coil or oil circuit.


Always check the small holes in the battery cover for ventilation when driving daily. If the small hole of the battery cover is blocked, the generated hydrogen and oxygen will not be discharged, and when the electrolyte expands, the battery case will be broken and the battery life will be affected.


Check the positive and negative levels of the battery for signs of oxidation. You can use hot water to constantly pour the wire connection of the battery.


Check the presence or absence of aging or short-circuiting in all parts of the circuit to prevent the battery from being decommissioned early due to excessive discharge.


Over discharge


2. The battery is stored for a long time (not charged during storage)


3. Cannot be charged by car engine


4. No electrolyte


5. The electrolyte is too high


6. Charging under high temperature conditions


7. Contaminated by contaminated materials (such as hydrochloric acid, sea water, organic acids, etc.)


8. Add excessive current when charging the battery


9. The deformation of the electrode plate causes the positive plate and the plate to contact each other, thus causing a short circuit.


10. Deposits on the upper and lower parts of the pole, causing a short circuit


11. As long as you pay attention to avoid the above points, the service life of your battery will increase accordingly.
