Electric vehicles need safe and efficient batteries as power sources. Lithium battery is used as the ideal power source of new generation electric vehicles because of its advantages such as stable working voltage, high energy density and charging efficiency, low self discharge rate, no memory, and long service life. How to accurately estimate the remaining battery power is of great significance for improving the maximum utilization rate of lithium batteries and continuously optimizing battery technology. In the research and development of electric vehicles, accurate prediction of battery SOC plays an important role in exerting the best performance of electric vehicles and predicting the driving range of electric vehicles. However, the state of charge of lithium battery can not be directly measured, and is affected by many factors, such as the rate of charge and discharge, the aging degree of the battery, and the internal resistance of the battery, which makes…

With the continuous development of lithium battery industry, at present, there are three main packaging forms of lithium battery, namely, cylindrical, square and soft package. Different packaging structures mean different characteristics. Soft pack battery The flexible lithium battery is a polymer shell on the liquid lithium ion battery. The biggest difference between the flexible packaging material (aluminum plastic composite film) and other batteries is that it is also the most critical and technically difficult material in the flexible lithium battery. The packaging material and structure of the flexible battery make it have many advantages.(1) Good safety performance: the electrolyte of the soft packed battery leaks less, and the soft packed battery will burst when there is a potential safety hazard, unlike the hard shell battery, which will explode if the internal pressure is too high;(2) Light weight: the weight of the soft packed battery is 40% lighter than that of…

No! Any electrical equipment shall have a charger specially matched with it and shall not be mixed. The charger with small power can not only take the equipment with large power, but also easily damage the electrical equipment; Use a charger with high power to charge the electrical equipment with low power, which may burn the electrical equipment immediately.For example, if you use a 120 volt power supply to light a 220 volt lamp, you should not light it at all; Or even if it is barely bright, it is not bright. On the contrary, if you use 220 V electricity to light a 120 V lamp, it may explode with a flash. The results will not be so extreme if the match is not very different, but it will not withstand long-term use and will also damage electrical equipment. The voltage of the 20% charger is low. If the…

The battery is a device with “electricity storage”, which is of great importance to the car model driven by “electricity”. Therefore, it is very important for car owners to choose the right battery. I have previously introduced the types of batteries, the differences and selection methods of lithium batteries, lead acid batteries and graphene batteries. Today, experts continue to introduce to you what are the differences between 72 volt and 60 volt batteries in terms of battery parameters? How to choose more durable and long distance? If it is an electric car, which one should I choose? One time, I hope that you can see the knowledge later. Before introducing 72 V and 60 V, let’s first understand what “V” means. It is actually the unit of voltage, and the voltage is the potential difference of the battery. The voltage will affect the endurance, power and many other aspects of…

According to the upper limit of charging voltage, polymer lithium batteries can be divided into high-voltage lithium batteries (4.35V/4.4V) and conventional lithium batteries (4.2V). The nominal voltage of conventional voltage batteries is 3.6/3.7V, the upper limit of charging voltage is 4.2V, the nominal voltage of high-voltage lithium batteries is 3.8V and 3.85V, and the corresponding charging cut-off voltages are 4.35V and 4.4V respectively. High voltage lithium batteries have only been widely used in the market in recent years, and they are also the commanding heights of the technical competition of high-voltage battery manufacturers. But how to charge the high-voltage lithium batteries is better. I believe many people still have this question. Today, Graeme Technologies will explain how to better charge the high-voltage lithium batteries? Charging mode of high-voltage lithium battery

Battery leakage is mainly caused by uncontrollable chemical changes or long-term use. 1. When the battery is in use, if the output current is too large, the internal instantaneous temperature of the battery will rise, the balance will be broken, and liquid leakage will occur. Even if the current is small, it may leak if it is used for a long time. 2. The outer layer of the battery is generally made of zinc and other materials, the middle is a carbon rod, and between the carbon rod and the zinc in the outer layer is an electrolyte. The discharge of dry battery is mainly through the loss of electrons on the zinc cylinder, which is oxidized into Zn2 and enters the electrolyte solution. The electrons obtained by NH4 in the electrolyte solution are reduced to NH3. The zinc loses electrons in the reaction. As the cathode, with the consumption…
