Description

technical field [0001] The invention relates to the field of power supplies for electric vehicles, in particular to a charging management system for electric vehicle power batteries Background technique [0002] At present, with the development of society, the explosion of automobiles has brought about environmental pollution caused by exhaust emissions. The smog weather remains high and seriously affects people's health. Low-carbon environmental protection has become a luxury for people, and pure electric vehicles have emerged as the times require. . Among the three major elements affecting the development of electric vehicles, the battery, the motor, and energy saving, the battery is the key, and the difficulty of charging the battery is the main bottleneck affecting the development of electric vehicles. At present, the charging methods that can be selected mainly include: charging pile charging, inductive charging, remote control wireless charging, microwave charging, et...

AI Technical Summary

Problems solved by technology

At present, the charging methods that can be selected mainly include: charging pile charging, inductive charging, remote control wireless charging, microwave charging, etc., among which the latter three charging methods are low in efficiency and difficult to implement, and are currently vigorously promoting charging pile charging at all costs. Charging, but this method obviously has nine major defects: 1. The charging time is too long, as little as half an hour, as many as several hours, such a long time is unacceptable to people, and it is also difficult for charging merchants to maintain ;2. For the damage to the battery itself, no matter what kind of battery there is an optimal charging procedure, it is impossible for people to charge according to this dogmatic procedure due to various reasons. It is caused by improper charging. People do whatever they want when charging due to various situations. In an emergency, just charge a little and go away. The battery runs under low voltage for a long time, which is a fatal damage; 3 1. Battery charging is a process with high technical content. In order to prolong the service life of the battery, people have studied many charging technologies, but the current situation is that there are many types of batteries, and it is difficult to treat them differently on a charging pile. Battery life, not to mention prolonging life; 4. Battery manufacturers are uneven, and users are individual groups, so it is difficult to optimize battery management and maintenance; Insufficient management awareness and improper disposal are both a waste of resources and pollution to the environment; 6. People lack knowledge of battery use, which may cause safety hazards; 7. Difficult to develop and improve, the battery industry is We are struggling to research and innovate, and new batteries and new types are constantly appearing. However, in this loose and complicated situation, it is difficult to concentrate advantages and improve rapidly. That is to say, battery manufacturers who are willing to innovate at least lack the first-hand information on the use of batteries, let alone many Manufacturers are only satisfied with the status quo and do not know how to make progress, and individuals who use batteries cannot and do not have the ability to study battery innovation and replacement, so this method can only wander in the status quo; 8. It is easy to breed various fake and shoddy products. Ignorance, it is very easy to be deceived when replacing a new battery, and unintentionally replaced with a fake and shoddy product, which has encouraged the development of counterfeit and illegal enterprises; Only increase the energy storage of the battery. One of them is to increase the weight of the battery in order to increase the energy storage. However, increasing the weight of the battery increases the reactive power consumption of energy and reduces the efficiency of the battery.

Generally speaking, at present, an electric vehicle uses a lithium-ion battery with a 60-degree electricity, and the cruising range standard is 300 kilometers, but the dead weight of the battery has reached 600kg, which is 1 / 3 of the weight of the whole vehicle, which is equivalent to carrying 10 A person with a standard weight is considered to be running without a load, and the increase in weight seriously affects the mobility of the car

The second is to develop fast charging. It takes more than three hours to complete the standard charging of the current battery, even the lithium battery, and it is quite difficult to reduce it to less than 20 minutes. At present, the fastest charging is the supercapacitor, but its inherent The low specific energy, large volume, and the performance degradation caused by the difficulty of individual capacitors in series to equalize voltage limit its application.

[0003] To sum up, electric vehicle charging pile charging, although it is the only one in the world, is helpless and the most hopeless. This charging method is bound to affect the popularization and development of the electric vehicle industry. The country has preferential policies, but people are still hesitant and discouraged, which adds a certain degree of difficulty to the control of environmental pollution
