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, e...

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.

[0007] The 60-degree lithium-ion battery is used, and the mileage standard is 300 kilometers, but the weight of the battery has reached 600kg, which is 1 / 3 of the weight of the whole vehicle, which is equivalent to carrying 10 people with a standard weight on the road. , the increase in weight seriously affects the maneuverability 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.

[0008] 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
