Description

technical field [0001] The invention relates to a power supply management system, in particular to a vehicle-used high-efficiency power supply intelligent management system. Background technique [0002] Due to the increasing shortage of petroleum resources used by internal combustion engine vehicles, coupled with the disadvantages of emitting greenhouse gases such as carbon dioxide, dust particles, and making noise, electric vehicles are very quiet, do not emit dust particles, and have zero greenhouse gas emissions. Requirements and many other advantages are gradually favored by people. With the emphasis on the environment, electric vehicles have attracted more and more attention as a non-polluting means of transportation, and have a good development prospect. The development of electric vehicles and related technologies has become a topic of great strategic significance for the development of science and technology industries in various industrial countries. my country ha...

Problems solved by technology

[0003] At present, there are mainly four types of power batteries for electric vehicles: lead-acid batteries, nickel-metal hydride batteries, nickel-cadmium batteries and lithium batteries. Because lithium batteries have the advantages of high working voltage, large specific energy, long cycle life, and no pollution, they are the best choice for electric vehicles. The main direction of development, but the biggest disadvantage of lithium batteries is that the safety is worse than that of authorized batteries, nickel-metal hydride batteries and nickel-cadmium batteries. Due to differences in manufacturing processes, the characteristics of each single lithium battery cannot be completely consistent. After working for a period of time, the difference will become more obvious, so there may be an unbalanced phenomenon when charging and discharging, that is, some batteries reach the upper limit voltage when charging, and some batteries have not yet reached the upper limit voltage. When the battery exceeds its upper limit voltage, when it reaches a certain level or exceeds the specified range due to overheating or other abnormal physical and chemical properties, an explosion accident will occur. In this way, each single battery must be tested, shunted and balanced, that is to say, electric The battery of the car must have a feasible and reliable vehicle power management system to improve the energy efficiency and service life of the power battery

[0004] However, most of the existing electric vehicle power management systems have disadvantages such as complex and large systems, poor reliability, and unfavorable network communication.

In addition, the secondary charging time of the electric vehicle power supply should not be too long. In order to reduce the charging and discharging time of the battery, a high-current charging and discharging method is generally used, but this will easily cause the performance of the battery to decrease or even be damaged, resulting in some unsafe hidden dangers. Therefore There is an urgent need to further improve the existing electric vehicle power management system
