Description

technical field [0001] The invention relates to the technical field of battery charge and discharge, in particular to an efficient management and control system for charge and discharge of electric vehicle batteries. Background technique [0002] Due to the increasing environmental pollution and the shortage of fossil fuels such as oil, the technology of pure electric vehicles has developed rapidly. Lithium-ion batteries have been widely used as power sources for pure electric vehicles due to their high capacity density, high cell voltage, and high-performance-price ratio. But for pure electric vehicles, it is very important to monitor the battery charging and discharging process, various operating parameters, and the location tracking of electric vehicles, and it can also improve the safety of electric vehicles. [0003] At present, many electric vehicles use lithium batteries as backup batteries. The service life of lithium batteries has a greater relationship with the nu...

Problems solved by technology

However, most portable devices do not control the charging of the lithium battery. For example, when the power adapter is connected to an external AC power, the lithium battery will automatically charge, and the power of the lithium battery at this time is likely to be sufficient to maintain the operation of the portable device. For quite a long time, this may reduce the service life of the battery due to the increase in the number of charging of the lithium battery

[0004] The electric vehicle battery charging and discharging system in the prior art cannot adjust the charging and discharging parameters of the battery according to the load or the performance of the battery. Sequential charge and discharge greatly affects the service life and the number of charge and discharge of the battery, and it cannot be protected in time if there is an abnormal situation
