Problems solved by technology
However, in the prior art, there are few studies on this aspect
Therefore, on the one hand, the driver cannot immediately grasp the overall operating status of the battery pack; on the other hand, when the battery pack fails or needs maintenance, the maintenance personnel cannot obtain the historical state information of the battery, and cannot quickly and accurately find the fault reason

The invention discloses an electric vehicle battery management system with a system evaluating function. The electric vehicle battery management system comprises a real-time evaluating module and a historic evaluating module, wherein the real-time evaluating module is used for evaluating a battery on the basis of system evaluating algorithm according to battery data acquired in real time and storing the acquired data of the battery after preprocessing, and the historic evaluating module is used for evaluating the battery on the basis of the system evaluating algorithm according to the stored data of the battery. By adopting the technical scheme of the electric vehicle battery management system, operating states of battery points can be acquired in real time, and historic state information of the battery can be acquired during maintenance for breakdown.
Description
technical field [0001] The invention relates to the technical field of battery management, in particular to an electric vehicle battery management system with a system evaluation function. Background technique [0002] Under the requirements of the era of low-carbon and environmental protection, electric vehicles have emerged as a new energy vehicle, and lithium-ion batteries, as their most promising power source, have attracted widespread attention. Although lithium-ion batteries have excellent performance, it is inevitable that various problems will occur when using batteries as the main power source, such as heat accumulation inside the battery, barrel effect of the battery pack, etc. These problems not only affect the normal operation and life of the battery, but also have an impact on the safety of the car, and even cause safety problems in severe cases. [0003] Using the battery management system to timely feed back the fault information of the battery during operati...
