Problems solved by technology

[0004] At present, the voltage and current acquisition accuracy of the electric vehicle battery management system restricts the battery pack power estimation accuracy, and the voltage acquisition accuracy restricts the battery pack energy estimation accuracy. Excessive temperature indicates potential safety hazards caused by loose battery connections due to vibration and other issues. , which will inevitably increase the error rate of battery management decisions, so it is urgent to develop and design a high-precision, portable power battery pack monitoring system

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a novel high-speed electric vehicle battery management system. Background technique [0002] The 21st century has entered an important era of new energy development. With the rapid development of science and technology, the development of new energy has gradually occupied the mainstream position of energy development. Especially in the case of increasingly fierce international energy competition and national defense, new energy The role of it is very important, especially the rapid development of the automobile industry today, and the use of traditional oil as power has brought about major problems such as oil energy shortages and environmental pollution. In recent years, with the vigorous development of the automotive industry powered by lead-acid batteries, online monitoring of battery packs, battery work safety alarms and estimation of battery remaining power are par...
