The invention relates to the technical field of an intelligent power system of an electric vehicle, and provides an intelligent control method and device of the electric vehicle, a power system and the electric vehicle. The method comprises the steps of receiving voltage information of each single battery in a modular battery corresponding to a slave battery management unit, temperature information of the modular battery and current information of the modular battery, which are sent from the slave battery management unit; judging a running state of the modular battery; sending a starting instruction to the slave battery management unit if the running state of the modular battery is normal; and sending a disconnection instruction to the slave battery management unit if the running state ofthe modular battery is abnormal. By the method, the device, the power system and the electric vehicle, the problem that the running state of the modular battery cannot be effectively detected by the prior art to cause that the safety running of the whole electric vehicle cannot be effectively guaranteed can be solved.
Description
technical field [0001] The invention relates to the technical field of electric vehicle intelligent power system, in particular to an electric vehicle intelligent control method, device, power system and electric vehicle. Background technique [0002] The electric vehicle battery management system is an important link connecting the vehicle power battery and the electric vehicle. Its main functions include: real-time monitoring of battery physical parameters, battery state estimation, online diagnosis and early warning, charge, discharge and pre-charge control, balance management and thermal management etc., the existing battery pack control efficiency is low, resulting in a decline in the overall performance of the battery management system. Therefore, in the prior art, the operating state of the module battery cannot be effectively detected, so that the safe operation of the entire electric vehicle cannot be effectively guaranteed.
