The invention provides a battery management system for an electric automobile. The battery management system comprises an information input module, a battery management module and a battery management module, wherein the information input module is used for inputting destination information of a journey by a user before the electric automobile departs; the electric quantity detection module is used for detecting the electric quantity of the electric vehicle in real time; a primary path planning module for performing primary path planning based on the destination information to obtain a first path; the estimation module is used for estimating whether the destination can be reached before the electric quantity is used up or not based on the first path and the detected electric quantity; and if the pre-estimation module pre-estimates that the destination cannot be reached before the electric quantity is used up, the secondary path planning module searches each battery swap station on the way according to the first path, and selects one battery swap station on the way as an intermediate destination to carry out secondary path planning. The invention provides a battery management method for an electric vehicle and the electric vehicle.
Description
technical field [0001] The present invention relates to a battery management system for an electric vehicle, a battery management method, and an electric vehicle having the battery management system. Background technique [0002] In recent years, with the depletion of petroleum resources and the increasingly serious environmental pollution, the utilization rate of electric vehicles has been increasing. However, compared with the penetration rate and acceptance rate of fuel vehicles, electric vehicles are still far behind. [0003] The reason is that the existing electric vehicles have insufficient battery life and long charging time. [0004] In order to solve this problem, the concept of a shared battery system for electric vehicles has been proposed. The shared battery system of electric vehicles includes electric vehicles, shared batteries and swap stations. The electric vehicles do not include shared batteries when purchased, but are leased. It is provided for electric...
