Abstract

The invention discloses a power-on method of a battery system, the battery system and a readable storage medium. The method comprises the following steps: receiving working state data of all battery packs; judging whether the working state of the battery pack is normal or not according to the working state data; if the judgment result is that the working state of the battery pack is normal, obtaining the number of the battery packs in the battery system; and determining a corresponding power-on strategy according to the number of the battery packs, and controlling the battery packs to be powered on according to the power-on strategy. According to the invention, the circulating current problem when the parallel battery pack is electrified can be solved, and the service life of the battery pack is prolonged.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a battery system power-on method, the battery system and a readable storage medium. Background technique [0002] In electric vehicles, the power battery is used to provide electric energy to drive the vehicle to move. The current electric vehicle market is becoming more and more diverse, and customers have different mileage requirements. In order to meet the needs of customers, it is required to develop battery packs with multiple power levels for the same model. , for users to choose different battery packs according to their own needs. At present, through the realization of parallel battery pack technology, battery packs with multiple capacities are developed at the same time. The existing parallel battery pack technology is directly connected in parallel through multiple battery packs. The disadvantage of this solution is that there is a circulation problem when t...
