Battery pack quick-changing control system for electric automobile

Abstract

The invention discloses a battery pack quick-changing control system for an electric automobile. The battery pack quick-changing control system for the electric automobile comprises a battery pack quick-changing device, a battery manager, a first Hall sensor, a first quick-changing effective sensor, a second quick-changing effective sensor and an automobile controller, wherein the battery pack quick-changing device comprises a battery pack locking mechanism and a tray ejecting mechanism; the automobile controller is respectively connected with the first Hall sensor and the first quick-changing effective sensor so as to obtain a battery pack quick-changing signal and a battery pack locking signal; the automobile controller also communicates with the battery manager; and the automobile controller is used for generating a corresponding control instruction according to the battery pack quick-changing signal, the battery pack locking signal and state information of the electric automobile and transmitting the corresponding control instruction to the battery manager so as to control high voltage power-on or power-off of the electric automobile so that the battery pack quick-changing process is controlled. Through the adoption of the battery pack quick-changing control system for the electric automobile, disclosed by the invention, the battery quick-changing process is monitored and the whole changing process is automatic, the efficiency and safety in the battery pack quick-changing process are improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a battery pack quick-change control system for electric vehicles. Background technique [0002] The development of pure electric vehicles has become more and more important, and some areas already have a certain amount of ownership, including taxis. Pure electric vehicles have many advantages, such as zero emissions, low charging costs and so on. However, due to the constraints of the current battery technology development, the cruising range that can be satisfied by the power of the battery pack is still insufficient, which makes many customers unable to accept electric vehicles. Especially for taxis, it must be guaranteed that they should have the ability to drive 24 hours a day, and neither fast charging nor slow charging can meet this requirement. [0003] The normal operation of the quick change of the high-voltage battery pack of the whole vehicle is carried out...
