Abstract

The invention relates to a battery replacement fault diagnosis method and system. Among them, the method includes: making the preliminary positioning of the vehicle and judging whether the preliminary positioning of the vehicle has been completed; Unlocking position; use the battery unlocking strategy to unlock the battery and determine whether the battery unlocking has been completed; move the tram to the transfer position and determine whether the battery transfer has been completed; move the tram to the locking position and determine whether the tram has moved to the add Lock position; use the battery locking strategy to lock the battery and determine whether the battery locking has been completed; move the tram to the handover position and determine whether the tram has moved to the handover position; move the hoist to the initial position and judge the hoist Whether it has moved to the initial position; where, when it is judged that a fault has occurred, a warning signal is issued and the previous step is returned.

Description

technical field [0001] The invention relates to the field of control methods and systems. More specifically, the present invention relates to a battery replacement fault diagnosis method for electric vehicles, which is used to detect and report faults during the process of replacing a power battery of the vehicle. The invention also relates to a battery replacement fault diagnosis system for an electric vehicle. Background technique [0002] Electric vehicles generally use batteries to provide power. However, existing battery technology defects hinder the large-scale popularization of electric vehicles, the main problem of which comes from battery life. Conventional systems that run on gasoline typically only take a few minutes to top up at a gas station, while electric vehicles can take hours to recharge. Due to the battery life problem, electric vehicles need to be charged more frequently, so waiting for a long time to charge the battery seriously affects the user exper...
