Abstract

The invention provides a power battery information monitoring method and device and an electric vehicle, and relates to the technical field of electric vehicles, and the power battery information monitoring method comprises the steps of obtaining the working mode of a target power battery; the working mode comprises a driving mode, a battery swap station charging mode or a battery swap station monitoring mode; and according to the working mode of the target power battery, sending battery information to a battery replacement controller or a battery replacement station charger. According to the method, different monitoring modes are provided for the power batteries in different working modes, the safety risk of the battery swap station can be prejudged in advance, the risk of replacing a faulty battery is reduced, and the battery replacing time is shortened.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a method and device for monitoring power battery information and an electric vehicle. Background technique [0002] The electric vehicle battery replacement system refers to the centralized storage and charging of a large number of battery systems through the battery exchange station. Users can replace the battery system of electric vehicles in 1 minute or even less time, which solves the problem of long charging time of the battery system. The traditional working mode of the substation is as follows: figure 1 As shown, each battery system corresponds to a charger, and the battery replacement station can only receive battery information when the battery system is charging. The power station cannot know the voltage, temperature, insulation resistance and a series of fault information in the battery system, which is not conducive to the information collection...
