Abstract

The invention provides a monitoring method of a power battery. The method includes the following steps that whether an electric automobile is in a flameout parking state or not is judged; if the electric automobile is in the flameout parking state, an automobile-mounted terminal is controlled to enter in a dormant state, and a timing module starts to conduct timing; when the timed time reaches first preset time, the automobile-mounted terminal and a battery management system are awakened to enter in a working state, and the timing module is controlled to restart conducting timing; the batterymanagement system enters in the working state, starts to monitor battery state information of the power battery and sends the battery state information to a monitoring platform through a communicationmodule; and when the re-timed time reaches second preset time, the battery management system is controlled to stop working and enter in a dormant state, and whether the electric automobile is in theflameout parking state or not is judged again. By the adoption of the provided monitoring method of the power battery, potential safety hazards of the power battery in the flameout parking state of the automobile can be eliminated. The invention further provides the electric automobile.

Description

【Technical field】 [0001] The invention relates to the technical field of electric vehicles, in particular to a monitoring method for electric vehicles and power batteries thereof. 【Background technique】 [0002] Existing pure electric vehicles only monitor the battery status information of the power battery when the vehicle is running and charging, and send the battery status information of the power battery to the remote monitoring platform through the vehicle terminal (T-BOX). The battery status information of the power battery is not monitored when the vehicle is turned off. However, when the pure electric vehicle is turned off and placed, the power battery also suffers from power loss, single battery failure, or fire caused by a short circuit, and the above situations are often brought to the power battery due to failure to detect and take treatment measures in time. Serious damage, or even serious safety accidents. [0003] In view of this, it is necessary to provide ...
