Abstract

The invention discloses a power battery monitoring system and a vehicle. The power battery monitoring system comprises a power battery management system, the power battery management system comprises an acquisition board and a main control board, the main control board comprises a controller and a converter, the controller is connected with the converter, and the converter is connected with the acquisition board; the acquisition board is independently powered by the power battery, can continuously monitor the voltage and the temperature of the power battery, and feeds back a fault signal to the converter when the voltage and / or the temperature are / is abnormal; when the converter receives the fault signal, if the power battery management system is in a sleep mode, the converter is automatically awakened firstly, and then the controller is awakened to enter an operation mode, so that the controller executes a corresponding fault diagnosis action according to the fault signal. According to the invention, continuous safety monitoring of the power battery is realized in the sleep mode, the safety risk of the battery is reduced, a wake-up function does not need to be set, dark current consumed during working is very low, and additional hardware cost does not need to be increased.

Description

technical field [0001] The invention relates to the technical field of vehicle battery management, in particular to a power battery monitoring system and a vehicle. Background technique [0002] Power battery is an indispensable and important component of new energy vehicles, and battery safety is one of the core issues of power battery application. As the control unit of the power battery, the battery management system (BMS) undoubtedly needs to undertake important functions such as safety monitoring, troubleshooting and alarming of the power battery. Among them, safety monitoring is the premise of fault processing and alarming. Only when the abnormality of the power battery is monitored can the next fault processing and alarming be carried out. Since the abnormality of the power battery is often reflected in the abnormality of two important parameters, the battery voltage and the battery temperature, safety monitoring is usually achieved by monitoring the battery voltage ...
