Battery monitoring system and method, vehicle and storage medium

Abstract

The invention discloses a battery monitoring system and method, a vehicle and a storage medium, and the system comprises a timing self-checking module, an abnormity self-checking module and a main control module. The timing self-checking module collects battery state information according to the self-checking timing, and determines the next self-checking timing of the timing self-checking module according to the battery state information; the timing self-checking module also notifies the main control module when determining a fault according to the battery state information; the abnormity self-checking module monitors battery state information in real time according to a low-power-consumption operation mode, and notifies the main control module when a fault is determined according to the battery state information; and the main control module is used for receiving notifications of the timing self-checking module and the abnormity self-checking module and waking up the whole vehicle to carry out fault processing. According to the embodiment of the invention, the self-checking period of the timing self-checking module is dynamically adjusted by using the state information, and real-time monitoring is carried out through the low-power-consumption abnormity self-checking module, so that the accuracy of battery state acquisition can be improved, the accuracy of battery state information acquisition is improved, and the risk of battery safety missing report is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of automation control, and in particular to a battery monitoring system, method, vehicle and storage medium. Background technique [0002] In recent years, the market demand for electric vehicles has gradually expanded, and the energy demand for power batteries has also gradually increased. This has higher requirements for the energy density of power batteries. The coverage of safety monitoring functions of power batteries has become an important factor restricting vehicle safety. At present, the safety monitoring of the power battery by the battery management system can cover cycles such as vehicle driving and vehicle charging, but there is a large monitoring blank period when the vehicle is parked and dormant. [0003] In order to improve the coverage of the power battery safety monitoring function, the following technologies are mainly used at present: one is to install sensors s...

Problems solved by technology

However, in the prior art, timing wake-up of the whole vehicle needs to coordinate multiple controllers to complete the monitoring function, which increases the risk of potential function failure, and there is a risk of false or missed report of power battery system failure; adding peripheral sensors not only increases the vehicle manufacturing cost but also increases the risk of failure. Increase the number of vehicle sensors, further increasing the risk of vehicle potential function failure
