Problems solved by technology

Normally, after the vehicle is turned off, the battery management system is turned off and will not be able to monitor the battery status
Since the battery status information cannot be obtained during the shutdown period, that is, the battery status cannot be monitored, and the battery cannot be protected during the shutdown period.
When the vehicle is powered on again, it is impossible to accurately estimate the state of the power battery because the battery information during the shutdown period cannot be known.

Abstract

The invention provides a monitoring system of a power battery. The monitoring system comprises a master control panel and a plurality of controlled panels, wherein the controlled panels are separately arranged in a plurality of battery modules in one-to-one correspondence manner; when entering an off-line monitoring mode, the controlled panels monitor the corresponding battery modules, and activate the master control panel and report failure information to the master control panel when monitoring that a failure occurs to the corresponding battery module; and the master control panel is used for controlling the controlled panels to enter the off-line monitoring mode when a vehicle is closed, and performing comprehensive failure diagnosis and failure treatment on the power battery according to the failure information after being activated by the controlled panels. According to the monitoring system disclosed by the invention, the power battery can be detected when the vehicle is closed, so that the power battery is effectively protected in real time; and besides, the controlled panels record the battery condition information when the master control panel is off-line, and after the master control panel is activated, report the battery condition information to the master control panel for performing SOC estimating, SOH estimating and the like. The invention further discloses a control method for the monitoring system of the power battery, as the vehicle.

Description

technical field [0001] The invention relates to the technical field of battery performance monitoring, in particular to a monitoring system, a control method and a vehicle of a power battery. Background technique [0002] The power battery of an electric vehicle needs to be managed and monitored by a battery management system. Normally, after the vehicle is turned off, the battery management system is turned off and will not be able to monitor the battery status. Since the battery status information cannot be obtained during the shutdown period, that is, the battery status cannot be monitored, and the battery cannot be protected during the shutdown period. When the vehicle is powered on again, it is impossible to accurately estimate the state of the power battery because the battery information during the shutdown period cannot be known. Contents of the invention [0003] The present invention aims to solve at least one of the above-mentioned technical problems. [0004...
