Battery state monitoring method and monitoring device

Abstract

The invention discloses a battery state monitoring method. The battery state monitoring method includes collecting battery information and calculating out battery remaining capacity according to the battery information; transmitting the battery information and the battery remaining capacity to a remote monitoring and managing server; and receiving a control instruction which is sent by the remote monitoring and managing server and used for revising the battery remaining capacity. The control instruction includes using an accurate value of the battery remaining capacity to replace battery remaining capacity data which are obtained through initial calculation so as to update the data, accordingly, the accurate value of the battery remaining capacity is obtained, then, charging and discharging are performed, the fact that each charging and discharging exceeds a preset range is unlikely, and a battery is protected. The invention further discloses a battery state monitoring device.

Description

technical field [0001] The invention relates to the field of automatic control of pure electric vehicles, and more specifically, to a battery state monitoring method and monitoring equipment. Background technique [0002] With the development of pure electric vehicle technology, the number of pure electric vehicles on the market is increasing day by day, and people are paying more and more attention to pure electric vehicles. Although pure electric vehicle technology has developed to a certain extent, there are still many problems, among which the issue of pure electric vehicle power batteries has attracted the most attention. [0003] At present, when the on-board battery management system inside a pure electric vehicle calculates the remaining power with a prescribed algorithm, it will generate an error value every time and record it in the management system. The calculation is inaccurate, resulting in a large deviation between the remaining power of the battery calculate...

[0003] At present, when the on-board battery management system inside a pure electric vehicle calculates the remaining power with a prescribed algorithm, it will generate an error value every time and record it in the management system. The calculation is inaccurate, resulting in a large deviation between the remaining battery power calculated by the on-board battery management system and the actual value, so that when the battery is charged and discharged, the phenomenon of overcharging and overdischarging will occur, which will damage the battery
