Abstract

The invention discloses a method for monitoring the health state of a low-voltage storage battery of an automobile by using a TBOX, which comprises the following steps: 1) when the low-voltage storage battery is in a health state, the TBOX obtains the voltage working state of each low-voltage component in the automobile, establishes a battery health state model, and calculates the health state of the low-voltage storage battery; the battery health state model comprises a discharge characteristic curve in each scene mode; 2) acquiring working state information of each automobile body low-voltage part in real time, and determining the scene mode of the current automobile; (3) acquiring real-time voltage data of the storage battery in a set time period of the current scene mode, and acquiring a discharge characteristic curve of the storage battery in the current state; and (4) comparing the discharge characteristic curve acquired in the step (3) with the discharge characteristic curve in the health state in the step (1), and judging the health state of the battery according to the difference between the discharge characteristic curve acquired in the step (3) and the discharge characteristic curve in the health state. When the battery is detected, the battery does not need to be disassembled, and monitoring data can be uploaded to the cloud in real time for deep analysis and processing.

Description

technical field [0001] The invention specifically relates to a method for monitoring the health state of an automobile low-voltage storage battery by using a TBOX. Background technique [0002] The on-board low-voltage battery is a very important power supply component in the car. It is a low-voltage DC power supply that can be repeatedly charged and discharged. The vehicle uses an on-board low-voltage battery to supply power to various low-voltage components in the vehicle. The on-board low-voltage battery of a fuel vehicle uses the motor to charge it; while in a new energy vehicle, when the vehicle's high-voltage system is activated, the vehicle charges it through a DC / DC voltage converter. Repeated charging and discharging operations will gradually age the on-board low-voltage battery, causing the plate to vulcanize, and the active material on the surface of the plate will fall off, thereby affecting the power supply capacity of the battery. Therefore, it is very importa...
