Abstract

The invention provides a battery monitoring method and device applied to a vehicle, and equipment. The method comprises the following steps: obtaining a first current value and a second current valueof a battery at a current moment and a terminal voltage and an open-circuit voltage at the current moment, wherein the first current value and the second current value to be collected by different current collection units; determining a third current value according to the terminal voltage and the open-circuit voltage of the battery at the current moment; and determining an effective current valueof the battery according to the first current value, the second current value and the third current value, and monitoring the operation of the battery according to the effective current value. According to the method, the effectiveness of the current acquisition unit can be effectively judged, the effective current value is obtained, the operation of the battery is monitored according to the obtained effective current value, and the situation that the battery cannot be effectively monitored when the current acquisition unit breaks down is avoided.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a battery monitoring method, device and equipment applied to vehicles. Background technique [0002] A vehicle is an important tool for people to travel. A battery can be installed in the vehicle, and the battery provides power for the vehicle or other energy needs. During the working process of the battery, in order to avoid damage to the battery due to excessive current, or the vehicle cannot run normally due to too low current, it is necessary to monitor the battery current. [0003] At present, when monitoring the current of the battery, a battery acquisition unit can be installed on the main circuit outside the battery, and the main circuit current can be collected through the battery acquisition unit to ensure that the battery works in a normal state to ensure the safety of the battery. [0004] However, in the actual monitoring process, when there is a drift...
