Abstract

The invention provides a current collection method of a vehicle and a device thereof, control equipment and an automobile, and the current collection method comprises the steps: obtaining the feature information of all channels capable of collecting current signals; performing priority ranking on the channels according to the feature information; determining a target channel according to a sorting result; and outputting a current signal collected from the target channel. According to the scheme, the current information inside and outside the BMS is fully utilized, and the current information is fully verified, so that the robustness of current signal acquisition is effectively ensured, the configuration is convenient, and the reliability is high.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a vehicle current acquisition method, device, control equipment and automobile. Background technique [0002] Electric vehicles are a new direction for the future development of automobiles, and the battery management system (Battery Management System, referred to as BMS) is a key component of the core technology of electric vehicles. [0003] In the battery management system technology of electric vehicles, current data acquisition is a crucial part. The reliability of current data acquisition and calculation will directly affect the accuracy of battery State of Charge (SOC) estimation and continuous driving. The accuracy of mileage can even affect the safety of electric vehicles. In other words, the accuracy of current data collection and calculation and fault diagnosis will directly affect the performance of electric vehicles. [0004] At present, there are at least the following ...
