Constant current control method, device and vehicle

Abstract

The application provides a constant current control method and device and a vehicle. The constant current control method obtains an initial parameter value of a target control device from target parameter values corresponding to different candidate loads based on a current load when a load of a constant current system changes, and updates a current parameter value of the target control device based on the initial parameter value and a target current value and a current value of the constant current system until a difference between the current value and the target current value meets a preset threshold interval. Since the initial parameter value of the target control device is obtained from the target parameter values corresponding to the different candidate loads based on the current load, the initial parameter value of the target control device can be close to the target parameter value, so that in the process of updating the parameter values of the control parameters of the target control device based on the initial parameter value, the constant current output response time of the constant current system can be effectively reduced, and the applicability to different application scenarios is improved.
