Abstract

The application relates to the technical field of range extenders, in particular to a range extender control method and device, equipment and a storage medium. The method comprises the following steps: acquiring electric quantity information of a battery; determining a first preset power of a range extender according to the electric quantity information; acquiring the current power information ofthe vehicle; determining a second preset power of the range extender according to the power information; acquiring the change rate of an accelerator pedal within a preset duration; determining a thirdpreset power of the range extender according to the change rate; and determining the output power of the range extender according to the first preset power, the second preset power and the third preset power. The power of the range extender is controlled by adopting three logics, so that the requirements of economy and dynamic property of a vehicle are met, and the balance of the economy and thedynamic property is achieved.

Description

technical field [0001] The present application relates to the technical field of range extenders, in particular to a control method, device, equipment and storage medium for a range extender. Background technique [0002] With the intensification of energy shortage and the gradual enhancement of people's awareness of environmental protection, new energy vehicles are currently developing rapidly. The characteristics of zero fuel consumption and zero emission of new energy vehicles make them ideal clean energy vehicles. However, limited by the constraints of battery technology, power batteries have many problems such as low energy density, large volume and mass, long charging time, high use and post-maintenance costs. Before a major breakthrough in battery technology, a suitable power form is needed to realize the transition from traditional vehicles to pure electric vehicles, and plug-in extended-range electric vehicles have emerged as the times require. The electrical stru...
