Abstract

The invention provides a recycling and distributing method and system for regenerated braking energy and a vehicle.The regenerated braking energy is recycled to an energy storage system.The energy storage system comprises multiple energy storage units.The method includes the steps that 1, the distribution ratio k of the energy stored and recycled in all the energy storage units in the energy storage system is set; 2, data relevant to braking within a period of time is acquired; 3, a mathematical expected number of the data in the step 2 is calculated; 4, the relation between the mathematical expected number in the step 3 and a set value is judged, and the distribution ratio k is adjusted.The distribution ratio of the energy recycled in the all energy storage units in the energy storage system is adjusted according to the braking information data acquired when the vehicle runs for a period of time, and the energy is utilized completely.

Description

technical field [0001] The invention relates to vehicle control technology, especially a method for distributing recovered energy in a vehicle with a regenerative braking energy recovery system, the regenerative braking energy recovery system and an electric vehicle using the system. Background technique [0002] One of the most important components in an electric vehicle is the battery. The amount of electricity stored in the battery determines the cruising range of the vehicle. At present, the storage battery is still the bottleneck that cannot be broken through in the development of electric vehicles, and the mileage of electric vehicles still cannot meet people's needs. The braking energy regeneration system can regenerate the energy generated by braking to the energy storage system. Its basic principle is to realize the conversion of electric energy and vehicle kinetic energy through a generator / motor with reversible action. When the car brakes or decelerates, the gen...
