Abstract

The invention discloses a vehicle deceleration energy recovery system, at least comprising an energy conversion unit, a DC / DC converter, and an energy recycling controller connected through a first bus. The DC / DC converter is connected with an auxiliary power supply. The first bus is further connected with a storage battery, a starter, and a first load. The DC / DC converter is connected with a second load. Correspondingly, the invention also discloses a vehicle including the deceleration energy recovery system. Using the system can realize recycling and storage of energy when a vehicle reduces speed and brakes, and electric energy is released when necessary, and functions of starting and stopping the starter can be realized through the auxiliary power supply. The system can improve life of storage batteries, and saves oil consumption.

Description

technical field [0001] The invention belongs to the field of energy recovery of automobiles, in particular to an energy recovery system for deceleration of automobiles and a corresponding automobile. Background technique [0002] Automobile braking energy recovery refers to the technology that converts a part of mechanical energy (kinetic energy) into other forms of energy when the vehicle is decelerating or braking, and then utilizes it. The basic principle is to convert or transfer a part of the mechanical energy (kinetic energy) of the vehicle into other forms of energy through the recovery system and store it in the energy storage unit, and at the same time generate a certain load resistance to slow down or brake the vehicle. When the vehicle starts or accelerates again, the system converts the energy stored in the energy storage unit into the kinetic energy or electric energy required for the vehicle to drive, thereby achieving the purpose of reducing fuel consumption. ...
