Braking energy recovery device and system for pure electric automobile

Abstract

The invention discloses a braking energy recovery device and system for a pure electric automobile. The device comprises a box body and a motor, wherein the left side of the bottom of an inner cavityof the box body is fixedly connected with a composite energy storage system, and the right side of the bottom of the inner cavity of the box body is fixedly connected with an execution mechanism; theright side of the inner cavity of the box body is fixedly connected with a first efficiency calculation module and a second efficiency calculation module; the top of the inner cavity of the box body is fixedly connected with a logic module; and the part, on the left side of the logic module, of the top of the inner cavity of the box body is fixedly connected with a required power generation module. According to the device and system, the effect of placing electric equipment is achieved by arranging the box body, the effect of energy storage is achieved through the composite energy storage system, the effect of controlling input and output power of a storage battery and input and output power of a super capacitor is achieved through the execution mechanism, the electric automobile can reasonably distribute energy through the first efficiency calculation module and the second efficiency calculation module, and the driving range of the pure electric automobile can be prolonged.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a braking energy recovery device and system for pure electric vehicles. Background technique [0002] An electric vehicle refers to a vehicle that is driven by a vehicle-mounted power supply and driven by a motor to drive the wheels, and meets the requirements of road traffic and safety regulations. Devices, etc. When pure electric vehicles are running on the road, due to frequent starting, acceleration and braking, etc., they will consume a lot of energy, and the driving range will be significantly shortened, which seriously limits the use of pure electric vehicles. The car cannot reasonably adjust the energy distribution of the car, and it is also unable to extend the mileage of the pure electric vehicle. Therefore, we propose a pure electric vehicle braking energy recovery device and system. Contents of the invention [0003] The purpose of the present invention i...
