Embodiment Construction

[0013] In order to make the above and other objects, features, and advantages of the present invention more obvious, the following will be described in detail with the accompanying drawings.

[0014] figure 1 It is a structural diagram of the regenerative braking energy recovery system provided by the present invention, such as figure 1 As shown, the present invention provides a regenerative braking energy recovery system for a vehicle. The vehicle includes an on-board battery. The system includes a vehicle controller 40 and an energy recovery ratio electrically connected to the vehicle controller 40. The adjustment device 10, the vehicle speed sensor 20, and the battery management system 30.

[0015] The energy recovery ratio adjusting device 10 can set an energy recovery ratio, which can be any ratio between 0% and 100%, for example, where 0% means that the regenerative braking energy recovery system is disabled and only the traditional Braking method; 100% means maximum use of e...

Abstract

The invention discloses a system for recovery of regenerative braking energy of a vehicle and a method thereof. The vehicle comprises an on-board battery. The system comprises an energy recovery ratio adjusting device, a speed sensor, a battery management system and a whole vehicle controller, wherein the energy recovery ratio adjusting device is used for setting an energy recovery ratio; the speed sensor is used for detecting the current speed of a vehicle; the battery management system is used for determining the current carrying capacity of the onboard battery; and the whole vehicle controller is electrically connected with the energy recovery ratio adjusting device, the speed sensor and the battery management system, and is used for calculating the expected regenerative braking generation power according to the energy recovery ratio, the current speed and the current carrying capacity, and adjusting a motor according to the expected regenerative braking generation power, so that the difference between the actual regenerative braking generation power generated by the motor and the expected regenerative braking generation power is within a preset range. The invention can provide multiple choices for the driver, so that the driver can select different energy recovery ratios according to the driving habits, thereby not only ensuring the full recovery of energy, but also avoiding the loss of vehicle safety.

Description

Technical field [0001] The present invention relates to the fields of hybrid vehicles, pure electric vehicles and fuel cell vehicles, and in particular to a regenerative braking energy recovery system and method for vehicles. Background technique [0002] Both oil and natural gas are non-renewable resources, and how to save energy is an urgent matter. Hybrid vehicles, pure electric vehicles, and fuel cell vehicles, which are one of low-carbon technologies, are the development trends and hot spots in the 21st century. These vehicles are equipped with on-board batteries, and the electric motors on the vehicles can use the energy stored in the vehicle batteries to drive the vehicle. [0003] In order to further improve energy utilization, the vehicle is usually equipped with a regenerative braking energy recovery system. This system can switch the motor on the vehicle to zero when the accelerator opening of the vehicle is zero (that is, when the driver releases the accelerator) The ...
