Abstract
The utility model relates to an energy recovery system of a hybrid electric vehicle. The energy recovery system comprises a whole vehicle controller; the whole vehicle controller respectively controls and is connected with a main motor controller, a main motor, an accumulator management system, an accumulator and a direct current/direct current (DC/DC); the output end of the DC/DC is connected to the charging end of a whole vehicle low-voltage power supply; the main motor is respectively connected with the accumulator and the DC/DC; when the system runs, the whole vehicle controller judges the running state of the vehicle, and sends instructions to the main motor controller and the accumulator management system to control the main motor to be used for driving or generating power; when the main motor is used for generating the power, energy is first supplied to the accumulator; and when the accumulator is full of the power, the whole vehicle low-voltage power supply is charged through the DC/DC. The system can improve the continuous energy recovery efficiency and the braking safety.
Description
Technical field
The utility model belongs to technical field of hybrid power, relates to a kind of hybrid vehicle braking or descending energy-recuperation system.
Background technology
Along with closing on of new-energy automobile industrialization, increasing automotive supplier is spending huge man power and material on new-energy automobile.Hybrid vehicle not only has new forms of energy and comes the technical characterstic that source range is wide, economic benefit is high; Can also when car brakeing deceleration or descending, realize energy supply through energy-recuperation system, energy-recuperation system comprises entire car controller, and this entire car controller control linkage respectively has main electric machine controller and main motor, accumulator management system and accumulator; Main motor both can be used as powered vehicle and had gone; Also can be used as braking energy and reclaim, its concrete way of recycling is when car retardation braking or descending, and main motor is switched to power generation mode; Motor is in auxiliary braking; Kinetic energy is converted into electric energy and is stored in the accumulator,, increase the travelled distance of car load to improve the energy utilization efficiency of car load.But, if accumulator stores full the time, system will be not recuperated energy again, will cause the efficient of system recoveries energy not high like this, and when being unfavorable for glancing impact or descending the driver to the control of vehicle.
The utility model content
The purpose of the utility model provides a kind of hybrid vehicle energy-recuperation system, and is not high with the efficient that solves the existing system recuperated energy, and when being unfavorable for glancing impact or descending the driver to the problem of the control of vehicle.
Entire car controller: be the core control part of hybrid vehicle, be responsible for gathering information such as acceleration pedal signal, brake pedal signal, electric quantity signal, vehicle-state output command after logical calculated and give each Parts Controller to control the action of each parts.
Main electric machine controller: be the function unit of hybrid vehicle, receive the instruction control master's motor-driven or the brake power generating of entire car controller, and the status information of main motor is fed back to entire car controller.
DC/DC: be meant that with a fixing dc voltage conversion be variable vdc; This technology is widely used in the stepless change and the control of trackless trolley car, subway train, battery-driven car; Make above-mentioned control obtain the performance of quickening steadily, responding fast simultaneously, and receive the effect of saves energy simultaneously.But replace rheostat saves energy (20 ~ 30) % with DC chopper.DC chopper can not only play pressure regulation (Switching Power Supply), can also play the effect that suppresses grid side harmonic current noise effectively simultaneously.
A kind of hybrid vehicle energy-recuperation system of the utility model; Comprise entire car controller; This entire car controller control linkage respectively has main electric machine controller and main motor, accumulator management system and accumulator; Said entire car controller also control linkage has DC/DC, and the mouth of this DC/DC is connected into the charging end of car load low potential source, and said main motor links to each other with DC/DC with accumulator respectively.
Further, said car load low potential source is all power supplys except that high-voltage energy storage device.
In the hybrid vehicle energy-recuperation system of the utility model, vehicle control unit controls is connected with DC/DC, and main motor can be given the charging of car load low potential source through this DC/DC.When system moves; Entire car controller judges vehicle running state, sends instructions to main electric machine controller and accumulator management system, controls main motor and be used for driving or being used for generating, when main motor is used for generating electricity; Give the accumulator makeup energy earlier; When accumulator is full of electricity, give the charging of car load low potential source through DC/DC, this system can improve the efficient of lasting recuperated energy and the safety of braking.
Description of drawings
Fig. 1 is the energy-recuperation system structural representation of the utility model;
Fig. 2 is the energy-recuperation system control line schematic diagram of the utility model;
Fig. 3 is the workflow diagram of the energy-recuperation system of the utility model.
The specific embodiment
As shown in Figure 1, hybrid vehicle energy-recuperation system structure mainly comprises entire car controller, main electric machine controller, main motor, accumulator management system BMS, accumulator, DC/DC, low potential source etc.Vehicle control unit controls is connected with main electric machine controller and main motor; Entire car controller is control linkage accumulator management system BMS and accumulator also; Entire car controller also control linkage has DC/DC; The mouth of this DC/DC is connected into the charging end of car load low potential source, and main motor links to each other with DC/DC with accumulator respectively.Like Fig. 2, shown in 3, brake pedal sends brake pedal aperture signal to entire car controller; Das Gaspedal is sent throttle signal to entire car controller; Main electric machine controller receives the mode of operation that main motor sends, and sends main electric machine operation state to entire car controller, and the work order that receives entire car controller is to control main this instruction of motor response; The accumulator management system is controlled to charging accumulator; Electrical generator charges to low potential source through DC/DC.
Concrete working process:
Process one: when entire car controller detected the ability recuperated energy, when the electric weight in the accumulator was discontented, entire car controller sent instructions and gets into power generation mode to main motor controller controls master's motor; Give charging accumulator; Be full of up to accumulator,, then get into process two if also have energy demand to reclaim;
Process two: when accumulator is full of; Entire car controller sends instruction and gives main motor controller controls master's electric power generation; Give the charging of car load low potential source through DC/DC, can improve the efficient of energy recovery widely like this, can keep the conformability and the safety of braking again.
Claims (2)
1. hybrid vehicle energy-recuperation system; Comprise entire car controller; This entire car controller control linkage respectively has main electric machine controller and main motor, accumulator management system and accumulator; It is characterized in that: said entire car controller also control linkage has DC/DC, and the mouth of this DC/DC is connected into the charging end of car load low potential source, and said main motor links to each other with DC/DC with accumulator respectively.
