Description
Technical field
The invention belongs to battery boosting technology fields, and in particular to a kind of vehicle and its battery charging control method, system.
Background technique
It is continued to develop recently as economy, vehicle population increases rapidly, currently, for new energy pure electric automobile
Relatively broad popularization has been obtained in energy recycling system, but is directed to the energy when work of hybrid vehicle traditional combustion engine
It is fewer and fewer to measure recovery system.Generally in internal combustion engine part, when vehicle deceleration, braking, the kinergety of vehicle passes through braking
System is changed into thermal energy, and discharges into the atmosphere, and on the one hand causes the waste of very big energy, on the other hand causes greatly to environment
Pollution.To avoid energy waste, improving the fuel economy of hybrid vehicle while reducing hybrid vehicle tradition
Internal combustion engine to environment pollute it is a kind of for internal combustion engine traditional on hybrid vehicle when energy recycling system just become
Extremely urgent demand.
Has the design scheme of many related automobile energy recycling in the prior art, such as Chinese invention patent Authorization Notice No.

The purpose to recover energy.
Specifically, a kind of control method of automobile conventional part energy regenerating the following steps are included:
When S1, vehicle normally go up electricity operation and battery SOC (State of Charge) value less than 30%, instrument is carried out
Sound, light, electric alarm remind driver's accumulator electric-quantity insufficient, and driver selects " 1 " shelves, and energy regenerating integrated manipulator starts work
Make, when detect gas pedal aperture from large to small and brake pedal aperture change from small to big change when, controller to energy return
It receives clutch and generator sends work order；
S2, as shown in Fig. 3 hybrid vehicle conventional part energy recycling system structural schematic diagram, when energy regenerating clutch
When device 9 receives work order, clutch electronic control unit 5 controls hold-down mechanism 6 and works, and then makes secondary part 4 and active part 3
Engagement achievees the purpose that engine 1 is coaxial with forwarding electricity with generator 8, directly so that driving shaft 2 drives driven shaft 7 to rotate at this time
To the full electricity of battery；
S3, when the full electricity of battery, instrument carry out sound, light, electric alarm remind driver's battery to have been filled with, driver's choosing
" 0 " shelves are selected, stopping signal is issued controller by driving switch, and controller continues to send halt instruction to energy regenerating clutch 9,
Clutch electronic control unit 5 controls hold-down mechanism 6 and stops working, and then makes secondary part 4 and 3 branch of active part, reaches at this time
The purpose isolated with generator 8 of engine 1；
S4, when the full electricity of battery, instrument carry out sound, light, electric alarm remind driver's battery to have been filled with, driver's choosing
" 0 " shelves are selected, stopping signal is issued controller by driving switch, and controller continues generator and sends halt instruction, generator outage.
To sum up, the present invention has the function for opening, closing energy recycle device by driver in not enough power supply, full electric situation
Can, driver's driving experience and enjoyment can be promoted under the premise of guaranteeing energy recovery function.The clutch that the present invention is arranged is being protected
Do not increase vehicle oil consumption additionally under the premise of card energy regenerating effect.In addition, the present invention has after full electricity in the non-hand of driver
The function of energy recycle device is automatically closed in system in the case where dynamic closing function, for preventing accumulator super-charge.
The above description is only a preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art
