Abstract
The invention discloses a method using a vehicle controller for battery management of an electric vehicle, the vehicle controller performs, from the point of vehicle control, all-sided comprehensive operation processing according to the vehicle state, and according to the to-be-realized function demands of a vehicle on a running battery pack, performs corresponding function strategy and algorithm processing on the battery pack; the vehicle controller sends operation results to a battery management system, the battery management system executes commands of the vehicle controller and feeds back the executed results to the vehicle controller; the vehicle controller analyzes the fed-back results to determine whether to continue a battery management procedure, and if necessary, the vehicle controller continues issuing execution commands to a battery management system load; and after the battery management system and the load both complete the execution commands, the procedure is over, and the vehicle controller quits the procedure. According to the method, control functions of the battery pack are integrated in the vehicle controller, the vehicle controller controls from the point of vehicle, so that the vehicle running is more smoothly and comfortable.
Description
Technical field
The present invention relates to battery management, particularly a kind of method of carrying out batteries of electric automobile management with entire car controller.
Background technology
Battery management system is being born the functions such as the strategy of the various functions of battery pack and the analysis of algorithm, strategy execution, signal sampling measurement, battery status estimation, sampling and fault message and processing.Battery pack information sampled measurements part, as monomer voltage detection, battery temperature detection, total voltage detection, current detecting, insulation resistance value detect; Battery status estimation part, as remaining capacity SOC, cell health state SOH, charge capacity, discharge electricity amount, battery cell maximum differential pressure, battery pack maximum temperature difference etc.; Policing algorithm and operating part, as High voltage output control, battery balanced function, management of charging and discharging, heat management, troubleshooting, the current available power calculation etc. that discharges and recharges.
The battery pack of electric automobile is all to be controlled by battery management system at present, between entire car controller and battery management system, just carry out exchanges data, entire car controller can not carry out battery control, may can not fully understand car load demand by battery management system like this, battery system can not well be made corresponding actions.And car load demand often changes, cause certain difficulty to the exploitation of battery management system, and the entire car controller of different car load factory can coordinate with it with different battery management systems, cause battery management system consistency poor, be unfavorable for industrialization.For the demand of car load, depot needs and battery management system manufacturer is linked up frequently, and this demand of car load is that exploitation along with car load constantly occurs, to the exploitation of battery management system, brings larger difficulty.Different vehicles is in different periods, and their demand is all different, and corresponding battery management system is just different, has caused the version of battery management system to increase.
Summary of the invention
For overcoming the defect of above-mentioned prior art, the invention provides a kind of method of carrying out batteries of electric automobile management with entire car controller.
The technical solution used in the present invention is:
A method of carrying out batteries of electric automobile management with entire car controller, step comprises:
(1) entire car controller, from the control angle of car load, carries out comprehensive calculation process according to the operating mode demand of car load, and the demand of the function that will realize operation battery pack according to car load, carries out the processing of battery pack corresponding function strategy and algorithm;
(2) then entire car controller issues battery management system operation result, and battery management system is carried out the order of entire car controller, and a result feedback of carrying out is to entire car controller;
(3) result of entire car controller analysis feedback, judging whether needs to continue to carry out battery management program, if needed, continues the load to battery management system and assigns fill order, does not need, and exits battery management program;
(4) battery management system and load all complete after fill order, EP (end of program), and entire car controller quits a program.
Beneficial effect of the present invention has:
(1) the present invention is integrated in the control function of battery pack in entire car controller, has increased the integrated level of controller; Entire car controller is controlled from the angle of car load, and the control strategy of selecting like this can make vehicle operating more steady, comfortable;
(2) the present invention has simplified battery management system function, and making it is execution unit, and the scheme of battery management system is just easily fixed up like this, and its industrialization just more easily realizes;
(3) policy section of battery management system of the present invention is completed by entire car controller, can save the hardware components of battery management system, has reduced cost; The change of car load strategy, relates to battery control section, directly in entire car controller, changes, and does not need to link up with battery management system developer, has shortened the construction cycle.
Accompanying drawing explanation
Fig. 1 is the method flow diagram that carries out batteries of electric automobile management with entire car controller of the present invention.
Embodiment
For convenience of those skilled in the art, understand technology contents of the present invention, below in conjunction with embodiment, the present invention is described in further detail.
As shown in Figure 1, the disclosed method of carrying out batteries of electric automobile management with entire car controller, comprises step:
(1) under vehicle control unit controls pattern, entire car controller is from the control angle of car load, according to the operating mode demand of car load, carry out comprehensive comprehensive calculation process, and the demand of the function that will realize operation battery pack according to car load, carry out the processing of battery pack corresponding function strategy and algorithm;
(2) then entire car controller issues battery management system and load operation result, and the order of entire car controller is carried out in battery management system and load, and the result feedback that battery management system handle is carried out is to entire car controller;
(3) entire car controller is analyzed the result of battery management system feedback, and judging whether needs to continue to carry out battery management program, if needed, continues the load to battery management system and assigns fill order, does not need, and quits a program;
(4) battery management system and load all complete after fill order, EP (end of program), and entire car controller quits a program.
Above-described embodiment is only wherein specific implementation of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these apparent replacement forms all belong to protection scope of the present invention.
