Abstract

The invention provides a high-voltage power battery contactor detection method and device and a battery management system. A detection mode special for detecting contactors is provided for the battery management system besides the normal work mode. When the battery management system is in a standby condition, the battery management system receives a control command sent by an external control device and gets into the contactor detection mode, closing or opening operation of the contactors is assigned according to the command of the external control device or closing or opening operation of the contactors is conducted in sequence according to a pre-stored detection sequence, and the battery management system automatically detects whether the functions of the contactors are normal or not and feeds back results to the external control device. By the adoption of the above scheme, whether the fault that all contactors cannot be closed or opened due to adhesion and aging occurs or not can be rapidly and accurately judged. Due to the adoption of the automatic technology, potential safety hazards do not exist.

Description

High voltage power battery contactor detection method, equipment, battery management system and automobile

Specific embodiment
Embodiment 1
The present embodiment provides a kind of high voltage power battery contactor detection method, and the method is applied to cell tube Reason system, as shown in Fig. 2 comprising the steps:
S1:Judge whether the command information for receiving starting contactor detection pattern, if then entering step S2, if otherwise repeating this step.
S2:Whether the current operating state for judging the battery management system is upper electric waiting state, if Then enter step S3.In this step, upper electric waiting state refers to that battery management system receives Key On After signal activation, battery management system self-inspection is completed, and waits the state of entire car controller order.
S3:According to the command information starting contactor detection pattern.
S4:Judge to detect whether the closure/opening operation for specifying catalyst is successful, step is entered if success S5.Step S6 is entered if unsuccessful.Concrete detection process is as follows:
S41:The feedback signal of collection measurement terminal voltage signal or specified catalyst.
S42:Judge that the terminal voltage signal or the feedback signal of specified catalyst of measuring is with command information It is no consistent;Closure/opening operation the success for specifying catalyst is judged if consistent, otherwise judges to specify contact The closure of device/opening operation failure.
Due to being the detection pattern entered on the premise of battery management system is waited for, shape is being waited During state, all of catalyst is all off-state.So if when detecting to a certain catalyst, should This is the detection for first carrying out catalyst closed procedure and then the operation for carrying out catalyst disconnection again.
S5:Send the testing result signal for representing the specified catalyst closure/opening operation by test.
S6:Send and represent the specified catalyst closure/opening operation not by the testing result signal of test.
The such scheme that the present embodiment is provided, due to adopting Automatic Measurement Technique completely, therefore, it is possible to it is quick, Judge exactly each catalyst whether due to adhesion, the aging failure for causing to close or disconnect simultaneously And, there is no potential safety hazard in reliability height.
The such scheme of the present embodiment, battery management system can automatically be carried out after into detection pattern Catalyst is detected, or targetedly connect to a certain according to command information under the control of command information Tentaculum is detected.
As a kind of attainable scheme, can arrange in command information special command symbol be used to refer to be Catalyst detection is carried out automatically by battery management system to need for being connect again after wait external command information Tentaculum detects that battery management system is judged according to command information is received.As shown in figure 3, step S3 is specifically included:
S301:Judge whether the command information is automatic detection command information, if then entering step S302, otherwise into step S303.
S302:The control signal of closure/disconnection specified catalyst is sent according to predefined procedure.
S303:Receive the command information that catalyst is specified in closure/disconnection.
S304:Send the control signal of closure/disconnection specified catalyst.
As another kind of attainable scheme, can be with prespecified first Preset Time, if pre- first If battery management system is all not received by detecting the command information of a certain catalyst in the time, then judge into (this judgment mode needs the equipment for ensureing to send command information to be constantly in normally to enter autosensing mode Work and can realize data transfer with battery management system) as shown in figure 4, step S3 is specifically included:
S311:Judge whether to receive the instruction letter that catalyst is specified in closure/disconnection in the first Preset Time Breath, if then entering step S312, otherwise into step S313.
S312:Send the control signal of closure/disconnection specified catalyst.
S313:The control signal of closure/disconnection specified catalyst is sent according to predefined procedure.
In such scheme, battery management system is entered after detection pattern, can be automatic by battery management system Carry out specifying the contact/opening operation of catalyst to be tested according to predefined procedure.If it should be noted that In detection process, it is found that a certain catalyst breaks down, such as adhesion fault, then should feed back fault diagnosis knot Really, and stop to carry out the detection of other catalysts.Reason is as follows:If cathode contact device sticks together, this When still carry out the diagnosis of positive contact device according to predefined procedure, circuit turn-on, the actual shape of battery can be caused State is while there is two catalyst closures.Battery management system is entered after detection pattern, it is also possible to by outside Control device is sent after the instruction that the contact/opening operation to specifying catalyst is tested, by battery management System is tested according to contact/opening operation that instruction carries out catalyst.Former scheme can more be accelerated Speed efficiently carries out the detection of catalyst closure/opening operation, and latter scheme can be according to user's request pair The catalyst specified is detected.Which kind of can be selected concrete application according to practical situation.
Used as a specific embodiment, the catalyst includes positive contact device, cathode contact device and pre- Fill catalyst.In some cases, it is also possible to there is charging contactor, its detection mode is also identical, Do not repeating herein.It should be noted that no matter which kind of mode is adopted, for the detection ordering of catalyst May not necessarily limit, both can according to positive contact device, cathode contact device, preliminary filling catalyst order, Can also according to cathode contact device, preliminary filling catalyst, positive contact device order, can also be that other are suitable Sequence.Which kind of no matter takes sequentially detected, detection specify the closure/opening operation of catalyst whether into In the step of work(, synchronization only allows a catalyst to close, and for a certain specified catalyst, First detect whether success detects again whether its opening operation is successful, and a certain specified catalyst breaks to its closed procedure After opening other catalysts are detected again.Gradually close first and then disconnect in a certain order catalyst, So to ensureing that system can return to the i.e. all catalysts of original state and all break after the completion of a catalyst detection The state opened, therefore electric high-voltage risk for security is not result in, further ensure testing result Safety.
