Embodiment, broadly falls into the scope of protection of the invention.
Refer to the flow chart that Fig. 1, Fig. 1 are high pressure preliminary filling control method provided by the present invention.
In a kind of detailed description of the invention provided by the present invention, high pressure preliminary filling control method mainly includes two steps, first
Step is: detects preliminary filling safety element before preliminary filling catalyst closes, and judges whether this preliminary filling safety element is in normal work
State, if it is, Guan Bi preliminary filling catalyst；Second step is: the precharging state parameter value of detection preliminary filling parts, and by it with pre-
If value compares, it is judged that whether preliminary filling completes preliminary filling parts, if it is, disconnect preliminary filling catalyst.
As in figure 2 it is shown, the flow chart that Fig. 2 is a kind of detailed description of the invention provided by the present invention.
Wherein, in the first step, the closed and disconnected of preliminary filling catalyst determines preliminary filling and the power-off of preliminary filling parts.In advance
Before filling catalyst Guan Bi, whether preliminary filling safety element is the most working properly, break down for detection preliminary filling safety element, i.e. detection.This
Place preferably, can be judged by detection current fuse or preliminary filling resistance, certainly, for improving response and safety as far as possible
Property, current fuse and preliminary filling resistance can detect simultaneously, when both duties are all normal, can close preliminary filling
Catalyst, starts to carry out preliminary filling for preliminary filling parts.Certainly, in the case of security performance requirement is the highest, it is also possible to single
Solely judge current fuse or the duty of preliminary filling resistance, only need one of them duty normally to get final product normally closed preliminary filling
Catalyst.It addition, preliminary filling safety element not only includes current fuse and preliminary filling resistance, remaining such as electric fuse, insurance resistance
Etc. using.
As it is shown on figure 3, Fig. 3 is the circuit detecting preliminary filling resistance states in a kind of detailed description of the invention provided by the present invention
Schematic diagram.
Concrete, when detecting preliminary filling resistance and whether being in normal condition, can be examined by circuit as shown in Figure 2
Survey.I.e. at two ends parallel connection low pressure accessory power supply, resistance, diode and the switch of preliminary filling resistance, resistor in parallel has for detecting
The voltmeter of its voltage, judges the duty of preliminary filling resistance by the magnitude of voltage at detection resistance two ends.Wherein, if resistance hinders
Value is R1, preliminary filling resistance is R, and the electromotive force of low pressure accessory power supply is E.Detection precharge before Guan Bi preliminary filling catalyst
Resistance, if the magnitude of voltage that voltmeter detects differ with u value be in ± 5% in, then show that the duty of preliminary filling resistance is normal；If
The magnitude of voltage that voltmeter detects and u value differ by more than ± 5% or magnitude of voltage be directly zero, then it represents that preliminary filling resistance burns,
Wherein:
U=E × R1/(R+R1)
As shown in Figure 4, the electricity of current fuse state is detected during Fig. 4 is a kind of detailed description of the invention provided by the present invention
Road schematic diagram.
Concrete, when detecting current fuse and whether being in normal condition, can be carried out by circuit as shown in Figure 4
Detection.I.e. at current fuse two ends parallel connection low pressure accessory power supply, resistance, diode and switch, resistor in parallel has for examining
Survey the voltmeter of its voltage, judged the duty of current fuse by the magnitude of voltage at detection resistance two ends.Pre-in Guan Bi
Current fuse is detected, if the magnitude of voltage that voltmeter detects differs place with the electromotive force value of low pressure accessory power supply before filling catalyst
In ± 5%, then show that the duty of current fuse is normal；If the magnitude of voltage that voltmeter detects be zero or close to
Zero, then show that current fuse blows.
Connecing above-mentioned, if judging when preliminary filling safety element is in normal operating conditions, then can close preliminary filling catalyst, start
Preliminary filling is carried out for preliminary filling parts.And before Guan Bi preliminary filling catalyst, it is contemplated that the structure essence of electric automobile voltage pre-charge circuit
Carefully, the time interval of power-on and power-off there is strict demand, to this end, the present embodiment also included in detection before Guan Bi preliminary filling catalyst
The step of lower electricity time interval.
Concrete, first detection preliminary filling parts start to this preliminary filling moment (to close preliminary filling from pre-charging time last time
The moment of catalyst) between time interval, be such as t, and judge the relation of this time interval and Preset Time, the most default
Time can be T.If t > T, then illustrate the interval of adjacent twice pre-charging time more than Preset Time, meet frequent power-on and power-off time
Between requirement；If t < T, then illustrate the interval of adjacent two pre-charging time less than Preset Time, be unsatisfactory for frequent power-on and power-off time
Between requirement, now need to postpone the closed procedure of preliminary filling catalyst, will extend interval time, until t > T.So, this reality
Execute example between Guan Bi preliminary filling catalyst, by setting up the step of detection preliminary filling interval time, it is to avoid high pressure preliminary filling road is frequent
The fault that power-on and power-off cause, improves service life and the reliability of preliminary filling parts.
Further, when whether judging the time interval of adjacent twice preliminary filling of preliminary filling parts more than Preset Time, can
By comprehensive descision interval time needed for the frequent power-on and power-off of car load power-on time and preliminary filling resistance.Concrete, first compare
Interval time needed for the frequent power-on and power-off of car load power-on time and preliminary filling resistance, and take the higher value in both, the most again should
Higher value compares with the time interval of the preliminary filling parts detected, if this higher value is less than time interval, then explanation is pre-
The time interval filling parts is more than Preset Time, i.e. meets time requirement；If this higher value is more than time interval, then explanation is pre-
The time interval filling parts is less than Preset Time, is unsatisfactory for time requirement, needs to postpone Guan Bi preliminary filling catalyst, when extending wait
Between.
It addition, when judging that preliminary filling safety element is in abnormal operating state, its fault can be occurred reason, time
Get off Deng reference record, and report Master Control Center, be simultaneously that occupant warns at human-computer interaction interface (HMI).
To sum up, when judging that preliminary filling safety element is in normal operating conditions, and the pre-charging time interval of preliminary filling parts
When also meeting Preset Time requirement, can close preliminary filling catalyst is that preliminary filling parts carry out preliminary filling.
As it is shown in figure 5, Fig. 5 is the electricity detecting preliminary filling catalyst state in a kind of detailed description of the invention provided by the present invention
Road schematic diagram.
And in order to improve the reliability of precharging circuit, the present embodiment, after Guan Bi preliminary filling catalyst, is also additionally arranged feedback
Link, i.e. detection preliminary filling catalyst is in closure state the most really.Concrete, can be detected by circuit as shown in Figure 5
The closure state of preliminary filling catalyst.I.e. at two ends parallel connection low pressure accessory power supply, resistance, diode and the switch of preliminary filling catalyst,
Resistor in parallel has the voltmeter for detecting its voltage, judges current fuse by the magnitude of voltage at detection resistance two ends
Duty (or contacts status).After preliminary filling catalyst Guan Bi or disconnection, preliminary filling contacts of contactor testing circuit starts, if
The magnitude of voltage that voltmeter detects is close or equal with the electromotive force of low pressure accessory power supply, then show that the contact of preliminary filling catalyst is closed
Close, be in closure state；If the magnitude of voltage that voltmeter detects is zero, then shows that the contact of preliminary filling catalyst disconnects, be in
Off-state.So, when detecting that preliminary filling catalyst is in closure state, follow-up priming procedure can be continued；When detecting
When preliminary filling catalyst is off, the most again performs Guan Bi preliminary filling catalyst action, continue detection preliminary filling catalyst afterwards
Whether it is in closure state, if being still within off-state, then illustrates that this preliminary filling catalyst has damaged, now complete fault
Record is also reported Master Control Center, warns for occupant in human-computer interaction interface simultaneously.
In the second step of the present invention, after preliminary filling parts start preliminary filling, need that it is carried out preliminary filling and complete to judge, it is to avoid mistake
Degree preliminary filling causes energy waste and heating to damage.Preliminary filling completes determination methods and is the precharging state parameter of detection preliminary filling parts
Value, then compares each precharging state parameter value with corresponding preset value, imposes a condition if met, then illustrates to charge in advance
Become, now can disconnect preliminary filling catalyst；If being unsatisfactory for imposing a condition, then explanation preliminary filling is not fully complete, and now postpones disconnecting preliminary filling
Catalyst, still needs to wait for.
Concrete, the precharging state parameter value of detection preliminary filling parts can be by the voltage of detection preliminary filling parts and electrokinetic cell
Voltage difference or detection preliminary filling parts pre-charging time (t1) complete.Certainly, for improving the reliability of testing result, voltage difference
Value and pre-charging time can detect simultaneously.If the voltage of the preliminary filling parts detected and the voltage difference of electrokinetic cell are less than pre-
If during pressure reduction (Us), then illustrating that most of electric energy of electrokinetic cell has been filled in preliminary filling parts, the pre-of preliminary filling parts charges
Become；If voltage difference is more than preset pressure, then explanation preliminary filling parts not yet preliminary filling is enough.If the pre-charging time detected (t1)
During less than Preset Time (T1), then the preliminary filling process of explanation preliminary filling parts completes in Preset Time, meets the requirements；If detecting
Pre-charging time more than Preset Time, then the preliminary filling process of preliminary filling parts is gone beyond the time limit by description, now it is believed that preliminary filling portion
Part breaks down, and stops preliminary filling process, is reported Master Control Center and warns.
It addition, combine above two judgment mode, also by the judgment mode increasing feedback element.Concrete, in advance
Filling parts and start preliminary filling and time preliminary filling completes, it can send, to Master Control Center, the preliminary filling feedback letter that preliminary filling starts to complete with preliminary filling
Number.Now, can the most really send these two kinds of preliminary filling feedback signals by detection preliminary filling parts and judge the preliminary filling of preliminary filling parts
Situation.
Preferably, the reliability judged for improving preliminary filling parts preliminary filling to complete, above-mentioned three kinds of judgment modes can be carried out simultaneously,
If i.e. in the pre-charging time of regulation, detect the preliminary filling feedback signal that the preliminary filling that preliminary filling parts are sent completes, and
The voltage difference detected is less than preset difference value, the most i.e. can determine whether that the preliminary filling of preliminary filling parts completes.
In sum, high pressure preliminary filling control method provided by the present invention, before preliminary filling starts, insured by detection preliminary filling
The duty of element, it is ensured that preliminary filling completes, prevents the dangerous situations such as short circuit, open circuit, rush of current；After preliminary filling starts, to preliminary filling
Parts detect in real time, after its preliminary filling completes, automatically disconnect preliminary filling catalyst, terminate preliminary filling.Therefore, the present invention is improving
On the basis of security performance, also improve the intelligence degree of preliminary filling process.
The present invention also provides for a kind of high pressure preliminary filling control system, including first detection module, the second detection module and break-make
