In the first embodiment of the control method of the power battery preliminary filling resistance of vehicle of the present invention, the vehicle includes：
Power battery V, main positive relay K2, main negative relay K1, pre-charge-relay K3, preliminary filling resistance R, battery management system BMS
It is connect with the first end of the capacitance C by the positive relay K2 of the master with the anode of capacitance C, the battery, the battery
Cathode is born relay K1 by the master and is connect with the second end of the capacitance C, the pre-charge-relay K3 and the preliminary filling
Resistance R connections form preliminary filling circuit, and the preliminary filling circuit is in parallel with the positive relay K2 of the master, the battery management system BMS

Step S10 is closed the master and bears relay K1, is closed the pre-charge-relay K3, passes through the battery management
System BMS controls the preliminary filling circuit and charges to the capacitance C.
Specifically, the battery management system BMS controls the open and close of the pre-charge-relay K3, the battery
When management system BMS provides high level to the coil of the pre-charge-relay K3, the normally opened of the pre-charge-relay K3 touches
Head is closed, enable the pre-charge-relay K3；Conversely, when the battery management system BMS gives the pre-charge-relay K3
Coil provide low level when, forbidden energy pre-charge-relay K3.When user is inserted into key, when getting to " ON " shelves from " OFF " shelves, institute
It states main negative relay K1 to be closed, the battery management system BMS controls the pre-charge-relay K3 and is closed, the power battery
V bears relay K1, pre-charge-relay K3, preliminary filling resistance R, capacitance C with the master and forms closed circuit, the power battery V
It charges to the capacitance C.When the voltage at the both ends capacitance C reaches the 90%~95% of the power battery V both end voltages, preliminary filling
Electricity terminates.
Step S20 obtains continuous closure numbers of the vehicle pre-charge-relay K1 in preset time.
Specifically, the power battery V terminates to capacitance C chargings, and the pre-charge-relay K3 is disconnected, the master
Positive relay K2 is closed, and the high-voltage load of the vehicle is connected, and high pressure powers on.
In actual conditions, if short circuit or continue working occur for high-voltage load circuit, the voltage at the both ends capacitance C can not be
Precharge time, which obtains enough electric energy, makes the voltage at the both ends capacitance C increase to preset voltage, causes precharge time long,
The heat of preliminary filling resistance R is cumulative；Or in vehicle in use, the factors such as dielectric aging of capacitance C, affect capacitance C's
Parameter, then voltage drop ratio can also change；Or there is open fault in preliminary filling electrical circuit, the capacitance C cannot charge；Or by

Time can be configured according to actual conditions.
Step S30 judges whether the continuous closure number is more than default closure number.
Specifically, when the capacitance C is in precharge, the preliminary filling resistance R accumulates heat, under normal circumstances, the heat
Amount can all be radiated by other means such as cooling fin, will not be influenced too much to vehicle, however, when vehicle occurs as above-mentioned
When the reasons such as failure or maloperation, the precharge time of the capacitance C is long, and due to the multiple circulate operation of user, in advance
Overtime repeatedly generation is filled, then the heat that will result in the preliminary filling resistance R further adds up, the temperature of final preliminary filling resistance R
It may be more than specification limit, cause preliminary filling resistance R to damage, further can also damage battery or load.In order to avoid above-mentioned feelings
Condition occurs, and obtains the continuous closure number in preset time after the negative relay K1 of the vehicle master is closed, and further judge

It is not allowed more than in one minute 6 times.
Further, the default closure number can be determined according to the voltage of the power battery V.
Step S40 then keeps the pre-charge-relay K3 when the continuous closure number is more than default closure number
In off-state, forbid being pre-charged.
Specifically, when the continuous closure number is more than default closure number, the battery management system BMS controls institute
It is in off-state to state pre-charge-relay K3, forbids being pre-charged, cumulative in order to avoid the heat of the preliminary filling resistance R.
Step S50, when judging whether the pre-charge-relay K3 reaches default delay in the duration of off-state
Between；
Step S60 reaches the default delay time when the duration that the pre-charge-relay K3 is in off-state,
Respond the operation that the pre-charge-relay K3 is closed；
Step S70, when the pre-charge-relay K3 is not up to the default delay in the duration of off-state
Between, then it is in off-state to keep the pre-charge-relay K3, forbids being pre-charged.
Specifically, the pre-charge-relay K3 makes the preliminary filling resistance R in off-state and the default delay time that is delayed
It radiates in the default delay time, the temperature of the preliminary filling resistance R is finally made to control in a suitable range.When described
After preset time is preset in pre-charge-relay K3 delays, if user continues to open key, the vehicle responds the precharge
The operation that relay K3 is closed, the capacitance C preliminary fillings power on.Conversely, the holding in off-state in the pre-charge-relay K3
In the case that the continuous time is not up to the default delay time, then it is in off-state to keep the pre-charge-relay K3, is forbidden
Precharge.
In technical solution proposed by the present invention, relay K1 is born by being closed the master, is closed the pre-charge-relay
K3 obtains the continuous closure number in preset time after the negative relay K1 of the vehicle master is closed, and judges the Continuous Closed
Number is closed whether more than closure number is preset, when the continuous closure number is more than default closure number, then keeps described pre-
Charge relay K3 is in off-state in default delay time, forbids being pre-charged, when pre-charge-relay K3 delays are pre-
If after preset time, responding the operation that the pre-charge-relay K3 is closed.Technical solution control user proposed by the present invention exists
