The embodiment of the invention provides a kind of electrokinetic cell system fault detection method and devices.It is said separately below
It is bright.
A kind of electrokinetic cell system fault detection method is illustrated first.
As shown in Figure 1, the embodiment of the invention provides a kind of electrokinetic cell system fault detection method, the power battery
System is connected in series by multiple normal cell casees, and this method may include steps of:
First between the first voltage test point and vehicle body of total anode that the electrokinetic cell system is arranged in S101, acquisition
Voltage；And/or obtain between the second voltage test point and the vehicle body for total cathode that the electrokinetic cell system is set the
Two voltages；
Specifically, this method can be applied to be mounted in the electronic equipments such as the entire car controller on automobile, can also answer
For facilitating user to understand the working condition of electrokinetic cell system whenever and wherever possible in the mobile electronic devices such as mobile phone.
Specifically, as shown in Fig. 2, electrokinetic cell system can be gone here and there by n normal cell case (the abbreviation battery case in Fig. 2)
Join, can one first voltage of setting detects table between the total anode and vehicle body of electrokinetic cell system in advance, and/or

Total anode of nearly electrokinetic cell system or the other conductive components, such as vehicle body sheet metal, vehicle frame etc. of total cathode.In power battery system
When with vehicle body short trouble does not occur for the tie point between the normal cell case in system and normal cell case, two voltage detecting tables
The voltage detected is 0.
In practical applications, using the electronic equipment of this method can in real time or periodically with first voltage detect table or
Second voltage detects table communication, obtains the first voltage V1 that first voltage detection table measures；Second voltage detection table is obtained to measure
Second voltage V2.
S102, the first voltage absolute value be normal cell case voltage rating the first integral multiple the case where
Under, it is marked lighting from first voltage detection to first integer between total cathode of the electrokinetic cell system
Quasi- battery case and first integer add the tie point of 1 normal cell case to be determined as fault point；
For example, it is assumed that the voltage rating of normal cell case is 50V, when detected first voltage V1 is equal to -100V,
The absolute value of first voltage V1 is 2 times of the voltage rating of normal cell case, then illustrates the 2nd from total anode of standard electronic box
Short trouble has occurred in tie point and vehicle body between a standard electronic box and the 3rd normal cell case, i.e. the 2nd in Fig. 2 mark
Tie point between quasi- battery case and the 3rd normal cell case is fault point.
S103, the second voltage be normal cell case voltage rating the second integral multiple in the case where, will be from institute
Second voltage detection is stated to light to the second integer normal cell case between total anode of the electrokinetic cell system
The tie point of 1 normal cell case is added to be determined as fault point with second integer.
It is similarly assumed that the voltage rating of normal cell case is 50V, when detected second voltage V2 is equal to 50V, the
Two voltage V2 are 1 times of the voltage rating of normal cell case, then the 1st from total cathode of standard electronic box in explanatory diagram 2
Short trouble has occurred in tie point and vehicle body between standard electronic box and the 2nd normal cell case, i.e. (n-1)th mark in Fig. 2
The tie point of quasi- battery case and the n-th -2 normal cell casees is fault point.
In addition, preferably, after fault point is determining, the method that embodiment illustrated in fig. 1 provides can also include:

Except efficiency.
Due to only in total anode of electrokinetic cell system or total cathode setting voltage detecting point, according to what is detected
Voltage can only determine a fault point, can only be by distance if multiple tie points in electrokinetic cell system break down
A nearest fault point of test point detected, other fault points can only could be examined after the completion of fixed fault point is overhauled
It measures and.
It is therefore advantageous to, as shown in figure 3, on the basis of embodiment shown in Fig. 1, the embodiment of the invention also provides
Another electrokinetic cell system fault detection method is examined in total anode setting first voltage in the electrokinetic cell system
Measuring point, and in the case where second voltage test point is arranged in total cathode of the electrokinetic cell system, in step S102 and S103
Later, this method can also include:
S104, the absolute value for judging the first voltage and the second voltage absolute value and whether be the power
Voltage between the total anode and total cathode of battery system；
S105, if so, by according to the first voltage determine fault point with according to the second voltage determine therefore
Barrier point is determined as same fault point；Otherwise, by according to the first voltage determine fault point with it is true according to the second voltage
Fixed fault point is determined as different faults point.
For example, working as n=10, i.e., electrokinetic cell system is connected in series by 10 normal cell casees, normal cell case it is specified
When voltage is still 50V, the voltage between the total anode and total cathode of electrokinetic cell system is 500v；
If the first voltage V1=-100V measured, the second voltage V1=400V measured, | V1 |+| V2 |=500V, root
It is the connection between the 2nd normal cell case and the 3rd normal cell case in Fig. 2 according to the fault point that first voltage V1 is determined
Point is also between the 2nd normal cell case and the 3rd normal cell case in Fig. 2 according to the fault point that second voltage V2 is determined
Tie point.As it can be seen that working as the sum of the absolute value of first voltage V1 and the absolute value of second voltage V2 equal to electrokinetic cell system
When voltage between total anode and total cathode, the two fault points are same fault point；
If the first voltage V1=-50V measured, the second voltage V1=400V measured, | V1 |+| V2 |=450V, root
It is the connection between the 1st normal cell case and the 2nd normal cell case in Fig. 2 according to the fault point that first voltage V1 is determined
Point, and according to the fault point that second voltage V2 is determined between the 2nd normal cell case and the 3rd normal cell case in Fig. 2
Tie point.As it can be seen that when first voltage V1 absolute value and second voltage V2 absolute value and be not equal to electrokinetic cell system
Total anode and total cathode between voltage when, the two fault points are different faults point.

After being determined as different faults point, the method that embodiment shown in Fig. 3 provides can also include:
Fault type and position to user's output according to the determining fault point of the first voltage, and root is exported to user
Fault type and position according to the determining fault point of the second voltage.
Specifically, can be shown by the combination instrument, Multi-Function Display or audio-visual display screen etc. being mounted on automobile
Device intuitively exports display fault type and position of failure point to user, reduces troubleshooting steps, improves failure row
Except efficiency.
In practical applications, since the real work voltage of normal cell case can be by the practical charging of battery case, degree of discharge
Influence, therefore be difficult that normal cell case is made just to be maintained at voltage rating, it is possible to can be fluctuated relative to voltage rating,
This makes the first voltage obtained in step S101 and second voltage might not be exactly the whole of normal cell case voltage rating
Several times, but it is non-integral multiple.
It is therefore advantageous to, as shown in figure 4, the embodiment of the invention also provides another electrokinetic cell system fault detections

First between the first voltage test point and vehicle body of total anode that the electrokinetic cell system is arranged in S101, acquisition
Voltage；And/or obtain between the second voltage test point and the vehicle body for total cathode that the electrokinetic cell system is set the
Two voltages；
S106, the first voltage absolute value be normal cell case voltage rating the first non-integral multiple situation
Under, first non-integer is modified to third integer by default rule, will detect and be lighted to described from the first voltage
The third integer normal cell case and the third integer between total cathode of electrokinetic cell system add 1 standard
The tie point of battery case is determined as fault point；
When the scope range of the fluctuation of voltage of normal cell case fluctuates in lesser range, such as the wave between -5%~+5%
When dynamic, which can be the rule to round up, it can the rule of round off is to first voltage V1 and mark
The multiple of the voltage rating of quasi- battery case is modified, to carry out the positioning of fault point；
For example, working as n=10, the voltage rating of normal cell case is 100V, total anode and the total cathode of electrokinetic cell system
Between voltage when being 1000v, in the case where a kind of extreme: the real work electricity of each normal cell case in electrokinetic cell system
Pressure reduces 5% relative to voltage rating.Then when first voltage V1=-855=-8.55 × 100 measured, i.e. first voltage
V1 is -8.55 times of normal cell case voltage rating, and the 9th normal cell case and the can be determined after rounding up to 8.55
Short trouble has occurred between 10 normal cell casees.
When the scope range of the fluctuation of voltage of normal cell case fluctuates in the larger context, can determine according to the actual situation
