Abstract
The utility model relates to a wire harness detection device used for multi-cell batteries. The wire harness detection device includes a detection system; the detection system comprises a plurality of series combination units of resistors and light emitting diodes; the series combination units are in series connection with one another; the number of the series combination units is the same with the number of cells of a multi-cell battery pack which are connected in series with one another; and two ends of each series combination unit is correspondingly connected with two ends of each cell through a wire harness. With the wire harness detection device used for multi-cell batteries of the utility model adopted, whether the connection of the wire harness is right or not can be effectively and correctly judged, and therefore, it can be ensured that a battery management system will not be damaged because of the wrong connection of the wire harness.
Description
Technical field
The utility model relates to a kind of Beam Detector for multi cell battery.
Background technology
in the industries such as new-energy automobile, the power brick of multicore series connection is an indispensable assembly, has the positive and negative terminal that multiple interfaces connect respectively each battery core, in order to detect battery core state in battery management system.Due to the connected mode of each battery core in series connection, therefore between each interface, all there is voltage difference.Connect correct in the situation that at wire harness, battery management system can correctly detect each battery core state, and system can normally be worked.But when being connected with, wire harness mistakes, can cause the voltage difference mistake of corresponding interface, even electric potential difference is contrary, especially in the more new-energy automobile battery of battery core number, the electric potential difference of this mistake can directly cause the damage of controller, and serious situation may cause burns wire harness or even power brick of circuit board.
Utility model content
The purpose of this utility model is to provide a kind of Beam Detector for multi cell battery, can detect the wire harness between power brick and battery management system, effectively prevent the situation that causes controller damage or circuit board to burn due to the mistake that wire harness connects, to overcome prior art above shortcomings.
The purpose of this utility model is achieved through the following technical solutions:
A kind of Beam Detector for multi cell battery, comprise detection system, described detection system comprises the tandem compound unit of some resistance and light emitting diode, between described tandem compound unit, for being connected in series, the quantity of described tandem compound unit is identical with the quantity of the battery core of the mutual series connection of multi cell battery bag; The two ends of each described tandem compound unit are connected respectively the two ends in each battery core by wire harness.
Further, each described tandem compound unit is provided with LED light.
The beneficial effects of the utility model are: whether the connection that the Beam Detector for multi cell battery of the present utility model can correctly and effectively determine wire harness is correct, thereby guarantee that battery management system etc. can not cause damage because of wire harness connection error.
Brief description of the drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the Beam Detector annexation block diagram for multi cell battery described in the utility model embodiment;
Fig. 2 is the circuit theory diagrams of the Beam Detector for multi cell battery described in the utility model embodiment.
In figure:
1, multi cell battery bag; 2, wire harness; 3, detection system; 4, battery core.
Embodiment
As shown in Figure 1, the Beam Detector for multi cell battery described in the utility model embodiment, comprise detection system 3, described detection system 3 comprises the tandem compound unit of some resistance and light emitting diode, between described tandem compound unit, for being connected in series, the quantity of described tandem compound unit is identical with the quantity of the battery core 4 of the mutual series connection of multi cell battery bag 1; The two ends of each described tandem compound unit are connected respectively the two ends in each battery core 4 by wire harness 2; Each described tandem compound unit is provided with LED light.
As shown in Figure 2, the principle of work of the Beam Detector for multi cell battery described in the utility model embodiment, wherein, E1 in figure, E2 ... En represents battery core, R1, R2 ... Rn represents resistance, D1, D2 ... Dn represents light emitting diode.
When wire harness connects when correct, all there is a forward voltage at the two ends of each resistance and light emitting diode combined, and therefore light emitting diode flows through a forward current, LED lighting.In the time of the wrong connection of wire harness, there is a reverse voltage at the diode two ends corresponding with wrong wiring harness interface, and diode cut-off is not luminous.Therefore can judge by the light on and off state of light emitting diode whether wire harness connects correct.The wire harness of exact connect ion is used in work system, can ensures that battery management system avoids the damage causing because of wire harness wrong.
When use, this device is consistent with the interface of battery management system, directly wire harness end is docked with this device.For example, primary element management system connector the first pin connects power brick first segment battery core positive pole, now this is installed to the first pin and connects power brick first segment battery core positive pole, by that analogy.All LED lamps as upper in this device are all lighted, represent that strand design is errorless, if there is LED lamp not light, corresponding strand design being described or connecting has problem, this wire harness just can not be directly connected on battery management system, otherwise can cause damage to battery management system.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
