Electronlmobil usually adopts the power resources of a large amount of electrokinetic cells in groups as car load, and replace or mix and use traditional petrol and diesel oil, so being even more important of in the new forms of energy vehicle, showing of the high-voltage safety of car load.Traditional pure electric vehicle is because electrokinetic cell is more, electrokinetic cell has surpassed the safety voltage grade of 36V through the high-tension connector voltage class that is together in series, but the power high-tension current of pure electric vehicle only keeps shutoff device on the major loop of bus, the function of between each power battery pack, not cutting off automatically, this safety to the automotive servicing personnel is brought certain hidden danger; And, owing to do not have automatic disconnecting device, entire car controller can't handle the unforeseen circumstances that car load takes place when operation.
Summary of the invention
The purpose of this utility model is to provide a kind of electronlmobil high pressure automatic disconnecting device, and this automatic disconnecting device is to increase high-voltage relay in the inside of power battery pack, is subjected to the low pressure vehicle control unit controls; The low pressure entire car controller is gathered the signal of low pressure interlocking by the interlocking interface is installed on high-tension connector, and judges, cut off high relay whether, thus cut off the output of power battery pack high pressure.
To achieve these goals, the utility model adopts following technical scheme:
A kind of electronlmobil high pressure automatic disconnecting device, comprise several power battery pack, output high-voltage positive electrode and high voltage negative after several power battery pack are connected in series by high-tension connector, described high pressure automatic disconnecting device also comprises high-voltage relay and interlocking interface, the high-voltage relay main contact of high-voltage relay coil control linkage on the power battery pack mouth, high-voltage relay coil control line is connected to the low pressure entire car controller; The interlocking interface is installed on the high-tension connector, the folding of monitoring high-tension connector, and interlocking interface signal output line is connected to the low pressure entire car controller.
The high pressure output cathode end of described every group of power battery pack and negative pole end are equipped with a high-voltage relay main contact, the output of control high tension supply.
An interlocking interface is installed on described each high-tension connector.
The utility model is by increasing high-voltage relay in each power battery pack, and increases the interlocking interface function on the high-tension connector between each power battery pack, the high-tension apparatus.Gather, handle interlocking signal and other safety control signals by the low pressure entire car controller, the high-voltage relay coil is controlled, and then the high-voltage relay main contact carried out open and close, the connecting and disconnecting of the circuit of control power battery pack high-voltage output end, thus realize the function that high-voltage safety protects.
Description of drawings
Fig. 1 is a utility model electronlmobil high pressure automatic disconnecting device circuit diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, a kind of electronlmobil high pressure automatic disconnecting device, comprise several power battery pack E, high-tension connector LJ, high-voltage relay coil JD and interlocking interface JK, output high-voltage positive electrode and high voltage negative after several power battery pack E is connected in series by high-tension connector LJ, the high-voltage relay main contact K of high-voltage relay coil JD control linkage on power battery pack E mouth, high-voltage relay coil JD control line is connected to the low pressure entire car controller; Interlocking interface JK is installed on the high-tension connector LJ, the similar contact switch of interlocking interface JK, and the folding of monitoring high-tension connector LJ, interlocking interface JK output line is connected to the low pressure entire car controller.
The high pressure output cathode end of described every group of power battery pack E1 and negative pole end are equipped with high-voltage relay main contact K1, a K2, and each high-voltage relay main contact K1, K2 are subjected to separately that high-voltage relay coil JD1, JD2 control; And the high voltage negative end at every group of power battery pack E1 also is equipped with fuse Fo.Described each high-tension connector LJ goes up an interlocking interface JK is installed.
Principle of work of the present utility model is:
When high-tension connector LJ when high-tension apparatus or power battery pack En extract, when needing the cut off high power supply, be installed in interlocking interface JK on the high-tension connector LJ with high-tension connector LJ automatic cutout this moment, and the output low-voltage control signal is to the low pressure entire car controller.
After the low pressure entire car controller collected the on off mode of high-tension connector LJ interlocking signal, the processing of being correlated with was switched on or switched off high-voltage relay coil JD, and high-voltage relay coil JD control high-voltage relay main contact K cuts off or connect whole high tension loop.
When car load runs into emergency situation, the low pressure entire car controller to the control signal that the high-voltage relay coil JD in the high tension loop directly exports low pressure, cuts off or connects whole high tension loop according to car load control security strategy.
The collection point of the low pressure interlocking signal of the utility model electronlmobil high pressure automatic disconnecting device not only comprises the high-voltage connection of all power battery pack, also comprises all high-tension apparatuses.The connecting and disconnecting of low pressure vehicle control unit controls high tension supply.When the low pressure interlocking signal disconnected, the low pressure entire car controller sent instruction, cut off all high tension supplies, realized the thorough outage of power system, thereby realized the safety precaution of high-tension current.
It below only is preferred embodiment of the present utility model; be not to be used to limit protection domain of the present utility model; therefore, all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
