Detailed description of the invention
Below by embodiment, and combine accompanying drawing 1-5, technical scheme is described in further detail.
The invention provides a kind of installation for electric automobile quick change battery to put in place and the real-time monitoring of high pressure connection status
Method, the method is by being arranged on the position sensor 7 in fast-changed support 1 battery mount point 6 and the temperature of quick change connector
Sensor 8, respectively monitoring quick change battery 4 installation site and the temperature of its connection terminal of quick change connector, it is achieved to quick change battery 4
The real-time monitoring of installation site.
Fig. 1 is quick change battery 4 and fast-changed support 1 schematic diagram, as it is shown in figure 1, quick change battery 4 is arranged on by suspension centre 5 soon
Changing on support 1, the battery mount point 6 of fast-changed support 1 is mounted with that position sensor 7, the present embodiment position sensor 7 use Hall
Sensor, quick change battery 4 is installed on fast-changed support 1 by suspension centre 5, and magnetic material on suspension centre 5, when quick change battery 4 is installed
After putting in place, if battery suspension centre 5 and battery mount point 6 are apart from less than or equal to setpoint distance, position sensor 7 output low level,
Controller judges that battery is installed and puts in place, it is allowed to high pressure on vehicle.If mount point is more than setpoint distance, Hall element output height
Level, controller judges that battery is installed and does not puts in place, reports battery to install fault not in place；After battery is installed and put in place, there is also
High pressure quick change connector contacts insecure situation, by the temperature sensor 8, Ke Yishi being arranged on high-low pressure contact terminal
The now diagnosis to mount point, when high pressure connects unreliable, HV Terminal can generate heat, and by gathering the temperature of terminal, can determine whether
HV Terminal connects fault.
Fig. 2 is quick change battery 4 quick change connector temperature acquisition schematic diagram.Quick change connector is by being arranged on fast-changed support 1
Socket 2 and the plug 3 being arranged on quick change battery 4 form, quick change connector terminals is by low-voltage signal terminal 9 and HV Terminal
Composition, high pressure anode 10 and high pressure negative terminal 11 are respectively mounted temperature sensor 8, when voltage end component connects unreliable, high pressure
When terminal leads to super-high-current, terminal can generate heat, and whether exceedes certain threshold value by the temperature judging HV Terminal, it is achieved to high pressure
The judgement of connection reliability.
Fig. 3 is battery installation site principle of induction, and battery is installed suspension centre 5 and is made up of magnetic material, when suspension centre 5 is pacified with battery
Decorate 6 distances reach sense setpoint distance time, Hall element output low level, controller judge battery installation put in place.Work as electricity
Pond is not properly installed, and Hall element does not sense the magnetic of suspension centre 6, Hall element output high level, controller
Send battery and information not in place is installed.
Fig. 4 is the curve of position sensor 7 output signal and distance of reaction.When battery suspension centre 5 is pacified with fast-changed support 1 battery
Decorate 6 distances less than sensing setpoint distance Xmm, Hall element output low level；When battery mount point 6 sets apart from more than sensing
Set a distance Xmm, Hall element output high level.
Fig. 5 is quick change battery 4 installation site diagnostic flow chart.Controller the present embodiment uses battery management system, works as electricity
After pond management system completes to initialize, read Hall element output signal Vout, if Vout is low level, then judge battery
Installation puts in place, if Vout is high level, then battery is not mounted to position, and controller report battery is not mounted to position, does not allow row
Car.After judging that battery installation puts in place, controller reads temperature sensor 8 signal, when temperature exceedes the threshold value of setting, then judges
It is unreliable that high pressure connects termination contact, takes to drop power policy.
The present embodiment is the embodiment of example of the present invention, for those skilled in the art, in the present invention
On the basis of disclosing application process and principle, it is easy to make various types of improvement or deformation, be not limited solely to the present invention
Structure described by above-mentioned detailed description of the invention, the most previously described mode is preferred version, and the most restrictive
Meaning, every according to the present invention made equivalence change with amendment, all in the scope protection domain of claims of the present invention.
