Abstract
The invention provides an automatic high-voltage cutoff system for a battery pack of a pure electric vehicle. The automatic high-voltage cutoff system comprises a vehicle body collision sensor, a safety airbag controller, a battery system controller and a high-voltage main relay in the battery pack, wherein the vehicle body collision sensor is connected with the safety airbag controller, the safety airbag controller is connected with the battery system controller, and the battery system controller is connected with the high-voltage main relay in the battery pack. According to the automatic high-voltage cutoff system, a high-voltage power supply can be automatically cut off during vehicle collision, so that the injury to personnel caused by the high voltage leakage of the pure electric vehicle is avoided.
Description
Technical field
The present invention relates to pure electric automobile field, relate in particular to pure electric automobile power brick high pressure from cutting system.
Background technology
Existing pure electric automobile cut off battery system high-tension current output before vehicle collision, and vehicle may be damaged and contact with vehicle body and cause high pressure to leak electricity at collision process mesohigh current consumer and high-tension line, endangers chaufeur and other passenger life safety.
Summary of the invention
The technical problem to be solved in the present invention, is to provide pure electric automobile power brick high pressure from cutting system, can cause the problem of high pressure electric leakage while solving vehicle collision.
The present invention is achieved in that
Pure electric automobile power brick high pressure is from cutting system, comprise vehicle body crash sensor, safety air sac controller, battery system controller and power brick inner high voltage main relay, described vehicle body crash sensor is connected with safety air sac controller, described safety air sac controller is connected with battery system controller, and described battery system controller is connected with power brick inner high voltage main relay.
Further, the CAN that is connected to of described safety air sac controller and battery system controller is connected.
And the present invention also provides a kind of pure electric automobile, described pure electric automobile includes pure electric automobile power brick high pressure from cutting system, described pure electric automobile power brick high pressure comprises vehicle body crash sensor, safety air sac controller, battery system controller and power brick inner high voltage main relay from cutting system, described vehicle body crash sensor is connected with safety air sac controller, described safety air sac controller is connected with battery system controller, and described battery system controller is connected with power brick inner high voltage main relay.
Further, the CAN that is connected to of described safety air sac controller and battery system controller is connected.
Tool of the present invention has the following advantages: by safety air sac controller, judge whether vehicle is about to or is bumping, and by battery system controller accurately and timely cut off high power brick high-tension current export, thereby avoid, because of high pressure electric leakage, chaufeur and other occupants are caused to secondary harm.
Accompanying drawing explanation
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is system architecture schematic diagram of the present invention.
The specific embodiment
Refer to shown in Fig. 1, below the present invention is described in detail.
Pure electric automobile power brick high pressure is from cutting system, comprise vehicle body crash sensor 1, safety air sac controller 2, battery system controller 3 and power brick inner high voltage main relay 4, vehicle body crash sensor 1 is connected with safety air sac controller 2, safety air sac controller 2 is connected with battery system controller 3, and battery system controller 3 is connected with power brick inner high voltage main relay 4.
Native system is when collision happens, vehicle body crash sensor 1 can detect the acceleration due to gravity whether crash acceleration is 2 times, safety air sac controller 2 can, when receiving the collision alarm that vehicle body crash sensor 1 transmits, be judged whether to eject safety air bag and be sent collision alarm by calculatings.Collision alarm can be by sending to battery system controller 3 with being connected of battery system controller 3, and conventional safety air sac controller 2 is connected with the CAN that is connected to of battery system controller 3.Battery system controller 3 is received after collision alarm, controlling high-tension battery bag inner high voltage main relay 4 disconnects, thereby cut off high output, battery system controller, for when receiving the collision alarm of safety air sac controller, is controlled power brick inner high voltage main relay cut off high power supply.
And the present invention also by this pure electric automobile power brick high pressure from cutting off system employs on pure electric automobile, a kind of pure electric automobile is provided, this electronlmobil includes above-mentioned pure electric automobile power brick high pressure from cutting system.
To sum up, the present invention can be when vehicle collision or before battery system High voltage output is cut off, play the high pressure electric leakage that the vehicle deformation avoiding causing because of vehicle collision causes dangerous, thereby avoid, because of high pressure electric leakage, chaufeur and other occupants are caused to secondary harm.
Although more than described the specific embodiment of the present invention; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present invention; those of ordinary skill in the art are in equivalent modification and the variation done according to spirit of the present invention, all should be encompassed in the scope that claim of the present invention protects.
