Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
The utility model in battery management system 3 by adding delayer, when battery management system 3 receives abnormal ring
When the interlocking signal of road, battery management system 3 sends abnormal loop interlocking report to entire car controller 1, and entire car controller 1 is based on different
Chang Huanlu interlocking reports feed back high pressure open command to battery management system 3, and battery management system 3 is in the high pressure for receiving feedback
Control high voltage connector 4 is just disconnected after the certain time length of open command, to leave the time that driver completes operation with high pressure for, is reduced
Danger coefficient.
Fig. 1 is the structural schematic diagram for the electric automobile high-voltage security loop interlock that the utility model embodiment provides,
For convenience of description, it only shows and the relevant part of the utility model embodiment.
The device includes：Entire car controller 1, each high voltage parts 2 and the battery management equipped with delayer of loop connection
System 3, i.e. entire car controller 1 are connect with each high voltage parts 2, and each high pressure part 2 is connect with battery management system 3, cell tube
Reason system 3 is connect with entire car controller 1, is to be connected in series between each high voltage parts 2；
Entire car controller 1 sends out the loop interlocking signal of low pressure after vehicle igniting, and the loop interlocking signal is through each series connection
After the high voltage parts 2 of connection, it is transmitted to battery management system 3, low voltage communication plug-in unit is equipped in battery management system 3, is used for
The loop interlocking signal is received and detects, when loop interlocking signal is normal, high voltage power battery 5 just there can be lasting power defeated
Go out, when each high voltage parts 2 are abnormal, i.e., the loop interlocking signal that battery management system 3 receives is abnormal loop interlocking signal
When, battery management system 3 is based on abnormal loop interlocking signal and sends abnormal loop interlocking report, vehicle control to entire car controller 1
Device base 1 processed feeds back high pressure open command in abnormal loop interlocking report to battery management system 3, and TV manages system 3 and is based on height
