Description
Technical field
This utility model is related to the control system of electric automobile, specifically a kind of electronic vapour for pure electric automobile control
Car emergency power off system.
Background technology
When pure electric automobile significant trouble occurs in the process of moving, driver is directly direct by way of electricity under key
Power-off, but in such cases, one side motor does not also stop, and there is impulsive force, on the other hand electricity after being likely to result in power-off
Pond is not also carried out broken height pressure and is prepared, and instant cut-off is likely to result in the disconnection of battery main relay too fast.This kind of power-off form, without control
Logic processed, it is understood that there may be potential safety hazard.
The content of the invention
Technical problem to be solved in the utility model, there is provided one kind can be to improving electric automobile emergency power off to control
The adverse effect that system is brought, improves the electric automobile emergency power off system of security of system and equipment operational reliability.
Electric automobile emergency power off system of the present utility model includes the battery module for belonging to electric vehicle master drive system
And motor module, the battery module and motor module are connected in the current supply circuit between accumulator the two poles of the earth；Also set in system
An entire car controller is equipped with, the entire car controller connects battery module and motor module respectively, and control can be issued and referred to
Make and receive the battery main relay status signal and motor speed signal of feedback；The control signal of the entire car controller connects
Cut-off switch is connect, emergency power off control signal can be input into entire car controller；The control output end of the entire car controller connects
A relay R is met, and is capable of the adhesive and release of control relay R；The contact of the relay R is connected to the battery mould
In the current supply circuit of block and motor module, can close or cutoff circuit.
The entire car controller connects battery module and motor module by CAN.
The power end connection accumulator of the entire car controller simultaneously provides power supply by accumulator.
This utility model, can be before electric automobile whole power-off to main drive by the logic control to emergency power off process
The battery module of dynamic system and motor module state carry out corresponding operating, reliable so as to ensure that security of system and equipment
Property.
Description of the drawings
Fig. 1 is systematic schematic diagram of the present utility model.
Specific embodiment
As illustrated, the electric automobile emergency power off system include belonging to the battery module of electric vehicle master drive system and
Motor module, the battery module and motor module are connected in the current supply circuit between accumulator the two poles of the earth；Also set up in system
There is an entire car controller, the entire car controller connects battery module and motor module respectively, and can issue control instruction
And receive the battery main relay status signal and motor speed signal of feedback；The control signal connection of the entire car controller
Cut-off switch K, can be input into emergency power off control signal to entire car controller；The control output end connection of the entire car controller
One relay R, and it is capable of the adhesive and release of control relay R；The contact J of the relay R is connected to the battery mould
In the current supply circuit of block and motor module, can close or cutoff circuit.Entire car controller connects battery module by CAN
And motor module.The power end connection accumulator of entire car controller simultaneously provides power supply by accumulator.
Its course of work is：
When pure electric automobile normally travel, the control output end of entire car controller persistently exports work to control relay R
Make voltage, make relay R adhesives, the current supply circuit of its contact turn-on battery module and motor module makes battery module and motor
Module normal work；
When there is significant trouble during traveling, cut-off switch is pressed, entire car controller detects low control signal, passes through
CAN sends main relay close commands to battery module, after battery module receives the order, actively cuts off main relay
Device, and the state of main relay is fed back to entire car controller；
It is when entire car controller is 0 signal by CAN reception battery main relay off-state and motor speed, whole
Vehicle controller stops output services voltage, and relay R disconnects, and makes accumulator power to battery module and motor module；
It is after vehicle shutdown, entire car controller is electrically disconnected by key.
