Abstract
The invention is specially used for solving the problem of electric leakage of the electric automobile, an acceleration sensor is used for sensing the driving condition of the electric automobile, once the electric automobile is impacted, the instantaneous acceleration change of the electric automobile is detected by the acceleration sensor, data is transmitted to a control system, a power supply line is cut off in time by the control system, the electric leakage is avoided, and the life safety of passengers is protected.
Description
Technical field
Patent of the present invention relates to a kind of electric automobile power-off protection method, and relating in particular to a kind of is automobile power-down guard method with acceleration transducer.
Background technology
Because urgent day by day energy crisis and the automobile irreplaceability in people's life; Each state is all at the power of the new forms of energy of seeking alternative oil as automobile; Electric automobile is as the most feasible present orthodox car replacer; Receive increasing concern, each big motor corporation releases the electric automobile sample and the production schedule one after another, wants position oneself at the forefront in this new automobile Great War.
The driving voltage of present Drive for EV battery pack is basically all about 380V; Voltage just can produce harm to human body more than 36V; Batteries of electric automobile group voltage is higher than this security value (s) far away, and the automobile critical piece all is that metal is processed, in case leak electricity; Gently then electric automobile itself is caused damage, seriously understand crisis rider's life security.
When particularly getting into an accident, because the distortion of car body or the distortion of supply line can increase the possibility of leaking electricity, harm rider's life security greatly.
Summary of the invention
Patent of the present invention is the electric leakage problem that is directed against electric automobile specially; Use the driving situation of acceleration transducer sensing electric automobile, in case clash into, acceleration change degree of the being accelerated transducer of instantaneous vehicle is found out; Data passes is in control system; In time cut off supply line by control system, avoid electric leakage to take place, protection rider's life security.
The object of the invention and solve its technical problem and adopt following technical scheme to realize: a kind of electric automobile power-off protection method; Form by batteries of electric automobile group (1), acceleration transducer (5), battery management system (BMS) (2), vehicle console (4), switch (6) (7); It is characterized in that: batteries of electric automobile group (1) electrically connects with battery management system (BMS) (2), automobile driving system (3), and acceleration transducer (5) electrically connects with battery management system (BMS) (2), vehicle console (4).
Aforesaid a kind of electric automobile power-off protection method, wherein said acceleration transducer (5) can connect battery management system (2) and vehicle console (4) simultaneously; Battery management system (2) also can be connected an acceleration transducer (5) respectively with vehicle console (4).
Aforesaid a kind of electric automobile power-off protection method, wherein said battery management system (2) is received the numerical value of acceleration transducer (5), judges whether to cut off battery output loop switch (6).
Aforesaid a kind of electric automobile power-off protection method, wherein said vehicle console (4) also can judge whether to cut off automobile batteries group (1) output loop switch (7) according to the numerical value of acceleration transducer (5).
Aforesaid a kind of electric automobile power-off protection method, wherein said battery management system (2) and vehicle console (4) can be controlled a circuit switching simultaneously, also can control a circuit switching (6) or (7) respectively.
