Description

A kind of anti-explosion electric car automatic burst-preventing control setup and control method
Technical field
The present invention relates to a kind of anti-explosion electric car automatic burst-preventing control setup and control method.
Background technology
When electronlmobil is continuously long-running,, must cause electrical motor and battery overheated if electrical motor on the electronlmobil and battery pack can not in time be discharged the heat that work time produces.When especially also having the attached current consuming apparatus of other automobiles such as air-conditioning at Che Nei, the load of battery pack will be bigger, and energy consumption is high; Not only make shorten the service life of electrical motor and battery; And buried potential safety hazard, functional reliability is lower, is prone to cause battery or electrical motor spontaneous combustion; Even cause blasting, serious threat is to chaufeur and passenger's life and property safety.
Summary of the invention
In order to overcome the above-mentioned defective that prior art exists, the present invention provides a kind of functional reliability higher anti-explosion electric car automatic burst-preventing control setup and control method.
Technical scheme of the present invention is:
The present invention's anti-explosion electric car automatic burst-preventing control setup comprises electronic control unit (ECU) and at least two battery pack; Electronic control unit is connected with each battery pack through different electronic switchs respectively; Each battery pack all links to each other with electrical motor; Each battery pack also links to each other with electronic control unit through the different temperature sensor respectively, and electrical motor also links to each other with electronic control unit through another temperature sensor, and electronic control unit is connected with attention display.
The control method of the present invention's anti-explosion electric car automatic burst-preventing control setup is: through the temperature of each battery pack of different temperature sensor online and electrical motor, during cruising, a certain battery pack is in running order; And other each battery pack is in off working state as emergency battery, at this moment; In running order battery pack temperature will constantly raise, and at this moment, the temperature signal that corresponding bonded assembly temperature sensor with this in running order battery pack will this in running order battery pack passes to electronic control unit (ECU); Electronic control unit carries out Treatment Analysis to temperature signal; When temperature reached predefined safe threshold value, ECU sent signal and breaks off corresponding electronic switch, and the battery pack that is in mode of operation is quit work; Simultaneously; Electronic control unit will make with corresponding another battery pack of this another electronic switch and get into mode of operation, and carry out monitoring temperature in real time through corresponding temperature sensor through another electronic switch of control; So, through the work that each temperature sensor, electronic switch and electronic control unit switch each battery pack back and forth, effectively prevent because of too high spontaneous combustion that causes of the temperature of a certain battery pack or blast; When motor temperature was too high, the temperature sensor that links to each other with electrical motor was passed to electronic control unit with the temperature signal of electrical motor, after the electronic control unit analyzing and processing signal was passed to attention display and reported to the police.
The present invention is switched through each battery pack alternately, thereby Vehicular battery can be taken turns to operate under suitable temperature, prevents that battery and electrical motor from working initiation battery and electrical motor generation spontaneous combustion or blast under excessive temperature.
Compact conformation of the present invention, functional reliability is higher, and heat dispersion is good, and energy consumption is low, and is applied widely.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
With reference to Fig. 1; Present embodiment comprises electronic control unit (ECU) 1, battery pack I 2 and battery pack II 3; Electronic control unit (ECU) 1 is connected with battery pack I 2 through electronic switch I 4, and electronic control unit 1 is connected with battery pack II 3 through electronic switch II 5, and battery pack I 2 all links to each other with electrical motor 6 with battery pack II 3; Battery pack I 2 links to each other with electronic control unit 1 through temperature sensor I 7; Battery pack II 3 links to each other with electronic control unit 1 through temperature sensor II 8, and electrical motor 6 links to each other with electronic control unit 1 through temperature sensor III 9, and electronic control unit 1 is connected with attention display 10.
In the vehicle operating process, temperature sensor I 7, temperature sensor II 8 and temperature sensor III 9 be the temperature of on-line real time monitoring battery pack I 2, battery pack II 3 and electrical motor 6 respectively, during cruising; Battery pack I 2 is in running order, and battery pack II 3 is in off working state as emergency battery; In long driving process; The temperature of battery pack I 2 will constantly raise, and at this moment, temperature sensor I 7 passes to electronic control unit (ECU) 1 with the temperature signal of battery pack I 2; ECU carries out Treatment Analysis to temperature signal; When temperature reached predefined safe threshold value, ECU sent signal and breaks off electronic switch I 4, and battery pack I 2 is quit work.Simultaneously, ECU will control electronic switch II 5, makes battery pack II 3 be in the work shape, and temperature sensor II 8 is monitored the temperature of battery pack II 3 in real time; The work of so switching two battery pack back and forth through each temperature sensor and ECU effectively prevents because of too high spontaneous combustion that causes of the temperature of a certain battery pack or blast; When electrical motor 6 temperature were too high, temperature sensor III 9 passed to the ECU that passes to of temperature signal attention display 10 with signal after the ECU analyzing and processing and reports to the police.
