Attached drawing in bright embodiment, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field
The every other embodiment that those of ordinary skill is obtained without making creative work, belongs to protection of the present invention
Range.
When an element was considered with another element " being connected ", it can be directly to another element or
It may be simultaneously present centering elements.Unless otherwise defined, all of technologies and scientific terms used here by the article and belong to this hair
The normally understood meaning of bright those skilled in the art is identical.Term used in the description of the invention herein
It is only for the purpose of describing specific embodiments and is not intended to limit the present invention.
Referring to Fig. 1, the functional block diagram of its electric vehicle 100 provided for present pre-ferred embodiments.The electronic vapour
Vehicle 100 includes for providing the battery pack 10 of electric energy, being connected with the battery pack 10 and for being managed to battery pack 10
Battery management system 20 and communication module 30 for the status information of battery pack 10 to be sent to monitor supervision platform 200.At this
In embodiment, the status information of the battery pack 10 includes the electric current of the battery pack 10, voltage, temperature and SOC (State
Of Charge, state-of-charge).
Specifically, the monitor supervision platform 200 is remote platform, also that is, backstage.It is appreciated that the monitor supervision platform 200 is same
When communicated with several electric vehicles 100, when electric vehicle 100 is in transport condition, the battery management system 20 will
The real time status information of the battery pack 10 is sent to the monitor supervision platform 200 by the communication module 30, so that related
Personnel can know the state of the battery pack 10 of every electric vehicle 100 in time, and when the battery pack 10 of certain electric vehicle 100
When occurring abnormal, scene can be gone to be safeguarded in time.In the present embodiment, the communication module 30 is GPRS (General
Packet Radio Service, general packet radio service technology) module.
Further, the battery management system 20 includes timer 21 and detection module 22.When the electric vehicle
10 it is not actuated when, that is, long-term when placing, the timer 21 is used to wake up the battery management system at interval of the predetermined time
20, also that is, the battery management system 20 is intermittent in running order.It is appreciated that not opened when electric vehicle 10 is in
When dynamic state, the battery management system 20 is in a dormant state.Specifically, the timer 21 is RTC (Real-Time
Clock, real-time clock) timer.The process of " wake-up " appeared in this paper is the transformation from dormant state to working condition.
After the battery management system 20 is waken up in running order, the detection module 22 starts to detect the electricity
The state of pond packet 10, and when the battery pack 10 is in abnormality, alarm signal is sent extremely by the communication module 30
The monitor supervision platform 200, and then related personnel is notified to be safeguarded in time to battery pack 10.In the present embodiment, the electricity
The abnormality of pond packet 10 includes that the SOC of battery pack 10 is less than default SOC, battery pack 10 is in leakage condition and battery pack 10
Temperature is higher than one or more of preset temperature.If battery pack 10 is in normal condition, battery management system 20 continue into
Enter dormant state, to reduce energy consumption.If being appreciated that, the SOC of battery pack 10 is less than default SOC, shows the electricity of battery pack 10
It measures too low, needs in time to charge to battery pack 10.If battery pack 10 is leaked electricity or the temperature of battery pack 10 is higher than default temperature
Degree, then show to be likely to occur short-circuit conditions inside battery pack 10, or even can cause nature.
In the present embodiment, the battery management system 20 passes through CAN (Controller Area Network, control
Device local area network) bus communicated with the communication module 30.It is appreciated that the communication module 30 and the monitor supervision platform
It is wireless telecommunications between 200.
The electric vehicle 100 of offer of the present invention, when the electric vehicle 100 is placed for a long time, the cell tube
Reason system 20 is capable of the state for detecting the battery pack 10 of discontinuity, and when the battery pack 10 is in abnormality, leads to
It crosses the communication module 30 and sends alarm signal to the monitor supervision platform 200, and then related personnel can be notified to safeguard, keep away
Exempt from due to electric vehicle 100 is placed for a long time because the security risk risen occurs.
Further, battery pack 10 further includes multiple battery modules 11, is in when the battery management system 20 is waken up
After working condition, the detection module 22 is additionally operable to detect the voltage of each battery module 11, and when a certain battery module 11
When the difference of voltage and the voltage of other battery modules 11 is more than preset difference value, start balance policy with to multiple battery modules 11
Equilibrium treatment is carried out, and then the consistency between multiple battery modules 11 can be improved, extends the service life of battery pack 10.
In one embodiment, the electric vehicle 100 further includes for starting the startup power supply 40 of electric vehicle 10, connecting
The switch module 50 being connected between the startup power supply 40 and the battery pack 10.When the battery management system 20 is waken up place
After working condition, the detection module 22 is additionally operable to detect the voltage of the startup power supply 40, and works as the startup power supply 40
Voltage when being less than first threshold, the closure of the switch module 50 is controlled, so that the battery pack 10 is that startups is electric
It charges in source 40.In the present embodiment, the switch module 50 is the faster DC relay of response speed.It can manage
Solution, when the voltage of startup power supply 10 is less than first threshold, the low battery of the startup power supply 10.
Further, after the battery pack 10 is that the startup power supply 40 charges, the detection module 22 is additionally operable to examine
The voltage of startup power supply 40 is surveyed, and when the voltage of the startup power supply 40 is more than second threshold, controls the switch module 50
It disconnects to stop continuing to charge for startup power supply 40, to prevent from overcharging the startup power supply 40, and then reaches to startup power supply
10 purposes further protected.It is appreciated that when the voltage of the startup power supply 40 reaches second threshold, the startup power supply
40 have expired electricity, therefore, it is necessary to stop continuing to charge to the startup power supply 40, to prevent because being overcharged to the startup power supply 40
And bring damage.After to 40 charging complete of startup power supply, the battery management system 20 can enter dormant state again.
In present embodiment, the startup power supply 40 is accumulator.
In addition, after the battery management system 20 is waken up in running order, if the detection module 22 detects
When the voltage of battery pack 10 is less than third threshold value, at this point, even if the voltage of startup power supply 40 is less than first threshold, the cell tube
Reason system 20 will not control switch module 50 and be closed to prevent contingency.
The present invention is not only in the description and the implementation described, therefore for the personnel of familiar field
Other advantage and modification is easily implemented, therefore in the essence without departing substantially from universal defined by claim and equivalency range
In the case of refreshing and range, the present invention is not limited to specific details, representative equipment and diagrams shown and described herein
Example.
