Detailed description of the invention
Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings, and the most same or similar label represents same or similar element or has the element of same or like function.The embodiment described below with reference to accompanying drawing is exemplary, it is intended to be used for explaining this utility model, and it is not intended that to restriction of the present utility model.
Control system and the electric automobile of electric automobile of the present utility model are described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the control system according to electric automobile of the present utility model.
As it is shown in figure 1, the control system of electric automobile of the present utility model, including: control switch 10, electrokinetic cell 20, low tension battery 30, voltage reduction module 40 and controller 50.
In this utility model, the high-pressure side of voltage reduction module 40 is connected with electrokinetic cell 20 by controlling switch 10, the low-pressure side of voltage reduction module 40 is connected with low tension battery 30, when controlling switch 10 Guan Bi and voltage reduction module 40 starts, voltage reduction module 40 can charge for low tension battery 30 to after the high-tension electricity blood pressure lowering of electrokinetic cell 20.In this utility model, controller 50 is connected with control switch 10 and voltage reduction module 40 respectively, and the open-circuit voltage of low tension battery 30 monitored under vehicle by controller 50 after electricity, and controls to switch break-make and the start and stop of voltage reduction module 40 of 10 according to open-circuit voltage.
For realizing above-mentioned control switch 10 and the correlation function of voltage reduction module 40, in a specific embodiment of the present utility model, controlling switch 10 can be normally opened relay, and voltage reduction module 40 can be DC/DC transducer, and controller 50 can be battery management system.
In this utility model, for reducing the consumption of electric energy, controller 50 only can activate to monitor the open-circuit voltage of low tension battery 30 after the time that interval is preset.Therefore, according to the control system of electric automobile of the present utility model, may also include time block.
Time block can be connected with controller 50, the most lower electricity time of time block registration of vehicle, and after the most lower electricity time will reach the scheduled time, activation signal is sent with active controller 50, in order to low tension battery 30 is monitored and is controlled control switch 10 and voltage reduction module 40 by controller 50 to controller 50.Specifically, time block can be integrated in entire car controller, can pass through entire car controller active controller 50 after the most lower electricity time will reach the scheduled time.Wherein, time block can be timer, and the scheduled time can set according to the performance of low tension battery.
The control system of electric automobile of the present utility model is described below in detail with concrete work process.
In this utility model, electricity under vehicle can be judged according to the trailing edge of ignition key switch signal, time block can start timing when trailing edge occurs in ignition key switch signal, until stopping timing when rising edge occurs in ignition key switch signal, certainly the most lower electric time starting timing and being to the time period stopping timing vehicle.In this utility model, the scheduled time can be 15 days.It is to say, after the most lower electricity time of vehicle reaches 15 days, entire car controller active controller 50 can be passed through.
After controller 50 is activated, can monitor the open-circuit voltage of low tension battery 30, the open-circuit voltage of low tension battery 30 can represent the electricity of low tension battery 30, it will be appreciated that when the electricity of low tension battery 30 is relatively low, its open-circuit voltage is relatively low.In this utility model, if the open-circuit voltage of low tension battery 30 is higher than predetermined voltage, then closing control device 50；If the open-circuit voltage of low tension battery 30 is not higher than predetermined voltage, then controls switch 10 Guan Bi, and control voltage reduction module 40 and start, think that low tension battery 30 charges.
Should be appreciated that and close the stopping time at voltage reduction module 40, the voltage that controller 50 is monitored is the open-circuit voltage of low tension battery 30, and starts at voltage reduction module 40, and during charging for low tension battery 30, the voltage that controller 50 is monitored is charging voltage.Therefore, in this utility model, the voltage reduction module 40 open-circuit voltage with monitoring low tension battery 30 can be closed down in charging through after a period of time, if the open-circuit voltage of low tension battery 30 is higher than predetermined voltage, then judges charging complete.
Should be appreciated that the current electricity of low tension battery 30 is the lowest, the required charging interval is the longest.Therefore, in this utility model, the charging interval can be preset according to the current open circuit voltage of low tension battery 30.Current open circuit voltage and the corresponding relation in set charging interval of low tension battery 30 can refer to Fig. 2, because specific corresponding to relation is affected by electrokinetic cell and low tension battery 30 performance etc., only provide relation substantially at this, and inconvenience limits concrete numerical value.
Usually, accumulator is at the end of charging is just, and its open-circuit voltage can be more higher than actual value, and can be reduced to actual value at short notice.Therefore, in this utility model, when reaching the charging interval set in advance, also can close down voltage reduction module 40, and after low tension battery 30 is stood preset time period (such as, can be 10 minutes), the open-circuit voltage that monitoring low tension battery 30 is current, if the current open-circuit voltage of low tension battery 30 is less than predetermined voltage, then can set the charging interval again according to the open-circuit voltage that low tension battery 30 is current, and again charge for low tension battery 30 with this charging interval.Concrete charging process being initial value by open-circuit voltage is as shown in Figure 3, repeatable said process, until after low tension battery 30 is stood preset time period, the current open-circuit voltage of low tension battery 30 is higher than predetermined voltage, judge charging complete, now can control switch 10 disconnection, and control voltage reduction module 40 and close down.
Control system according to electric automobile of the present utility model, controller can monitor the open-circuit voltage of low tension battery after electricity under vehicle, and when judging that low tension battery electricity is relatively low according to open-circuit voltage, control switch Guan Bi and voltage reduction module is opened, so that low tension battery is charged.Thus, when vehicle does not powers on use for a long time, without human intervention, can automatically charge for low tension battery, thus when user reuses vehicle, the electricity of low tension battery can control and run by the normal of support vehicles, improves convenience and the Experience Degree of user's car.Meanwhile, it is capable to be prevented effectively from low tension battery to be in power shortage state for a long time such that it is able to extend the service life of low tension battery.
