Embodiment
Below in conjunction with accompanying drawing, the better embodiment of the common discharge control method of many power brick is described.
Present embodiment provides a kind of many power brick common discharge control method, can be used for the common control of discharge of multiple power brick of the equipment being provided with multiple power brick.Herein, for a kind of Horticultural power tool (specifically hay mover), the implementation step of the common discharge control method of many power brick is described.
Please refer to Fig. 1, the common discharge control method of many power brick comprises the following steps:
S110, establish a communications link between multiple power brick, wherein each power brick is all configured with control unit.In this step, each power brick is all configured with control unit, and control unit can be built in power brick.When multiple power brick is installed to after on hay mover, just set up communication connection each other between the control unit of each power brick, make each power brick all can be used for controlling the electric discharge of other power brick.
S120, using any one power brick as master control power brick.In this step, because each power brick is equipped with control unit, thus can any one power brick as master control power brick.When multiple power brick first time is mounted to hay mover, general using the power brick of first loading hay mover as master control power brick, after other power brick loads hay mover, establish a communications link respectively between master control power brick and other power brick, and also set up communication connection respectively between other each power brick.Being appreciated that not must using the power brick of first loading hay mover as master control power brick, and the power brick of other rear loading is also fine certainly as master control power brick.
S130, master control power brick detect all power brick and whether meet discharging condition.For the power brick of first loading hay mover as master control power brick, whether all power brick (comprising himself) of detection are met discharging condition by this first power brick.Meet discharging condition and refer to that the voltage of power brick is not less than default discharge voltage, and the temperature of power brick can not exceed the temperature of permission.
When hay mover is just started shooting, the temperature detected generally can not exceed standard, and now still needs to detect voltage, even if because just start shooting, the voltage of other power brick also may be had lower, do not meet discharging condition.In hay mover running, the control unit of master control power brick (i.e. the power brick of first loading hay mover) can monitor voltage and the temperature of each power brick in real time.
Because each power brick is equipped with control unit, each power brick all can use as master control power brick, therefore, when the control unit of the power brick of first loading hay mover as master control power brick lost efficacy, one in the power brick that other control unit can be selected in time not lose efficacy as new master control power brick.Like this, when carrying out common control of discharge to multiple power brick, the control of discharge of each power brick just can not rely on same control unit, would not occur that single control unit lost efficacy, cause the situation that multiple power brick all cannot be discharged.
S140, when having detected that power brick meets discharging condition, master control power brick control its electric discharge.In this step, all power brick meeting discharging condition are all added Spike train by master control power brick, and perform following steps: master control power brick detects the voltage matches meeting each power brick of discharging condition; Each power brick that master control power brick controls to meet discharging condition is discharged successively according to voltage levels and final common electric discharge.
May be there is inconsistent situation in the voltage meeting each power brick of discharging condition, discharge if now control them simultaneously, be then unfavorable for the normal work of hay mover.Therefore, each power brick controlling to meet discharging condition is discharged and final common electric discharge according to voltage levels by master control power brick successively.Always to have 5 power brick, but the power brick 1 only having 3 to meet discharging condition, power brick 2 and power brick 3 is example, and wherein voltage levels is followed successively by power brick 1> power brick 2> power brick 3.Now, master control power brick (is noted, master control power brick can not be one in above-mentioned 3 power brick, also one that can be above-mentioned be in 3 power brick) control power brick 1 first electric discharge separately, when power brick 1 and power brick 2 balance of voltage, master control power brick controls power brick 1 and power brick 2 is discharged jointly; When power brick 1 and the voltage of power brick 2 and the voltage of power brick 3 balance once again, master control power brick controls power brick 1, power brick 2 and power brick 3 and realizes common electric discharge.The quantity meeting the power brick of discharging condition be less than 3 or be greater than 3 time discharge flow path consistent when being 3 with quantity, repeat no more.
Multiple power brick herein should do the understanding of broad sense, and a power brick can be a battery, and can be the battery pack etc. of multiple battery composition, said circumstances affect the enforcement of the method for present embodiment yet.In addition, be appreciated that each power brick that then master control power brick controls to meet discharging condition is discharged simultaneously if master control power brick detects that the voltage of each power brick meeting discharging condition is consistent.
To sum up, the common discharge control method of above-mentioned many power brick, can use any one power brick as master control power brick, without the need to relying on single control unit, more effective to the control of discharge of multiple power brick.
Please refer to Fig. 2, also proposed a kind of many power brick power-supply system 200 implementing said method, comprise the first power brick 210, second power brick 220, the 3rd power brick 230, the 4th power brick 240, and be built in the first control unit 250 in the first power brick 210, the second control unit 260 be built in the second power brick 220, the 3rd control unit 270 be built in the 3rd power brick 230, the 4th control unit 280 be built in the 4th power brick 240.First power brick 210, second power brick 220, the 3rd power brick 230 and the 4th power brick 240 are connected in parallel in order to powering load.First control unit 250, second control unit 260, the 3rd control unit 270 and the 4th control unit 280 make aforementioned four power brick establish a communications link each other, and each like this power brick all can control the electric discharge of other power brick.Aforementioned four control units also can be placed in outside batteries, also do not affect each power brick and use as master control power brick.
It may be noted that in above-mentioned example, the quantity of power brick is 4, but not as limit, has more than 2 can implement the common discharge control method of aforesaid many power brick.Above-mentioned many power brick power-supply system 200, can use any one power brick as master control power brick, without the need to relying on single control unit, more effective to the control of discharge of multiple power brick.
The above embodiment only have expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
