Background technology
At present, a lot of lithium battery management systems on the market must close self circuit when non operating state completely for reducing power consumption, thus user needs the special starting switch first opened in battery pack in use, then normally could use external equipment, described external equipment can be garden instrument or electric tool.Due to above-mentioned lithium battery management system, need to arrange special switch on the battery pack to realize opening and closing, complicated operation, and cost is higher.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of lithium battery management system and control method thereof of simple to operate, low-power consumption.
Described lithium battery management system employing technical scheme is: a kind of lithium battery management system, comprises the battery pack be made up of some lithium cells for providing power; And for controlling the power brick output switch that described battery pack output current is turned on or off, described power brick output switch is open type switch; And for controlling the battery management system control unit of described power brick output switch closure or openness; And the output resistance to be arranged in parallel with described power brick output switch.
Preferably, described output resistance employing resistance is the resistance of kilo-ohm level.
The control method of described lithium battery management system is:
Step one:
The power brick access external equipment of described lithium battery management system will be had;
Step 2:
When opening the starting switch of described external equipment, the control circuit of external equipment is activated and exports one and wakes control signal up to described battery management system control unit;
Step 3:
Receive the battery management system control unit that wakes control signal up by output switch controlling signal to described power brick output switch so that open type switch is closed;
Step 4:
When the power brick and external equipment with described lithium battery management system being disconnected, described closed open type switch recovers normally open, and described battery management system control unit is in buttoned-up status.
The present invention is by by the access of the power brick and external equipment with described lithium battery management system or disconnect the unlatching or the closedown that realize lithium battery management system, achieve the function of special switch of the prior art when user operation external equipment, there is beneficial effects such as reducing costs, easy to operate.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the schematic diagram of lithium battery management system of the present invention;
Fig. 2 is the flow chart of lithium battery management system control method of the present invention.
Embodiment
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the schematic diagram of lithium battery management system of the present invention.As shown in Figure 1, external equipment of the present invention specifically refers to by the direct current garden instrument of lithium battery Packet driven or direct current electric power tools, specifically, can be the electric tool series products such as the garden instrument series products such as hay mover, grass-mowing machine, pruner, hair-dryer, or electric drill, electric circular saw, reciprocating saw.Therefore, the battery pack be made up of some lithium cells shown in Fig. 1, battery management system control unit, power brick output switch and output resistance are all be arranged on the assembly in lithium battery bag, when lithium battery bag access external equipment, lithium battery management system of the present invention can work; When lithium battery bag and external equipment disconnect, namely lithium battery management system of the present invention quits work.Described lithium battery management system, specifically comprises: for providing the battery pack be made up of some lithium cells of power; And for controlling the power brick output switch that described battery pack output current is turned on or off, wherein, described power brick output switch is open type switch; And for controlling the battery management system control unit of described power brick output switch closure or openness; And the output resistance to be arranged in parallel with described power brick output switch.
Specifically, when lithium battery bag access external equipment, because described power brick output switch disconnects, described battery pack has kilo-ohm output resistance of level resistance value by one provides one by the cell circuit of output resistance to external equipment, the loop namely formed by battery anode → external equipment → output resistance → battery electrode.By this loop, the electric current of battery will respectively flow through external equipment and output resistance, until the input capacitance voltage of external equipment inside is consistent with battery voltage, now external equipment just can obtain the startup energy that can start shooting.But same because the existence of output resistance, before power brick output switch is not closed, peripheral hardware all cannot obtain the electric current that can normally work.
Only have when user is when opening the starting switch of external equipment, the control circuit of external equipment is activated and exports one and wakes control signal up to described battery management system control unit, then the battery management system control unit that wakes control signal up is received by output switch controlling signal to described power brick output switch, and then open type switch is closed, therefore output resistance is made to be shorted, realize battery pack to the function of external equipment continued power, external equipment can normally work.
Fig. 2 is the flow chart of lithium battery management system control method of the present invention.The control method of described lithium battery management system is:
Step one: will the power brick access external equipment of described lithium battery management system be had;
Step 2: when opening the starting switch of described external equipment, the control circuit of external equipment is activated and exports one and wakes control signal up to described battery management system control unit;
Step 3: receive the battery management system control unit that wakes control signal up by output switch controlling signal to described power brick output switch so that open type switch is closed;
Step 4: when the power brick and external equipment with described lithium battery management system being disconnected, described closed open type switch recovers normally open, and described battery management system control unit is in buttoned-up status.
In sum, the present invention is by by the access of the power brick and external equipment with described lithium battery management system or the unlatching or the closedown that disconnect realizing lithium battery management system, achieve the function of special switch of the prior art when user operation external equipment, there is beneficial effects such as reducing costs, easy to operate.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
