Description
Technical field
This utility model relates to a kind of power battery pack structure.
Background technology
Existing power battery pack is that the structure of set of cells is simple with occupation mode, and management method is substantially free of by the series connection of single battery and parallel combination are formed according to user's voltage requirements.If now having a batteries to go wrong can cause that whole string set of cells cannot use, so can cause originally some still operable battery cannot use, not only waste resource, also can reduce the service efficiency of set of cells.
Utility model content
Technical problem to be solved in the utility model is the power battery pack structure providing a kind of every batteries to can be used alone, other batteries are not impacted for above-mentioned prior art.
The technical scheme that the above-mentioned technical problem of this utility model solution adopts is: a kind of power battery pack structure, it is characterized in that: include multiple cell basic unit being connected in series with each other, each cell basic unit includes the battery that more piece is connected in parallel with each other, every batteries is respectively connected with power management module, this power management module includes the voltage for gathering battery, electric current, the information acquisition module of temperature, the control module that is connected with information acquisition module and the relay switch that battery is connected can be disconnected with cell basic unit, relay switch is connected with controlling module, being turned on and off of relay switch is controlled by controlling module, so that this batteries departs from from cell basic unit or accesses cell basic unit.
As improvement, described cell basic unit also includes cell basic unit and controls switch, and this cell basic unit controls switch and is connected with all cell parallels being connected in parallel, it is possible to rejected from power battery pack by monoblock cell basic unit.
Improving, described power management module also includes can with the communication module of outer net communication, and this communication module is connected with administrative center again.
Compared with prior art, the utility model has the advantage of: in cell basic unit in multiple batteries parallel with one another, as long as there being a batteries energy normal operation, so monoblock power battery pack just can maintain normal operation, every batteries can be independently from, not affecting other batteries, thus improving the reliability of whole power battery pack, improving service efficiency；Every piece of provisioned power management module of battery, this batteries can be made this batteries to be departed from from cell basic unit when breaking down, do not affect the use of monoblock power battery pack, after damage battery altering is spec battery, can again access again cell basic unit.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment medium power set of cells.
Fig. 2 is the eliminating flow chart of fail battery in this utility model embodiment；
Fig. 3 is the recovery flow process of fail battery in this utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
Power battery pack structure as shown in Figure 1, it includes multiple cell basic unit 1 being connected in series with each other, each cell basic unit includes the battery 13 that more piece is connected in parallel with each other, every batteries is respectively connected with power management module 11, this power management module includes the voltage for gathering battery, electric current, the information acquisition module (not shown) of temperature, the control module (not shown) that is connected with information acquisition module and the relay switch 14 that battery is connected can be disconnected with cell basic unit, relay switch is connected with controlling module, being turned on and off of relay switch is controlled by controlling module, so that this batteries departs from from cell basic unit or accesses cell basic unit；Described cell basic unit 1 also includes cell basic unit and controls switch 12, and this cell basic unit controls switch and is connected with all cell parallels being connected in parallel；Power management module also includes can with the communication module of outer net communication, and this communication module is connected with administrative center by bus 2.
It addition, the power management module being connected with every batteries has independent Position Number.
The management of power battery pack is included in eliminating flow process when power battery pack normally uses to fail battery by described power management module, and its method is, shown in Figure 2:
Step 1, information acquisition module gather the voltage of battery, electric current, temperature and pass to control module；
Step 2, control module gather according to information acquisition module cell voltage, electric current, temperature signal, enter following judgement: if any one parameter of the voltage of battery, electric current, temperature occurs abnormal, all judge that this batteries breaks down, and this fault message is passed to administrative center, the Position Number of administrative center's prompting fail battery；
Step 3, the module that controls control relay switch according to the fault message of battery and open so that this batteries departs from from cell basic unit.
The management of power battery pack is also included in the recovery flow process to fail battery by described power management module, and its method is, shown in Figure 3:
Step 1, Position Number according to fail battery, find fail battery；
Step 2, this fail battery is labeled as spec battery, and check the voltage of this battery, electric current and temperature parameter, in the voltage of this battery, electric current and temperature, any one parameter occurs abnormal, this battery of labelling is fail battery again, and return step 1 and reenter recovery flow process, if performing to recover flow process number of times be still labeled as fail battery more than N and this battery, then this battery thoroughly damages；As all normal in the voltage of this battery, electric current and temperature these three parameter, after the time delay M second, check again for the voltage of this battery, electric current and temperature these three parameter, if the voltage of this battery, electric current and temperature these three parameter are still normal, then this battery of labelling is spec battery, recovering enabling this battery, wherein the value of N is 3～12；The value of M is 3～12.
So, in cell basic unit, every batteries can be used alone, and does not affect other batteries, single battery can detachment system after damaging, do not affect the performance of monoblock power battery pack, and possess prompting function and can change by convenient for maintaining, only single battery need to be processed；If all batteries lost efficacy in whole cell basic unit, it is also possible to control switch 12 by cell basic unit and this cell basic unit control switch 12 is shielded out power battery pack, make power battery pack subnormal voltage operation, it also it is a kind of guarantee of reliability.On some owing to voltage, electric current, temperature fluctuation etc. produce the battery of impact, failture evacuation can also be carried out, it is ensured that some misjudged batteries can be continuing with owing to controlling module.And every piece of provisioned power management module of battery is connected with administrative center by bus, administrative center can it will be seen that the service condition of every piece of battery by bus, the average current of set of cells can be calculated, the relevant parameters such as voltage, conveniently single battery situation in power battery pack is judged, precise positioning convenient for maintaining can also be carried out for the battery damaged.
