Description

A kind of implementation method of power battery backup combination system
Technical field
The present invention relates to battery technology field, relate in particular to power battery backup combination system and its implementation of being applied in electric automobile field.
Background technology
Electric automobile application or other need the application of electrokinetic cell all to need electrokinetic cell as the power energy-storage units of system, even in some systems, this energy-storage battery unit is the unique energy source of system, therefore very high to the reliability requirement of this energy-storage battery unit.In some applications, there are some problems in single stored energy power battery unit.Meanwhile, system is considered, in the application system of backup, not only will consider the backup solution of current system, is also needed the extensibility of taking into account system simultaneously.In existing electrokinetic cell system application, electrokinetic cell can be used separately as unique energy-storage units, even if having the occasion of many electrokinetic cell application, the energy storage requirement that each electrokinetic cell unit is also complete independently whole system.When any one electrokinetic cell breaks down or during other problems, this electrokinetic cell will quit work, and then cause this electrokinetic cell that energy output and stored energy function cannot be provided to extraneous equipment.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of assurance whole system reliably working, the independent operating of each energy-storage units and backup each other machine-processed power battery backup combination system and its implementation.
The technical problem to be solved in the present invention is achieved through the following technical solutions: a kind of power battery backup combination system, comprise at least two power supply unit bodies, between described power supply unit body, by CAN control bus, undertaken interconnectedly, on power supply unit body, be equipped with information output interface; Described power supply unit body comprises electrokinetic cell unit and battery management system unit.
The present invention also provides the implementation method of above-mentioned power battery backup combination system, and implementation step is, A, power battery backup combination system are connected low-tension supply and started working, and the battery management system unit in power supply unit body carries out system initialization; After B, initialization are complete, each power supply unit body is sent and is usingd own code clerk as the CAN infomational message of source address and the priority arbitration request of encoding by CAN control bus; C, in setting-up time, the coding priority of the coding priority arbitration request of other power supply unit bodies that any one power supply unit body is received is during all lower than oneself coding priority, this power supply unit body is as the master control system of whole power battery backup combination system, and the power supply unit body of other low priorities is as from control system.In described step C, coding priority is controlled all power supply unit bodies for the battery management system unit in the highest power supply unit body, completes the information output of external interface.
Compared with prior art, electrokinetic cell is not independent one group, but power battery backup combination system, it consists of together two groups or more power supply unit body, to complete the Redundant Control demand that backups each other.As mutually redundant any one group of power supply unit body, can there is oneself independently control system, can in the system of only having one group of power supply unit body, use, realize the Scalable Performance of system simultaneously.When existing many group power supply unit bodies to use simultaneously, power supply unit body is by the employing preferential controlling mechanism of encoding: each group power supply unit body has own battery to encode, when accumulator system brings into operation, after each power supply unit body completion system initialization, by CAN bus, send oneself coding priority arbitration request, each power supply unit body goes to monitor the coding priority arbitration request that other power supply unit body sends over simultaneously, when power supply unit body at the appointed time, in the coding priority arbitration solicited message listening to, while not intercepting the request of encoding preferential than oneself, this power supply unit body becomes the main control unit of each power supply unit body, when power supply unit body at the appointed time, when the coding that listens to power supply unit body has precedence over oneself, this power supply unit body is as from control module, ensuing in service, receive only and carry out the order of main control unit, jointly to complete output and the demand for control of power battery backup combination system.When system only has one group of power supply unit body to use, this power supply unit body is the requests for arbitration of monitoring less than other power supply unit bodies at the appointed time, and then this group power supply unit body can initiatively enter automatic control pattern, completes the energy storage output and control of this system.
Accompanying drawing explanation
Fig. 1 is power battery backup combination system principle sketch of the present invention.
Embodiment
For the ease of those skilled in the art's understanding, below in conjunction with embodiment and accompanying drawing, the principle of the invention is described in further detail:
, comprise PACK1.。。。PACKn power supply unit body, wherein, n >=2, are undertaken interconnectedly by CAN control bus between described power supply unit body, be equipped with information output interface on power supply unit body; Described power supply unit body comprises electrokinetic cell unit and battery management system unit.PACK1 is encoded to No. 1, and PACKn is encoded to n (n >=2) number.Number littlely, priority arbitration is higher.
When system starts to work on power, PACK1 and PACKn can work and the initialization task of completion system simultaneously.After completion system initialization task, n PACK can be sent and be usingd own code clerk as the CAN infomational message of source address by CAN control bus, sends the priority arbitration request of encoding simultaneously.
When in setting-up time, for example, in 1 second, the coding priority of the coding priority arbitration request of other PACK that any one PACK receives is during all lower than oneself coding priority, the highest during the coding priority of this PACK, it will be as whole system master control system, and the system of all low priorities is as from control system.In illustrated system, the coding priority of PACK1 is high, and the coding priority of PACKn is low, and PACK1 will be as master control system, and PACKn, as from control system, is then controlled PACK1 and PACKn by PACK1, completes the information output of external interface.
The present invention proposes the preferential controlling mechanism of a kind of coding, solves the backup each other system applies demand of formula of electrokinetic cell.And current driving force battery is all generally to use as a separate unit in reality use, there is very strong independence, determined like this less stable of system.The present invention considers that system backup needs the composition of a plurality of power supply unit bodies, not only to consider the independence of power supply unit body, power supply unit body is in the extendability of use procedure simultaneously, by encoding, preferential controlling mechanism can back up by resolution system, realize battery back mechanism, and then improve redundancy and the stability of battery energy storage system.
