Technical field
The present invention relates to a kind of battery management system (BMS), configurable battery management system of particularly a kind of node address and concrete management method thereof.
Background technology
Battery management system (BATTERY MANAGEMENT SYSTEM abbreviates BMS as) is the tie between battery and the user, mainly to liking secondary cell.Some shortcomings below secondary cell exists are few like stored energy, the life-span short, problem is used in connection in series-parallel, safety in utilization, battery electric quantity estimation difficulty etc.The performance of battery is very complicated, and dissimilar battery behaviors also differ greatly.Battery management system (BMS) major function comprises: the state-of-charge (State of Charge, i.e. SOC) of accurately estimating power battery pack; In battery charge and discharge process, gather terminal voltage and temperature, charging and discharging currents and the power brick total voltage of every battery in the accumulator of electric car group in real time, prevent that battery from overcharging or the overdischarge phenomenon; Be the cell equalizing charge, make each battery in the battery pack all reach balanced consistent state.These measures all are intended to improve utilance, the extending battery life of battery.
The storage battery of electric automobile is normally connected, because the characteristic of dispatching from the factory of cell is inconsistent, plays an important role so above-mentioned battery management system is brought into play for the performance of electric automobile.
Fig. 1 is the BMS system construction drawing of the electric automobile of a typical prior art, like figure, system mainly by a master board, n from control board (also claiming monitoring means) and display module etc.Mainly be responsible for the measurement of information such as voltage, electric current, working temperature to the single battery of its monitoring from control board; And with the data that collect through the CAN bus (abbreviation of the Controller Area Network of controller local area network; It is one of most widely used fieldbus in the world; In the world in a big way in, the CAN bus protocol has become the STD bus of Computer Controlled System for Vehicle and built-in industrial control area net) be transferred to master board; Master board is responsible for handling the battery status information that collects from control board, and gives equipment such as display module, charger and entire car controller with process result through outside CAN bus transfer.
This battery management system, owing to relate to communicating by letter of master controller and a plurality of slave controllers, so brought the problem of communication contention aware.The mode that battery management system adopted that solves communication contention aware at present mainly contains two big types: one type is that each slave controller is used the Different software code, the bus sign (bus ID) that static configuration is different; Another kind of is that mode through hardware or software is elder brother's slave controller dynamic assignment bus ID.First kind method need be developed the software code with different I D, and the complexity of software is higher.The second class methods efficient and cost are lower.
Described second class methods of relevant preamble; Open in the Chinese patent 200910249544.0 " distributed battery management system and mark distributing method thereof "; System is electrically connected master controller with a slave computer; This slave computer and other slave computers are electrically connected in series successively, master controller is given each slave computer allocation identification successively through the mode that activates the slave computer that is in series successively again.
In this technical scheme, a plurality of slave computers (being equivalent to slave controller) needs are connected successively, and the construction complexity is high, cost is high; And slave controller only just can be activated after last one the slave controller of adjacent electrical connection distributes the address with it and starts working; And the address of the slave controller that is activated is through obtaining to the master controller application; It is to be operated in the address configuration process that the same time has only a slave controller; Not only overall system efficiency is lower, and in some series circuits the situation of disconnection is arranged, and will cause follow-up one or more slave controller can't operate as normal.Simultaneously, the process that this battery management system all must carry out the primary address configuration when powering in each system has prolonged the initialization time of whole system undoubtedly.
Other has Chinese patent 200810021154.3 " distributed battery management system and management method thereof "; This invention is through at the external wire jumper circuit of acquisition module (also being equivalent to slave controller), utilizes the wire jumper circuit state to give corresponding C AN bus address for each acquisition module.This prior art has been introduced a plurality of wire jumpers as the hardware separator; Though solved the problem of system communication conflict effectively; But be not difficult to find that the quantity of the wire jumper circuit of this invention will increase along with the increase of acquisition module quantity, increase the hardware complexity of system; Let the hardware line become complicated, the quantity of the general input/output port (GPIO) of its shared microprocessor (MCU) also will increase.And it is different to need to rely on all hardware jumper states in the entire work process, and the setting of wire jumper can only rely on manpower to accomplish, and error rate is high.Wire jumper more likely in the course of the work also maybe be because vibration etc. be former thereby variation causes whole system to be made mistakes.
Summary of the invention
The objective of the invention is deficiency, a kind of battery management system communication contention aware problem, simple in structure, with low cost and method that can solve between the master-slave controller is provided to the described prior art of background technology.
For this reason, technical scheme of the present invention is such:
A kind of battery management system; Comprise master controller, slave controller, master controller is through a plurality of slave controllers of inner CAN bus control connection, and each slave controller is controlled a battery pack; Master controller also connects external equipment through outside CAN bus; It is characterized in that: also comprise a wire jumper circuit module and nonvolatile storage, wire jumper circuit module control connection slave controller, the mode of operation of decision slave controller; Nonvolatile storage is connected with slave controller, the slave controller address that memory distribution arrives.

Embodiment
Like Fig. 2, battery management system of the present invention comprises master controller 1, a plurality of slave controller 2, and master controller 1 is electrically connected with a plurality of slave controllers through inner CAN bus, battery pack 3 of control of each slave controller 2 correspondence.Master controller 1 connects external equipment through outside CAN bus; External equipment comprises display module 4, charger 5, entire car controller 6, also particularly including wire jumper circuit module 7 and nonvolatile storage 8, wire jumper circuit module control connection slave controller; Wire jumper circuit module 7 provides 0 and 1 two kind of logic; The mode of operation of decision slave controller is in address allocation pattern or is in normal operation mode, as, plug jumper cap and show and be in the address configuration pattern; Jumper cap breaks off and shows normal mode of operation, and vice versa.Nonvolatile storage 8 is connected with slave controller 2, the work address of the slave controller that memory allocation arrives.
Concrete workflow such as Fig. 3 of the address assignment of native system and normal operation mode.
Step 2, read wire jumper information, which kind of mode of operation the decision slave controller gets into, and then jumps to step 3 and gets into the address configuration pattern and carry out for plugging state like, jumper cap, and jumper cap is that off-state then forwards step 4 to and gets into the normal mode of operation execution.
Step 3, address configuration mode of operation comprise following several steps:
A, with before pre-configured bus address other slave controller on the CAN bus send " the address statement frame " of this address of statement.
B, reception CAN frame data, and resolve the frame data of receiving.
The frame data of C, the address occupied " this address just is used " that judges whether to receive that this slave controller is stated in step 2 (A).If the address is occupied, then the next available address of selective sequential and writes (like EEPROM) in the nonvolatile storage with this address as the pre-configured bus address of this slave controller from address pool, forwards step 2 afterwards to.If the address is unoccupied, this address is write in the nonvolatile storage, and forward step 2 continuation operation to.
Step 4, normal mode of operation comprise the steps:
A, from nonvolatile storage (EEPROM), read this slave controller bus address that disposed when dispatching from the factory, this address is participated in the address of bus communication as this slave controller.
Information such as B, collection voltage, temperature are carried out the computing of related data, and are judged whether to exist fault.
The Frame of receiving on C, the parsing CAN bus responds corresponding frame data according to different frames on bus, like the remote frame of response master controller request information of voltage.
D, judge whether to have on the bus and receive " address statement frame " identical with self address, as receive, then on bus, send the frame data of " this address just is used ",, then continue the execution of next step if do not have.
Other tasks of E, execution slave controller are carried out equilibrium control etc. like the battery module that this slave controller is measured.
F, repeating step 4 (B) are to step 4 (E).
In the address configuration process; At first the wire jumper circuit with slave controller is in the jumper cap state of plugging; And all are needed linking same CAN bus from control board and getting on of configuration address; Successively jumper cap is extracted from slave controller at set intervals, slave controller has just been accomplished the address configuration process successively and has been got into normal operation mode of operation, then according to the system configuration of Fig. 1; The inside CAN bus that is connected with all slave controllers is linked to each other with master controller, and the entire cell management system just can operate as normal.And behind the system cut-off; When starting shooting again Deng next time; Because the bus address of slave controller configuration has before been write in the nonvolatile storage, these slave controllers only need take out their bus address separately from memory just can participate in bus communication by ensuring escapement from confliction.
The explanation of giving one example:
One has three slave controllers and needs configuration address in the battery management system.So, at first the CAN bus of these three slave controllers is linked together, and all inserted the jumper cap of the wire jumper circuit of three board (insert good and pull up be two kinds of different logical).Finish after the preparation; Three board is powered on and according to flow performing program shown in Figure 2, suppose total " 10 " in the slave controller address pool " 11 "; " 12 " three addresses can supply to distribute; This moment, three board all was in the address configuration pattern, and all on bus, was stating the bus address of address " 10 " for oneself, because do not use this bus address to be operated in the slave controller under the normal operation mode this moment; So do not have the frame data generation that address " 10 " " just is being used frame " on the bus, these slave controllers just can be stated one " address statement frame " at set intervals on bus.
The jumper cap of the wire jumper circuit of a slave controller is wherein pulled out; It will use address " 10 " to get into normal mode of operation work; And the frame data of " the address statement frame " response one " this address just is used " of the address " 10 " that other two slave controllers are sent; Two slave controllers receiving these frame data just can be selected statement address separately on bus again, address " 11 "; Same since do not use this moment this bus address be operated under the normal mode of operation from control board, these two slave controllers will continue use address " 11 " and on bus, state the address, and be operated under the address configuration pattern.
Wherein a jumper cap that is operated in the slave controller under the address configuration pattern pulls out again; He will use address " 11 " to get into the normal operation mode operation; And the frame data of " the address statement frame " response one " this address just is used " of the address " 11 " that will send the 3rd slave controller; So after the 3rd slave controller received the frame data that address " 11 " just is being used, it will select its address of statement on bus again, address " 12 ".
After last jumper cap with the 3rd slave controller is pulled out; Three slave controllers have just all been accomplished the process of address configuration; Because these bus addresss have been written in the nonvolatile memory, when starting shooting next time, just can directly from memory, read bus address separately.
