Description of the drawings
Attached drawing 1 is the test connection diagram of the present embodiment.
Specific embodiment
Below in conjunction with the accompanying drawings and case study on implementation the invention will be further described：
A kind of test method of more battery packs, the present embodiment for testing 4 battery packs simultaneously, battery pack（PACK）Model：
S320-26。
Preparation includes：
Battery management system BMS（Hereinafter referred to as BMS）：It is for parsing and forwarding CAN data, send electric current to charging/discharging apparatus
Demand and control relay, BMS manage the charge and discharge process of battery pack by controlling disconnection and the closure of relay；
Charging/discharging apparatus：For battery pack in charge and discharge process output HIGH voltage and electric current；
Low-tension supply：For the circuit board power supply of circuit board, battery management system BMS in battery pack, low-tension supply obtains voltage and is
12V or 24V, every circuit board used in lithium battery management system（PCBA board）Be required to low pressure power supply come for
The startup of circuit board provides voltage and current,
Relay.
Low-tension supply is attached respectively with four battery packs, BMS；By four battery packs, charging/discharging apparatus respectively with
BMS carries out communication connection；Four battery packs are attached with charging/discharging apparatus；Each battery pack and charging/discharging apparatus it
Between, the output terminal of charging/discharging apparatus connect relay respectively.In the present embodiment：BMS leads to four battery packs, charging/discharging apparatus
Cross bus communication pattern（Hereinafter referred to as CAN）Realize communication.
The battery pack rule to be parsed is configured in BMS, such as in the present embodiment, needs to parse battery pack total voltage model
It encloses：242 ~ 371.8V, battery pack monomer voltage range：2.75 ~ 4.225V, battery pack temperature range：5 ~ 55 DEG C, in battery pack
The temperature range of circuit board：5~80℃.
The setting of BMS resolution rules could support up 20 rules, and per rule, setting has including interior：Enable whether, frame
ID（The frame ID of corresponding CAN data）, start bit and bit length（The data of 8 bytes of corresponding CAN data）, minimum value and maximum
Value（The range allowed according to the data that rule parsing comes out）, relay control.Wherein：Whether to enable the rule whether enabling
To parse the CAN data received from battery pack；Frame ID（The frame ID of corresponding CAN data）：The frame ID of CAN data frames, range
0x00000000 to 0x000007ff；Start bit and bit length（The data of 8 bytes of corresponding CAN data）：CAN data frame packets
The data of 8 bytes are included, the length of the data of each byte is 8, and a frame CAN data amounts there are 64 data（8 byte * are every
Byte 8）；Therefore the value of start bit is between 0 ~ 63, and 1<=(value of value+bit length of start bit)<= 64；Minimum value and
Maximum value（The range allowed according to the data that rule parsing comes out）：The range of data permission come out according to rule parsing, such as
The data that fruit parses be more than allow range, prompt error message, and according to below whether selection control relay come
Judge whether to act relay；Whether relay control acts relay for setting, if parse
Data can then control relay to disconnect beyond range as defined in rule；Such as unselected words, whether go beyond the scope regardless of data,
Relay is not acted, only prompt relevant error message.
In addition, BMS can detect 8 road temperature informations in itself, include per the setting of road temperature information in have：Enable with
No, minimum value and maximum value.Minimum value and maximum value if the setting that the value of the road temperature information exceeds are represented whether enabling
Range after whether to disconnect master relay.The 8 tunnel temperature controls of BMS are the work(of 8 tunnel temperature detections that BMS itself has
Can, it needs to distinguish with the temperature information of the battery pack in BMS resolution rules and develop；Because the circuit board in each battery pack also has
The function of standby temperature detection, therefore the temperature information of battery pack is the state of temperature for reacting single battery packet, and the 8 tunnel temperature of BMS
Degree can connect temp probe, and user is allowed to be placed into desired position according to the requirement of oneself and carries out monitoring temperature, such as can be with
Each wiring point that charging/discharging apparatus connects with battery pack is placed on to detect temperature.
Start battery management system BMS, BMS after the CAN data of battery pack are received, it can be by four battery packs
CAN data summarizations to passing through CAN all the way together（The CAN_LMU0 and CAN of charging/discharging apparatus communication is with all the way）Data are sent out
It sends out, is parsed for the data of host computer.Since in test process, the data frame that each battery pack is sent is the same,
If without the conversion of data, host computer can generate data collision during data are parsed and can not effectively parse number
According to, therefore, it is necessary to during CAN data summarizations, by the frame ID for the CAN data do not gone the same way plus respective setting value into
After be sent to host computer, then can parse the data of four battery packs during host computer parsing, forwarding is set per road CAN
It puts and includes whether to enable, the value that frame ID is added during forwarding.When be resolved to battery bag data exceed the rule range
When, then error message is prompted, control relay disconnects.
BMS can acquire the electric current of each battery pack and the total current of charging/discharging apparatus by hall band in itself.BMS can be with
The charge and discharge of four battery packs are managed by controlling disconnection and the closure of relay, when the model for thering is battery bag data to exceed rule
When enclosing, the corresponding control relay of the battery pack disconnects；When the output current value of charging/discharging apparatus goes beyond the scope, charge and discharge are set
Standby corresponding relay disconnects, and charging/discharging apparatus stops electric current output.
BMS to charging/discharging apparatus send needed for electric current communication data, charging/discharging apparatus is according to the communication data pair of reception
Four battery packs carry out charge and discharge.BMS can set what the BMS of charged state and discharge condition was sent to every road battery pack respectively
CAN data informations.
In the present embodiment：Four battery packs are simultaneously to carry out charge and discharge together, therefore four battery pack total voltages and list
The voltage value of a battery pack is the same.The manufacture of a general battery pack is all by multiple battery core elder generations and is unified into a module,
Then the battery pack that multiple block coupled in series form together, the monomer voltage of battery pack refer to the mould that multiple battery cores compose in parallel
The voltage value of block, the total voltage of single battery packet are the total voltage values for the battery pack that multiple block coupled in series get up.
In charging process, the low battery pack elder generation closing relay of voltage starts to charge up, when some battery pack voltage and
Close the minimum voltage of the battery pack of relay difference be less than setting relay be closed pressure difference, then close the battery pack after
Electric appliance charges, if after multiple battery packs close relay, because some battery pack is led to the problem of, leads to the battery
Packet voltage ramps, when the voltage that the battery pack voltage rises is more than more than the difference of battery pack minimum voltage to charge together
Relay disconnects pressure difference, and battery pack corresponding relay in Ze Gai roads disconnects.In discharge process similarly.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and implement according to this, and it is not intended to limit the scope of the present invention.It is all according to the present invention
The equivalent change or modification that Spirit Essence is made, should be covered by the protection scope of the present invention.
