Description
Technical field
The present invention relates to a kind of new energy car technical field, more particularly to a kind of new-energy automobile old and useless battery echelon utilizes
Management system, more particularly to its system attachment structure.
Background technology
The battery management system of existing lithium electricity fork truck is mainly for new battery.Echelon, which utilizes, considers directly transplanting new energy vapour
The battery management system of car.For new battery, brand-new exploitation battery management system cost is too high, it is difficult to industrialization.But directly
Transplant the battery management system of new-energy automobile, it may appear that the problems such as communication is restricted, electrical equipment mismatches.And the vehicle control of fork truck
System processed is different from passenger car, it is necessary to be directed to fork truck use environment and echelon battery feature, improves the original cell tube of passenger car
Reason system.
The content of the invention
In order to solve the above problems, the invention provides a kind of new-energy automobile old and useless battery echelon to utilize management system,
Including：
Battery module, the battery module are to unpack to screen from the new-energy automobile old and useless battery module of recovery to obtain；
Main control unit, the main control unit include digital core and some functional modules, and the digital core includes processor, interior
Deposit, counter, to carry out calculating and software, data storage, and send instructions to the functional module；Each mould of function
Block receives the instruction that the digital core is sent after calculating, performs control acquisition tasks；
It is described to be connected to from control unit on the battery module from control unit, information is collected to receive sensor, with chrysanthemum
The mode of chain communication is sent to the main control unit.
Further, a main control unit management is multiple from control unit.
When hybrid power new energy car battery bag is disassembled into simultaneously echelon utilization, its battery module negligible amounts, BMU controls
CMUs negligible amounts, and be that voltage platform is relatively low the characteristics of electri forklift energy-storage system, and capacity requirement is big, therefore required mould
Block number is more, i.e., CMUs is more, when the transmission gathered data of these CMUs high frequency times, random memory unit in BMU（Random
Access Memory, RAM）Space it is inadequate when, it may appear that the communication barrier.High-precision system pipes can be realized with multiple BMU
Reason, but cost is higher, it is not recommended that use.The mode of reduction data acquisition/transmission frequency can be taken, can still be managed with a BMU
More CMUs is managed, maintains relatively low cost.
Preferably, some functional modules include thermal management module, high-voltage safety module, power supply module, communication module, numeral
Signal input module, digital signal output modules, total voltage total current detection module, balance control system module, charging system
Module, global clock module, wherein communication module from control unit with mutually transmitting information.
Further, in addition to warning system, warning system is connected each other with main control unit by CAN, for sending
Charge alarm signal, high temperature alarm signal, balanced alarm signal, failure alarm signal, electrical equipment excess load alarm signal.
When battery management system monitors all kinds of failures such as Abnormal Insulation, electric voltage exception because sending fault warning in time,
Some failures should directly turn off main circuit relay, it is ensured that personnel and equipment safety.
Fork truck is when carrying out load startup, advancing the action such as lifting, it is necessary to momentary high power, it is meant that major loop electrical equipment electricity
Road need to carry great pulse current, if the high current duration is long, may cause electrical equipment damage, line in battery system
The danger such as beam overheat, the alarm of electrical equipment excess load should be sent.
The behaviors such as wait, pause are likely to occur during the normal order of classes or grades at school of fork truck, now driver turn key, low pressure control
It is electric under system processed, sleep signal should be transmitted to battery management system, if in the long period（Such as 20min）Without other responses, say
Bright order of classes or grades at school terminates, then turns off high-tension battery major loop relay, if driver turn key during this period, sends turning handle signal
（crank）, to electricity in low voltage control system, then BMS should be given to transmit wake-up signal, keep high tension loop normally closed.
When fork truck in the process of running, when colliding, travelling abnormal etc. all kinds of unexpected, driver should press jerk and open
Close, send emergent stop signal to BMS, turn off high-tension battery major loop relay, ensure personnel and equipment safety.
Dual consideration based on safety and cost, using the passive balanced mode of latter stage of charging, echelon battery is carried out balanced
Processing.As battery system is with recycling, necessarily there is the bad problem of different degrees of uniformity, indivedual battery cores during charging
Voltage reaches the upper limit, and the SOC of other most of battery cores is relatively low, now lithium electricity charging generator terminal output float charge voltage, power management
The high battery core electricity of voltage is bled off, gradually reduced using relay array control equalizing circuit by system by the form of heat
Voltage difference between battery core, realize battery balanced management.Therefore also require that every month will utilize special lithium when using echelon battery
Electric charger, charge for a long time at least once（More than 8 hours）, to ensure that the equalization problem of echelon battery is unlikely to influence
Its service life.
Battery bag is due to the performance difference between monomer, if charged always with plumbic acid charger（Or it is not filled with electric just direct
Use）, larger pressure difference occurs between the battery core in battery bag, and unbalanced phenomena will constantly dislike as battery charging and discharging circulates
Change, this is by strong influence battery life.Therefore design is when pressure difference is more than 150mV between battery core（Typically in discharge and recharge latter stage）,
Alarm signal should be sent, reminds user that battery is accessed into lithium electricity charger, allows battery management system to be carried out in latter stage of charging balanced
Safeguard.
Further, in addition to battery charge state is shown, to send the dump energy of battery module ratio to master control
Unit, when dump energy ratio is less than 10%, send the alarm signal of low battery.
The battery management system of passenger car is to battery charge state（State Of Charge, SOC）Computational accuracy ratio
The computational accuracy of fork truck dump energy is high, therefore continues to use original algorithm of battery management system, and SOC signals are uploaded into vehicle,
Moment informs truck driver residual power percentage.It is reply emergency situations, it is necessary in some specific shapes based on security consideration
Condition, which issues, send alarm signal:When dump energy is too low, and SOC is less than 10%, low battery alarm signal is sent.
Further, in addition to scram button, dormancy button is waken up, sends and stops signal by thinking manipulation or wake up dormancy
Signal is to main control unit so that main control unit turns off relay.
, can be real the invention provides a kind of for fork truck working environment and the battery management system of echelon battery self-characteristic
Existing a variety of security strategy guarantees, the effect for maintaining lower cost.
