Boat ability.The invention provides a kind of detection of electrokinetic cell system and maintaining method, can effectively reduce electrokinetic cell bag and exist
Potential safety hazard in transportation and the installation time extended by electrokinetic cell bag failure, reduce caused appearance in storing process
Amount loss, so as to effectively reduce electrokinetic cell bag fault rate and capacitance loss, substantially increases the utilization of electrokinetic cell bag
Efficiency, transportation safety is ensured.
The content of the invention
The problem of the technical problem to be solved in the present invention is the detection and maintenance of electrokinetic cell system.
In order to solve the above-mentioned technical problem, the utilization ratio of electrokinetic cell is improved, extends its service life, reduction stored
Caused capacitance loss in journey, and effectively reduce potential safety hazard of the electrokinetic cell bag in transportation and because of electrokinetic cell bag
Failure and the installation time extended, the present invention propose detection and the maintaining method of a kind of electrokinetic cell system.
The present invention is specifically to be realized with following technical scheme：
Specifically, after power-up initializing, battery management system carries out self-test, whether there is failure in detecting system, detects
Content includes：Insulation resistance value, pressure difference and temperature etc..Battery management system is installed on inside electrokinetic cell, can gather each power
The real-time status of battery modules and single battery core, and the real-time status is sent to the host computer of battery management system, monitoring
The fault message and information about power of electrokinetic cell.If there is failure, failure is just reported to the host computer of battery management system,
Failure is investigated again.Malfunction elimination finishes and then secondary power-up initializing.If system is normal, it is possible to insertion charging
Rifle, battery management system prepare shake hands being connected with charging pile.
Further, after inserting charging gun, battery management system shake hands being connected with charging pile, if connection of shaking hands is lost
Lose, then explanation still suffers from failure, it is necessary to carry out malfunction elimination.If successful connection is shaken hands, by the upper of battery management system
Machine obtains the information about power of battery, and dump energy in battery judges to survey battery and should charge, discharge or direct
Storage.
Further, if dump energy be more than it is at full charge when 30% and less than it is at full charge when 50%, so that it may
With by survey battery be directly put in storage, if dump energy be more than it is at full charge when 50%, just surveyed battery is discharged, such as
30% when fruit dump energy is less than at full charge, just surveyed battery is charged.
Specifically, if surveyed battery needs to discharge, entrucking and consumed energy, electricity and vehicle detection can finish as early as possible
Afterwards, finished product garage, convenience in transport can be entered simultaneously with vehicle.
Specifically, if surveyed battery needs to charge, two ways can be used to carry out.First method is by vehicle-mounted
Charger, charging socket and alternating-current charging pile charge to battery, and second method is by charging socket and DC charging
Stake is charged to battery.
Further, charge or discharge complete and then it is secondary by dump energy information reporting to the upper of battery management system
Position machine, if dump energy be more than it is fully charged when 30% and less than it is fully charged when 50%, it is possible to the battery is put in storage.
The present invention judges power by the handshake operation of battery management system self-test and battery management system and charging pile
Can battery whether there is failure, be put in storage safely.In the present invention, battery management system is installed on the inside of electrokinetic cell bag,
For gathering the real-time status of each power battery module and single battery core, power is monitored by sending state in real time to host computer
Battery failures information and information about power.
Using above-mentioned technical proposal, a kind of detection of electrokinetic cell system of the present invention and maintaining method, have such as
Lower beneficial effect：
1) present invention is by fault detect, can effectively reduce potential safety hazard of the electrokinetic cell bag in transportation and because
Electrokinetic cell bag failure and the installation time extended, significantly reduce electrokinetic cell bag fault rate；
2) by being safeguarded to battery, caused capacitance loss in storing process is reduced, substantially increases power electric
Chi Bao utilization ratio, has ensured transportation safety.
