Description
Technical field
The present invention relates to BMS technical fields, and in particular to a kind of integrated form BMS+GSM all-in-one machines.
Background technology
Battery management system (BATTERY MANAGEMENT SYSTEM) battery management system (BMS) BMS battery system customs
Referred to as battery nurse or battery house keeper mainly aim at intelligent management and safeguard each battery unit, prevent battery from going out
Existing overcharge and overdischarge, extend the service life of battery, monitor the state of battery.If asking new-energy automobile manufacturer most
What is be afraid of is whatIt people can much may answer " spontaneous combustion ".Really, electric vehicle spontaneous combustion is not only the bad dream of enterprise, and entire
The bad dream of industry.To find out its cause, in addition to battery problem itself, the battery management system (Battery of battery operation is controlled
Management System, abbreviation BMS) also play key effect.In a way it can be said that Chinese lithium battery it is horizontal
Through not low, even more the first in the world, many advanced production lines are import on a manufacturing scale, and hardware facility already belongs to first intake
It is flat.But why many batteries with 1 year just dying, insider thinks, an important short slab is still in BMS.
" with for battery, dying, practical battery core or good, this exposure is control system weakness." BMS, usually claimed in the industry
For " brain " of new energy car battery, three big cores of new-energy automobile are collectively formed with power battery pack, whole-control system
Heart technology.Due to its in new-energy automobile industry distinctive importance, increasingly " pursued " by the industry, while also containing
Huge commercial opportunities.The country first appears BMS researchs at 2000 or so, and product market really occurs and probably also just there was only 4 or five years
Time.The immature property of BMS technologies becomes new-energy automobile and further develops the bottleneck urgently broken through.China BMS products at present
Market management also in " unordered " stage, the not no mandatory examination criteria of unification of the motherland.Meanwhile China's BMS product technologies
There is also very big gaps with foreign countries in terms of ability and design concept, it is difficult to undertake Future New Energy Source automobile practical application request.Peace
Quan Lingyu " psychological comfort "." plug-in hybrid-power automobile, pure electric automobile to putting into demonstrating running will all install vehicle
Running technology realtime monitoring system will especially reinforce the monitoring to power battery and fuel cell operation status."2011
On August 18, new-energy automobile Demonstration And Extension of four ministries and commissions such as the Department of Science and Technology, the Ministry of Finance, Ministry of Industry and Information and Committee of Development and Reform in joint publication
" safety enables " ---《About the letter for reinforcing energy saving and new-energy automobile Demonstration And Extension management of safe operation》In so emphasize.Although
China has certain technological reserve advantage in fields such as power battery, motor and control systems, but these technical advantages are parts
, it is temporary, there is still a need for tackling key problem in terms of integrated technology." " safety enable " vehicle running technology realtime monitoring system for being sayed
System is exactly BMS, it is of equal importance with power battery pack quality, is all played a crucial role for evading cells burst.Away from
After issuing nearly 2 years from above-mentioned policy, how the BMS current situations in China are again at present" at present in China, BMS has been
' standard configuration ' component of new-energy automobile, compared with foreign countries, the state-of-charge of reliability, battery that China BMS is acquired in data
(SOC) estimation precision, heat management, equilibrium, safety management etc. have very big deficiency.Monomer, the little module electricity of many enterprises
Pond test result and in groups after result difference it is very big, be mainly manifested in single battery and meet safety and performance standard, and once
In groups, just it is difficult to ensure qualification in safety, service life, discharge capability etc..Single battery cycle charge-discharge up to 2000 times, at
Just only 1000 times after group, basic reason is exactly the BMS of not maturation.Since battery local power consumption is excessive, localized heat is generated
Amount, and information can not accurate transfer to driver, easily cause battery spontaneous combustion occur.Without compulsory test.The design of domestic BMS,
Production is substantially dominated by the third party of Battery Plant or its commission, after carrying out technology matching with power battery, is filled together
Tested on vehicle, substantially finally had the final say by vehicle factor for the project, flow and time of test, and vehicle factor for
The various technologies of BMS are not know theed inside story yet.In test process link, any problem that BMS occurs is exactly to solve on the spot substantially, finds one
It is a to solve one.Test through excessively taking turns, vehicle factor, Battery Plant and Electronics Factory realize that not new problem occurs, and BMS is together with dynamic
Power battery, that is, referable user.And use we research and develop BMS+GSM all-in-one machines, can when product small-lot testing,
The data acquired by BMS+GSM all-in-one machines, so that it may to realize that far-end fault diagnoses, remote firmware updating.BMS detections are not belonging to
The working range of power battery compulsory test, nearly 20,000,000 yuan of China Northern Motor Vehicle Research Ins.'s cost set up international advanced
The problems such as BMS inspection centers, basic reason are exactly that they have found, spontaneous combustion, function decaying occur for battery is frequently not to be happened to fill
It discharges link, but using link, and BMS+GSM all-in-one machines, link, the automatic of life-cycle can be used to detect simultaneously in user
The Parameters variation of storage battery provides data foundation for the upgrading of BMS.
