American Norm
UL2580:2011 battery for electric vehicles essentially assesses the unwavering quality of battery misuse and the capacity to safeguard faculty in the event of misuse. The standard was updated in 2013.
SAE has a gigantic and ideal standard framework in the auto field. SAEJ2464:2009 security and misuse trial of battery-powered energy capacity arrangement of electric and crossover electric vehicles gave in 2009 It is an early cluster of vehicle battery misuse test manuals applied in North America and the world, which plainly calls attention to the extent of use of each test thing and the information to be gathered, and furthermore gives ideas on the quantity of tests expected for the test project.
SAEJ2929:2011 security standard for electric and cross breed lithium battery framework gave in 2011 is a wellbeing standard proposed by SAE on summing up different power lithium battery related norms gave previously, including two sections: routine test and unusual test that might happen during driving of electric vehicles.
SAEJ2380:2013 vibration trial of electric vehicle battery is an exemplary norm for vibration trial of electric vehicle battery. In view of the factual consequences of vibration load range assortment of genuine vehicle driving out and about, the test technique is more in accordance with the vibration circumstance of genuine vehicle and has significant reference esteem.
other association principles
The U.S. Division of energy (DOE) is primarily answerable for energy strategy detailing, energy industry the board and energy related innovation innovative work. In 2002, the U.S. government laid out the “FreedomCAR” project, and progressively gave the FreedomCAR power helped half and half electric vehicle battery test manual and the maltreatment test manual of energy stockpiling framework for electric and cross breed electric vehicles.
The German car industry affiliation (VDA) is basically answerable for different norms of similar German car industry.The guidelines gave incorporate VDA2007 battery framework test for half breed electric vehicles, which is mostly focused on the presentation and unwavering quality trial of lithium-particle battery framework for mixture electric vehicles.
Financial Commission for Europe (ECE) R100.2 uniform arrangements on the endorsement of vehicles as to unique necessities for electric vehicles It is the particular prerequisites formed by ECE for electric vehicles, which is separated into two sections: the initial segment normalizes the engine security, battery-powered energy capacity framework, practical wellbeing and hydrogen discharge of the entire vehicle, and the subsequent part is the new unambiguous prerequisites for the wellbeing and dependability of battery-powered energy capacity framework.
Standard investigation of force lithium particle battery
Extent of use
IEC62660 series is focused on the trial of battery unit and module level, while UL2580, SAEJ2929 and ISO12405 series are relevant to the trial of battery pack and battery framework. Notwithstanding IEC62660, different norms fundamentally include battery pack or framework level testing. SAEJ2929 and ECER100.2 even notice vehicle level testing. This shows that the definition of global principles assesses the utilization of batteries in the entire vehicle, which is more in accordance with the requirements of viable applications.
Test thing content
In general, all test things can be isolated into two classes: electrical execution and security unwavering quality, and wellbeing dependability can be separated into mechanical dependability, natural unwavering quality, misuse dependability and electrical dependability.
Mechanical unwavering quality, which mimics the mechanical pressure of the vehicle during driving, like vibration, and reenacts the unevenness of the vehicle out and about; Natural dependability, which recreates the resistance of the vehicle in various environments. For instance, the temperature cycle reproduces what is happening of the vehicle when the temperature contrast among day in and day out is enormous or driving ever changing in cold and hot regions; Misuse unwavering quality, like fire, to examine the wellbeing of the battery in the event of ill-advised use; For electrical dependability, for example, security test things, it is essential to research whether the battery the executives framework (BMS) can assume a defensive part at a crucial time.
As far as battery cells, IEC62660 is separated into two autonomous norms IEC62660-1 and IEC62660-2, comparing to execution and unwavering quality tests individually.
As far as battery pack and battery framework testing, American guidelines cover the most test things concerning electrical execution and dependability. As far as execution test, DOE/id-11069 has more test things than different norms, for example, half breed beat power trademark (HPPC), activity set point soundness, schedule life, reference execution, impedance range, module control review test, warm administration burden and framework level test joined with life check.
The examination technique for electrical execution test results is presented exhaustively in the supplement of the norm. Among them, HPPC test can be utilized to distinguish the pinnacle force of force lithium battery. The inferred DC inward obstruction test strategy has been broadly used to concentrate on the inner opposition attributes of battery. As far as dependability, UL2580 has more test things than different norms: uneven battery pack charging, endure voltage, protection, coherence test and cooling/warming security framework issue test. It likewise incorporates the fundamental security test for battery pack parts on the creation line. As far as BMS, cooling framework and insurance circuit plan, the security audit necessities are reinforced. SAEJ2929 proposes to lead issue investigation on each piece of the battery framework and save important records, including improvement estimates that are not difficult to recognize shortcomings.
ISO12405 series norms incorporate both battery execution and security. ISO12405-1 is a battery execution test standard for high-power applications, and ISO12405-2 is a battery execution test standard for high-energy applications. The previous incorporates cold beginning and hot beginning.
Not quite the same as different principles, SAEJ2929 and ECER100.2 both include high voltage security prerequisites and have a place with the wellbeing class of electric vehicles.
Seriousness
For similar test thing, various guidelines have likenesses and differences.For model, with respect to the condition of charge (SOC) of the test, ISO12405 expects that the SOC of force battery is half and that of energy battery is 100 percent; ECER100.2 requires the SOC of the battery to be over half; UN38.3 there are various necessities for various test things, and some test things need reused batteries.
Likewise, high reproduction, warm test, vibration, effect and outer short out should be tried with a similar example, which is more severe. For vibration test, ISO12405 expects tests to vibrate at various surrounding temperatures. The suggested high temperature and low temperature are 75 ℃ and – 40 ℃ separately.
Concerning the fire test, the trial strategy and boundary setting in ISO12405.3 are preheating, direct fire and circuitous fire by touching off the fuel. There is no time for the fire to douse. The fire test in SAEJ2929 is not the same as the previous. It expects that the example be put in a warm radiation compartment, quickly raise the temperature to 890 ℃ inside 90s and save it for 10min, And no part or substance will go through the metal lattice put external the test.
