SAE J2464 DOWNLOAD

The rollover test is an exception to this. The temperature of the RESS to be recorded at several external and internal where applicable locations as a function of time. If the ECSS is equipped with liquid cooling, the coolant shall be present but not circulating. In the absence of more specific requirements by the test sponsor, the measurement accuracies in Table 2 shall be considered acceptable. SAE invites your written comments and suggestions.

The concentration of the released hazardous substances shall be scaled to the full RESS pack for quantitative comparison and scaled to a volume appropriate to human exposure in the vehicle. The DUT may be placed into a tank filled with water or may be placed in an empty tank and water pumped into the tank to fully submerge the DUT.

Unless otherwise specified, the latest issue of SAE publications shall apply. If this maximum system sas current k2464 not known for the eventual application, high-rate charging should be performed at a charge rate of 3C.

Additional cells may be required if Thermal Stability Limit is not known prior to tests. The test temperature is controlled by thermocouples mounted on the interior surface of the fixture, with the device under test placed in the center k2464 the fixture such that it does not contact the fixture walls. The kinetic energy of flying debris from the RESS may be sufficient to cause damage as well.

If the ECSS ignites, it may be extinguished with a sqe appropriate j24644 the technology. It describes a body of tests which may be used as needed for abuse testing of electric or hybrid electric vehicle Rechargeable Energy Storage Systems RESS to determine the response of such electrical energy storage and control systems to conditions or events which are beyond their normal operating range.

A sketch of such a test fixture is shown in Figure 3.

Quality plan and control procedures of the test organization should be documented. However, experience has shown that it is often prudent to standardize the data reduction formats prior to testing. Temperature of the ECSS case as a saee of time.

The choice of storage DOD and temperature values is made by the test sponsor based on intended application and the particular battery technology to be tested. This test applies only to cells that have a shutdown separator.

The flammability of any solids, liquids and gases released during the mechanical abuse tests will be analyzed according to 4. The ECSS shall remain at each extreme for a minimum of u2464 h at the cell level, 6 h at the module level, or as required to reach uniform temperature at the pack level.

Potential and resistance of the ECSS case with respect to the positive and negative terminals before and after the test. See Figure 2 for a photograph of an example of a cylindrical cell crush fixture for cells. The method used to create a thermal runaway in one cell will be described and documented in the report.

Unless otherwise stated, passive protection devices that are integral to the RESS shall remain operational throughout the test. Tests are grouped into four categories: Mass of the DUT will be measured before and after the test to determine if venting and loss of contents sqe occurred. SAE invites your written comments and suggestions.

Develop, test and integrate batteries according to the standards

All test articles will be observed for a time period of at least 1 h or until such time that said xae article is judged safe to handle after each test unless specifically stated otherwise. This guideline is taken from j24464 American Industrial s Hygiene Association. This test provides understanding of the potential that single cell failure may propagate within series connected cells in a module.

Replacement or repair needed. Prior to this test, all active protective devices shall be disabled. ECSS voltage, as appropriate. The lower limit of flammability in air is used for flammable gases and liquids. The low level shock is a robustness test which an ECSS will generally survive without damage.

For some electrical architectures, the full pack must be present during the module tests to ensure all potential electrical interactions are included in the test.

Note that pack level hazardous substance monitoring 4. It lists all of the documents referred to in jj2464 plan. Testing at other states of charge may be performed if the cell manufacturer has information that thermal saae is degraded at other SOCs. Manufacturers will identify any hazardous materials that may be released by their products during abusive testing using standard analytical techniques.
