Develop, test and integrate batteries according to the standards
Annex 8 provides detailed information on testing procedures specific to RESSs, which include the following: The device is then placed in a convection oven or climatic chamber, and the temperature of the oven or chamber is gradually increased to a pre-determined level. Valence offers a proven technology and manufacturing infrastructure that delivers TS and IS approved products and processes, including an extensive global patent portfolio.
Tests Descriptions Vibration Verifies the safety performance of an RESS under vibration conditions similar to those experienced under normal vehicle operations. Verifies the safety performance of an RESS under vibration conditions similar to those experienced under normal vehicle operations.
Mechanical integrity Evaluates the safety performance of an RESS under contact loads that might be experienced in vehicle crash conditions. The device under test is crushed between a resistance plate and a crush plate with a specified force, onset time and hold time.
This sweep is repeated 12 times for a total test period of three hours. In some cases, testing values that differ from those presented in Annex 8 may be used, for example when a motor vehicle manufacturer presents simulations and results that demonstrate the appropriateness or preferability of an alternative approach. These tests include vibration testing, thermal shock testing, fire resistance immersion in fuel fireover-temperature, over charge and over discharge testing. Oct 23, — Valence Technology, Inc.
This article summarizes the new testing requirements. Originally published inthe regulation was revised in to keep pace with new technologies. The device under test is subject to both direct and indirect exposure to a flame that has been produced by burning commercial fuel.
What revision 2 of ECE-R means for rechargeable battery manufacturers | TÜV SÜD
The regulation provided a separate approval path for RESSs most often, rechargeable battery packsand d100 a number of tests exclusively applicable to these systems. Valence has completed this most challenging series of tests to help our customers through the arduous ECE R Revision 2 type approvals for battery powered vehicles. The tests are intended to ensure the safe operation of rechargeable batteries under anticipated operating conditions, and to provide a greater level of safety for vehicle drivers and passengers.
Assesses the resistance of an RESS to sudden changes in temperature similar to those experienced in actual environmental conditions. Specific technical requirements are found in approximately separate regulations, addressing vehicle cee like lighting and instrumentation, operational characteristics including crashworthiness or environmental compatibility.

U-Charge is a registered trademark of Valence Technology. This result provides clear and conclusive evidence of the safety and suitability of the Valence U-Charge lithium ion battery modules for the rigors of commercial EV g100.
Mechanical shock Verifies the safety performance of an RESS under inertial loads that may occur in vehicle crash conditions. This testing negates the need for the vehicle manufacturer to repeat any of sce tests during their final sign off with IDIADA which r10 reduces OEM time to market, no matter where they are located in Europe. The second revision of R introduces new testing requirements for manufacturers of rechargeable battery systems ecce electric vehicles, but also modifies the current type approval scheme, a change that is likely to increase competition in the RESS marketplace.
Valence produces a range of safe, proven lithium ion battery modules that can be scaled to any capacity up to V using a Valence proprietary Battery Management System BMS. The device under test is repeatedly charged and discharged with a steady current to increase the temperature of cells. For more information please visit lithiumwerks.
For more information, contact us at e-mobility tuv-sud. RESS manufacturers and motor vehicle manufacturers should take steps now to address the new type approval requirements ahead of the July mandate. Valence Technology is a global leader in the development and manufacture of safe, long-life modular lithium iron magnesium phosphate advanced energy ecce solutions.
The device under test is stored for at least six hours at 60 o C, followed ee six hours at o C. Take the next step How can we help you? Published inthe second revision of R implemented significant changes in the type approval process applicable to motor vehicles and Rechargeable Energy Storage Systems RESSs.
Evaluates the safety performance of an RESS under contact loads that might be experienced in vehicle crash conditions.
Annex 8 provides detailed information on testing procedures specific to RESSs, which include the following:.
Conclusion The second revision of R introduces new testing requirements for manufacturers of rechargeable battery systems for electric vehicles, but also modifies the current type approval scheme, a change that is likely to increase competition in the RESS marketplace.
Back to contents page. This cycle is repeated five times, followed by storage of the device at ambient temperatures for 24 hours. Assesses the resistance of an RESS to exposure from a fire originating outside of a vehicle, to determine whether a driver and passengers have sufficient escape time.
With the introduction of these new testing requirements, which take effect in July and become mandatory in Julythe responsibility for obtaining type approval for a rechargeable battery may also shift to the RESS manufacturer. Fire resistance Assesses the resistance of an RESS to exposure from a fire originating outside of a vehicle, to determine whether a driver and passengers have sufficient escape time.
The device under test is charged until the device automatically interrupts or limits the charging, or until the device is charged to twice its rated capacity. The actions of the Forum are based on the so-called Agreement, under which the European Union and nearly 60 other signatory countries agree to apply a common set of technical specifications to motor vehicles manufactured or sold within their countries, and to allow entry to motor vehicles manufactured in other countries that meet those specifications.
Verifies the safety performance of an RESS under inertial loads that may occur in e100 crash conditions. The device under test is accelerated exe decelerated at speeds specified in the tables accompanying the Regulation, and the actual gravitational fce is compared with the values specified in the tables.
In addition to its corporate headquarters in Texas, Valence Technology has a research and development center in Nevada, a European sales office in Northern Ireland, manufacturing facilities and APAC sales operations in China, and global fulfillment centers in North America and Europe.
