UNECE R Title: Battery electric vehicle safety. Link: Commission: ECE/ TRANS/WP Scope: The following prescriptions apply to safety requirements. Specific UN ECE regulations for (H)EV: – ECE R safety requirements. – ECE R energy consumption. – ECE R 85 measurement of electric drive power. 6. ECE R The ECER standard is applicable for EV’s, vehicle category M+N and capable of a topspeed above 25 km/hr. So it is likely that this standard is.
Valence has completed this most d100 series of tests to help our customers through the arduous ECE R Revision 2 type approvals for battery powered vehicles. Valence Technology is a global leader in the development and manufacture of safe, long-life modular lithium iron magnesium phosphate advanced energy storage solutions.
Evaluates the safety performance of an RESS under contact loads that might be experienced in vehicle crash conditions. Assesses the resistance of an RESS to sudden changes in temperature similar to those experienced in actual environmental conditions. The device under test is stored for at least six hours at 60 o C, followed by six hours at o C.
This article summarizes the new testing requirements. 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. Under the terms of the Agreement, motor vehicles and components that receive type approval in one signatory country must be accepted for importation, sale or use in all other signatory countries although a number of non-EU signatory countries are reportedly requiring retesting in laboratories located in their own countries.
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.
Assesses the resistance of an RESS fce 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 accelerated or decelerated at speeds specified in the tables accompanying the G100, and the actual gravitational force is compared with the values specified in the tables. This sweep is repeated 12 times for a total test period of three hours.
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.
Specific technical requirements are found in approximately separate regulations, addressing vehicle components like lighting and instrumentation, operational characteristics including crashworthiness or environmental compatibility. Valence battery module in test chamber ECE R Revision 2 type approval is now required on new electric vehicle types entering service in Europe.
Published inthe second revision of R implemented significant changes in the type approval process applicable to motor vehicles and Rechargeable Energy Storage Systems RESSs.
Valence Technology is the first lithium battery producer to have passed these strenuous tests at the module r10 level. Tests Descriptions Vibration Verifies the safety performance of an RESS under vibration conditions similar to those experienced under normal vehicle operations. The regulation provided a separate approval path for RESSs most often, rechargeable battery packsand introduced a number of tests exclusively applicable to these systems.
The device under test is crushed between a resistance plate and a crush plate with a specified force, onset time and hold time. Fire resistance Assesses the resistance of an RESS to eec from a fire originating outside of a vehicle, to determine whether a driver and passengers have sufficient escape time.
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.
This ecr 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 applications.
We trust that existing and new customers alike will see the benefit through reduced testing costs and will give our customers confidence to use Valence in all types of commercial EV applications. These tests include vibration testing, thermal shock testing, fire resistance immersion in fuel fireover-temperature, over charge and over discharge testing.
Mechanical shock Verifies the safety performance of an RESS under inertial loads that may occur in vehicle crash conditions.
Valence Completes ECE R Revision 2 Testing – Lithium Werks
The device under test is subject to a vibration having a sinusoidal waveform with a logarithmic sweep between 7 Hz and 50 Hz and back to 7 Hz in the span of 15 minutes.
The BMS provides contactor control and module string balancing while providing a communication interface via CANBus to the outside world from the Valence modules. Annex 8 provides detailed information on testing procedures specific to RESSs, which include the following: Annex 8 provides detailed information on testing procedures specific to RESSs, which include the following:.
Valence offers a proven technology and manufacturing infrastructure that delivers TS and IS approved products and processes, including an extensive global patent portfolio.
The impact of second revision R testing on RESS and motor vehicle manufacturers RESS testing requirements under the second revision of R are more extensive than previous versions of the regulation, and the responsibility for obtaining type approval might shift to RESSs manufacturers.
Valence Completes ECE R100 Revision 2 Testing
The device under test is subject to an intentional short circuit by connecting the positive and negative terminals of the device, using a connection with a specified resistance. Mechanical integrity Evaluates the safety performance of an RESS under contact loads that might be experienced in vehicle crash conditions. Verifies the safety performance of an RESS under inertial loads that may occur in vehicle crash conditions. For more information please visit lithiumwerks. Back to contents page.
Thermal shock and cycling Assesses the resistance of an RESS to sudden changes in temperature similar to those experienced in actual environmental conditions. 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 device under test is subject to both direct and indirect exposure to a flame that has been produced by burning commercial fuel. In addition Valence has performed the testing for this new regulation, where possible, at the module level without the inclusion of the Valence Battery Management System BMSwhich provides system level protection through contactors and other safety devices.
RESS testing requirements under the second revision of R are more extensive than previous versions of the regulation, and the responsibility for obtaining type approval might shift to RESSs manufacturers.

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. This cycle is repeated five times, followed by storage of the device at ambient temperatures for 24 hours.
The goal of the Forum is to establish globally harmonized regulations for motor vehicles in order to remove barriers to international trade, promote road safety and protect the environment. What revision 2 of ECE-R means for rechargeable battery manufacturers. Oct 23, — Valence Technology, Inc.
