Energy Storage Testing
The Advanced Vehicle Testing Activity is tasked by the U.S. Department of Energy's Vehicle Technologies Office to conduct various types of energy storage testing and demonstration activities.
Electric Drive and Advanced Battery and Components Testbed (EDAB)
The primary focus of the EDAB testing is to capture real world performance, capacity characteristics, and operating conditions of the subject ESS. On-road driving and charging operation of the ESS is conducted on a daily basis that is representative of typical driving and charging patterns. To quantify the ESS capacity and performance characteristics, a reference performance test is conducted at regular intervals throughout the on-road testing (every 1,500 to 2,000 miles of driving and charging).

Best Practices for Emergency Response to Incidents Involving Electric Vehicles Battery Hazards
The Advanced Vehicle Testing Activity at the Idaho National Laboratory (INL) was tasked by the U.S. Department of Energy and the U.S. Department of Transportation to develop a first responder program for electric drive vehicles and their energy storage systems. INL partnered with the National Fire Protection Association (NFPA) and NFPA's research arm, the Fire Protection Research Foundation to conduct a research program to develop the technical basis for best practices for emergency response procedures for electric drive vehicle battery incidents, with consideration for certain details including: suppression methods and agents; personal protective equipment (PPE); and clean-up/overhaul operations. A key component of this project goal was to conduct full-scale testing of large format Li-ion batteries used in today's electric drive vehicles. The below report and appendices summarize these tests, and includes discussion on the key findings relating to best practices for emergency response procedures for electric drive vehicle battery incidents.

Fast Charge Effects on Battery Life and Vehicle Performance Study
Four model year 2012 Nissan Leaf battery electric vehicles were instrumented with data loggers and are being operated over a fixed on-road test cycle. Each vehicle is charged twice daily, with two vehicles charged at AC Level 2 (L2), and two DC fast charged (DCFC) with a 50kW charger. The traction battery packs are removed and tested when the vehicles were new, and at 10,000 mile intervals. Battery tests include constant current discharge capacity, electric vehicle power characterization, and low peak power tests. The testing will continue to at least 50,000 miles at which point the battery testing results will determine if testing continues in additional 10,000 mile increments.
