    Testing first distinguishes between battery life decay mechanisms use or calendar dependent and then assesses the impacts of current levels low, high and temperature. Battery Life Decay Mechanisms Battery life decay mechanisms can be categorized as calendar or use dependent. Cycle life acceleration is more problematic, as its decay mechanism is more difficult to accelerate through established techniques. High-precision battery testing has recently been proposed as a method to accelerate the understanding of cycle life—based decay mechanisms Smith et al. To make future life predictions, it is necessary that the precision of the test data be at least as good as the decay per cycle that is being predicted. By closely measuring current, voltage, and time during a battery test, it is possible to achieve the parts per million ppm level of measurement precision needed to predict hundreds and thousands of cycles into the future. Low Current To understand the impact of imprecise battery measurements, the example of coulombic efficiency CE in consumer electronic cell life requirements is shown in Figure 1. Coulombic efficiency is defined as the number of electrons that leave a battery divided by the number that entered.

    However when the tester error is reduced to 50 ppm, the predicted future capacity can be determined with more confidence. Recognizing this opportunity for improvement, there has been growing interest in research on high-precision battery testing.

    Current academic systems have achieved ppm error in terms of coulombic efficiency, with a goal of 10 ppm for future systems Dahn et al. It should be noted that these systems are at low current rates single-digit amps at the most.

    High Current Automotive battery testing must demonstrate the capacity to support currents of at least several hundred amps, as would be typical of vehicle conditions.

    The range of power and corresponding current demands varies by vehicle type.

    Temperature Another significant challenge in testing at high currents is mitigation of the resulting temperature changes in the test cells and tester e. For the test automotive cell, a thermal image can reveal temperature gradients.

    The order of magnitude of the gradient can vary widely depending on cell design and test pattern run, but its orientation remains the same. At the top of the cell, the connecting terminals serve as excellent thermal wicks thanks to the highly thermally conductive metals used. By coupling the intimate cooling capacity of the TEs with feedback cell temperature and feedforward current delivery pattern and resulting cell-driven temperature change , it is possible to neutralize temperature fluctuations during the testing and study their effect e.

    As the technology and systems have evolved, FMVSS has been revised numerous times since it was first issued in With the recent application of lithium ion batteries to automotive applications, the National Highway Traffic Safety Administration NHTSA has conducted research on the safety behavior of the technology.
