One of the demonstrations we often set up at battery conferences is to use a source measure unit (SMU) to measure the internal resistance of an energy storage device such as a battery or a fuel cell. In such demonstrations, the SMU changes the load current from the battery operating current or the polarizing current to the open circuit potential and simultaneously measures the change in cell voltage. In this “current interrupt method,” the battery’s internal resistance is equal to the change in voltage divided by the change in current.

The continual addition of smartphone features and functionality, combined with users’ growing dependence on them for both business and personal use, has made battery life and reliability increasingly vital. The digital transmission signals that these devices rely on to operate require quick pulses of current from the battery. However, these pulses can also cause the battery’s instantaneous voltage to drop below the phone’s minimum operating voltage, which can temporarily interrupt the flow of power from the battery. To solve this problem, engineers performed a series of tests on multiple battery chemistries to determine whether placing a supercapacitor in parallel with the battery could effectively improve the life of the battery and the quality of the power it provides.

The storage system used in electric vehicles (EVs) and hybrid electric vehicles (HEVs) is a key component of the drivetrain and defines the vehicle’s performance. To tap the complete potential of storage systems, it must be possible to model, simulate and test them holistically and seamlessly.
