What is the state of charge indicator?

looking at the readings on the indicators. The state of charge indicator holds the sum- mary that most users will focus on. 44 Figure 20: Charge termination through the third charge termination parameter. The dialog box in figure 20 recommends the user to disconnect the charger following failure of the first two charge termination methods.

Why do we need a battery performance report?

The document provides the basis for the development of homogenized performance metrics and a transparent reporting methodology at cell level, necessary for the reliable benchmarking of battery chemistries.

How to implement the recommended reporting methodology in battery research?

For a successful implementation, the suggested reporting methodology needs to be adopted by most scientists and implemented in all battery research projects for monitoring the progress beyond the state-of-the-art. Editors and Board members of high- level scientific journals could greatly assist in the implementation of such recommendations.

How do rechargeable batteries work?

Rechargeable batteries operate under the principle that electrochemical reactions at each of the electrodes are reversible. NiMH just like the other rechargeable batteries operates on their ability to absorb, release and move hydrogen between electrodes within the cell. The most basic components of a cell are Electrodes (anode and cath-

Why is performance evaluation and comparison of battery technologies so difficult?

In this rapidly evolving field, while key performance indicators can be readily accessed, the performance evaluation and comparison of battery technologies remain a challenging task, due to the huge variation in the quality and quantity of data reported and the lack of a common methodology.

What is the discharge voltage of a rechargeable battery?

The discharge voltage of a rechargeable battery is the closed-circuit voltage during discharge . It is affected by the current and ambient temperature. Both NiMH and NiCad have a 1.25v nominal voltage (this is the battery voltage) compared to 3.6 v of
