Batteries performance during discharge, evaluation

The alloys recently investigated in the fabrication of Ni-MH batteries include the AB5 (LaNij) type and ABj (zirconium vanadium [ZrVj]) type. During the evaluation of these alloys, the material scientists failed to explore critical performance characteristics of the alloys other than the discharge capacity and progressive... 

The capacity test of a traction battery is performed not only for quality assurance, but also to evaluate the endurance of the battery during operation. The capacity test is the only way to get a view of the electrical power of a battery. The test is described in EN 60 451, Part 1, as a discharge with a constant current I5 (A), compensation of the temperature by 0.6% per degree if the electrolyte temperature differs from 30 °C. To execute a test qualified testing equipment and educated staff are needed.
