Nicaragua battery technical parameters

The state of the battery is mainly defined by two parameters: state of charge (SOC) and, state of health (SOH). Both parameters influence performance in the battery and are dependant on each other (Jossen et al., 1999).

In the automotive industry, the validation of the batteries are approved by prototype test, even though simulation is less cost. There are still limitations to correlate experimental test with CAE models due to complexity in non-linearities in the behaviour of the parts.

The battery state is utilized as an input for electrical management and control and for the user to estimate the expected lifetime of a battery. The battery state estimations are critical for the BMS optimization and function in order to provide reliable operations and safety management to the battery pack (Piller et al., 2001).

A normal alkaline cell, for instance, has a nominal voltage of 1.5 volts, while a typical lithium-ion cell has a nominal voltage of 3.7 volts. It is crucial to understand that a battery's nominal voltage is used to classify and compare batteries, whereas the actual voltage of a battery changes during the course of its discharge cycle.

These criteria are essential for a number of reasons: Selection and Sizing: Engineers can select the best battery for a certain application by knowing the parameters and calculating the size and number of batteries required to match the specifications.

Due to the application of battery technology is relatively new in electric vehicles, standardization of battery tests are limited and not yet properly defined. For example, the methods and procedure vary between standards given discrepancy in the results.
