Effective power conversion is essential to achieving maximum performance, longevity, and range in electric vehicles (EVs). The vehicle''s subsystems are powered by converting the energy stored in the batteries into forms that can be used.
A typical lithium-ion (Li-ion) battery voltage, for example, can change from 4.35 V down to 2.5 V during the discharge cycle. If we need to generate a fixed voltage within this range, the first solution that comes to mind is a non-inverting buck-boost converter. But is this always the best choice?
The applications of lithium-ion batteries (LIBs) have been widespread including electric vehicles (EVs) and hybridelectric vehicles (HEVs) because of their lucrative characteristics such as high energy density, long cycle life, environmental friendliness, high power density, low self-discharge, and the absence of memory effect [, , ].
Choosing the right converter topology for a power supply usually starts by considering input and output voltages. If the input voltage is always higher than the required output voltage, a buck converter is the first choice, and if the input voltage is always lower than the required output voltage, a boost converter is the best bet.
However, for a more suitable and sustainable solution for EV batteries, the entire battery chemistry has been proposed to change by replacing the Li-ion with the other monovalent ions such as Na, K or by multivalent ions such as Mg, Zn, Al, and Ca, etc.
In the measurements, the battery is discharged at constant current, resistance or power, while the DC/DC converter generates fixed output voltages, unless it is out of regulation. Figure 3, Figure 4 and Figure 5 show the measured battery life achieved with the three devices used to generate voltages from 3 V to 4 V.
One possible discharge curve of a Li-ion battery is shown in Figure 1. For this particular battery it can be seen that the voltage changes in a relatively large range from 4.2 V down to 2.8 V after which the output voltage rapidly drops, the internal resistance rises, and the battery is depleted.
Effective power conversion is essential to achieving maximum performance, longevity, and range in electric vehicles (EVs). The vehicle''s subsystems are powered by converting the energy stored in the batteries into forms that can be used.
