Loss in the battery and in PEU depends on both current and battery SOC. Quantitatively, the PEU is responsible for the largest amount of loss, which varies widely based on the two aforementioned factors. In this section, engineering solutions for reducing losses are explored.
Yes. Note that all the current flowing through your process also flows through the battery. This means that if the internal resistance of the battery is R (i) and the current you measure flowing through your process is I (p), then the power loss in the battery is equal to (I (p))^2 x R (i).
System analysis Battery losses are due to several factors, among which are undesired electrochemical reactions within a battery, bad battery condition management by a battery management system (BMS), and cell warming due to internal resistance . Accounting for such losses from a theoretical point of view is beyond the scope of this paper.
The losses occurring in the battery and in the PEU are simultaneously assessed during the experiments. Each experiment consists of neutral amp-second round-trips applied at the DC bus level, or in other words, same number of coulombs are charged to and discharged from the battery.
The increased throughput makes measurement of power loss important to achieve efficient operation. Round-trip power losses from the grid entry point to the storage battery are measured, through a series of experiments that put the system under charging and discharging cycles.
These previous studies supported this study's decision to vary SOC and current as parameters affecting battery internal losses. Regarding other EV components, the PEU losses consist of two parts: stand-by losses inherent in the electronics, and Joule effect losses proportional to the square current .
