According to , for low currents charging and discharging battery losses are equal, while for higher currents, the discharging losses are approximately 10% more compared to the charging losses. Therefore, the battery percentage charging losses for 10Amps are 0.64%, and for 70Amps are 2.9%.
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.
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.
Losses can be higher, up to 30 %, or lower, below 10 %, mainly depending on the recharge voltage used (low or high voltage). An average loss of 15 % was considered for the charging set, in line with data published for some studies (Sears et al., 2014, Apostolaki-Iosifidou et al., 2017, Kostopoulos et al., 2020.
A reasonable range for battery charging losses is estimated to be between 5% and 20%, with an average value of approximately 10% [7,47, . Efficiency is computed as 100% minus the loss (%).
