Abstract: The calculation of the battery power losses is very important for its operation in safe conditions. Determining the power losses will be important for choosing the cooling system of the battery and so, keeping the accumulator in the optimal range of temperatures, increasing also the lifetime, which reflects itself in price reduction.
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%.
First, power losses are extensively measured, from grid to the EV battery and back to the grid, under different conditions. These measurements are generalized by deriving functions to predict power losses.
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 (%). ...
According to the ADAC, you can lose between 10 and 25% of the total amount of energy charged. Quite a number, huh? And the thing is, you normally cannot avoid it - the energy simply gets lost on the way to your vehicle. But why is that? And what can you do to minimise energy loss when charging the battery? Let’s see!
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. ... ...
