The cause of power loss. According to Adac, there are several causes of power loss. First, current is lost through the wiring to the battery. With a standard charger, the power loss is around 4% due to cabling, where with the Wallbox it is only around 1%. Also, there is always power loss through the on-board charger, regardless of the method.

Do battery electric vehicles lose energy during charging?
The present study, that was experimentally conducted under real-world driving conditions, quantitatively analyzes the energy losses that take place during the charging of a Battery Electric Vehicle (BEV), focusing especially in the previously unexplored 80%–100% State of Charge (SoC) area.
What are the charging losses of a car?
A detailed breakdown of charging losses, drivetrain efficiency, and overall energy consumption for one of the vehicles is provided. Finally, the results are discussed with reference to avoidable CO 2 emissions. The charging losses of the tested vehicles range from 12.79 to 20.42%.
What is a breakdown of charging losses?
A breakdown of the charging losses is presented without going into the details of the charging process, e.g., the set amperage or the number of phases used. Ref. [ 7] breaks down the influence of the charging losses more precisely according to the amperage. The focus of this study is on the integration of electric vehicles into the power grid.
What is the percentage charging loss for a 10amp battery?
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%.
Are EV battery losses localized in EV charging and discharging?
The results presented in section 4 show that losses are highly localized whether in EV charging or in GIV charging and discharging. 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.
What is EV charging loss?
This loss is more pronounced during AC charging since the conversion happens inside the vehicle. In contrast, DC fast chargers perform this conversion externally, reducing these losses. Measuring EV charging loss involves comparing the amount of energy drawn from the grid to the energy stored in the vehicle’s battery.
